The calculator gives you the number. To see which accounts put it at risk, run your book through a coverage map.
What This Calculator Tells You
NRR measures how much revenue you keep and grow from the customers you already have, before a single new logo is added.
Above 100% means expansion is outrunning churn, and your base compounds.
Below 100% means you are acquiring new customers just to stay flat.
The formula the calculator runs:
NRR = ((Starting Revenue + Expansion - Contraction - Churned Revenue) / Starting Revenue) x 100
Quick example. Start the month with $27,000 in MRR. Customers upgrade, adding $8,000. Others cancel, losing $5,000.
Your NRR is (($27,000 + $8,000 - $5,000) / $27,000) x 100 = 111%.
Even with churn, the base grew 11% in pure revenue.
What To Do With Your Number
Run the calculation, then check it against your segment, not the blended industry average.
Enterprise, mid-market, and SMB sit at very different NRR levels, and the fastest lever to improve the number is usually fixing involuntary churn from failed payments.
For the full breakdown, including 2026 benchmarks by segment, how NRR differs from NDR and GRR, and the three levers that actually move it, read my Net Revenue Retention guide.
