The Impact Audit

Providing donors the analysis needed to make smart, informed funding decisions.

Standard for Analyzing Impact

Our impact audit standard answers key questions a smart funder asks before supporting a nonprofit.

Impact and Cost
Impact÷Cost=Benefit/Cost Ratio

How much impact does your dollar buy? We report the best available estimates of average cost and impact on outcomes, giving the donor perspective on what a donation to the organization could achieve.

Quality of Evidence
Estimates are based on data collected internally and evidence from elsewhere

Quality of Impact Evidence captures how confident we are that the nonprofit’s program is leading to impact on its primary outcomes. Nonprofits with high-quality evidence of impact are delivering an intervention that has been shown to work.

What about financial metrics, such as a nonprofit's overhead ratio? Read why these are misleading
