The annualized rate of return is the constant yearly growth rate that turns a starting value into an ending value over a holding period. It is usually calculated as the compound annual growth rate: CAGR = (Ending Value / Beginning Value)^(1 / Years) - 1. In Excel, enter =(B2/A2)^(1/C2)-1 with the beginning value in A2, the ending value in B2, and the number of years in C2. For example, $10,000 growing to $13,310 in 3 years is a 10% annualized return.

What Is Annualized Rate of Return?
The annualized rate of return converts any investment return into a yearly equivalent. This matters because investments have different holding periods; a 6-month return cannot be compared directly with a 5-year return until both are annualized.
Why Annualize?
- Comparability: Compare stocks held for 2 years against bonds held for 7 years.
- Benchmarking: Market indices report annualized returns. Your investments should use the same standard.
- Goal setting: Financial plans use annualized returns to project future wealth.
- Risk assessment: Understanding annualized return alongside annualized volatility gives a complete risk-return picture.
Simple Example
You invest $10,000 and after 3 years you have $13,310. What is your annualized return?
The total return is 33.1%, but the annualized return is not simply 33.1% ÷ 3 = 11.03%. Because of compounding, the correct annualized return is calculated using the CAGR formula:
CAGR = (13,310 / 10,000)^(1/3) - 1 = 0.10 = 10%
Your investment grew at an annualized rate of 10% per year.
What Is CAGR?
CAGR stands for Compound Annual Growth Rate. It is the most common way to annualize returns because it accounts for compounding: returns in one period are reinvested and earn returns in later periods.
Key Characteristics of CAGR
- Smoothing effect: CAGR ignores year-to-year volatility and shows a single steady growth rate.
- Geometric average: Unlike arithmetic average return, CAGR reflects the actual compounded growth.
- End-point sensitive: CAGR only uses the beginning and ending values, making it sensitive to the specific start and end dates chosen.
CAGR vs. Average Annual Return
Consider an investment that returns +50% in Year 1 and -33.3% in Year 2:
| Year | Start Value | Return | End Value |
|---|---|---|---|
| 1 | $10,000 | +50% | $15,000 |
| 2 | $15,000 | -33.3% | $10,000 |
- Average annual return: (50% + (-33.3%)) / 2 = 8.35% — misleading because you actually ended up flat.
- CAGR: ($10,000 / $10,000)^(1/2) - 1 = 0% — accurately reflects that you made nothing.
This example shows why CAGR is superior to arithmetic average for measuring actual investment performance.
Annualized Rate of Return vs. Simple Return
| Feature | Simple (Total) Return | Annualized Rate of Return (CAGR) |
|---|---|---|
| Formula | (End - Start) / Start | (End / Start)^(1/n) - 1 |
| Accounts for compounding | No | Yes |
| Accounts for time | No | Yes |
| Comparable across periods | No | Yes |
| Best use | Short-term performance | Multi-year comparison |
| Example | "My stock returned 50%" | "My stock returned 14.5% per year" |
When to Use Each
- Simple return: Single-period analysis, quick performance check, positions held less than one year.
- Annualized return (CAGR): Multi-year performance evaluation, comparing investments, financial planning, reporting.
The CAGR Formula
The standard CAGR formula is:
CAGR = (Ending Value / Beginning Value)^(1 / Number of Years) - 1
Components
| Variable | Description | Example |
|---|---|---|
| Ending Value (EV) | Final investment value | $25,000 |
| Beginning Value (BV) | Initial investment value | $10,000 |
| n | Number of years | 5 |
| CAGR | Compound annual growth rate | 20.11% |
Calculation
CAGR = ($25,000 / $10,000)^(1/5) - 1
CAGR = (2.5)^(0.2) - 1
CAGR = 1.2011 - 1
CAGR = 0.2011 = 20.11%
This means the investment grew at an annualized rate of 20.11% over 5 years.
