How it works & examples
What is net revenue retention (NRR)?
NRR measures how recurring revenue from an existing customer cohort changes after expansion and losses. New-customer revenue is excluded.
How to use this tool
NRR = (starting MRR + expansion MRR − lost MRR) ÷ starting MRR × 100. Use the same cohort throughout. Include both cancellations and downgrades in the loss field if measuring total revenue contraction.
Example
$10,000 starting MRR, $2,000 expansion, and $500 lost MRR gives NRR of 115%.
Understanding your result
Above 100% means the cohort’s revenue grew; below 100% means it shrank. The form labels the loss field “Churned MRR,” so results omit downgrades unless you include them there. Starting MRR must be positive.
