Notes on how to engage with our cost-effectiveness analysis
2
This workbook contains our cost-effectiveness analysis. Cost-effectiveness is one factor we use to assess which opportunities are the highest-priority to support. We also consider other factors such as urgency, quality of implementation, and more. If you're a donor who wants to be confident that your gift will have a strong impact, please consider supporting the Top Charities Fund.

See the "Cost-effectiveness by funding gap" sheet for a comparison of the cost-effectiveness of the programs our top charities would use additional funding for, as well as additional notes on how we prioritize them. On the "Moral weights and discount rate" sheet, we've included GiveWell and conventional estimates for a few parameters. If you'd like to see how our results would change based on different inputs for these parameters, you can enter your own values in the "Anyone" column.

Expanding the formula bar at the top of the page (by clicking and dragging the bottom boundary) may make it easier to read the contents of explanatory cells.
