Most monthly-giving targets are picked out of thin air: a round number that sounds ambitious in a board meeting. The organizations that actually hit their number start from the math instead, and the math is simpler than most development teams assume once you have three inputs in front of you.
Why round-number targets fail
A target like “let’s get to 500 monthly donors this year” feels motivating in a board meeting, but it has no relationship to your list size, your typical conversion rate, or your average gift, which means it’s equally likely to be wildly conservative or wildly unrealistic, and no one finds out which until months later. Worse, a missed round-number target reads as a program failure to a board, even when the underlying program is actually performing well against a more honest baseline.
The formula we start with
Take your active donor list size, multiply by a realistic monthly-conversion rate (2–4% for a first push, higher once the program matures), then multiply by your average monthly gift amount. That’s your honest year-one target, not the number you wish were true, but the number your actual list and actual conversion rate can support.
For example, a list of 4,000 active donors converting at 3% with an average $25 monthly gift produces roughly 120 new monthly donors and $3,000 in new recurring monthly revenue in year one: a number that sounds far less dramatic than “500 donors” but is one your team can actually hit and build credibility on.
“A monthly-giving program is a compounding asset. Year one is never the impressive year.”
Where the real growth comes from
- Converting one-time year-end donors into monthly gifts the following January, when their last gift is still fresh and a lower monthly amount feels like an easy next step.
- A dedicated ask embedded in every campaign, not just a footer link, so monthly giving is presented as a real option rather than an afterthought.
- Retention: monthly donors who stay past 12 months rarely cancel after that, which means the program compounds year over year far more than one-time giving ever does.
This is why year one always looks modest compared to year three: the list of active monthly donors keeps growing while cancellations stay low, so the same conversion effort produces a larger base every year it runs.
This is the kind of program our fundraising campaigns team plans and runs for clients.
Reporting monthly giving to your board
Report two numbers side by side: new monthly donors acquired this period, and total active monthly revenue run-rate. The first shows whether acquisition is working; the second shows the compounding asset actually building over time, which is usually the more persuasive number in a board meeting because it demonstrates the program’s value is growing even in a month with modest new signups.
A simple 90-day plan to launch or grow the program
Run the formula above to set an honest target, then spend the first 30 days building or refreshing a dedicated monthly-giving ask on your donation page and in your next campaign. The next 30 days should focus on a targeted conversion push to donors who gave a one-time gift in the last 12 months, since they convert at a far higher rate than cold traffic. The final 30 days are for measuring what actually happened against your target and adjusting the conversion rate assumption for next quarter’s plan, rather than guessing again from scratch.
