     Re:  Advance Capital I, Inc. Funds, File No. 811-05127
          -------------------------------------------------

Dear Mr. Rupert:

      This letter responds to your telephone comments received by our legal
counsel, Paul Rentenbach, on Thursday, August 28, 2008, regarding the financial
disclosures contained in the annual report of Advance Capital I, Inc. Funds
(the "Funds"), which was filed with the Commission on Form N-CSR on
March 5, 2008.  We have organized the comments you presented and our responses
to such comments in the order in which they were delivered.

Comment 1:
  The Form N-CSR's filed by Advance Capital I, Inc. for the past several half
  years have not included the cover page of the form.  The cover page is
  required.

Response 1:
  The omission of the cover page in our past several filings was an oversight.
  The cover page was included in our Form N-CSR filed on September 4, 2008,
  and will be properly included in future Form N-CSR filings.

Comment 2:
  In the Financial Highlights tables beginning on page 10, the turnover rate
  should be shown only in full percentage points, not to any fractions of a
  point (i.e., 32.93% should be shown as 33%).

Response 2:
  The turnover rate will be shown in full percentage points in future
  financial statements.



Comment 3:
  The footnote on page 25 using the symbol "^^" is confusing. (Note:  the Edgar
  version of this filing uses "^^" and the printed version uses just one "^").
  First of all, there are no securities on that page that are marked with the
  "^^".  Secondly, the footnote says that for the Balanced Fund the total value
  of the Fund's securities on loan is $3,083,778.  Previously, on page 22, you
  state that the total value of the Balanced Fund's securities on loan is
  $74,139,994.  Which is correct?

Response 3:
  To address the first item, the symbol "^^" found on page 25 in Form N-CSR was
  an oversight and should have displayed the symbol "^".  The printed version
  of the annual report uses the correct symbol "^" in the footnote.  For the
  second item, the footnote on page 25 that states "the total value of the
  Fund's securities on loan is $3,038,778" refers to the fixed income
  securities in the Balanced Fund.  Likewise, the footnote on page 22 that
  states "the total value of the Fund's securities on loan is $74,139,994"
  refers to the common stock securities in the Balanced Fund.  In the next
  applicable filing we will clarify which of the Fund's securities each
  footnote refers to.

Comment 4:
  When was the liquidation of Cornerstone Fund completed?  Were there any
  shareholders of Cornerstone at 12/31/2007?

Response 4:
  The liquidation of the Cornerstone Stock Fund was completed on
  March 29, 2007.  There were no shareholders in the Cornerstone Stock Fund
  at 12/31/07.

Comment 5:
  Note 3 to the financials describes the investment of the cash collateral
  received from the lending of securities.  You say there that the collateral
  was "pooled and invested in the following:" and then list a bunch of
  investments.  Do the Funds have an exemptive order under Section 17 of the
  1940 Act to permit this kind of "joint transaction?"

Response 5:
  The footnote referring to the cash collateral as "pooled" will be omitted
  in the future.  The cash collateral received in connection with securities
  lending is invested in a Credit Suisse Separately Managed Account owned
  proportionately by each of the funds.  This separately managed account is
  comprised of the securities listed in the footnote.

Comment 6:
  The Fund's website is out of date.  There is no current prospectus on it.
  How do we know that investors are receiving (have received) a current
  prospectus before they invest?

Response 6:
  Advance Capital's website has been updated and now displays the current
  financial reports and prospectus.  We provide a prospectus to all new
  clients in paper form prior to their initial investment into any Advance
  Capital I, Inc. fund.

Comment 7:
  The chart on the website under the "Mutual Funds" button/link must make it
  clear what is being shown.  It appears to be a daily NAV report for each
  fund, but we need to say that and make sure it is updated daily.

Response 7:
  The chart description on our website has been updated to make it clear what
  is being displayed.  The description now states:

   "DAILY NET ASSET VALUE ('NAV') OF EACH FUND, UPDATED EACH
    BUSINESS DAY THAT THE NEW YORK STOCK EXCHANGE ('NYSE') IS OPEN,
    AFTER THE CLOSE OF TRADING (GENERALLY 4PM EST).  THE NAV IS NOT
    CALCULATED ON DAYS WHEN THE NYSE IS CLOSED."

Comment 8:
  The August 2007 "sticker" filed under Rule 497 to describe the changes in
  management fees that were approved at the annual meeting did not include a
  revised "Annual Fund Operating Expenses" table or a revised "Example" table
  showing the 1-year, 3-year, 5-year and 10-year costs.  Is this a material
  omission from the revised Prospectus and if it was should we make a
  rescission offer to everyone who bought shares from August 4, 2007 until
  April 30, 2008, when the correct tables were put into the prospectus?

Response 8:
  We view this as not a material omission from the revised prospectus.  We
  knew that the management fees approved at the Annual Meeting would marginally
  increase the annual operating expenses for two of the funds.  We decided that
  a restatement of the Annual Fund Operating Expenses table or the Example
  table showing 1-year, 3-year, 5-year and 10-year costs would add more
  confusion to the stickered prospectus than change any of the data in a
  meaningful fashion.  We wanted to highlight the change in management fees
  and not get prospective investors lost in the tables that only show an
  immaterial change in expenses for two funds.  At the time of the approval
  we did not know for sure whether the change in expense ratios would be 1
  or 2 basis points, which easily might have been offset by a 1 basis point
  reduction in other operating expenses for the year.
