From at least as early as December 2023 (possibly as early as December 2021 when the page says it was first published) until February 2024, that page highlighted a $7.2 million 2020 grant to the Against Malaria Foundation at an estimated cost per life saved of $4,500.
The page now highlights a $6.4 million 2023 grant to the Malaria Consortium at an estimated cost per life saved of $3,000.
You can see all the estimated cost per life saved (or other relevant outcome) for all GiveWell’s grants at this spreadsheet, linked-to from:
I wonder how they select grants to showcase on that page. They’ve made grants that are both much larger and more cost-effective than that, e.g. this $71.5M grant in Jan ’23 to HKI’s vitamin A supplementation program that they estimate would save roughly 49,000 lives at ~$1,450 per life saved after all adjustments (or ~93,000 lives at $770 per life if only adjusting for internal and external validity, or nearly 280k lives at at $260 per life saved before any adjustments, i.e. the standard I usually see in most BOTECs claiming to “beat GW top charities”...). Only thing is, this wouldn’t be obvious from their original CEA because they tend to input “donation (arbitrary size)” = $100k instead of the actual grant amounts; I had to manually input their grant budget breakdown into a copy of their CEA to get the numbers above (which also means I may have done it wrong, so caveat utilitor...)
GiveWell’s cost to save a life has gone from $4,500 to a range between $3,000 and $5,500:

I would guess that it’s based on the marginal grant, but of course someone at GiveWell should be able to confirm.
