Good

You are retaining more revenue than you are losing from your existing base.

Formula

NRR = ((Start MRR + Expansion - Contraction - Churn) ÷ Start MRR) × 100

Worked example

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

Starting MRR
10000
Expansion MRR
2000
Contraction MRR
500
Churned MRR
1000

FAQ & key takeaways

How to read this metric

What it measures

Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from existing customers over a specific period, including expansion revenue and accounting for churn and contraction.

Why it matters

NRR is arguably the most important metric for evaluating a SaaS business’s long-term sustainability. A high NRR (especially above 100%) indicates that your product is so valuable that customers spend more over time, effectively offsetting any churn.

How to improve NRR

  1. Focus on Upselling: Create clear paths for customers to move to higher tiers as they grow.
  2. Reduce Contraction: Understand why customers downgrade and address those friction points.
  3. Aggressive Customer Success: Proactively help customers get more value from your product to prevent churn.
  4. Product-Led Expansion: Design features that naturally encourage more usage or seats as the customer’s team scales.
