How we analyze nonprofits

We rate nonprofits based on their cost-effectiveness using a combination of nonprofit data and social science. We believe strongly in transparency. If you want to dive into our methods, start with our Impact Rating Standard.

Rating Process Read More

Step 1
Data search

We search websites, GuideStar and other public databases for a set of data points needed to calculate impact, such as the number of meals served.

Step 2

For each type of program — soup kitchen, scholarships, etc. — we build an equation to calculate impact. This equation combines data from the nonprofit (e.g., number of scholarships awarded) with social science research (e.g., effect of a scholarship on future earnings). We calculate the equation for each nonprofit.

Step 3

We then issue a star rating. To do so, we compare the nonprofit’s impact to common benchmarks. If a nonprofit is significantly better than the benchmark, we determine it is highly cost-effective and assign 5 stars. A high rating indicates that the nonprofit is making good use of resources to improve the lives of the people it serves.

Rating is a complex and inherently imperfect exercise and we urge you to read our frequently asked questions and Impact Rating Standard for details of how and why we issue these ratings.
