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 interested in supporting the top charity we believe will do the most good at the time your donation is granted, please consider supporting the Maximum Impact Fund.

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 make a copy of this spreadsheet and 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.
