Run Rate Calculator

What is Run Rate?

Revenue run rate is a method of projecting future revenue based on current or recent financial performance. It takes the revenue earned during a specific time period and extrapolates it to estimate what the full-year figure would be if that pace continued unchanged.

For SaaS companies and startups, run rate is one of the most commonly referenced metrics. It gives founders, investors, and finance teams a quick snapshot of the company's revenue trajectory without waiting for a full fiscal year to close. If your startup launched three months ago and has already generated $90,000 in revenue, your annual run rate is $360,000.

Run rate is especially useful for early-stage companies that do not yet have 12 months of revenue data. It provides a forward-looking estimate that helps with budgeting, hiring decisions, and investor conversations.

How Run Rate is Calculated

The calculation is straightforward. Take your revenue from a known period, normalize it to a monthly figure, then multiply by 12 to get the annualized number.

From the annual run rate, you can derive the monthly and daily figures:

• Monthly Run Rate = Revenue / Period in Months
• Annual Run Rate = Monthly Run Rate x 12
• Daily Run Rate = Annual Run Rate / 365

Example

A SaaS company earned $75,000 over the last quarter (3 months):

1. Monthly Run Rate = $75,000 / 3 = $25,000
2. Annual Run Rate = $25,000 x 12 = $300,000
3. Daily Run Rate = $300,000 / 365 = $821.92

When to Use Run Rate

Run rate is most valuable in situations where you need a quick, forward-looking revenue projection:

• Fundraising: Investors frequently ask for your ARR or run rate. It frames your traction in annualized terms, making smaller monthly numbers look more substantial in pitch decks.
• Financial Planning: Use run rate to set quarterly targets, plan headcount, and allocate budgets based on projected revenue.
• Investor Updates: Monthly or quarterly investor reports often lead with run rate to show growth trajectory at a glance.
• Board Meetings: Run rate provides a standard benchmark that board members can track across meetings to gauge progress.
• Scenario Modeling: Adjust the input period to model best-case and worst-case projections based on different months of performance.
• Growth Tracking: Pair run rate with a growth rate calculator to measure how quickly your revenue trajectory is accelerating.

Limitations of Run Rate

While run rate is useful, it has important limitations you should keep in mind:

• Seasonality: If your business has seasonal peaks or dips, a run rate based on a strong quarter will overestimate annual revenue, and a weak quarter will underestimate it.
• One-Time Revenue: Large one-off deals, annual prepayments, or setup fees can inflate the run rate. Strip these out before calculating for a more accurate picture.
• Early-Stage Volatility: Startups with just one or two months of data may see wildly different run rates from month to month. The shorter the period, the less reliable the projection.
• Churn Not Included: Run rate assumes current customers stay. It does not account for churn, downgrades, or failed renewals.

Run Rate vs ARR vs MRR

These three metrics are related but serve different purposes:

• MRR (Monthly Recurring Revenue): The predictable revenue earned each month from active subscriptions. Only counts recurring revenue, excluding one-time charges.
• ARR (Annual Recurring Revenue): MRR multiplied by 12. Like run rate, but strictly limited to recurring subscription revenue.
• Run Rate: A broader projection that can include all revenue types (recurring, one-time, services). Less precise than ARR for subscription businesses, but more flexible for companies with mixed revenue streams.

For pure SaaS companies, ARR and run rate are often identical. For businesses with consulting, setup fees, or variable pricing, run rate will differ from ARR because it includes non-recurring revenue. To evaluate overall business health, combine your run rate with a Rule of 40 calculator that balances growth and profitability.

How to Calculate Run Rate in Excel

If you need to calculate run rate across multiple periods or scenarios in a spreadsheet, use this formula:

Where A1 is the total revenue for the period and B1 is the number of months in that period. To get daily run rate, use =(A1/B1)*12/365. This works in Google Sheets, Excel, and LibreOffice Calc.
