A SaaS MRR calculator helps subscription software sellers see how much predictable revenue they earn each month. Founders, finance leads, and small SaaS teams can use it to track monthly recurring revenue before they plan hiring, pricing, or budgets.

Steps to find your monthly recurring revenue

Gather the recurring monthly amounts from your subscriptions, such as plan prices paid each month.
Enter those amounts in the input fields at the top of the page.
Check that every value is monthly, not yearly, before you calculate.
Run the calculation and read the MRR result shown on the page.

Who uses MRR tracking

Founders checking whether a subscription business is growing.
Finance staff preparing monthly reports for investors or owners.
Sales teams comparing monthly plans with annual contracts.
Small software sellers setting prices for new plans.

Reading your MRR figure

MRR is shown as an amount per month in the currency you entered. It describes the steady monthly income from subscriptions, so it does not include one-time setup fees or occasional purchases.

Mistakes that inflate MRR

Adding yearly payments without dividing them by 12 first.
Counting trial users or unpaid accounts as paying customers.
Including one-time fees, which do not repeat each month.
Mixing currencies without converting them to one currency first.

Common questions about SaaS MRR

What does MRR stand for?

MRR stands for monthly recurring revenue. It is the total amount of subscription income you expect to receive each month.

Should I include annual plans in MRR?

Yes, but only as their monthly equivalent. Divide the annual price by 12 so the figure reflects one month of income.

Is MRR the same as revenue?

No. Revenue can include one-time payments, while MRR counts only recurring subscription income.

Does this calculator account for churn?
