Net Retention Rate: The Metric Every SaaS Leader Should Obsess Over

When you're growing a SaaS business, it's easy to get caught up in chasing new logos. But the real secret to sustainable growth? Keeping—and expanding—your existing customer base. That's where Net Retention Rate (NRR) comes in: a single number that reveals whether your product is truly delivering value, and if your business is built for the long haul.

What Is Net Retention Rate?

Net Retention Rate (sometimes called Net Revenue Retention) measures how much recurring revenue you keep from your existing customers over a given period, factoring in upgrades, downgrades, and churn. In short: it shows whether your current customers are sticking around and spending more.

Why does it matter?
SaaS companies with high NRR grow faster, need less new business to hit targets, and are much more attractive to investors. According to industry benchmarks, a world-class NRR is 120%+—meaning your existing customers are not just staying, but expanding.

How to Calculate Net Retention Rate

Starting MRR: Monthly recurring revenue from existing customers at the beginning of the period.
Expansion MRR: Revenue gained from existing customers (upgrades, cross-sells).
Churned MRR: Revenue lost from customers who canceled.
Contraction MRR: Revenue lost from downgrades.

Example:

You start the month with $10,000 MRR from current customers. During the month, you add $2,000 from expansions, lose $1,000 to churn, and $500 to downgrades.

NRR = (10,000 + 2,000 - 1,000 - 500) / 10,000 × 100 = 105%

That means you're growing revenue from your existing base—even before landing a single new customer!

Why NRR Should Be a Key Metric for Your SaaS

Signals Product-Market Fit:

High NRR means customers love your product enough to stay and buy more.

Predicts Long-Term Growth:

Investors and acquirers look at NRR as a sign of healthy, sustainable growth.

Reduces Pressure on Acquisition:

The higher your NRR, the less you need to rely on costly new customer acquisition.
