Donor Acquisition Cost Calculator

What it actually costs to gain a donor

Donor acquisition campaigns (direct mail, digital ads, events aimed at new prospects) always carry a real cost - dividing total campaign spend by the number of new donors gained reveals the true cost per acquisition, a figure that is easy to lose sight of when only tracking total dollars raised.

Worked example

For a $5,000 acquisition campaign that brought in 50 new donors:

Cost Per Donor = 5000 / 50 = 100 per new donor

Frequently asked questions

What counts as a reasonable acquisition cost? There is no universal benchmark - it depends heavily on the acquisition channel and the organization's typical donor lifetime value. The key comparison is always against expected lifetime value, not against acquisition cost in isolation.

Should first-gift revenue be subtracted from this cost? Some organizations do net out the revenue collected during the acquisition campaign itself before calculating cost per donor - decide on one consistent method and apply it the same way each time you calculate this figure, so results stay comparable across campaigns.
