Yet with the help of a calculator, I learned how to multiply that positive experience manifold! Imagine that when you give five dollars, you don’t give just to one person, but to seven people. When you reach into your pocket, you see seven smiles. When you put the money in the hat, you hear seven people say “Thank you so much.”

The Life You Can Save has an Impact Calculator that helps you calculate the impact of your giving. You can put in any amount of money you want, then click on a charity of your choice, and see how much of an impact your money can have.

When I learned about this calculator, I decided to check out how far $5 can take me. I went through various charities listed there and saw the positive difference that my money can make.

I was especially struck by one charity, GiveDirectly is a nonprofit that enables you to give directly to people in East Africa. When I put in $5, I saw that what GiveDirectly does is transfers that money directly to poor people who live on an average of $.65 per day. You certainly can’t buy a McDonald’s meal for that, but $.65 goes far in East Africa.

That really struck me. I realized I can get a really high benefit from giving directly to people in the developing world, much more than I would from giving to one person in the street here in the US. I don’t see those seven people in front of me and thus don’t pay attention to the impact I can have on them, a thinking error called attentional bias. Yet if I keep in mind this thinking error, I can solve what is known as the “drowning child problem” in charitable giving, namely not intuitively valuing the children who are drowning out of my sight. If I keep in my mind that there are poor people in the developing world, just like the poor person I see on the street in front of me, I can remember that my generosity can make a very high impact, much more impact per dollar than in the US, in developing countries through my direct giving.

GiveDirectly bridges that gap between me and the poor people across the globe. This organization locates poor people who can benefit most from cash transfers, enrolls them in its program, and then provides each household with about a thousand dollars to spend as it wishes. The large size of this cash transfer results in a much bigger impact than a small donation. Moreover, since the cash transfer is unconditional, the poor person can have true dignity and spend it on whatever most benefits them.

Helida, for example, used the cash transfer she got to build a new house. You wouldn’t intuitively think that was most useful thing for her to do, would you? But this is what she needed most. She was happy that as a result of the cash transfer “I have a metal roof over my head and I can safely store my farm produce without worries.” She is now much more empowered to take care of herself and her large family.

What a wonderful outcome of GiveDirectly’s work! Can you imagine building a new house in the United States on a thousand dollars? Well, this is why your direct donations go a lot further in East Africa.

With GiveDirectly, you can be much more confident about the outcome of your generosity. I know that when I give to a homeless person, a part of me always wonders whether he will spend the money on a bottle of cheap vodka. This is why I really appreciate that GiveDirectly keeps in touch and follows up with the people enrolled in its programs. They are scrupulous about sharing the consequences of their giving, so you know what you are getting by your generous gifts.

GiveDirectly is back by rigorous evidence. They conduct multiple randomized control studies of their impact, a gold standard of evidence. The research shows that cash transfer recipients have much better health and lives as a result of the transfer, much more than most types of anti-poverty interventions. Its evidence-based approach is why GiveDirectly is highly endorsed by well-respected charity evaluators such as GiveWell and The Life You Can Save, which are part of the Effective Altruist movement that strives to figure out the best research-informed means to do the most good per dollar.

So next time you pass someone begging on the street, think about GiveDirectly, since you can get seven times as much impact, for your emotional self and for the world as a whole. What I do myself is each time I choose to give to a homeless person, I set aside the same amount of money to donate through GiveDirectly. That way, I get to see the smile and hear the “thank you” in person, and also know that I can make a much more impactful gift as well.

Check out the Impact Calculator for yourself to see the kind of charities available there and learn about the impact you can make. Perhaps direct giving is not to your taste, but there are over a dozen other options for you to choose from. Whatever you choose, aim to multiply your generosity to achieve your giving goals!
