ARR Growth Rate Calculator

The ARR growth rate calculator shows you how quickly your annual recurring revenue is expanding over a year. Annual recurring revenue, or ARR, is the value of your subscription contracts on an annualised basis, and its growth rate is one of the headline metrics investors and boards look at when judging a SaaS business. You enter your ARR at the start of the period and your ARR at the end, and the tool returns the growth rate as a percentage along with the dollar value of the net change. The maths is straightforward, the end ARR minus the start ARR, divided by the start ARR, multiplied by 100, but presenting it cleanly makes it easy to drop into a report or a fundraising deck. Founders, chief financial officers and revenue leaders rely on this figure to track year on year momentum, set targets and benchmark against peers. A handful of good-practice tips will keep the number meaningful. First, measure across a consistent twelve month window so each comparison is like for like, rather than mixing partial years. Second, agree whether ARR counts only committed contracted revenue or also includes likely renewals, then apply that definition every time. Third, read the percentage alongside the absolute dollar change, since a high growth rate on a small base can look more impressive than it is while a steady rate on a large base can represent enormous value created. It also helps to pair ARR growth with retention and churn measures, because durable growth comes from keeping customers as well as winning new ones. Used each year, this calculator gives you a clear, repeatable view of how fast your recurring revenue base is scaling.

Growth rate = (end ARR - start ARR) / start ARR. Estimate only, not financial or tax advice.
