A first gift tells you somebody responded. A second gift tells you they meant it. Second-gift conversion is the most honest measure of a stewardship programme, because it isolates the part you actually control.
Most fundraising reporting treats a donor as acquired the moment the first gift clears. The data does not agree. A first gift tells you somebody responded to something. A second gift tells you they meant it.
First gifts are driven by the ask: the appeal that landed, the event they attended, the friend who asked. Second gifts are driven by what happened afterwards. Whether the thank-you arrived, whether it said anything, whether the organisation behaved as though the gift mattered.
That is why second-gift conversion is the most honest measure of a stewardship programme. It isolates the part you control.
Take everyone whose first gift fell in a given quarter. Count how many gave again within twelve months. That is your conversion rate for that cohort. Run it by quarter and you have a trend line that most organisations have never seen.
The number itself matters less than its direction, because definitions vary and benchmarks travel badly between organisations. What matters is whether your own figure is moving, and what you changed when it did.
The thank-you is a receipt. A receipt confirms a transaction. It does not give anyone a reason to do it again.
The second ask is the same as the first. The donor has already told you something by giving. Asking identically ignores it.
Nobody owns the window. The first ninety days after a first gift are usually unowned by anyone in the organisation, which means they are unmanaged.
Pick one cohort and treat the ninety days after the first gift as a deliberate sequence rather than a gap. Then measure the next cohort against it. This is one of the few fundraising changes that costs nothing, needs no new software, and shows up in the numbers within a year.
Boards find this measure useful because it separates the work of acquisition from the work of keeping people. Those are different problems with different fixes, and a single retention figure hides both.
Most of these started as a question somebody asked on a call.
