Run rate: how to calculate it, and the four ways it misleads

The run rate formula, the choice of window and why it matters, a worked example against a seasonal and a lumpy business, the four ways run rate misleads, seasonality, one-off orders, a short window and a trend, and the rule for when to annualise and when not to. With the account-level use that makes run rate a ranking rather than a forecast.

The short answerRun rate is revenue over a recent window, scaled to a longer period: the last three months times four is an annualised run rate. It is a description of the present, not a forecast. It misleads when the business is seasonal, when the window holds a one-off order, when the window is too short to be stable, and when there is a trend the flat scaling ignores. Per account, with a stated window, it is a reliable way to rank: which dormant account was worth the most, which customer is growing fastest. As a company forecast it is only as good as the four assumptions.

Run rate is the number that gets quoted when the year is not over. It is easy to compute and easy to compute wrongly, and the wrongness is invisible because the formula is so simple. This guide gives the formula, the window, a worked example, the four ways it misleads, and the per-account use that avoids most of them.

The formula

Run rate = revenue in the window ÷ window length × target period length

Three months of $1.2m, annualised: $4.8m. One month of $400,000, annualised: $4.8m. Both are run rates. Only one of them is stable.

The window

Window Stable? Current? Use
1 month No Very Rarely
3 months Usually Yes Monthly-ordering accounts
6 months Yes Somewhat Lumpy accounts
12 months Very No, it is the trailing year Seasonal businesses; baselines

Stated on every figure. A run rate with no window is a number without a meaning.

A worked example

A company with a strong fourth quarter.

Quarter Revenue Annualised run rate from that quarter
Q1 $3.0m $12.0m
Q2 $3.4m $13.6m
Q3 $3.6m $14.4m
Q4 $6.0m $24.0m
Year $16.0m

The Q4 run rate overstates the year by half. The Q1 run rate understates it by a quarter. The trailing twelve months says $16m, and the growth from Q1 to Q3 says the next year will be higher than that. None of the four quarterly run rates is a forecast.

The four ways it misleads

Seasonality. The quarter above. Use a trailing twelve, or compare the window to the same window last year and scale the prior year.

One-off orders. A $900,000 project order in a three-month window adds $3.6m to the annualised figure and will not repeat. Exclude orders flagged as one-off, or use a longer window, and state which.

A short window. One month of a lumpy account is noise. The window has to hold several of the account's normal orders.

A trend. A business growing 5 percent a quarter has a run rate that is already behind. Run rate is flat by construction; if the trend matters, show it beside the run rate rather than baking it in.

Per account: run rate as a ranking

Per account, with the same window for all, run rate is a value:

Use Ranked by
Dormant list Run rate in the window before the account went quiet
Growth list Change in run rate, this window against the prior
Concentration Run rate, so one large month does not distort the share
Gap valuation Norm minus run rate, so the gap is against a stable actual

Ranking is robust to the four problems in a way that a total is not: an account's seasonality affects its rank only against accounts with different seasonality, and the window is the same for all.

The identity

Σ accounts' window revenue = ledger revenue in the window

Run rate per account rolls up to run rate for the company only if the account revenue sums to the ledger. Check it first.

Where it goes wrong

Window unstated. Two people quote two run rates and both are right.

Q4 annualised in January. The budget that follows is a third too high.

Run rate presented as forecast. The pipeline is never asked about.

Per-account windows differ. The ranking compares a one-month figure to a six-month one.

Every month, with the window on it

Mapped once, the ledger produces run rate per account, per rep and per company at a stated window every month, with the one-off flags and the trend beside it. Covirage builds this from the export as it is. The run rate term has the short definition, and the dormant threshold guide covers the list that run rate most often ranks.

Questions people ask

What window should be used?

Long enough to be stable, short enough to be current. Three months is common for monthly-ordering accounts; for a lumpy business, six or twelve. The window is stated with the figure and the same for every account in a comparison.

Is run rate a forecast?

No. It is the present scaled up. A forecast adds pipeline, seasonality and known changes. Run rate is the floor that a forecast should be compared to, and the difference is what the forecast is claiming.

How is run rate used per account?

As a value for ranking. The dormant list ranked by run rate before the account went quiet; the growth list by the change in run rate; the concentration figure by run rate rather than a single month. It is more useful as a ranking than as a total.
