The donor retention rate formula and how to calculate it, what a good rate looks like by segment, the five reasons donors lapse, and why the reason has to be captured on the donor record.
Donor retention rate is the share of last year's donors who gave again this year, expressed as a percentage: donors who gave in both years divided by donors who gave last year, times 100. Its complement is donor attrition — the share who lapsed. A rate of 46% means fewer than half of last year's donors returned. The rate names the problem; it does not explain it.
The rate is easy to compute and tells you nothing about why donors left. That is the gap this guide closes: the formula and how to calculate it, what a good donor retention rate looks like by donor group, the five reasons donors stop giving and the retention move for each, and why the reason a donor lapses has to be captured on the donor's record — not guessed after they are gone.
Key takeaways
To calculate donor retention rate, divide the number of donors who gave in both the current and prior year by the number who gave in the prior year, then multiply by 100. Run it per cohort and per giving level, because an organization-wide number averages away the segments that are actually failing.
The most important cut is first-year versus repeat donors: first-year retention is typically around 20–25% and repeat-donor retention 60% or higher, so a single blended figure hides where the base is leaking. The reporting that keeps donors — showing the outcome their gift produced — is on donor impact report.
A good overall donor retention rate is above 50%, against a sector average that sits closer to 45%; first-year retention around 20–25% is normal and the biggest opportunity, while repeat and monthly donors should retain at 60–80% or more. The benchmark that matters is your own rate over time, by segment, not a single industry number.
The reason first-year retention is the lever is arithmetic: turning a one-time gift into a second gift is where most of the loss happens, and a small gain there compounds across every future year. Read the table for what to aim for by group. Where donor data sits alongside program impact is on nonprofit analytics.
| Donor group | Typical rate | What to aim for |
|---|---|---|
| Overall (all donors) | Around 45% | Above 50% is healthy; sector average is low |
| First-year donors | Roughly 20–25% | The biggest leak — small gains compound |
| Repeat / multi-year donors | 60–70%+ | Loyal base; protect it, do not assume it |
| Monthly / recurring | 80%+ | The most durable; grow this segment |
Most donor retention programs are run off the gift record alone: the CRM shows who gave and who lapsed, a quarterly list of lapsed donors is pulled, and a win-back appeal goes to all of them with the same message. The rate goes down and nobody can say why, because the reason each donor left was never captured.
Sopact calls the missing piece The Lapsed-Donor Reason: every gift, survey, and interaction on one donor record, with the open-ended feedback coded on arrival, so the reason a donor is disengaging is known before they lapse and outreach is reason-specific rather than blanket. The difference is a data-model one — a rate computed from gift records versus the reason captured on the same record. This is why donor retention is a stakeholder intelligence problem: the reasons are in feedback you have to collect and read. That practice is on stakeholder intelligence, and reading the open-ended feedback on feedback analytics software. The stage below shows one lapsing donor handled both ways.
Donors lapse for five recurring reasons: they never heard what their gift achieved, they felt solicited rather than stewarded, a more compelling cause appeared, their own circumstances changed, or they were never really retained past the first gift. Each has a specific retention strategy, and none of them is a louder ask.
The strategy that moves the rate most is the first one — closing the feedback loop by reporting the outcome a donor's gift produced — because it addresses the reason donors most often give for leaving. Read the table for the move that matches each reason. Turning donor feedback into a theme you can act on is on survey analysis.
| Why donors lapse | What it signals | The retention move |
|---|---|---|
| They never heard the impact | No feedback loop after the gift | Report the outcome their gift produced |
| They felt like an ATM | Only asked, never thanked or updated | Steward before you solicit again |
| A better cause appeared | Weak emotional connection | Tie giving to a specific, cited result |
| Life or budget changed | Often unavoidable | Offer a smaller or paused option, not silence |
| They were never really retained | First gift never became a second | Fix the second-gift conversion, not just win-back |
A retention program that acts on a quarterly lapsed-donor list is always too late — the donor has already gone. Reading donor feedback as it arrives catches a disengaging donor while they are still giving. That is the premise of the Loop, Sopact's method for continuous impact intelligence: collect clean at the source, analyze the moment data arrives, improve while you can still act.
The Loop is also what makes a retention claim defensible. Every reason and sentiment traces to the donor and the response behind it, so a retention decision resolves to real feedback rather than a guess. That standard has its own chapter in reliability and reproducibility. Where donor data connects to program impact is on impact reporting.

The fastest way to move the rate is to read the feedback you already have for the reasons donors are disengaging. Each prompt below pastes into Sopact Sense's Assistant, or reasons through with your team; the arrow above each links the Academy walkthrough that shows the expected output and the tips.
