How to Research a Charity's Overhead Before You Donate
Calculate the program ratio from Form 990, then check spending limits and fundraising efficiency.
To research a charity's overhead before you donate, pull its recent IRS Form 990 and divide program-service expenses by total expenses. Then compare that program ratio with the 65% program-spending benchmark and the charity's fundraising-efficiency record. Overhead means the share spent on management and fundraising rather than programs.
Form 990 Part IX requires charities to split every expense into program services, management and general, and fundraising, which makes the math comparable across groups.

Get the Form 990 and do the math
Ask the charity for its three most recent Forms 990 or find them through a nonprofit database. The IRS requires U.S. tax-exempt nonprofits to make those three filings public.
Open Part IX and note program-service expenses and total expenses. Divide the first number by the second to get the program ratio. A charity spending $650,000 on programs out of $1,000,000 total has a 65% ratio.
The calculation comes from the expense categories described in a February 2026 BBB Wise Giving Alliance review. Use the same filing year for both numbers. Do not mix audited statements with tax filings in one ratio.
Compare the result with two spending limits
BBB Wise Giving Alliance Standard 8 asks accredited charities to spend at least 65% of total expenses on program activities. The balance covers administration and fundraising. The same standards limit fundraising costs to no more than 35% of related contributions, as explained in the BBB standards for charity accountability.
A charity can pass the program test yet spend heavily to raise each dollar. Check both figures when:
- program ratio is near 65%
- donations come mainly from paid solicitation
- mail, phone, or online ads drive the appeal
Why overhead alone can mislead
Overhead pays for training, planning, evaluation, and systems that support services. GuideStar, Charity Navigator, and BBB Wise Giving Alliance jointly declared on June 17, 2013 that the overhead ratio is "a poor measure of a charity's performance," as reported in their joint announcement on overhead. That joint effort urged donors to weigh transparency, governance, leadership, and results instead.
Economist Jonathan Meer's IZA World of Labor research likewise finds that overhead ratios reflect average rather than marginal costs. His work warns that pressure to keep overhead low can leave charities short on staff and infrastructure, reducing effectiveness.
Check accountability, efficiency, and filing dates
Charity Navigator rates charities on Accountability and Finance plus other beacons, using filed Forms 990 and charity websites. Its method includes fundraising efficiency, or the cost to raise $1, rather than overhead alone. Then check how fresh the numbers are.
Candid warns that the latest online Form 990 often lags the fiscal year-end by 12 to 18 months. Charities under $50,000 in gross receipts may file only a short 990-N e-Postcard, which lacks expense detail. When detail is thin, look for audited financials, board independence, a conflict-of-interest policy, and clear program results on the charity's site.
Give more weight to recent, complete filings than to older summaries.
