The Growth Within

This formula measures the underlying financial expansion (or recession) of the customer base you already own.

NRR = (Starting MRR + Expansion MRR - Downgrade MRR - Churn MRR) / Starting MRR * 100

How it’s used

You track a specific cohort of clients over a single month. Input your Starting Monthly Recurring Revenue, and map exactly how much new revenue you successfully upsold them versus how much was bled out to downgrading tiers or full cancellations.

Why it matters

If your NRR is over 100%, your agency or SaaS is structurally growing even if you don’t acquire a single new customer that month. It profoundly shifts your business focus away from expensive front-end acquisition toward improving back-end product value, usage, and dedicated customer success teams.

Frequently Asked Questions

It's the holy grail of SaaS. It occurs when your NRR is above 100%, meaning the extra money you make from upselling existing customers completely covers the revenue lost from customers who cancel.
No. NRR strictly measures the cohort of customers you already had at the start of the month. It tests the stickiness of your product, not the efficiency of your sales team.
