Expansion Revenue Rate Calculator

Calculate the percentage of revenue growth from existing customers through upsells, cross-sells, and upgrades.

Expansion Revenue Rate measures the percentage of revenue growth driven by existing customers through upsells, cross-sells, and plan upgrades. It is the most important sign of product-market fit because it shows that customers find increasing value in your product over time. High expansion rates compound growth - companies with 120%+ NRR grow without acquiring a single new customer. This metric is particularly important for investors evaluating SaaS companies because expansion revenue is higher-margin and more predictable than new business. This calculator helps you track how effectively you're growing your existing customer base.

So verwenden Sie diesen Rechner

Enter your beginning MRR at the start of the period and the expansion MRR generated during that period from existing customers.
The calculator will show your expansion revenue rate as a percentage.
Track this monthly alongside churn rate to understand net revenue retention..

Formel und Beispielrechnung

Expansion Revenue Rate = (Expansion MRR ÷ Beginning MRR) × 100:

For example: $15K expansion MRR on $100K beginning MRR = 15% expansion revenue rate.

This means existing customers grew their spending by 15% during the period through upgrades and cross-sells..
