Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATION On October 24, 2014 , the Company completed its acquisition of TF Financial Corporation ("TF Financial"), a savings and loan holding company, and its wholly-owned subsidiary, 3rd Fed Bank. Headquartered in Newtown, Pennsylvania, TF Financial operated eighteen branch offices in Pennsylvania and New Jersey and had acquisition date estimated fair values of approximately $801 million of assets, which included $595 million of loans, and $658 million of deposits. The assets and liabilities of TF Financial were recorded on National Penn's consolidated balance sheet at their preliminary estimated fair values as of October 24, 2014 , the acquisition date, and TF Financial's results of operations have been included in the Company's consolidated statements of income and comprehensive income since that date. The acquisition was valued at approximately $136 million , consisting of $58.4 million in cash and the issuance of 8,030,953 shares of the Company's common stock valued at $77.3 million , in exchange for 1,903,139 shares of TF Financial common stock. Based on a preliminary purchase price allocation, the Company recorded $44 million in goodwill and $4.8 million in core deposit intangibles as a result of the acquisition. The amount of goodwill recorded reflects the excess purchase price over the estimated fair value of the net assets acquired. Based upon further review of the purchased credit-impaired ("PCI") loan portfolio, the Company recorded an additional $0.7 million in goodwill during the first quarter of 2015. None of the goodwill is deductible for income tax purposes. Refer to Footnote 5 within this section for additional information related to the acquired loan portfolio.

As of June 30, 2015 and December 31, 2014 , accumulated other comprehensive income did not include any impairment related charges for the non-credit-related components of OTTI. The majority of the investment portfolio is comprised of U.S. Government Agency securities (mortgage-backed and collateralized mortgage obligations) and state and municipal bonds. For the investment securities in an unrealized loss position, the Company has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates, and the contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. At June 30, 2015 , gross unrealized losses totaled $11.6 million , and the gross unrealized losses of securities in an unrealized loss position for twelve months or longer totaled $7.8 million , of which $7.4 million is attributable to agency mortgage-backed securities and $0.4 million attributable to state and municipal securities and other. The Company evaluates a variety of factors in concluding whether securities are other-than-temporarily impaired. These factors include, but are not limited to, the type and purpose of the bond, the underlying rating of the bond issuer, and the presence of credit enhancements (i.e. state guarantees, municipal bond insurance, collateral requirements, etc.). As a result of its review and considering the attributes of the individual securities, the Company concluded that the securities were not other-than-temporarily impaired. Because the Company does not intend to sell these investments and it is not more likely than not it will be required to sell these investments before a recovery of carrying value, which may be maturity, the Company does not consider the securities in an unrealized loss position for twelve months or longer to be other-than-temporarily impaired. Other securities on the Company’s consolidated balance sheet totaled $67.1 million and $67.5 million as of June 30, 2015 and December 31, 2014 , respectively. The balance includes Federal Loan Home Bank ("FHLB") of Pittsburgh stock and Federal Reserve Bank stock. These securities lack a market, and as such they are carried at par/cost since their fair value is not readily determinable. The Company evaluates, and will continue to evaluate, these securities for impairment each reporting period and has concluded the carrying value of these securities is not impaired. During 2015 , the FHLB of Pittsburgh and Federal Reserve Bank repurchased an additional $0.4 million, net, of capital stock from the Company at par/cost. Also, during 2015 and 2014 the Company received and recorded dividends on its FHLB stock.

CONTINGENCIES	CONTINGENCIES In the normal course of business, the Company is named as a defendant in various lawsuits. Accruals are established for legal proceedings when information related to the loss contingencies indicates that a loss settlement is both probable and can be estimated. At June 30, 2015 , the Company did not have material amounts accrued for legal proceedings as it is the opinion of management that the resolution of such suits will not have a material effect on the financial position or results of operations of the Company. The outcome of legal proceedings is inherently uncertain, and as a result, the amounts recorded may not represent the Company's ultimate loss upon resolution. Thus, the Company’s exposure and ultimate losses may be higher or lower than amounts accrued or estimated as the reasonably possible exposure.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK - Continued The Company enters into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. In response, the Company enters into offsetting interest rate swaps with counterparties for interest rate risk management purposes. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Changes in the fair value of the customer and counterparty swaps are recorded net in the consolidated statement of income. Because these amounts offset each other, there was no impact on other operating income for the three and six months ended June 30, 2015 and June 30, 2014 .

