Dear CFO by Phoenix Strategy Group

Monthly recurring revenue (MRR)

Monthly recurring revenue is the predictable subscription revenue a business expects to bill every month, normalized to a monthly amount.

Formula

MRR = Sum of monthly subscription charges for all active customers (annual plans ÷ 12)

Worked example

180 customers on a $400 a month plan$72,000
40 customers on a $1,000 a month plan$40,000
5 customers on $24,000 annual contracts$24,000 ÷ 12 = $2,000 a month each, so $10,000

$72,000 + $40,000 + $10,000 = $122,000 MRR

Why it matters

MRR is the baseline a subscription business plans against. Because it moves a little every month, it shows growth, churn and pricing changes long before they add up in annual revenue.

Common mistakes

Where it misleads

Counting one-time fees, such as setup or consulting, which will not repeat next month.

Booking a full annual contract as one month of MRR instead of spreading it over twelve.

Leaving discounts out, so MRR reflects list prices rather than what customers actually pay.

Stop calculating it by hand.
