Donor Retention & Lifetime Value Calculator

Acquiring a donor is expensive; keeping one is where the value compounds. A donor’s lifetime value (LTV) depends on how much they give and how long they keep giving — and retention drives the “how long.” Enter your numbers to estimate donor lifespan and LTV, and see how a modest retention gain pays off. (Average new-donor retention runs low — often in the low 20%s — while repeat-donor retention is far higher; see the Fundraising Effectiveness Project.)

The payoff of better retention

A simple model: expected lifespan = 1 ÷ (1 − retention rate); LTV = average annual gift × lifespan. It ignores upgrades and discounting, so treat it as a directional planning estimate, not a forecast.

The most retainable supporters you’ll ever have

Passive supporters don’t lapse like donors do

Retention is hard because giving takes a decision every time. Good Circles supporters decide once, then a share of their everyday local spending funds you automatically — about 10% of each merchant’s net profit, conservatively ~$72 per active supporter per year (an estimate), recurring and unrestricted, free for your nonprofit. It behaves like a near-100%-retention base alongside your donor program.

FAQ

What is donor lifetime value?

Donor lifetime value (LTV) is the total amount a donor is expected to give over the full course of their relationship with your organization. It depends on how much they give each year and how many years they keep giving.

How is donor lifetime value estimated?

A simple model is: expected giving lifespan equals one divided by (one minus the retention rate), and lifetime value equals the average annual gift times that lifespan. A donor giving $120 a year at 60% retention has an estimated lifespan of 2.5 years and an LTV of about $300.

Why does donor retention matter so much?

Because acquiring a new donor usually costs far more than keeping an existing one, and retained donors give for years and often upgrade. Even a small improvement in retention compounds into a large increase in lifetime value.

What is a typical donor retention rate?

According to the Fundraising Effectiveness Project, overall donor retention has hovered in the mid-40% range, with new-donor retention much lower (often around 20%) and repeat-donor retention much higher. Your own rate is the number that matters for planning.
