The formula
MRR = customers × ARPA net new MRR = new + expansion − contraction − churned MRR growth = net new MRR ÷ starting MRR ARR = MRR × 12
Only recurring revenue counts. One-off fees such as setup and services stay out, and a yearly plan counts as its price ÷ 12.
What to watch out for
Take customers and ARPA from the first day of the month, then enter what changed during it. Leave out trials and anything that does not recur.
Frequently Asked Questions
How do I calculate MRR?
Multiply customers by average revenue per account. 200 customers paying 50 a month is 10,000 MRR, or 120,000 ARR.
How is MRR growth calculated?
Divide net new MRR by starting MRR. Starting at 10,000 with 800 new, 300 expansion, 100 contraction and 200 churned, net new MRR is 800 and growth is 8.00%.
Should a yearly plan count in full?
No. Spread it over the months it covers. A plan of 1,200 a year adds 100 to MRR.
