Net Revenue Retention Calculator
Measure how much revenue you keep and grow from existing customers. NRR above 100% means you grow even without new logos.
Use the cohort that started the period — NRR measures revenue retained + expanded from existing customers only (no new logos).
Net Revenue Retention
103%
Ending: $103,000 · Gross retention 88%
Solid — NRR at or above 100% means expansion offsets churn. Push upsell to break into best-in-class territory.

Compare to the 100% break-even and 110%+ best-in-class lines.
Frequently Asked Questions
What is net revenue retention (NRR)?
NRR measures the revenue retained and expanded from existing customers over a period, excluding new customers. (Starting + expansion − contraction − churn) ÷ starting, as a %.
What is a good NRR for SaaS?
100% means expansion exactly offsets losses. 110%+ is best-in-class — you grow from your existing base alone. Under 100% is a leaky bucket.
What’s the difference between NRR and gross retention?
Gross retention (GRR) only subtracts churn and contraction — it can’t exceed 100%. NRR adds expansion, so it can exceed 100%. Both matter.
Why is NRR so important to investors?
High NRR means efficient, compounding growth that doesn’t depend entirely on new-customer acquisition — one of the strongest signals of a durable SaaS business.
How do I improve NRR?
Reduce churn (better onboarding, support, product fit) and drive expansion (upsells, seat growth, usage-based pricing). Fixing churn first usually has the biggest impact.
