How your CC/ACH payment mix affects involuntary churn and 5-year recurring donor LTV. Shifting donors to ACH/EFT reduces involuntary churn from ~13% to ~2% annually.
Donor lifetime value (LTV) is the total net revenue a donor generates over their entire relationship with your organization. It is the single most important metric for evaluating fundraising channel performance, setting acquisition budgets, and making strategic investment decisions. Without understanding LTV, you are flying blind on the most consequential financial decisions your development team makes.
LTV forces you to think beyond the first gift. A $75 single gift looks fine in isolation — but when you calculate the lifetime revenue stream accounting for retention, upgrade behavior, and giving frequency, the picture changes dramatically. A recurring donor giving $25/month typically delivers 3-8x the lifetime value of a single-gift donor, even when the recurring donor costs more to acquire. Understanding this gap is fundamental to building an effective donor retention strategy.
For a deeper framework on applying LTV to your fundraising strategy, see our donor lifetime value strategy guide. And if you need the fundraising systems infrastructure to actually track and act on these metrics, we can help with that too.
This calculator gives you the data to make three critical decisions:
The defaults in this calculator are sourced from widely-cited sector benchmarks:
Your organization's actual rates will vary. We encourage you to pull your real data from your CRM and plug it in. If you need help benchmarking your retention rates, our fundraising operations audit includes a full retention analysis.
The most powerful insight from this calculator is how retention improvements compound. A 5 percentage point improvement in retention does not create a 5% increase in LTV — it creates a 15-25% increase at 5 years and a 30-50% increase at 10 years. This is because each year's retained donors carry forward into every future year.
This compounding effect means that retention is almost always a higher-ROI investment than acquisition. Yet most organizations spend 90%+ of their fundraising budget on acquisition and under 10% on retention. If this calculator reveals a large gap in your program, our donor retention consulting practice can help you close it.
For recurring donors specifically, the monthly giving playbook outlines the stewardship and supporter journey strategies that drive retention improvements.
Whether you need help with retention strategy, monthly giving optimization, or fractional fundraising leadership, we can help you turn these numbers into reality.
