Net revenue retention, or NRR, measures how much recurring revenue you keep and grow from existing customers over a period, ignoring brand new signups. It is one of the most watched health metrics for subscription businesses because an NRR above one hundred percent means your base grows on its own even before you add a single new customer. This calculator starts with your beginning recurring revenue, adds expansion from upgrades, then subtracts contraction from downgrades and revenue lost to churn, and divides the result by the starting figure. It also reports gross revenue retention, which excludes expansion and shows the floor of what you retain. Enter your four figures and both percentages update at once. Use NRR to prove durable growth to investors and to focus on upsells and retention rather than only new sales. All calculations run locally in your browser.
It starts from beginning MRR, adds expansion, then subtracts contraction and churn, and divides by starting MRR as a percent.
GRR excludes expansion, so it only measures revenue kept, while NRR includes upsells and can exceed 100 percent.
It means expansion from existing customers more than offsets churn, so revenue grows even with no new customers.
