RESULT
Calculated output
0

100.00% is the example result. Net revenue retention includes expansion and subtracts contraction and churn from the starting cohort. New-customer revenue belongs outside that cohort.

Result = (([Starting recurring revenue] + [Expansion revenue] − [Contraction revenue] − [Churned revenue]) ÷ ([Starting recurring revenue])) × 100
Purpose

Net revenue retention includes expansion and subtracts contraction and churn from the starting cohort.

Separating growth, retention and subscription capacity

Net revenue retention includes expansion and subtracts contraction and churn from the starting cohort. New-customer revenue belongs outside that cohort. Recurring revenue should be compared across the same starting cohort. Expansion, contraction and churn change retention in different directions. Adding new customers to a retained-customer calculation can conceal losses in the original population.

Source and result record

For nrr, retain Starting recurring revenue, Expansion revenue, Contraction revenue, Churned revenue together with the output. Record the date of the source values and the unit convention used in the form. That record separates a change in the underlying case from a change in how the information was entered. A saved result without its source values cannot show which assumption produced it.

Example with the supplied inputs

Starting recurring revenue: 100000; Expansion revenue: 12000; Contraction revenue: 5000; Churned revenue: 7000. Result: 100.00%. The values are illustrative.

Compare one changed input

Starting recurring revenue changes from 100000 to 110000. The result becomes 100.00%. All other inputs remain fixed.

Calculation rule

Formula

Result = (([Starting recurring revenue] + [Expansion revenue] − [Contraction revenue] − [Churned revenue]) ÷ ([Starting recurring revenue])) × 100

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Starting recurring revenue 100000 Use starting recurring revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.
Expansion revenue 12000 Use expansion revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.
Contraction revenue 5000 Use contraction revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.
Churned revenue 7000 Use churned revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.

Output: 100.00% is the example result. Net revenue retention includes expansion and subtracts contraction and churn from the starting cohort. New-customer revenue belongs outside that cohort. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather Starting recurring revenue, Expansion revenue, Contraction revenue. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Starting recurring revenue on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 100.00%.

Change Starting recurring revenue from 100000 to 110000 while keeping every other value fixed. The result becomes 100.00%. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
