This is an exercise in creating maximum leverage for small to medium sized donations and an exercise in showing how just about any citizen in an industrialized country could save at least one life each year in their spare time.

Suggested Prerequisites

  • An annual donation budget or spare time to generate some extra funds. 
    Personally, I’ve used the Uber Driver app to take advantage of the occasional lucrative promotion or peak event demand in a nearby city. Also I'm a US resident, so I can sign up for new plasma donor programs at 1-2 new centers a year that pay an initial $700-$1200 for 8 donations in the 1st month. These centers include places like CSL Plasma, Biolife, Grifols, Biomat, Freedom Plasma, Kedplasma, Immunotek, Gcam Plasma, Octapharma Plasma, and BPL Plasma. 
    People with different resources and skills may have other ways of generating their initial donation funds, but these are just some examples if your current job doesn't include a high income.
  • A credit score of 670 or higher.


First Multiplier: Credit Card Sign-Up Bonuses For Donations (1.1x to 1.65x)

If you have a 670+ good or excellent credit score, then you can qualify for several credit cards with sign-up bonuses ranging from $200 back on the 1st $500 spent to 10% back on several purchases for the 1st year (including some sites where you may make an online donation). All this requires is the good credit score, reading some sign-up bonus conditions to ensure your donation transaction(s) will qualify, and time to fill out the paperwork & unfreeze your credit on your credit site(s) like Experian or Transunion.

In addition, some of these cards offer referral bonuses for people who sign up with your referral link (Ex: https://capital.one/3y2YbGv).

So if you want to coordinate with some of your friends or with other Effective Altruists in the community, then you can use these referral bonuses to multiply your funds even more than the 1.1x to 1.65x listed in the section header.

Second Multiplier: Donation Matching Events (1x to 2x)

***UPDATE: Facebook has significantly changed their donation processes the 2nd year in a row & there is no word yet on if there is donation matching in 2023 or how it would work. I will be holding my funds until Giving Tuesday incase new info comes out. If nothing comes, I will use an alternate set of donation multipliers as described in the rest of this post.***

Here donation matching events mean things like Facebook's Giving Season matching event or Every.org's occasional matching events. These are events where matching funds could go to less effective charities or to more effective organizations like EA charities, so securing these matches for EA charities is not a gimmick and truly adds more funds to EA charities.

There is usually a post about Facebook's giving event on the EA forum each year, for example here is the EA Giving Season instructions post for 2022. This Facebook event seems to be very popular, so there is more EA supporting material on it. However, as listed in the annual posts, there is a limited amount of matching funds for this event. Facebook will ultimately match up to $7,000,000 in donations overall. Each person can donate up to $20,000 for matching & each organization can receive up to $100,000 in matched funds. But Facebook will only match up to $100 of a recurring donation for each organization between November 15 & December 31. So if you set up a recurring donation of $100 for an organization on November 15 after 9AM Pacific Time, then the recurrence donation on December 15 will be matched with $100. So this is effectively a 1.5x donation on each $100. More news and information on past years is listed here.

Other matching events like Every.org's are significantly less competitive, but may come with other limitations like lower donation limits for matching funds. For example there was this past matching event with a $100 donation matching limit.

If you apply for a credit card with a good sign-up bonus a month or two before one of the donation matching events and the sign-up bonus conditions apply to the donation matching site or vendor, then you can use that card for your matched donation(s) to combine the card sign-up bonus multiplier with the donation matching event multiplier.


Third Multiplier: Employer Donation Matching (1.1x to 2x the donation transaction amount)
[*Will likely add to, but not multiply with a donation matching event multiplier]

Some organizations have charitable donation matching programs for their employees. Most employer programs will match 50%-100% of their employees’ donations within certain limits like donation minimums and/or maximums. The employees often just need to check that their donation will qualify under their organization’s policies and submit a donation match request with documentation of their donation transactions. 
If you plan to combine an employer donation match with donation matching events, make sure to check how the event site processes & documents the donation transactions. If the donation is made to the event site or some intermediary, make sure your employer‘s donation matching policies accept donation documentation from such a site or intermediary. For example some organizations will match Facebook donations, while others may not.


Fourth Multiplier: Donate to Giving Multiplier's Matching Fund (1x to 2x)

Giving Multiplier is a site that runs a kind of year-round matching program to encourage people less familiar or less engaged with EA to donate more money to GiveWell charities. The site allows people to bundle a donation to their favorite charity with a donation to an effective GiveWell charity and Giving Multiplier will match the portion of the donation going to the GiveWell charity. Depending on how many people are encouraged to donate more to effective charities, Giving Multiplier could direct anywhere from 1 to 2 times the money sent to their matching fund to effective charities.

By using the sign-up bonus credit cards to donate to Giving Multiplier’s effective charities matching fund & submitting receipts to an employer matching program, you can stack the card cash back multiplier, employer match multiplier, and a Giving Multiplier fund multiplier.

For more on Giving Multiplier, see this update from the founders on the EA forum and this critique from another community member.



[Any plus marks are for the additional employer match of original donation transaction amounts. These do not go through the same donation event multiplier like Facebook‘s Giving Season, so they are additive & not multiplicative.]

Lowest Multiplier Stack Estimate: 1.1Card * 1.5FB = 1.65x

Likely Multiplier Stack Example: 1.25Card * (1.5Employer + 1.5FB) = 3.75x

Highest Multiplier Stack Estimate: 1.65Card  * 2Employer * 2GiveMulti = 6.6x


Even if someone only had $2000 to donate or only 40-60 spare hours to generate the equivalent funds, they could use some method of donation multiplier stacking to direct enough money to effective programs to save at least one life per year.

Some points for why Giving Multiplier could still be pretty good even if more funds are directed to slightly less effective GiveWell charities than things like bed-nets:

  1. As EA starts to move a lot more money each year and potentially gets more push-back for concentrating its power in the non-profit space, Giving Multiplier offers a step in the funding process that allows more non-EAs to voice where they want more of these concentrated funds directed. It gives even outsiders a bit of a democratic voice in our processes.

  2. If these outsider voices seem to tip things towards non-optimal allocations, then GiveWell’s maximum impact fund could still adjust its allocation of funds to the better marginal options. So the more democratic Giving Multiplier funds can just displace other funding sources for lower impact GiveWell charities & those displaced sources can then give to the higher impact GiveWell charities in response.
