This calculator projects giving from three numbers: how many donors you have, the average gift, and how often they give across a year.
It then models a recurring program. Monthly donors give more reliably and more overall, so even a modest recurring uplift compounds into meaningfully higher annual totals.
Use it to set a fundraising target and to make the case for investing in recurring giving rather than relying on one-off appeals.
Frequently asked questions
Why push recurring giving?
Recurring donors are more predictable and have far higher lifetime value than one-time givers. Converting even a slice of your base to monthly giving stabilizes cash flow across the year.
What uplift is realistic?
Organizations that launch a recurring program commonly see total giving rise 15–30% over time as monthly donors accumulate. Start conservative and adjust as yours grows.
