Understand Nonprofit Donor Lifetime Value
One idea, three depths
Choose how deeply to explain Nonprofit Donor Lifetime Value
Nonprofit Donor Lifetime Value: Estimate contribution value from recurring gifts, retention and service cost over a selected horizon.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Nonprofit Donor Lifetime Value to answer this question: estimate contribution value from recurring gifts, retention and service cost over a selected horizon? Enter Average annual donor contributions, Annual processing and stewardship cost, Annual donor retention rate, and 2 other inputs; the calculator shows Projected donor lifetime net value. Try changing one number and watch what happens to Projected donor lifetime net value. The answer tells you Projected donor lifetime net value.
Age 15Explain it to a 15-year-oldConnect it to the formula
This is a planning model; donor behavior, inflation, restricted gifts and stewardship can change. The rule is Donor value = annual net gifts × retained-life factor − acquisition cost. Its input values are Average annual donor contributions, Annual processing and stewardship cost, Annual donor retention rate (%), Selected projection years, Acquisition cost per donor, and the main result is Projected donor lifetime net value. Try changing one number and watch what happens to Projected donor lifetime net value.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Donor value = annual net gifts × retained-life factor − acquisition cost, evaluated from Average annual donor contributions, Annual processing and stewardship cost, Annual donor retention rate (%), Selected projection years, Acquisition cost per donor to produce Projected donor lifetime net value. This is a planning model; donor behavior, inflation, restricted gifts and stewardship can change. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Estimate contribution value from recurring gifts, retention and service cost over a selected horizon.
Why the business model works
This is a planning model; donor behavior, inflation, restricted gifts and stewardship can change.
Inputs and operating assumptions
This model uses Average annual donor contributions, Annual processing and stewardship cost, Annual donor retention rate, Selected projection years, Acquisition cost per donor. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Donor value = annual net gifts × retained-life factor − acquisition cost
What the calculator produces
The primary output is Projected donor lifetime net value; it also exposes Expected retained donor-years, Projected gross contribution value. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
