What is CAGR Calculator?

CAGR (Compound Annual Growth Rate) is a financial metric that measures the average annual growth rate of an investment or business over a specific period, taking into account the effect of compounding. Unlike simple linear growth calculations, CAGR provides a more accurate picture of investment performance because it accounts for the time value of money and reinvestment of returns. Kalkulab's CAGR Calculator serves as a tool for investors, business owners, and the general public to calculate the annual growth rate quickly and accurately...

CAGR (Compound Annual Growth Rate) Formula

CAGR = ((Ending Value / Beginning Value) ^ (1 / n)) - 1

    Investment value at the end of the period(e.g.: $200,000)
    💡 Calculate final investment result
  • BVBeginning Value
    Investment value at the start of the period(e.g.: $100,000)
    💡 Initial investment capital
  • nNumber of Years
    Investment duration in years(e.g.: 5 years)
    💡 Growth period
  • CAGRCompound Annual Growth Rate

How to Use the CAGR Calculator

Enter starting value, ending value, and time period for instant CAGR.

  1. 1

    Enter Starting Value

    Input investment or revenue at the start of the period (BV).

  2. 2

    Enter Ending Value

    Input value at the end of the period (EV).

  3. 3

    Set Time Period

    Enter number of years between start and end (n).

  4. 4

    Select Mode (Optional)

    Choose 'Calculate CAGR' or 'Projection' to forecast future value.

💡 Tip:

  • •Use CAGR to compare investments with different durations
  • •CAGR assumes steady annual growth (ignores volatility)
  • •Use projection mode for long-term financial planning

Examples

Example 1: Stock Growth Over 5 Years

Problem:

$100,000 grows to $175,000 in 5 years. CAGR?

  1. 1.CAGR = (175000/100000)^(1/5) − 1 = 11.86%
Result:11.86% per year

The investment grew at an average of 11.86% annually.

Example 2: Small Business Revenue

Problem:

Revenue $500,000 (2021) to $800,000 (2024). CAGR?

Solution:
  1. 1.3 years
  2. 2.CAGR = (800/500)^(1/3) − 1 ≈ 16.9%
Result:16.9% per year

Revenue grew 16.9% annually over 3 years.

Example 3: Retirement Goal

Problem:

$300,000 target $600,000 in 6 years. Required CAGR?

Solution:
  1. 1.CAGR = (600/300)^(1/6) − 1 ≈ 12.25%
Result:12.25% per year

Need at least 12.25% annual return to hit the goal.

Example 4: Comparing Two Investments

Problem:

A: $100k→$150k in 3 yrs. B: $200k→$320k in 5 yrs. Which is better?

Solution:
  1. 1.CAGR A = 14.47%
  2. 2.CAGR B = 9.71%
Result:Investment A (14.47% CAGR)

A has higher annualized return despite smaller nominal gain.
