What is Expansion MRR?

Expansion MRR is the additional recurring revenue generated from existing customers in a given period through upsells (higher plan), cross-sells (additional products), seat additions, or usage increases. It does not count revenue from brand-new customers, which is New MRR.

What is a good Expansion MRR rate?

Healthy SaaS businesses target an Expansion MRR rate of 10–30% of Starting MRR per month. The exact benchmark depends on pricing model and customer segment. The key signal is whether Expansion MRR consistently exceeds Churned + Contraction MRR, which produces NRR above 100%.

How is NRR calculated from expansion figures?

NRR = (Starting MRR + Expansion MRR − Contraction MRR − Churned MRR) / Starting MRR × 100. An NRR above 100% means existing customers are generating more revenue over time, so the company can grow even without adding new customers.

What is the difference between Expansion MRR and New MRR?

New MRR comes from customers who did not exist in your base at the start of the period. Expansion MRR comes exclusively from customers who were already active. Keeping them separate lets you evaluate your upsell engine independently from new sales.

What counts as Expansion MRR vs. contraction?

If a customer increases their spend (upgrade, more seats, add-on), the net increase is Expansion MRR. If they decrease their spend but stay subscribed, the net decrease is Contraction MRR. If they cancel entirely, the full amount is Churned MRR.

Summary

Enter your starting MRR plus expansion, contraction, and churn to calculate Expansion MRR and Net Revenue Retention (NRR).

How it works

Enter your starting MRR — total recurring revenue from existing customers at the beginning of the period.
Enter Expansion MRR — additional revenue from upsells, cross-sells, and plan upgrades by existing customers.
Enter Contraction MRR — revenue lost from existing customers who downgraded their plan.
Enter Churned MRR — revenue lost from customers who cancelled entirely.
The calculator derives Ending MRR and NRR: Ending MRR = Starting + Expansion − Contraction − Churn; NRR = (Ending / Starting) × 100.

Use cases

Measure the revenue lift generated by upsell and cross-sell motions each month.
Calculate NRR to benchmark against SaaS industry standards (>100% = growing from existing customers alone).
Identify whether expansion revenue offsets churn and contraction losses.
Model revenue scenarios by adjusting upsell rates before a pricing change.
Present Expansion MRR and NRR to investors as core SaaS efficiency metrics.
Track expansion trends across cohorts to find high-value customer segments.
