Compound Sales Growth (CAGR) Calculator

About the Compound Sales Growth (CAGR) Calculator

Compound Annual Growth Rate (CAGR) is the gold standard for measuring how consistently a business's revenue has grown over multiple years. Unlike simple growth rates that can be distorted by individual year volatility, CAGR smooths out the ups and downs to reveal the underlying growth trajectory — the steady annual rate at which your business would have needed to grow each year to get from Point A to Point B.

CAGR is particularly valuable because it enables true apples-to-apples comparisons. You can compare a company's 3-year CAGR against its 5-year CAGR to see if growth is accelerating or decelerating. You can compare different business lines, competitors, or markets over different time periods. And you can use it to project future revenue based on historical trends.

This calculator computes CAGR from any starting and ending value over any time period, projects future revenue at the calculated rate, and provides comparison scenarios so you can model how different growth rates lead to dramatically different outcomes over time.

When This Page Helps

CAGR cuts through noise to reveal your true growth trajectory. A business that grew 50% one year and 0% the next looks very different from one that grew 22.5% both years, yet they end at the same place. CAGR captures this smoothed reality. This calculator helps you compute CAGR, project where it's taking you, and compare your rate to industry benchmarks and growth targets.

How to Use the Inputs

1. Enter your beginning revenue (starting point)
2. Enter your ending revenue (current or target)
3. Enter the number of years between the two values
4. Review your CAGR and equivalent monthly growth rate
5. Analyze the forward projection table at your current CAGR
6. Compare growth trajectories across different CAGR scenarios

Example Calculation

Tips & Best Practices

• Compare 1-year, 3-year, and 5-year CAGR to detect acceleration or deceleration trends
• Use CAGR to set realistic multi-year targets for board presentations and investor communications
• Remember that CAGR masks volatility — actual year-to-year growth will vary around the average
• Benchmark your CAGR against industry median and top-quartile performers
• Higher CAGR is easier to sustain at smaller scale; expect CAGR to naturally decline as you grow
• For SaaS companies, 30–50% CAGR typically qualifies as "high growth" for investors
• Calculate CAGR for different segments (product lines, geographies) to identify growth engines

The Mathematics of Compound Growth

Compound growth is one of the most powerful forces in business and finance. Unlike linear growth where you add a fixed amount each year, compound growth builds on itself — each year's growth is calculated on the larger base from the prior year. This creates exponential curves where small differences in rate produce enormous differences in outcome over time. A 25% CAGR over 10 years produces a 9.3× multiple on your starting value, while 35% produces 20.1×.

Using CAGR for Investor Communications

Investors universally use CAGR to evaluate and compare growth businesses. When presenting to investors, include your 1-year, 3-year, and 5-year CAGR to show trend direction. Include market CAGR alongside your company CAGR to demonstrate whether you're gaining or losing market share. Present CAGR for both revenue and profitability (or contribution margin) to show sustainable growth quality.

CAGR Limitations and Supplements

While CAGR is invaluable, it has blind spots. It ignores path — whether growth was volatile or steady. It ignores duration within periods — a company that grew entirely in January shows the same annual CAGR as one that grew steadily. Supplement CAGR with year-by-year growth rates to show consistency, coefficient of variation to quantify stability, and segment-level analysis to reveal growth composition.

Multi-Scenario CAGR Planning

The best growth planning uses multiple CAGR scenarios. Build three cases: a conservative scenario based on historical floor performance, a base case using recent trends, and a stretch scenario assuming execution improvements. Map resource requirements for each scenario. This framework gives leadership realistic expectations while providing aspirational targets that drive better execution.

Frequently Asked Questions

• What is CAGR and why is it important?

  CAGR (Compound Annual Growth Rate) represents the constant annual rate at which a value would need to grow to go from a beginning value to an ending value over a given number of years. It's important because it provides a smoothed, comparable metric that eliminates year-to-year volatility, making it the standard for comparing growth across different businesses, time periods, and investments.

• How is CAGR different from average growth rate?

  A simple average growth rate adds up annual rates and divides by the number of years, but this can be misleading. If revenue doubles one year (+100%) and halves the next (−50%), the average growth rate is 25%, but the actual CAGR is 0% because you end where you started. CAGR uses geometric (compound) math that accurately reflects the actual end result.

• What is a good CAGR for a growing business?

  Benchmarks vary by stage and industry. Early-stage startups ($0–$5M revenue) might target 100%+ CAGR. Growth-stage companies ($5–$50M) typically target 40–80%. Mature businesses ($50M+) target 15–40%. The S&P 500 historically delivers about 7–10% CAGR. Context matters enormously — a 25% CAGR in a market growing 5% is impressive, but the same rate in a 40% growth market means losing share.

• Can CAGR be negative?

  Yes, if the ending value is less than the beginning value, CAGR is negative. This means the business is shrinking at a compound rate. A negative CAGR signals systemic decline rather than temporary setbacks. For example, going from $10M to $6M over 3 years gives a CAGR of −15.6%, meaning revenue declined at approximately 15.6% annually on a compound basis.

• How do I use CAGR for forecasting?

  Multiply your current revenue by (1 + CAGR) raised to the power of the number of future years. This assumes growth continues at the historical rate. While no forecast is perfect, CAGR-based projections are reasonable for businesses with consistent growth drivers. Always present multiple scenarios (conservative, base, aggressive) rather than relying on a single projection.

• Does CAGR account for interim cash flows?

  No. CAGR only considers the beginning and ending values, ignoring what happened in between. A company that dipped 80% in year 2 but recovered by year 5 would show the same CAGR as one that grew steadily. For investments with interim cash flows, Internal Rate of Return (IRR) is more appropriate. For revenue analysis, CAGR is still the standard because revenue doesn't have interim "flows."

• How does CAGR relate to Rule of 72?

  The Rule of 72 is a quick approximation: divide 72 by your growth rate to estimate how many years it takes to double. At 24% CAGR, doubling takes approximately 72/24 = 3 years. At 36% CAGR, approximately 72/36 = 2 years. This rule is handy for quick mental math in meetings but becomes less accurate at very high growth rates (above 50% CAGR).

• Should I use CAGR or IRR for investment decisions?

  Use CAGR when comparing the overall growth of a metric (revenue, users, market size) from one point to another. Use IRR when evaluating investments with multiple cash flows over time (like annual dividends or operating profits). For sales and revenue analysis, CAGR is almost always the right choice. For evaluating capital investments or projects, IRR provides more complete picture.
