Definition
A run rate turns a short recent period into an annual figure, for example one month's revenue multiplied by twelve or one quarter's multiplied by four. It describes the pace a business is running at now rather than what it achieved over a full year. It is a projection, not a result, and it assumes the recent period will repeat.
Worked example
Lanternfish Analytics is a fictional Canadian software business. In its best month ever it billed C$50,000, and its listing quotes a "C$600,000 revenue run rate".
- Revenue over the trailing twelve months was C$450,000.
- The last three months averaged C$40,000, which annualises to C$480,000.
The C$600,000 figure describes one strong month. The full year and the latest quarter both tell a more modest story.
Trailing twelve months means the most recent 12 consecutive months of figures, whatever the financial year. It gives a more current view than the last set of annual accounts.
Why buyers care
Sellers tend to quote a run rate when recent months look better than the year as a whole. That can be fair for a subscription business growing steadily with low churn. It can mislead where sales are seasonal, where a large one-off order landed in the chosen month, or where a price rise or discount has not yet settled.
Ask which period the run rate uses and why it was chosen. Then ask for monthly revenue for the last two years and compare the run rate with the trailing twelve months figure. Loupe's valuation tool asks for revenue over the last 12 months rather than a run rate. For SaaS businesses it values annual recurring revenue, which is itself a run rate of current subscriptions, so it also adjusts for churn, growth and net revenue retention and cross-checks the result against SDE.
Churn is the rate at which a business loses customers or recurring revenue over a period. Customer churn and revenue churn can tell very different stories.
Annual recurring revenue (ARR)
Annual recurring revenue is the yearly value of subscription or contracted revenue expected to repeat, measured at a point in time. Software businesses are often priced as a multiple of it.
