How it works
Net revenue retention, or NRR, measures how much recurring revenue you retain and grow from your existing customer base over a period, excluding any new customers, and this calculator computes it as a percentage. You enter the starting recurring revenue from a cohort of existing customers, then the expansion revenue they added through upgrades and cross-sells, the contraction from downgrades, and the churn from cancellations, and it returns the NRR. The metric answers a crucial question for subscription businesses: if you signed up no new customers at all, would your revenue from existing ones grow or shrink? An NRR above 100 percent means expansion outweighs losses, so your customer base grows revenue on its own, a powerful sign of product-market fit and a compounding engine that top SaaS companies prize. An NRR below 100 percent means you are leaking revenue and must constantly acquire new customers just to stay flat. Investors treat NRR as one of the strongest predictors of durable growth and long-term value, often looking for rates well above 100 percent in healthy software businesses. Improve NRR by reducing churn, driving upsells and expansions, and increasing the value customers get. Enter your starting revenue, expansion, contraction, and churn to compute your net revenue retention.
NRR = (start + expansion − contraction − churn) / start × 100
Net revenue retention takes the starting recurring revenue from existing customers, adds expansion from upgrades and cross-sells, subtracts contraction from downgrades and churn from cancellations, and divides by the starting revenue. It measures how much recurring revenue you keep and grow from existing customers alone, excluding revenue from newly acquired ones.

Frequently asked questions
What is net revenue retention?
Net revenue retention, or NRR, is the percentage of recurring revenue you keep and grow from existing customers over a period, excluding new customers. It accounts for expansion, contraction, and churn. An NRR above 100 percent means your existing base grows revenue on its own, a strong signal of a healthy subscription business.
How do you calculate NRR?
Start with the recurring revenue from existing customers at the beginning of the period, add expansion revenue from upgrades and cross-sells, subtract contraction from downgrades and churn from cancellations, then divide by the starting revenue and multiply by 100. The calculator does this when you enter the four figures, giving your net revenue retention percentage.
What is a good NRR?
An NRR of 100 percent means existing customers' revenue is flat. Above 100 percent is good, showing your base grows without new customers, and the best SaaS companies often exceed 120 percent. Below 100 percent means you are losing revenue from existing customers and must acquire new ones just to maintain your total.
How is NRR different from gross retention?
Gross revenue retention counts only losses, subtracting contraction and churn from the starting revenue and capping out at 100 percent. Net revenue retention also adds expansion, so it can exceed 100 percent. Gross retention shows how much you keep, while net retention shows the combined effect of keeping and growing existing accounts.
Why do investors value NRR?
NRR reveals whether a business can grow from its existing customers alone, which signals strong product-market fit and durable, efficient growth. A high NRR compounds over time and reduces reliance on costly new acquisition, making revenue more predictable and the company more valuable. That is why it is among the metrics investors scrutinise most in subscription businesses.
