Revenue Run Rate

Revenue run rate is an annualized estimate of revenue based on a recent period — most commonly the current month or most recent quarter, scaled to 12 months. It is used as a forward-looking shorthand for where revenue would land if current momentum holds. Run rate is especially useful for fast-growing companies where historical annual figures understate current scale.

formula.sh

Annual Run Rate = Monthly Revenue × 12 (or Quarterly Revenue × 4)

> Monthly Revenue: actual revenue collected or recognized in the most recent month
> Multiply by 12 to annualize
> Quarterly variation: take last quarter revenue × 4 for smoother signal
> Run rate ≠ forecast — it assumes zero growth or decline from current level

example

Your MRR this month is $75,000.

$75,000 × 12

→ $900,000 annual run rate

why it matters

Run rate is the fastest way to communicate the current scale of a business in annual terms. When a startup says "we are at $1M ARR," they often mean their MRR has reached $83,333 — giving a $1M run rate. Investors understand this convention and use it to benchmark against ARR multiples.

Run rate is also useful internally for headcount planning and infrastructure budgeting. If current MRR gives you $1.2M run rate, you can size your support team and server costs against a roughly $1M revenue base for planning purposes.

common mistakes

✗Treating run rate as a forecast — it assumes current revenue is perfectly flat, which is never true

✗Using a single exceptional month (holiday surge, viral spike) as the run rate base

✗Conflating run rate with contracted ARR — run rate is a projection, contracted ARR is committed

pro tips

✓Use a 3-month average as the run rate base to smooth out monthly volatility

✓Always label run rate clearly in investor materials — distinguish it from actual trailing twelve months (TTM) revenue

✓Track the gap between run rate and actual TTM revenue — a large gap in a young company is normal; in a mature one it signals decline

the mrrsucks take

Your run rate is the most optimistic number in your entire deck. It assumes this month repeats forever. It will not. But please, put it in the headline anyway.

faq

Is run rate the same as ARR?+

Not exactly. ARR is specifically the annualized value of recurring subscriptions. Run rate can include all revenue types and is simply current period × 12. For pure SaaS, they are often used interchangeably.

When is run rate misleading?+

When revenue is seasonal, when the base period is anomalous, or when the business is declining. Run rate always assumes current momentum continues, which is a strong assumption.
