Customer Growth Rate Calculator
Measure how fast your customer base is growing over any period, net of churn.
Customer growth rate
What it measures
Customer growth rate is the net change in customers over a period divided by the starting count. It nets new wins against losses in one number.
Why it matters
Net growth is what compounds. A team adding 50 logos while losing 40 is working five times harder than its growth rate shows.
A worked example
From 300 customers to 345 in a quarter is 15 percent growth. Annualised, that pace roughly *1.75x*es the base in a year.
How to read and improve it
Split the number into gross adds and churn before acting on it. The same 15 percent can hide very different businesses.
Frequently asked questions
Should I count free users?
Track paying customers for this metric. Free user growth is a different funnel stage.
Net or gross growth?
This calculator gives net. Report both internally so churn stays visible.
