Ending MRR from starting cohort
₹5,20,000.00
The formula
NRR = (Starting MRR + Expansion − Contraction − Churn) / Starting MRR × 100; GRR excludes expansion from the numerator.
Worked example
₹5,00,000 starting MRR + ₹60,000 expansion − ₹15,000 contraction − ₹25,000 churn gives ₹5,20,000 ending cohort MRR, 104% NRR, and 92% GRR.
Frequently asked
Should I include new customers?
No. Include only revenue movements from customers present at the beginning. Use consistent MRR definitions and mutually exclusive contraction and churn amounts.
