Donor stewardship: keeping the donors you already have

This guide is for whoever looks after donors at a small charity: the founder, a board member, the volunteer who keeps the donor list. Stewardship means everything you do after a gift arrives: thanking, reporting back, staying in touch, so that a donor feels part of the work and chooses to give again. After reading, you'll be able to thank donors quickly, show them what their money did, plan a simple year of contact, look after monthly and lapsed donors, and work out your own retention rate.

If you're still finding your first donors, start with building a donor base. This guide picks up from the first gift.

Why keeping donors matters

Many charities lose more than half their donors from one year to the next. The Fundraising Effectiveness Project (FEP), which tracks giving data from about 15,000 US nonprofits, found that overall donor retention was 43.3% in 2025, up slightly from 43.1% the year before. In other words, most donors who gave in 2024 didn't give again in 2025. The same report estimates that the number of donors fell 3.6% in 2025.

Every donor you keep is one you don't have to replace. Good stewardship is how small charities beat those averages.

Thank donors within days

A fast, personal thank-you is the most important stewardship habit.

• Aim for a few days, not weeks. Set a rule, such as every gift thanked within 48 hours, and stick to it.
• Make it personal. Use the donor's name, mention the amount or what it's for, and sign it yourself. A short handwritten note or a phone call from a board member stands out.
• Say what the gift will do, in concrete terms: "Your $50 buys a week of groceries for a family of four" only if that's true for your program.
• Thank first-time donors twice. A quick thank-you, then a short welcome a few weeks later that tells them more about your work.

The thank-you letter can also be the tax receipt. The IRS says a donor needs a written acknowledgment from you for any single gift of $250 or more, with specific contents. Our guide to thanking donors the way the IRS requires explains the rules, and our donor thank-you letter template has ready-made wording.

Show donors what their gifts did

Donors give to make something happen. Tell them it did.

• Send short updates a few times a year: one story, one photo (with permission) and one number, like meals served or students tutored.
• Report on what they funded. If a donor gave for a specific project, tell them how it went, including what didn't work and what you learned.
• Send a yearly summary. A one- or two-page report on the year is enough. Our annual report guide shows how.
• Use real results. Our measuring impact guide helps you track a few honest numbers you can share.

A yearly stewardship calendar

Put stewardship on the calendar so it happens even in a busy year. A simple plan:

Adjust it to your size. A charity with 40 donors can call each one. A charity with 4,000 might call the top 100 and send the rest a personal-sounding email.

Recurring donors

Monthly donors are often your most valuable supporters, because their gifts keep coming without a new ask each time.

• Thank them when they sign up, and again at least once a year with a summary of what their monthly gift added up to.
• Keep them close. Send them the same updates as other donors, and sometimes something just for them.
• Watch for failed payments. Cards expire. When a payment fails, contact the donor quickly and kindly; most will happily update their card.
• Make changes easy. Tell donors how to change or pause their gift. A donor who can pause is less likely to cancel.

Lapsed donors

A lapsed donor is someone who gave before but hasn't given in the last year or so. Most weren't unhappy; often nobody asked them again or they forgot.

• Find them. Once a year, list everyone who gave last year but not this year.
• Reach out personally. A short note or call: "We've missed you, and here's what's happened since your last gift."
• Ask, gently. Invite them to give again, with a clear, specific reason.
• Respect their choice. If someone asks to stop hearing from you, take them off the list and record why, if they tell you.

A simple donor database makes this much easier. Our guide to choosing a donor database compares options for small charities.

Work out your retention rate

Your donor retention rate is the share of last year's donors who gave again this year. To work it out:

1. Count the donors who gave last year. Call this A.
2. Of those, count how many gave again this year. Call this B.
3. Divide B by A and multiply by 100.

Retention rate = (donors who gave last year and again this year ÷ all donors who gave last year) × 100

For example, if 80 people gave last year and 36 of them gave again this year, your retention rate is 36 ÷ 80 × 100 = 45%.

Count each donor once, however many gifts they made. Work out the rate for first-time donors separately too: they're usually the hardest to keep, and the first thank-you matters most for them. Compare your rate with your own past years first. A rising rate means your stewardship is working.

Your stewardship checklist

• Every gift is thanked personally within a few days
• Donors of $250 or more get a written acknowledgment that meets IRS rules
• First-time donors get a welcome note a few weeks after their gift
• We send at least three updates a year that don't ask for money
• We have a yearly stewardship calendar and someone owns it
• Monthly donors get a yearly summary, and failed payments are followed up quickly
• Once a year we list lapsed donors and contact them personally
• We work out our retention rate every year and compare it with last year
