How to calculate annual run rate (ARR run rate)
Annual run rate turns a short period of revenue into an annualized figure, giving a quick sense of scale. For recurring revenue, it is essentially the same as ARR (MRR times 12).
The caveat is the assumption that the current rate continues. Run rate is useful for stable businesses but overstates or understates badly when revenue is growing fast, shrinking, or seasonal.

- Assumes rate holds The key assumption
- Misleads in flux Growth or seasonality
Short answer
Annual run rate annualizes current revenue by projecting it forward. Multiply a recent period's revenue by the number of those periods in a year: monthly revenue times 12, or quarterly times 4. If last month's revenue was 200,000 dollars, the annual run rate is 2,400,000 dollars. It assumes the current rate holds, so it misleads during rapid change.
Step by step
Pick a recent period
Choose a representative recent period, usually the latest month or quarter, whose revenue reflects the current rate.
Multiply to annualize
Multiply monthly revenue by 12 or quarterly revenue by 4 to project it across a full year.
Use recurring revenue for ARR
For a recurring-revenue run rate (ARR), use MRR times 12 and exclude one-time fees, matching the ARR definition.
Sanity-check the assumption
Confirm the chosen period is representative. If revenue is growing fast, shrinking, or seasonal, note that the run rate over or understates the true annualized figure.
Worked example
Last month you earned 250,000 dollars of recurring revenue. Annual run rate = 250,000 x 12 = 3,000,000 dollars, which equals your ARR.
But if you closed a large one-time deal last month, including it would inflate the run rate to a level you will not sustain. And if you are growing 10 percent monthly, a static run rate understates where you will actually be in a year. Always sanity-check the base period.
How Ardovo handles it
Ardovo computes run rate from recurring revenue, excluding one-time items so it equals a clean ARR. Rook flags when a chosen base period is distorted by a one-time deal or rapid growth, so the run rate is not taken at face value.
Frequently asked questions
What is the annual run rate formula?
A recent period's revenue multiplied by the number of those periods in a year: monthly revenue times 12 or quarterly times 4. For recurring revenue it equals ARR, using MRR times 12 and excluding one-time fees.
Is annual run rate the same as ARR?
For recurring revenue, effectively yes: ARR is MRR times 12, a run rate. The term run rate is broader and can annualize any revenue, including one-time items, which ARR always excludes. Keep the base clean for an ARR-equivalent figure.
When does run rate mislead?
When the base period is not representative: during rapid growth or decline, or when a one-time deal inflates it, or with seasonal revenue. Run rate assumes the current rate continues, which fails during any significant change.
