Key takeaways
- Net revenue retention measures how many dollars this year's file kept from last year's donors, after upgrades, downgrades, and lapse, expressed as a percentage of what that group gave before.
- Headcount retention counts how many donors came back; net revenue retention counts how many of their dollars came back, and the two can move in opposite directions.
- Across the sector in 2025, total dollars rose 5.0% while the number of donors fell 3.6%, a gap that headcount retention alone would miss (Fundraising Effectiveness Project).
- The idea comes from subscription businesses, where net revenue retention above 100% means the existing base grows on its own; the median software company sits roughly between 105% and 110% (analogy, labeled).
- Donor Insights reads your own giving records to compute net revenue retention on any cohort, so you can see whether upgrades are offsetting lapse or a shrinking base is being propped up by a few large gifts.
Net revenue retention asks a sharper question than how many donors came back. It measures how many dollars this year's file kept from last year's donors, after their upgrades, their downgrades, and the ones who lapsed, as a percentage of what that same group gave the year before. A file can lose a lot of donors yet hold most of its dollars if the ones who stayed gave more, and plain headcount retention would never show it. Across the sector in 2025, total dollars rose 5.0%, the strongest growth in five years, while the number of donors fell 3.6%, according to the Fundraising Effectiveness Project, which is exactly the split net revenue retention is built to read.
What is net revenue retention for a nonprofit?
Take one group of donors, the people who gave last year, and follow only that group into this year. Add up what they gave last year. Then add up what the same people gave this year, counting the ones who gave more, the ones who gave less, and the ones who gave nothing. Divide this year's total by last year's. That percentage is your net revenue retention. It folds four things into one number:
- 1.Dollars kept from donors who gave again at the same level.
- 2.Plus upgrades, the extra dollars from donors who gave more.
- 3.Minus downgrades, the dollars lost from donors who gave less.
- 4.Minus lapse, all the dollars from donors who did not give at all.
Note what is left out: new donors. Net revenue retention measures only the base you already had, so it tells you whether that base is holding its value before any acquisition is added on top.
How is it different from donor retention?
Donor retention counts people; net revenue retention counts dollars. You can keep 60% of your donors and still hold 85% of your dollars if the donors who stayed gave more, or keep 60% of your donors and hold only 45% of your dollars if the ones who left were your largest. Headcount retention treats a lapsed $5 donor and a lapsed $5,000 donor as the same loss. Net revenue retention does not. The sector's 2025 split, dollars up 5.0% and donors down 3.6%, is the clearest sign that the two numbers tell different stories, and that reading only the donor count can leave you blind to where the money actually went.
This is why net revenue retention pairs with, rather than replaces, your donor retention rate. One tells you how many people stayed; the other tells you how much of their giving stayed. Read together, they show whether a file is healthy or being carried by a shrinking group of larger donors.
Where does the idea come from, and what does 100% mean?
From subscription businesses, and the analogy is worth borrowing with care. Software companies track net revenue retention on their existing customers, and the line everyone watches is 100%. Above 100% means the base grew on its own, through upgrades outpacing cancellations, before a single new customer was added. Below 100% means the base is shrinking in dollars and only new sales can hide it. The median software company holds roughly 105% to 110% (a for-profit figure, applied here by analogy). Donors are not subscribers, and most nonprofit files sit below 100% because giving is voluntary and lapse is high, but the target is the same: get the dollars you keep from last year's donors as close to, or past, what they gave before.
How do you calculate net revenue retention on a donor file?
Picture a fictional organization, Trailhead Alliance, following the donors who gave last year. The numbers below are illustrative, chosen to show the method rather than to stand as a benchmark. Last year that group gave $100,000. This year, some lapsed, some gave less, and some gave more.
| Line | Dollars |
|---|---|
| Prior-year giving from this cohort | $100,000 |
| Minus dollars lost to lapsed donors | minus $25,000 |
| Minus downgrades from donors who gave less | minus $8,000 |
| Plus upgrades from donors who gave more | plus $15,000 |
| This-year giving from the same cohort | $82,000 |
| Net revenue retention | 82% |
Trailhead kept 82% of its dollars from last year's donors. Suppose it kept only 60% of the donors themselves: the two numbers diverge because upgrades from the donors who stayed offset much of what lapse took away. Read the headcount alone and you would see a 40% loss; read the dollars and the base held far better than that. Had upgrades outrun lapse and downgrades combined, the figure would have crossed 100%, and the file would have grown on its own before adding a single new donor.
Why does net revenue retention tell you more?
Because it captures the two moves headcount retention cannot see: donors who deepen and donors who pull back. A file can look stable in people while its dollars quietly erode as mid-level donors downgrade, or it can look shrinking in people while its dollars grow as loyal donors give more. It also flags fragility that a rising total hides: if net revenue retention is under 100% and only new, larger gifts keep the headline up, the base is thinning under the surface. That is the same warning you get from donor lifetime value, read across the whole file rather than one donor at a time.
“Increasing customer retention rates by 5% increases profits by 25% to 95%.”
The direction holds for giving even though donors are not customers: the dollars you keep from donors you already have move the total more than almost anything you can do to acquisition. The surest way to lift net revenue retention is to keep more donors and help willing ones deepen, which is why a growing recurring giving share matters so much. Recurring donors rarely downgrade and rarely lapse mid-year, so they hold the floor under this number. Donor Insights reads your own giving records and computes net revenue retention on any cohort, so you can see whether upgrades are offsetting lapse or a shrinking base is being propped up by a handful of large gifts.
Frequently asked questions
- What is net revenue retention for a nonprofit?
- It is the share of last year's donor dollars that the same donors gave again this year, after upgrades, downgrades, and lapse. Follow one group of prior-year donors into this year, divide their new total by their old total, and that percentage is your net revenue retention.
- How is it different from donor retention rate?
- Donor retention counts how many donors came back; net revenue retention counts how many of their dollars came back. You can keep 60% of donors and hold 85% of dollars, or keep 60% and hold 45%, depending on whether the donors who stayed gave more or the ones who left were your largest.
- What is a good net revenue retention for a nonprofit?
- There is no published sector benchmark, and most files sit below 100% because giving is voluntary and lapse is high. The useful comparison is your own number over time: rising net revenue retention means the base is holding or deepening, and crossing 100% means it grows before any new donor is added.
- Why borrow the metric from subscription businesses?
- Because software companies built net revenue retention to answer the same question a fundraiser has: is the base I already have growing or shrinking in dollars. The median software company holds roughly 105% to 110% (a for-profit figure by analogy); donors are not subscribers, but the 100% line is a clarifying target.
