How to use this calculator

Enter active customers, average revenue per account, expansion revenue rate, and churn rate. The calculator estimates MRR, ARR, and NRR.

What the result means

NRR above 100% means expansion revenue offsets churn. Below 100% means the existing customer base is shrinking before new sales.

MRR = customers × ARPA. ARR = MRR × 12. NRR = (MRR + expansion − churned revenue) ÷ MRR.

Revenue growth is stronger when expansion revenue exceeds churned revenue.

Example calculation

With 500 customers at $120 ARPA, MRR is $60,000 and ARR is $720,000. With 10% expansion and 4% churn, NRR is 106%.

Tips for better results

  • Increase expansion revenue with upgrades.
  • Reduce churn through onboarding and support.
  • Track MRR and ARR separately.

FAQ

How do I calculate SaaS MRR?

Multiply active customers by average revenue per account.

What is ARR in SaaS?

ARR is annual recurring revenue, usually calculated as MRR multiplied by 12.

How does churn affect revenue?

Churn reduces MRR and forces new sales to replace lost revenue before net growth occurs.

What is net revenue retention?

NRR measures how existing customer revenue changes after expansion and churn.

What is a good SaaS growth rate?

A good growth rate depends on stage, but high growth with low churn and strong NRR is healthier.
