The retention rate your board sees probably isn't the one that matters

The Fundraising Effectiveness Project puts sector-wide donor retention at around 43–45%. Most boards treat that as the benchmark. You're above it, things are fine. You're below it, there's a problem.

What that number doesn't tell you is which donors you're retaining.

That distinction matters more than most organizations realize — and most organizations aren't making it.

Retention rates get reported as one figure: the percentage of donors who gave again within 12 months. That number can hold steady, or even improve, while the underlying picture shifts in ways that will absolutely show up in your revenue — just not yet.

If you're retaining high-frequency small donors but losing mid-level donors, your rate looks fine and your revenue trajectory is quietly declining. If you're doing better on first-time donor retention but losing your multi-year donors — the ones who typically upgrade over time — you're losing the part of your file that generates disproportionate lifetime value. The headline rate doesn't show you any of that. It just says people came back.

The headline rate is a blunt instrument. It's useful for a board report. It's not useful for making decisions.

Before you report it as a measure of organizational health, a few questions worth asking:

Is your retention rate calculated on unique donors or on gifts? These produce different results, especially for monthly givers.

Does it include lapsed donors who reactivated, or only consecutive-year donors?

How do you handle someone who gives to three different campaigns in the same fiscal year?

Is it segmented at all — by giving level, by acquisition channel, by number of years as a donor — or is it a whole-file average?

None of that is a gotcha. It's just the information you'd need to actually act on the number instead of just reporting it.

Organizations that improve retention consistently over time tend to measure it in segments and hold their definition constant year over year. The consistency is what lets you see a trend instead of just a snapshot. If the way you calculate retention has changed in the last three years — even for a good reason — you're essentially starting your trend line over.

If you've ever presented a retention rate and then couldn't fully explain what was driving it, that's usually why. The number was answering a different question than the one you thought you were asking.

Understanding exactly what your retention rate is measuring — and where the gaps are in what it's telling you — is one of the first things the Revenue Volatility Risk Assessment surfaces. DM me with your questions.
