Donor lifetime value (DLV)

Donor lifetime value estimates the total amount an organization expects to receive from a donor across the full span of their relationship, not just their most recent gift. It is the nonprofit adaptation of customer lifetime value, and is shaped heavily by donor retention rate: because retention compounds, small improvements in the share of donors who give again have an outsized effect on lifetime value, more so than increasing the size of any single gift.

A common approximate formula is average gift amount × average annual gift frequency × average donor lifespan, though more rigorous models build a retention curve by cohort and tenure and sum expected giving period by period rather than using flat averages, since first-year donors have very different retention odds than multi-year donors. This differs from a single-gift or single-campaign metric, which says nothing about whether that donor will give again.

Organizations use donor lifetime value to justify acquisition spend — a channel that recruits low-value, one-time donors can look efficient on cost-per-gift alone while destroying value compared with a channel that recruits fewer but far more loyal donors, a comparison usually made through Fundraising ROI. The main pitfall is calculating it from too short a giving history, which understates true value for a young donor file; a rolling estimate should discount for donors who have already become a lapsed donor, and should not be conflated with wealth capacity from wealth screening rather than actual demonstrated giving behavior.
