MRR

Also called Monthly recurring revenue.

MRR, or monthly recurring revenue, is the money your subscriptions bring in each month.

Add up what every paying customer pays per month. Turn yearly plans into a monthly amount: $1,200 a year counts as $100 of MRR. Leave out one-time fees. Multiply MRR by 12 and you get ARR.

Most SaaS founders track it first, because it shows growth month by month. Each month, write down new MRR, MRR lost to churn, and MRR from upgrades. Compare it with customer acquisition cost to see if growth pays. Your pricing sets how fast it can grow.
