If you sell a subscription, MRR is your heartbeat. It’s the predictable revenue you can count on every month — and its direction, up or down, is the most honest summary of how your business is doing.
The math
MRR = number of active customers × average revenue per customer. Thirty customers paying $20 a month is $600 MRR. Annual plans get divided by twelve. That’s it — no accounting degree required.
Why it beats total revenue
A big one-time sale flatters a bad month; MRR can’t be faked that way because it only counts what recurs. Grow MRR and everything else follows. The real question then becomes which of your marketing adds MRR — and that’s where per-post revenue attribution turns MRR from a scoreboard into a map. seenpaid draws it.
