Annualized Run Rate

The annualized run rate is an extrapolation. You take the revenue of a short period and project it onto twelve months. If a company earns 10 million euros in one month, its run rate is 120 million euros a year. But the company has not actually earned those 120 million. It would earn them if that month repeated itself exactly twelve times. The number therefore describes a pace, not a bank balance.

Why young tech companies love calculating with it

A company that is growing fast always looks small in hindsight. Annual revenue also includes the weak months from the beginning. If you doubled in January, that barely shows up in the annual revenue figure. The run rate solves this problem because it only looks at the current state. That’s why it has become the standard currency in the startup world.

This is especially visible with AI companies. In recent years they have reported jumps that would fizzle out in a normal annual statement. When a company announces it has reached a run rate of 10 billion dollars, that means: a single strong month was multiplied by twelve. For investors this is still interesting, because they are financing the future, not the past.

But this is exactly where the danger lies. The number sounds bigger than what is actually in the account. It can also be dressed up by choosing a particularly good month as the basis. Serious reports therefore always state the period on which the extrapolation is based.

Projected from one month to twelve

The calculation itself is simple. You take one month’s revenue and multiply by twelve. If you use a quarter, i.e. three months, you multiply by four. There is no fixed rule for which period is the right one. Shorter periods react faster to growth, but fluctuate more strongly.

A comparison helps: the run rate works like a car’s speedometer. Going 120 km/h doesn’t mean you’ve driven 120 kilometers. It means you would cover 120 kilometers if you kept driving exactly like that for an hour. Traffic lights, jams, and breaks aren’t factored in. Likewise, the run rate ignores anything that could change in the coming months.

That’s why it’s only suitable for businesses with fairly steady revenue. For subscriptions it works well, because customers pay every month. For a game maker with a single big holiday hit, it produces nonsense. A special order or a one-off major customer likewise instantly distorts the result twelvefold.

The abbreviation ARR and its pitfalls

In news about startups you’ll almost always come across the abbreviation ARR. It stands for Annual Recurring Revenue, i.e. recurring annual revenue, but is often used synonymously with run rate. Strictly speaking, ARR only counts predictable subscription revenue. Many companies nonetheless lump in one-off payments. If a report doesn’t give details, some skepticism is warranted.

Typical sentences from financial news read: “The company reached an annualized run rate of 500 million dollars.” For you as a reader, this means two things. First: the company is currently growing fast enough that it doesn’t want to state its annual revenue. Second: the figure quoted is a projection, not a balance-sheet number.

A common mistake is confusing run rate with profit. The number describes revenue, not what’s left over in the end. Many AI providers with a billion-dollar run rate are simultaneously posting large losses, because running the models is enormously expensive. Revenue and profit are two different things. Anyone who confuses the two mistakenly considers a growing company to be a healthy one.
