MRR & ARR Calculator — free online
If you run anything with a subscription, sooner or later someone asks how much you make each month, and each year. Doing it by hand on a napkin is easy to get wrong, especially once you have a few plans. We added a free tool that does the math for you — MRR & ARR Calculator — right in your browser.
What it does
It gives you your MRR (monthly recurring revenue) and ARR (yearly recurring revenue) two ways. You can enter your number of customers and your average revenue per account, or you can list out your plan tiers and let it add them up for you. Either way, you get both numbers in a moment.
Nothing leaves your device
The whole thing runs in your browser. Your customer counts and prices stay on your screen — nothing is uploaded, nothing is saved anywhere, and nothing leaves your device. When you close the tab, it's gone.
How to use it
- Open MRR & ARR Calculator.
- Type in your customers and average revenue, or fill in your plan tiers.
- Read your MRR and ARR right there on the page.
It's free with no limit. There are more small tools on the Apps page.
