  • “When I started giving to effective charities, I struggled because I didn’t want to give less to my favourite organizations. Giving Multiplier is a platform that solves this problem by directing some of your giving to effective charities and adding matching funds in order to maximize the collective impact of our charitable gifts!”

    José González

    award-winning singer/songwriter

  • “Want to feel good about making a positive impact? Giving Multiplier is a scientifically-backed innovation that allows you to support causes close to your heart AND some of the world’s most cost-effective charities!”

    Laurie Santos

    Professor of Psychology, Yale University
    and host of The Happiness Lab podcast

  • “Is there a special charity you want to give to because you have a personal connection, but at the same time you know that, dollar-for-dollar, it won’t do nearly as much good as other charities you could give to? Amazingly, you can do both, and still not give less to the most effective charity you can find! Check out Giving Multiplier!”

    Peter Singer

    Professor of Bioethics, Princeton University
    and author of The Life You Can Save

  • “Giving Multiplier is a brilliant tool for anyone who believes in doing good effectively but doesn’t want to abandon their personal connection to specific causes. It helps you do what is simultaneously meaningful to you and highly impactful.”

Frequently asked questions

Giving Multiplier is an award-winning donation platform founded in 2020 by academic researchers at Harvard University with the mission of making charitable giving as impactful as possible. We've helped thousands of donors resolve the "heart vs. head" dilemma in charitable giving: the tension between supporting causes personally meaningful to you and super-effective charities as identified by leading experts. To do so, we add matching funds when donors split their donations between a favorite charity and one of our expert-recommended, high-impact charities. We do not charge fees.

Yes, donations are tax-deductible in the U.S. to the fullest extent allowed by law. After donating, you will receive an email with a receipt from our partner Every.org (EIN: 61-1913297). While donations are currently only tax-deductible in the U.S., you can donate from anywhere in the world.

The email confirmation from Giving Multiplier is NOT a tax receipt. Instead, please make sure to use the email you receive from Every.org. For tax purposes, the nonprofit is Every.org (rather than the specific charities to which you donated).

No, we do not charge fees. This means 100% of your donation will go to charity (minus standard transaction costs for some payment methods). Donations via bank, stock, and DAFs do not have transaction costs (learn more).

Giving Multiplier's operations are funded separately by previous grants from EA Funds, Founders Pledge, and gifts from individual donors.

Because we are not charity evaluators, we rely on the expert research of GiveWell, Animal Charity Evaluators, and Founders Pledge. Our selected recommended charities cover three broad areas: 1) global health and poverty alleviation, 2) animal welfare, and 3) global catastrophic risk reduction.

We do not claim that our selected recommended charities are the only highly effective charities in the world. The selection of recommended charities is our attempt to present you with a small portfolio of charities that are considered highly effective in terms of the amount of good achieved with additional funding based on the best available evidence. We review our selections annually based on the latest expert evaluations. Learn more

Matching funds are provided entirely by individual donors. Thousands of generous donors have donated to our matching fund, which encourages others to use Giving Multiplier to increase their charitable impact.