Offsetting [Abstract]
BALANCE SHEET OFFSETTING	BALANCE SHEET OFFSETTING Certain financial instrument related assets and liabilities may be eligible for offset on the consolidated balance sheet because they are subject to master netting agreements or similar agreements. However, the Company does not elect to offset such arrangements on the consolidated financial statements. The Company enters into interest rate swap agreements with customers and financial institution counterparties. For additional detail regarding interest rate swap agreements refer to Footnote 10 within this section. In the event of default on, or termination of, any one contract, both parties have the right to net settle multiple contracts. Also, certain interest rate swap agreements may require the Company to receive or pledge cash collateral based on the contract provisions. The Company also enters into agreements to sell securities subject to an obligation to repurchase the same or similar securities, referred to as repurchase agreements on the consolidated balance sheet. Under these agreements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated balance sheet, while the securities underlying the repurchase agreements remain in the respective investment securities account, therefore there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities. The following table presents information about financial instruments that are eligible for offset: June 30, 2015 (dollars in thousands) Assets Gross Amount Gross Amounts Offset in the Balance Sheet Net Amounts Presented in the Balance Sheet Derivatives - Interest Rate Swaps $ 501 $ — $ 501 Liabilities Derivatives - Interest Rate Swaps $ 23,548 $ — $ 23,548 December 31, 2014 (dollars in thousands) Assets Gross Amount Gross Amounts Offset in the Balance Sheet Net Amounts Presented in the Balance Sheet Derivatives - Interest Rate Swaps $ 546 $ — $ 546 Liabilities Derivatives - Interest Rate Swaps $ 24,786 $ — $ 24,786 11.

FAIR VALUE MEASUREMENTS AND FAI

FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS In general, fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, which is not adjusted for transaction costs. Accounting guidelines establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted, quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Basis of Fair Value Measurement: Level 1 - Unadjusted, quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The types of instruments whose value is based on quoted market prices in active markets include most U.S. Treasury securities, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The Company does not adjust the quoted price for such instruments. The types of instruments whose value is based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most U.S. Government agency securities, state and municipal bonds, mortgage-backed securities, collateralized mortgage obligations, and corporate securities. Such instruments are generally classified within Level 2 of the fair value hierarchy and their fair values are determined as follows: • The markets for U.S. Government agency securities are active, but the exact (cusip) securities owned by the Company are traded thinly or infrequently. Therefore, the price for these securities is determined by reference to transactions in securities with similar yields, maturities and other features (matrix priced). • State and municipal bonds owned by the Company are traded thinly or infrequently, and as a result the fair value is estimated in reference to securities with similar yields, credit ratings, maturities, and in consideration of any prepayment assumptions obtained from market data. • Collateralized mortgage obligations and mortgage-backed securities are generally unique securities whose fair value is estimated using market information for new issues and adjusting for the features of a particular security by applying assumptions for prepayments, pricing spreads, yields and credit ratings. • Certain corporate securities owned by the Company are traded thinly or infrequently. Therefore, the fair value of these securities is determined by reference to transactions in other issues of these securities with similar yields and features. 12. FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued Level 3 classification is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Internal cash flow models using a present value formula along with indicative exit pricing obtained from broker/dealers are used to fair value Level 3 investments. Management changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows. Fair values for securities classified within Level 3 are determined as follows: • Certain corporate securities owned by the Company are not traded in active markets and prices for securities with similar features are unavailable. The fair value for each security is estimated in reference to benchmark transactions by security type based upon yields, credit spreads and option features. • Certain marketable equity securities which are not subject to ownership restrictions but are traded thinly on exchanges or over-the-counter. As a result, prices are not available on a consistent basis from published sources, and, therefore, additional quotations from brokers may be obtained. Additionally considered indications of pricing include subsequent financing rounds or pending transactions. The reported fair value is based upon the Company’s judgment with respect to the information it is able to reliably obtain. The Company utilizes a third-party service provider to assist with investment security pricing. Each quarter the Company performs an independent validation of the third-party security pricing by obtaining pricing from other sources and evaluating discrepancies to established tolerances for each security type, including a review of unchanged prices. Additionally, the Company evaluates the third-party service provider's pricing results by periodically reviewing the service provider's practices and procedures. Interest rate swap agreements are measured by alternative pricing sources with reasonable levels of price transparency in markets that are not active. Based on the complex nature of interest rate swap agreements, the markets these instruments trade in are not as efficient and are less liquid than that of the Level 1 markets. These markets do however have comparable, observable inputs in which an alternative pricing source values these assets to arrive at a fair value. These characteristics classify interest rate swap agreements as Level 2 measurements. The Company has the option to measure eligible financial assets, financial liabilities and Company commitments at fair value (i.e. the fair value option), on an instrument-by-instrument basis. The election to use the fair value option is available when an entity first recognizes a financial asset or liability or upon entering into a Company commitment. Subsequent changes in fair value must be recorded in earnings. The Company has not elected to apply the fair value option to any of its financial instruments at June 30, 2015 . 12. FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2015 and December 31, 2014 , by level within the fair value hierarchy.

