Donor Retention: How to Keep the Donors You Already Have

Most nonprofits don't have a donor problem. They have a retention problem. They work hard to find new donors, then lose most of them before the second gift.

When I joined World Concern, only about 6 percent of new donors gave again the following year. We didn't fix that with a better appeal. We fixed it with what happened after the first gift: phone calls to new donors, welcome letters and welcome kits for new monthly donors. By the end of the first year, second-year retention had climbed to 22 percent. By the time I left, it was close to 30 percent, and our multi-year donors renewed at 88 percent.

This guide covers how to measure retention, why donors leave and the practical steps that keep them giving.

How to calculate your donor retention rate

Your donor retention rate is the share of last year's donors who gave again this year.

Donor retention rate = donors who gave last year and gave again this year ÷ all donors who gave last year × 100

If 1,000 people gave last year and 430 of them gave again this year, your retention rate is 43 percent. That's close to the sector average: the Fundraising Effectiveness Project reported overall donor retention of about 43 percent for 2025.

Calculate it three ways, because the averages hide the story:

• First-time donors. People whose first gift was last year. This is usually your weakest number and your biggest opportunity.
• Repeat donors. People who had given at least twice before. These donors renew at much higher rates.
• Monthly donors. Track them separately, and watch failed payments as closely as cancellations.

To see what retention is worth in dollars, look at donor lifetime value.

Why donors stop giving

Donors rarely leave because they stopped caring. More often, they never heard what their gift did, they felt like a number or they only heard from you when you wanted money. Here's a closer look at why donors stop giving.

I see it as a donor too. When I make small gifts, it's common for the experience to end with a transactional receipt. Sometimes I land on an appeal list. Actually hearing someone say thank you is surprisingly rare. A receipt is not stewardship.

Thank donors quickly and personally

The fastest way to improve retention is to thank every donor quickly, and to make at least some of those thank-yous personal. Here's the 48-hour follow-up rule and how one simple change transformed a nonprofit's retention.

I send a lot of handwritten thank-you cards. On a recent trip to the post office, I asked for five rolls of stamps, and the clerk recognized me as the person who always buys them out. A handwritten note from an organization's leader takes time, and that's exactly why donors notice it.

Welcome first-time donors

A first-time donor is deciding whether that gift was a one-time event or the start of something. Plan the first 90 days: a quick thank-you, a welcome message, a story about what their gift did and an invitation to come closer before you ask again. The First-Year Donor Communications course walks through the whole first year.

The second gift matters. At Serving Orphans Worldwide, we know that roughly 30 percent of our new single-gift donors will give a second gift, and we plan our acquisition spending around that.

Report back on what their gifts did

Donors want to know their gift mattered. Tell them what happened, in specific terms they can picture.

One donor I worked with had a goal of providing clean water for a million people in his lifetime. He didn't measure his giving in dollars. Once we understood that, we started reporting his giving in terms of how many people had received clean water. Listen for the goal behind the gift, then report in those terms. More on following up so donors stay informed and engaged.

Build trust and real relationships

Retention is a relationship, not a campaign. Keep your promises, be transparent when things go wrong and talk with donors, not only at them.

Segment your donors

A first-time $25 donor, a monthly donor and a lapsed major donor need different messages. Start simple: new, active, lapsed, monthly and major. Then tailor the ask and the thank-you to each. Here's how to segment your donors. Mid-level donors deserve their own plan; see how to retain more mid-level donors.

Fix the leaks you don't see

Some donors leave without deciding to. A recurring gift fails because a card expired. A welcome email never sends. A donor writes in and no one answers.

At Food for the Hungry and World Concern, when a sponsor's card failed, a recovery process ran for about 60 days: an email with a link to update the card, then a phone call, a letter and a postcard, stopping as soon as the donor updated it. Many sponsors fixed it after the first email.

At Food for the Hungry, I also tested our systems myself at least once a year. I'd sign up, make a small gift and email the contact address, then report what actually happened. My team joked that every July they'd get a note from me saying something was broken. Do it at least quarterly. The partner test is a good place to start.

Win back lapsed donors

Lapsed donors already know you, so they're often easier to bring back than new donors are to find. When I joined Serving Orphans Worldwide, I sent personal cards to significant donors who had lapsed, thanking them for their past support and introducing myself as the new president. Six figures in giving came back.

Here's how to reactivate lapsed donors, with a four-step formula for the letter.

Make retention a habit

Track retention every quarter, not once a year. Give someone ownership of the first-year donor experience. And treat retention with the same attention you give acquisition, because every donor you keep is one you don't have to replace.
