25.00We compare charities on a common metric called wellbeing-adjusted life years (WELLBYs). One WELLBY is equivalent to a 1-point increase on a 0-10 life satisfaction scale for one year.
We use WELLBYs to compare the impact of charities that improve different outcomes, such as health or finances. This is the only approach to charity evaluation that allows us to make apples-to-apples comparisons. No other charity evaluator uses this approach.
