CAGR Calculation in Excel: A Complete Guide
The Compound Annual Growth Rate (CAGR) is a crucial financial metric. It shows the average yearly growth of an investment over a specific time period. Many businesses, investors, and financial analysts use Excel to calculate CAGR efficiently.
In this detailed guide, you will learn what CAGR is, how to calculate it in Excel, and why it matters. Let’s explore step-by-step methods, formulas, and examples to master CAGR calculation in Excel.
What Is CAGR?
CAGR (Compound Annual Growth Rate) is the rate at which an investment grows annually, assuming profits are reinvested at the same rate. It helps smooth out returns over a given time period, making it easier to compare different investments.
Why Is CAGR Important?
CAGR is important because:
- It provides a consistent annual growth rate.
- It simplifies comparing different investments.
- It helps evaluate the performance of stocks, funds, and businesses.
CAGR Formula
The formula for CAGR is: CAGR=(FVPV)1n−1CAGR = \left(\frac{FV}{PV}\right)^{\frac{1}{n}} – 1
Where:
- FV: Final Value (ending investment value)
- PV: Present Value (starting investment value)
- n: Number of years (investment period)
How to Calculate CAGR in Excel
There are multiple ways to calculate CAGR in Excel, including using formulas, built-in functions, and Excel templates. Let’s discuss each method in detail.
1. Using the CAGR Formula in Excel
Step 1: Open Excel and enter your investment data in columns.
- Column A: Year (start and end years)
- Column B: Investment Value (starting and ending amounts)
Example:
| Year | Investment Value |
|---|---|
| 2018 | 10,000 |
| 2023 | 18,000 |
Step 2: Use the Excel formula for CAGR. In a new cell, enter the following:
= (B2/B1)^(1/(A2-A1))-1
Step 3: Press Enter. The result will be displayed as a decimal.
Step 4: Format the cell as a percentage by clicking Home > Percentage.
2. Using the Excel Function: POWER()
Step 1: Use the POWER function to calculate CAGR.
=POWER(B2/B1,1/(A2-A1))-1
Step 2: Press Enter. Format the result as a percentage.
3. Using the Excel Function: RATE()
The RATE() function in Excel can also calculate CAGR.
Syntax:
=RATE(n, PMT, PV, FV)
Where:
- n: Number of years (A2 – A1)
- PMT: Payment amount (enter 0 if not applicable)
- PV: Present Value (-B1)
- FV: Final Value (B2)
Example Formula:
=RATE(A2-A1, 0, -B1, B2)
Press Enter and format the result as a percentage.
4. Using Excel Templates for CAGR Calculation
You can use Excel templates available online for CAGR calculations. These templates are pre-designed and include built-in formulas for calculating CAGR automatically.
Example: Calculating CAGR in Excel
Investment Example:
- Starting Value (2018): $10,000
- Ending Value (2023): $18,000
- Investment Period: 5 years
Excel Formula:
=(18000/10000)^(1/(2023-2018))-1
Result: 12.46% CAGR
