For comparison, in 2019, GiveWell estimated that its most cost-effective charity spends $592 per life saved equivalent. (These figures are adjusted for inflation.)
I think you said in 2020 the $592 number was a mistake:
Correction: I copy/pasted the cost per life saved numbers from the previous question, but the $592 number for 2019 is as of the middle of the year. The end-of-year estimate (adjusted to 2015 dollars) is $436.
I think you said in 2020 the $592 number was a mistake:
$436 is a lot closer to $430 than $592.
