Run rate = revenue in a period x periods per year
A month times twelve, a quarter times four. That is all it is.
It is not a forecast
A forecast accounts for what will change: seasonality, pipeline, churn, planned launches. Run rate accounts for none of it and asserts the last period repeats indefinitely.
That makes it a snapshot. Useful shorthand for scale, and misleading the moment it is treated as a prediction.
It is not ARR either
ARR is the annualised value of committed recurring subscriptions, and it deliberately excludes one-time fees, services, and overage.
Run rate annualises whatever was in the period, which usually includes all three. A month with a large implementation project produces a run rate well above ARR, and reporting that number as ARR is the most common misuse of both terms.
The traps
- Annualising a month with one-time revenue. A single large services
invoice adds twelve times its value to the reported run rate.
- Annualising a seasonal peak. Businesses with a Q4 skew report a January
run rate that never recurs.
- Using it during rapid change. Run rate lags growth and flatters decline,
because it describes a period that has already ended.
- Comparing run rate to someone else's ARR.
A worked example
A month with $720,000 of revenue: $610,000 subscription, $85,000 of implementation, $25,000 of usage overage.
Run rate = 720,000 x 12 = $8,640,000
ARR = 610,000 x 12 = $7,320,000
A $1.3m gap from the same month, and the run rate is not wrong. It is answering a different question, and only one of the two should appear on a slide about recurring revenue.
When it is genuinely useful
- Early-stage, where an annual figure does not exist yet.
- After a step change such as a large launch, where trailing twelve months
understates the present.
- As a sanity check against a forecast. A forecast far from run rate should be
explainable.
Where this sits
Run rate is Measurement in the Tenbound Pipeline Architecture Standard. It is a communication shorthand rather than an operating metric, and nobody should change what they do on Monday because of it.
