Revenue Run Rate Calculator

Run rate is the annualized projection of a short revenue period. To calculate it, take the revenue from a known period (such as a month or a quarter) and multiply by the number of such periods in a year. Monthly revenue times 12 equals annual run rate; quarterly revenue times 4 equals the same figure.

Annual Recurring Revenue (ARR) is a contractual figure representing the total value of active subscription contracts annualized as of today. Run rate is a financial extrapolation based on recent actual revenue. For subscription businesses, ARR is the more accurate forward-looking metric because it excludes non-recurring deals and already accounts for cancellations up to the measurement date.

Run rate is unreliable when the measurement period is not representative. Annualizing a seasonally strong quarter overstates likely revenue, and annualizing a period with a one-time large deal that will not repeat does the same. It also ignores churn, so for subscription businesses the true forward revenue can be lower than run rate suggests even when no explicit growth assumption is applied.

Investors often use ARR or revenue run rate as a quick baseline for applying a revenue multiple to estimate valuation, particularly for early-stage SaaS companies with limited history. The growth rate applied to the run rate matters more than the starting figure in most cases, since a lower run rate growing at 100 percent annually becomes more valuable than a higher run rate growing at 10 percent within a few years.