For additional information regarding impaired loans, refer to Footnote 5. 12. FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued Fair value for loans held-for-sale is estimated based upon available market data for mortgage-backed securities with similar interest rates and maturities. Lower of cost or estimated fair value write-downs recorded on loans held-for-sale were zero as of June 30, 2015 and December 31, 2014 . The recorded investment in impaired loans totaled $50.4 million with a specific reserve of $7.9 million at June 30, 2015 , compared to $62.0 million with a specific reserve of $13.1 million at December 31, 2014 . Fair value for impaired loans is measured primarily on the value of the collateral securing these loans, less estimated costs to sell, or the present value of estimated cash flows discounted at the loan’s original effective interest rate. Appraised values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Fair value for OREO and other repossessed assets is estimated based upon its appraised value less costs to sell. Additional write-downs of $0.2 million were included in the period-ending OREO and other repossessed assets balance at June 30, 2015 . There were no additional write-downs included in OREO and other repossessed assets balance at December 31, 2014 . In addition to financial instruments recorded at fair value in the Company’s financial statements, disclosure of the estimated fair value of all of an entity’s assets and liabilities considered to be financial instruments is also required. For the Company, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. However, certain instruments lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. Also, it is the Company’s general practice and intent to hold its financial instruments to maturity and to not engage in trading or sales activities, other than mortgage loans held-for-sale. Fair values have been estimated using data that management considered the best available and estimation methodologies deemed suitable for the pertinent category of financial instrument. The estimation methodologies, resulting fair values and recorded carrying amounts are as follows: June 30, 2015 December 31, 2014 (dollars in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Assets Cash and cash equivalents $ 238,385 $ 238,385 $ 413,839 $ 413,839 Investment securities available-for-sale 1,598,351 1,598,351 1,530,661 1,530,661 Investment securities held-to-maturity 842,192 864,599 921,042 949,935 Loans held-for-sale 9,693 9,934 4,178 4,306 Loans, net of allowance for loan losses 6,073,972 5,989,795 6,051,604 5,957,399 OREO and other repossessed assets 5,186 5,186 4,867 4,867 Interest rate swap agreements 24,049 24,049 25,332 25,332 Interest rate locks — — 30 30 Liabilities Non-interest bearing deposits $ 1,200,631 $ 1,200,631 $ 1,085,158 $ 1,085,158 Interest bearing deposits, non-maturity 4,342,515 4,342,515 4,418,926 4,418,926 Deposits with stated maturities 1,190,338 1,185,802 1,225,661 1,223,210 Customer repurchase agreements 539,850 539,850 607,705 607,705 Federal Home Loan Bank advances and other borrowings 889,366 894,507 910,378 916,280 Senior long-term debt 125,000 119,608 125,000 127,250 Subordinated debentures 77,321 77,321 77,321 77,321 Interest rate swap agreements 24,049 24,049 25,332 25,332 Forward sale commitments 131 131 158 158 Interest rate locks 110 110 — — 12. FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued The fair value of cash and cash equivalents have been estimated to equal the carrying amounts due to the short-term nature of these instruments. Therefore, cash and cash equivalents are classified within Level 1 of the fair value hierarchy. The fair value of investment securities held-to-maturity has been estimated in a similar fashion to similar securities categorized as available-for-sale. Held-to-maturity securities include U.S. Government agencies, state and municipal bonds, collateralized mortgage obligations and mortgage-backed securities. These instruments are classified within Level 2 of the fair value hierarchy. The fair value of the loan portfolio has been estimated using a discounted cash flow methodology based upon prevailing market interest rates relative to the portfolios’ effective interest rate which includes assumptions concerning prepayment rates and net credit losses, and may not be indicative of an exit price. The loan portfolio is classified within Level 3 of the fair value hierarchy. The fair value of non-interest bearing demand deposits has been estimated to equal the carrying amount, which is assumed to be the amount payable on demand at the balance sheet date and therefore are classified within Level 1 of the fair value hierarchy. The fair value of interest bearing deposits excludes deposits with stated maturities and is based on the assumption that the exit value of the instruments would be funded with like instruments by principal market participants. These instruments are classified within Level 2 of the fair value hierarchy. The fair value of deposits with stated maturities is estimated at the present value of associated cash flows using contractual maturities and market interest rates. These instruments are classified within Level 2 of the fair value hierarchy. The fair value of customer repurchase agreements has been estimated at the present value of associated cash flows using contractual maturities and market interest rates for each instrument. These instruments are classified within Level 2 of the fair value hierarchy. The fair value of FHLB advances and other borrowings is determined based on current market rates for similar borrowings with similar credit ratings, as well as a further calculation for valuing the optionality of the conversion features in certain of the instruments. These instruments are classified within Level 2 of the fair value hierarchy. The fair value of the Company's senior long-term debt is based upon an unadjusted, quoted price (CUSIP: 637138AC2) and as such is classified within Level 1 of the fair value hierarchy. The fair value of subordinated debentures is estimated to equal their par amount as these instruments have floating interest rates based upon LIBOR and are callable at any time. These instruments are classified within Level 2 of the fair value hierarchy.

