CAGR Calculator Guide
This CAGR calculator instantly computes the compound annual growth rate for any values over any time period. CAGR is the most widely used metric for measuring consistent growth over time, whether you are analyzing investment returns, business revenue, or any other metric that changes over years.
Unlike simple average growth rates, CAGR accounts for compounding effects and provides the equivalent constant annual rate that would produce the observed total growth. It is the standard for investment performance reporting and business growth analysis.
- 1Total Growth = ($14,000 - $5,000) / $5,000 = 180%
- 2CAGR = ($14,000/$5,000)^(1/7) - 1
- 3CAGR = (2.8)^(0.1429) - 1 = 15.87%
- 4Growth Multiplier = 2.8x in 7 years
- 5Doubling Time = 72 / 15.87 = 4.5 years
- 6Projected value in 5 more years = $14,000 × (1.1587)^5 = $29,327
CAGR Growth Projection Table
| CAGR | 5 Years | 10 Years | 20 Years | 30 Years |
|---|---|---|---|---|
| 5% | $12,763 | $16,289 | $26,533 | $43,219 |
| 8% | $14,693 | $21,589 | $46,610 | $100,627 |
| 10% | $16,105 | $25,937 | $67,275 | $174,494 |
| 12% | $17,623 | $31,058 | $96,463 | $299,600 |
| 15% | $20,114 | $40,456 | $163,665 | $662,118 |
| 20% | $24,883 | $61,917 | $383,376 | $2,373,763 |
How to Use the CAGR Calculator
- CAGR works for any metric: revenue, earnings, users, GDP, portfolio value
- Always use consistent time periods: start and end at the same point in cycles
- CAGR over 10+ years is more reliable than 1-3 year CAGR
- Very high CAGR (30%+) is rarely sustainable for long periods
- Use CAGR with standard deviation for complete risk-return analysis
Businesses use CAGR to set realistic growth targets and projections. If your revenue CAGR has been 15% for the past 5 years, a 15% forward projection is more defensible than a sudden jump to 30%. Investors and lenders expect growth projections aligned with historical CAGR.
CAGR vs. Average Annual Return: The Critical Difference
Many investors confuse CAGR (Compound Annual Growth Rate) with simple average annual return, but they tell very different stories. If an investment gains 50% one year and loses 33% the next, the simple average is 8.5% per year. But the CAGR is 0% — because you end up exactly where you started ($100 → $150 → $100.50 ≈ $100). CAGR is the more honest measurement because it reflects the actual ending value of your investment. It is the constant annual growth rate that would take you from the beginning value to the ending value over the same period. Always use CAGR when evaluating investments, mutual funds, or business growth.
The S&P 500's 10-year CAGR has averaged around 10-12% historically, though this varies significantly by the start and end dates chosen. From 2013-2023, the S&P 500 CAGR was approximately 11.5%. Individual stocks often have much higher or lower CAGRs. Apple's 10-year CAGR from 2013-2023 was approximately 26%, while traditional industries like utilities averaged 6-8%. CAGR is also used to evaluate business metrics: revenue CAGR, earnings CAGR, and customer growth CAGR are standard measurements for comparing companies and valuing businesses.
Using CAGR for Investment Goal Planning
CAGR is especially useful for projecting the future value of investments or reverse-engineering the required return to reach a financial goal. If you have $50,000 today and need $200,000 in 10 years, the required CAGR is (200,000/50,000)^(1/10) - 1 = 14.9% annually. This is above historical stock market averages, telling you either to invest more upfront, extend the timeline, or accept lower expectations. CAGR calculations help make abstract goals concrete and measurable, which is why financial planners use them to build retirement and wealth projections.
A quick shortcut: divide 72 by the CAGR to estimate how many years it takes to double your money. At 6% CAGR, money doubles in 12 years. At 10% CAGR, in 7.2 years. At 12% CAGR, in 6 years. This rule works for rates between 2-30% and is accurate within 1-2%. It is a powerful mental model for comparing investment options and understanding the impact of fees.
