Revenue Run Rate
Projecting what you'd earn in a year if this month's pace held — the Palantír of financial forecasting.
Revenue Run Rate extrapolates current period revenue to a full-year projection, providing a real-time view of revenue scale without requiring 12 months of data. The simplest calculation multiplies the most recent month's revenue by 12, or the most recent quarter's revenue by 4. For a SaaS company generating $500K MRR, the revenue run rate is $6M ARR. For companies with subscription revenue, ARR (Annual Recurring Revenue) is the more precise metric because it explicitly measures contracted recurring revenue from active subscriptions; revenue run rate is a broader concept that applies to any revenue type, including one-time and transactional revenue.
Run rate is most useful in fast-growing companies where waiting for a full fiscal year would make reported results significantly less current than the actual business trajectory. A company that started the year with $1M ARR and grew to $3M ARR in 12 months had average revenue far below its ending run rate — reporting the average understates the current scale. For investor communications, board presentations, and internal planning, run rate provides a more relevant snapshot of current business scale than trailing 12-month totals in high-growth environments.
The limitation of revenue run rate is that it assumes current performance persists indefinitely — the Palantír's flaw of showing only the present moment projected forward, not the actual future. Seasonal businesses, companies with one-time revenue spikes, or companies that just closed an unusually large customer can have run rates that significantly overstate underlying trajectory. Sophisticated investors and operators supplement run rate with organic growth trends, cohort retention data, and contracted versus recognized revenue distinctions to build a more accurate forward-looking picture. Run rate is a useful summary metric rather than a complete financial model.