Compensation and Retirement Disclosure [Abstract]
PENSION PLAN	13. PENSION PLAN The Company has a curtailed, non-contributory defined benefit pension plan (National Penn Bancshares, Inc. Employee Pension Plan) covering substantially all employees of the Company and its subsidiaries employed as of January 1, 2009. The Company-sponsored pension plan provides retirement benefits under pension trust agreements based on years of service. Prior to April 1, 2006, benefits are based on the average of the employee compensation during the highest five consecutive years during the last ten consecutive years of employment. Beginning on April 1, 2006, eligible compensation was limited to $50,000 per year. The Company does not expect to make a contribution in 2015 because the plan’s funding credit balance will be applied toward reducing the contribution requirement. The Company’s expected long-term rate of return on plan assets is 7.25% . On February 12, 2010, the Company curtailed its pension plan effective March 31, 2010, whereby no additional service will accumulate for vested participants after March 31, 2010. Unvested participants still have the opportunity to meet the five year vesting requirement to earn a benefit. On October 24, 2014, the Company acquired the 3rd Fed Bank Retirement Plan as part of the acquisition of TF Financial. The plan is a non-contributory defined benefit pension plan which was frozen by TF Financial prior to the acquisition. The table below reflects the components of the combined net periodic benefit cost of the plans: (dollars in thousands) Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Service cost $ 96 $ 55 $ 128 $ 110 Interest cost 893 602 1,190 1,205 Expected return on plan assets (1,273 ) (735 ) (1,698 ) (1,470 ) Amortization of unrecognized net actuarial loss 187 78 250 155 Net periodic benefit cost (gain) $ (97 ) $ — $ (130 ) $ —

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Company’s operating segments, which are evaluated regularly by the Chief Executive Officer to decide how to allocate and assess resources and performance, are “Community Banking” and “Other.” The Company determines its segments based primarily upon product and service offerings and through the types of income generated. The Company’s community banking segment consists of commercial and retail banking. The community banking business segment is managed as a single strategic unit, which generates revenue from a variety of products and services it provides. Examples of products and services provided include commercial business loans, commercial real estate loans, residential mortgages and other consumer loans, and deposit and cash management services. Both commercial and retail banking are dependent upon deposits and various borrowings to manage interest rate and credit risk. The Company has also identified several other operating segments. These non-reportable segments include National Penn Wealth Management, N.A., National Penn Insurance Services Group, Inc., and the parent bank holding company and are included in the “Other” category. These operating segments do not have similar characteristics to the community banking operations and do not individually or in the aggregate meet the quantitative thresholds requiring separate disclosure. The operating segments in the “Other” category earn revenues primarily through the generation of fee income and are also aggregated based on their similar economic characteristics, products and services, type or class of customer, methods used to distribute products and services and/or nature of their regulatory environment. The identified segments reflect the manner in which financial information is currently evaluated by management. The accounting policies, used in this disclosure of operating segments, are the same as those described in the summary of significant accounting policies in the Company’s most recent Annual Report on Form 10-K. Reportable segment-specific information and reconciliation to consolidated financial information is as follows: As of and for the (dollars in thousands) Community Banking Other Consolidated Total assets $ 9,566,109 $ 38,205 $ 9,604,314 Total deposits 6,733,484 — 6,733,484 Net interest income (expense) 68,736 (1,901 ) 66,835 Total non-interest income 14,160 10,527 24,687 Total non-interest expense 45,373 8,587 53,960 Net income (loss) 27,430 (192 ) 27,238 For the (dollars in thousands) Community Banking Other Consolidated Net interest income (expense) $ 139,299 $ (3,782 ) $ 135,517 Total non-interest income 26,760 20,857 47,617 Total non-interest expense 91,177 17,365 108,542 Net income (loss) 54,592 (627 ) 53,965 15.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK - Continued The Company enters into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. In response, the Company enters into offsetting interest rate swaps with counterparties for interest rate risk management purposes. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Changes in the fair value of the customer and counterparty swaps are recorded net in the consolidated statement of income. Because these amounts offset each other, there was no impact on other operating income for the three and six months ended June 30, 2015 and June 30, 2014 . For additional analysis of the fair value of interest rate swaps refer to Footnote 12 within this section.
