Formula
ARR = MRR × 12
Also known as Annual recurring revenue
ARR is the annualised value of a company's recurring revenue, calculated as monthly recurring revenue multiplied by twelve.
ARR = MRR × 12
€37,800 of MRR is €453,600 of ARR.
ARR is the number used in fundraising and valuation conversations, because it states run-rate rather than a single month. It is a projection of the current month, not a record of the past year.
It only applies to genuinely recurring revenue. Annualising a month that included one-off consulting or a large usage spike produces a figure the company cannot repeat.
Plainhub computes arr from money you record in plain words, so it is current when you need it rather than the night before a board meeting.
