Revenue Run-Rate (ARR-style) Calculator

Annualize recent revenue into a simple ARR-style run-rate. Enter revenue for a month, quarter, or year and see the implied annual and monthly run-rate plus a rule-of-thumb revenue band.

$

Total revenue for the period you choose below (month, quarter, or year). For an ARR-style run-rate, use mostly recurring revenue and exclude large one-off or project-only items.

Choose the period that matches your revenue input. The calculator scales it to a 12-month run-rate.

Scenarios

What is Revenue Run-Rate (Annualized revenue run-rate)?

Revenue run-rate is an annualized projection of revenue based on a recent period (month, quarter, or trailing 12 months), assuming that level continues.

It’s a fast way to frame scale, set top-line expectations, and anchor value creation conversations around growth, operating leverage, and capital efficiency.

It’s most useful when the business is changing quickly—but it can mislead if revenue is seasonal, lumpy, or inflated by non-recurring items (e.g., services, one-offs, pull-forwards).

Formula

Annualized Revenue Run Rate = Revenueperiod × 12 / Monthsperiod
Monthly Revenue Run Rate = Revenueperiod / Monthsperiod
If period = 1 month: Annualized = Revenuemonth × 12
If period = 1 quarter: Annualized = Revenuequarter × 4
If period = 12 months: Annualized = RevenueTTM

Example

A company did $150,000 in revenue in the last month.

Annualized revenue run-rate: 150,000 × 12 = 1,800,000
Monthly revenue run-rate: 150,000 / 1 = 150,000

That frames the business at roughly $1.8M annualized revenue based on the most recent month, which can be compared against targets, margin structure (gross margin, EBITDA margin), and efficiency metrics (CAC, LTV, burn multiple).

Frequently Asked Questions

How do I calculate annualized revenue run-rate from one month, one quarter, or the last 12 months?

Enter revenue for the period you have, select Monthly / Quarterly / Annual, and the calculator annualizes it using: annualized run-rate = revenue for period × (12 / months in period).

Why does the same revenue input give different annualized run-rate when I switch Monthly vs Quarterly vs Annual?

Because the input means “revenue for that selected period.” $150,000 as a month implies $150,000 × 12; $150,000 as a quarter implies $150,000 × 4; $150,000 as a full year stays $150,000.

Is annualized revenue run-rate the same as ARR (Annual Recurring Revenue)?

No. Run-rate annualizes whatever revenue you enter (can include one-time or seasonal revenue). ARR usually means recurring subscription revenue only, based on active contracts/subscriptions (often MRR × 12).

What period should I use (last month vs last quarter vs last 12 months) so the number is not misleading?

Use the most representative period for “forward pace.” If revenue is volatile or seasonal, prefer last quarter or a normalized month (or average the last 3 months) rather than a single unusually high/low month.
