MRR and ARR calculator for SaaS

MRR (Monthly Recurring Revenue) is the normalized monthly revenue your SaaS earns from subscriptions, and ARR (Annual Recurring Revenue) is that number annualized (MRR x 12). Use the calculator below to work out your MRR, ARR, and a 12-month revenue projection that accounts for both growth and churn.

What MRR is and how to calculate it

MRR is the sum of all recurring revenue normalized to a monthly figure. Annual subscriptions are divided by 12. The basic formula is active paying customers multiplied by average revenue per account.

  • MRR = active customers x average monthly revenue per account
  • Annual plans count as annual value / 12
  • Exclude one-off revenue such as setup fees or services

MRR vs ARR: which one to use

MRR is better for tracking month-to-month momentum and growth velocity. ARR (MRR x 12) is what investors, annual targets, and cross-company benchmarks are usually quoted in.

  • ARR = MRR x 12
  • Use MRR for monthly momentum
  • Use ARR for targets, valuation, and benchmarking

Why the projection needs churn, not just growth

Growing 10% a month with 5% churn is a very different business from growing 10% a month and losing nobody. The projection shows how churn eats into compounding growth over a full year.

  • High churn caps compound growth
  • Small retention gains move year-end ARR a lot
  • Compare scenarios before you spend on acquisition
