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.

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.

Revenue for selected period

Period

Use revenue from a single recent month. Run-rate = monthly revenue × 12.

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

Example

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

Annualized revenue run-rate:

Monthly revenue run-rate:

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).

How to Use the Run-Rate (Annualized revenue run-rate) Calculator

Enter your revenue for a specific period, choose whether that number is monthly, quarterly, or annual, and the tool will annualize it into an ARR-style run-rate plus a comparable monthly pace.

Enter revenue for the selected period
- In “Revenue for selected period,” input the revenue amount you want to annualize (e.g., last month revenue, last quarter revenue, or last 12 months revenue).
Choose the period that matches your number
- - Select Monthly if your input is one month.
- Select Quarterly if your input is one quarter (3 months).
- Select Annual if your input is a full 12-month total.
Read the annualized run-rate and monthly pace
- - The calculator converts your input into an annualized figure and a normalized monthly pace.
formula (plain text): monthly run-rate = revenue for period / months in period
formula (plain text): annualized run-rate = monthly run-rate × 12 = revenue for period × (12 / months in period)
Use the “Revenue band” for quick context (not precision)
- “Revenue band (run-rate)” buckets you into a rough scale range (e.g., < $1M, $1–3M). Treat it as a sanity check, not a valuation or forecast.
Review “Revenue period used” + share/reset as needed
- - Confirm the tool is interpreting your input correctly (last month / last quarter / last 12 months).
- Use Share / Embed to copy a shareable result, or Reset to start over.
