Revenue run rate

metrics & financeUpdated October 2026 · reviewed by the Forge team

also known as revenue run rate

A projection of annual revenue based on current performance - taking a recent period and extending it across a full year.

For example, if an agency billed $90,000 last month, its annualised run rate is about $1,080,000. It is a quick way to size the business today, though it assumes the current month is representative.

Why it matters to your firm: run rate gives a fast, current-state read on the size of the business - useful for planning and goal-setting. Its weakness is that it assumes today continues unchanged, so it can mislead if the latest period was unusually strong or weak.

How to calculate

Annual run rate = revenue in a period × number of those periods in a year

E.g. monthly revenue × 12 - best used when the period is representative.

Common questions

Frequently asked questions

What is revenue run rate?

A projection of annual revenue based on current performance - taking a recent period and extending it across a full year.

How do you calculate run rate?

Take revenue from a recent period and multiply it out to a year - for example, monthly revenue times twelve.

What is the difference between run rate and ARR?

ARR counts only recurring revenue; a revenue run rate can annualise total revenue, including one-off work, so it is broader and rougher.

When is run rate misleading?

When the base period is not representative - a bumper month or a seasonal dip will distort the annualised figure.
