Example

Using the default inputs, the result is:
$50,000.00
Paying customers
250
ARPA per month
$200

Formula

MRR = Paying Customers × ARPA (monthly)
  • This is a simplified estimate; real MRR sums subscription amounts.

FAQ

Does MRR include one-time fees?
Typically no—MRR focuses on recurring revenue only. Track one-time fees separately.

How to interpret

MRR best practices
  • Use ‘committed’ MRR (active subscriptions) rather than invoices.
  • Break down changes: new, expansion, contraction, churn.
  • Track net new MRR to see momentum.
