Multiply your impact
Give to both your favorite charity and a super-effective charity recommended by experts. We'll add to your donations.
How it works
Select your favorite charity
This can be any charity that you care about.
Select a super-effective charity
You can choose from our list of expert recommendations.
Divide your donation between the two
At least 10% has to go to a super-effective charity.
Why donate with Giving Multiplier?
Our goal is to make charitable giving as effective as possible. We support charities that experts have identified as super effective.
We'll add a small donation on top of yours. The more you give to the super-effective charity, the higher the rate.
Your donations are processed by our trusted partner every.org — a non-profit hub for charitable giving. Your data privacy is ensured.
As a project based at Harvard University, Giving Multiplier has been reviewed by the Harvard internal review board and data safety team.

Giving Multiplier is an award winner of the Reimagine Charitable Giving Challenge that honors "promising concepts in the digital giving space"
"The next time you’re ready to give, make two donations: one to a charity that speaks to your heart and one to a charity that’s expert-certified for extraordinary impact."
"I appreciate Giving Multipliers's incrementalist approach to helping people make more effective charitable giving decisions."
"If even just a quarter of all donors applied this strategy, millions of lives would be saved and improved - without donors having to forsake the charities closest to their hearts."
