Net revenue retention: Measure recurring revenue retained after churn, contraction and expansion.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Net revenue retention to answer this question: measure recurring revenue retained after churn, contraction and expansion? Enter Starting recurring revenue, Churned revenue, Contracted revenue, and 1 other input; the calculator shows Net revenue retention. Try changing one number and watch what happens to Net revenue retention. The answer tells you Net revenue retention.
Age 15Explain it to a 15-year-oldConnect it to the formula
NRR follows only the starting customer cohort. Values above 100% mean expansion more than offset churn and contraction. The rule is NRR = (starting revenue − churn − contraction + expansion) ÷ starting revenue × 100. Its input values are Starting recurring revenue, Churned revenue, Contracted revenue, Expansion revenue, and the main result is Net revenue retention. Try changing one number and watch what happens to Net revenue retention.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is NRR = (starting revenue − churn − contraction + expansion) ÷ starting revenue × 100, evaluated from Starting recurring revenue, Churned revenue, Contracted revenue, Expansion revenue to produce Net revenue retention. NRR follows only the starting customer cohort. Values above 100% mean expansion more than offset churn and contraction. 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
Measure recurring revenue retained after churn, contraction and expansion.
Why the business model works
NRR follows only the starting customer cohort. Values above 100% mean expansion more than offset churn and contraction.
Inputs and operating assumptions
This model uses Starting recurring revenue (at least 0.01), Churned revenue (at least 0), Contracted revenue (at least 0), Expansion revenue (at least 0). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
NRR = (starting revenue − churn − contraction + expansion) ÷ starting revenue × 100
What the calculator produces
The primary output is Net revenue retention; it also exposes Ending cohort revenue. 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.
