(3) For the portion of "Compensation Actually Paid" that is based on year-end stock prices, the following prices were used: for 2022: $214.30 (2.8% increase from prior year), for 2021: $208.51 (2.0% decrease from prior year), and for 2020: $212.70 (20.2% increase from prior year).

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | CAP versus TSR As shown in the chart below, the CEO's and average non-PEO NEOs' CAP values are reasonably aligned with Honeywell's TSR. This is primarily due to the Honeywell’s use of Performance Shares (PSUs), NQSOs and Restricted Stock Units (RSUs), which are tied directly to stock price and the Company’s financial performance. CAP vs HONEYWELL TSR | | |
| Compensation Actually Paid vs. Net Income [Text Block] | CAP versus Net Income The charts below reflect the relationship between the CEO and Average NEO CAP and Honeywell’s GAAP net income. The Company does not use net income to determine compensation levels, incentive plan payouts, or as a metric in our long-term incentive plans. Since long-term incentives comprise the largest portion of our NEOsʼ pay, and CAP values include multiple years of LTI awards, and only one year of annual incentives, the relationship between CAP and net income is less evident. CAP vs NET INCOME | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | CAP versus Segment Margin The chart below reflects the relationship between the CEO CAP and Average NEO CAP and Honeywell’s Segment Margin for the applicable reporting year. We consider segment margin to be the most important financial measure used to link pay to performance in 2022 due to the strong correlation with long-term share price growth. CAP vs SEGMENT MARGIN | | |
| Total Shareholder Return Vs Peer Group [Text Block] | TSR: Company versus Peer Group As shown in the chart below, the Company’s 3-year cumulative TSR is higher than the companies included in our industry index, Nasdaq Industrial Select Sector Index (XLI) reflecting strong out performance in 2022.

| Additional 402(v) Disclosure [Text Block] | As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information regarding executive pay and performance. The table below shows pay both as reported in the Summary Compensation Table (Summary Comp Table Total) for the applicable fiscal year and as “compensation actually paid” (CAP) for our principal executive officer (PEO) and as an average of all of our other named executive officers (Non-PEO NEOs) for the applicable fiscal year. Both Summary Comp Table Total pay and CAP are calculated in accordance with the requirements of Regulation S-K and may differ substantially from the manner in which the MDCC makes executive compensation decisions, which is described in the Compensation Discussion and Analysis beginning on page 57. The table below also shows (i) Honeywell’s cumulative total shareholder return (TSR), (ii) the TSR of the Nasdaq Industrial Select Sector Index (XLI), which we have used as our peer group for purposes of this table, (iii) Honeywell’s net income for the applicable fiscal year, and (iv) Honeywell’s performance with respect to a company-selected measure (CSM), which in our assessment represents the single most important financial performance metric used to link compensation actually paid to our NEOs for the most recently completed fiscal year to Honeywell’s performance. We selected Segment Margin as the CSM for the 2022 fiscal year. | | |