Academy walkthrough → Find who is disengaging and why
From this donor feedback and giving data, find the donors most likely to lapse and why: [PASTE FEEDBACK + GIFT HISTORY]. Score disengagement from sentiment and giving signals, name the dominant reason per at-risk segment, and give two verbatims each. Return a table: Donor segment / Disengagement signal / Dominant reason / Verbatims / Suggested move.
Academy walkthrough → Code the lapse reasons
Code these lapsed-donor responses against the five common reasons — no impact reported, felt like an ATM, better cause, circumstances changed, never retained: [PASTE RESPONSES]. Return the distribution across the five reasons, three verbatims per reason, and anything that does not fit marked OTHER. Do not force a response into a reason it does not support.
Academy walkthrough → Calculate retention by segment
Calculate donor retention and attrition from this gift data, by segment: [PASTE GIFTS BY DONOR AND YEAR]. Report the overall rate and the rate for first-year, repeat, and recurring donors, with the formula shown. Flag the segment leaking most. Return a table: Segment / Retained / Lapsed / Rate / Formula.
Academy walkthrough → Design the impact a donor sees
Design the outcome report a donor should receive after giving, to close the feedback loop: [PASTE PROGRAM + GIFT TYPES]. For each gift level, name the specific outcome the gift contributed to and the evidence behind it. Avoid vague impact language — tie each to a cited result. Return a table: Gift level / Outcome shown / Evidence.
Each walkthrough is a hands-on companion written to run on your own data: what to do, the prompt to run, the output to expect, and the tips that keep it reliable.
Watch: reading donor feedback on one record so the reason a donor is about to lapse is known in time to keep them — not guessed after they are gone.
Donor retention rate is the percentage of last year's donors who gave again this year: donors who gave in both years divided by donors who gave last year, times 100. Its complement is donor attrition, the share who lapsed. The rate names the problem but does not explain it. Sopact's framing is the Lapsed-Donor Reason — the reason a donor leaves has to be captured on the donor record, not guessed once they are gone.
Divide the number of donors who gave in both the current and prior year by the number who gave in the prior year, then multiply by 100. For example, if 500 donors gave last year and 230 of them gave again, the retention rate is 230 ÷ 500 × 100 = 46%. Calculate it per cohort and per giving level, because an organization-wide figure averages away the segments that are actually failing. Sopact keeps gift and feedback data on one record so the rate is a query, not a merge.
The formula is: retention rate = (donors who gave this year and last year) ÷ (donors who gave last year) × 100. Attrition rate is 100 minus the retention rate. The formula is simple; the value comes from segmenting it — first-year versus repeat versus recurring donors — and from pairing it with the reason donors lapse, which the formula itself cannot tell you.
A good overall donor retention rate is above 50%, against a sector average around 45%. First-year donor retention of 20–25% is normal and is the biggest opportunity, while repeat donors should retain at 60% or more and monthly donors at 80% or more. The benchmark that matters most is your own rate over time by segment, not a single industry number. Sopact's point is that improving the first-year rate compounds across every future year.
Because retention compounds: a donor kept this year is more likely to give next year and the year after, so a small lift raises the lifetime value of the entire donor base for years, not just once. It is almost always cheaper to keep a donor than to acquire a new one. Sopact's contribution is catching disengaging donors early, from their feedback, which is where the compounding gain is won.
Five recur: they never heard what their gift achieved, they felt solicited rather than stewarded, a more compelling cause appeared, their own circumstances changed, or they were never really retained past a first gift. The most common and most fixable is the first — no impact reported back. Sopact codes lapsed-donor feedback against these reasons so the retention strategy matches the actual cause instead of defaulting to a louder ask.
Close the feedback loop by reporting the specific outcome a donor's gift produced, steward before you solicit again, offer a smaller or paused option instead of silence when circumstances change, and fix second-gift conversion for first-year donors. Underneath all of them is knowing why each donor is disengaging, from their own feedback, in time to act. Sopact holds that reason on the donor record so outreach is reason-specific rather than a blanket win-back.
Donor attrition is the complement of retention — the percentage of last year's donors who did not give again. If retention is 46%, attrition is 54%. Attrition is highest among first-year donors, which is why first-gift-to-second-gift conversion is the biggest lever. Sopact treats attrition as a signal to read rather than a number to report: the reason behind each lapse, captured on the donor record, is what makes it reducible.
Next: close the feedback loop on donor impact report, or treat retention as listening on stakeholder intelligence.
