Notes on how to engage with our impact estimates
2
This workbook contains impact estimates for grants made or recommended by GiveWell to top charities from 2020 onwards. This workbook does not include impact estimates for funding directed to other charitable programs by GiveWell and therefore represents a conservative estimate of GiveWell's total impact in 2020-2022.

Grants by funding opportunityThis tab lists the cost-effectiveness and estimated impact of specific funding opportunities we've granted to. This is the level at which we do our cost-effectiveness analysis — other tabs (2021 Summary, 2020 Summary) summarize based on the data in this tab. This list of grants constitutes the majority of funding we've directed to top charities since 2020 but is not fully inclusive. We exclude funding that would be especially difficult to attribute to specific funding opportunities, such as donations given directly to our top charities by individual donors following our recommendations.