How to Calculate CAGR in Excel (Manual Methods)
Method 1: Direct Formula
The most straightforward way:
=(End_Value/Begin_Value)^(1/Years)-1
Example:
=(25000/10000)^(1/5)-1
Result: 0.2011 (format as percentage → 20.11%)
Method 2: Using the POWER Function
=POWER(End_Value/Begin_Value, 1/Years)-1
Example:
=POWER(25000/10000, 1/5)-1
Method 3: Using the RATE Function
Excel's RATE function can calculate CAGR when structured correctly:
=RATE(nper, pmt, pv, fv)
=RATE(5, 0, -10000, 25000)
Where:
- nper = Number of periods (5 years)
- pmt = 0 (no periodic payments)
- pv = -10000 (negative because it is an outflow)
- fv = 25000 (future value)
Result: 0.2011 (20.11%)
Method 4: Using LN and EXP
For mathematical precision:
=EXP(LN(End_Value/Begin_Value)/Years)-1
=EXP(LN(25000/10000)/5)-1
Comparison of Excel CAGR Methods
| Method | Formula | Complexity | Notes |
|---|---|---|---|
| Direct | =(EV/BV)^(1/n)-1 | Simple | Most intuitive |
| POWER | =POWER(EV/BV,1/n)-1 | Simple | Same result, function-based |
| RATE | =RATE(n,0,-BV,EV) | Medium | Built-in financial function |
| LN/EXP | =EXP(LN(EV/BV)/n)-1 | Medium | Mathematically elegant |
| MarketXLS | =CAGR(portfolio, period, amount) | Very Simple | Automated portfolio CAGR |
Annualizing Returns from Different Time Periods
What if your return is not measured in whole years? Here is how to annualize returns from various periods.
Monthly Return to Annual
=((1 + Monthly_Return)^12) - 1
Example: Monthly return of 1.5%:
=((1 + 0.015)^12) - 1 = 19.56%
Quarterly Return to Annual
=((1 + Quarterly_Return)^4) - 1
Example: Quarterly return of 4%:
=((1 + 0.04)^4) - 1 = 16.99%
Weekly Return to Annual
=((1 + Weekly_Return)^52) - 1
Daily Return to Annual
=((1 + Daily_Return)^252) - 1
Note: 252 is the typical number of trading days in a year.
Multi-Year Return to Annual
=((1 + Total_Return)^(1/Years)) - 1
Example: 85% total return over 4 years:
=((1 + 0.85)^(1/4)) - 1 = 16.62%
Annualization Reference Table
| Period | Formula | 2% Period Return → Annualized |
|---|---|---|
| Daily | (1+r)^252 - 1 | 548.3% |
| Weekly | (1+r)^52 - 1 | 180.1% |
| Monthly | (1+r)^12 - 1 | 26.82% |
| Quarterly | (1+r)^4 - 1 | 8.24% |
| Semi-annual | (1+r)^2 - 1 | 4.04% |
| 2-year total | (1+r)^(1/2) - 1 | 0.995% |
| 5-year total | (1+r)^(1/5) - 1 | 0.396% |
Using MarketXLS for Annualized Return Calculations
MarketXLS provides functions that simplify annualized return calculations and integrate directly with real market data.
The CAGR Function
MarketXLS includes a dedicated =CAGR() function for portfolio CAGR calculation:
=CAGR(portfolioRangeValues, period, initialAmount)
Formula documentation: CAGR
Parameters:
- portfolioRangeValues: A range containing stock symbols and their weights
- period: The analysis period (e.g., "5Y" for 5 years)
- initialAmount: The starting investment amount
Example:
=CAGR(A1:B5, "3Y", 100000)
Formula documentation: CAGR
Where A1:B5 contains:
| Symbol | Weight |
|---|---|
| AAPL | 0.30 |
| MSFT | 0.25 |
| JNJ | 0.20 |
| PG | 0.15 |
| VZ | 0.10 |
This returns the compound annual growth rate of the weighted portfolio over the specified period.
Pulling Historical Prices for Manual CAGR
If you prefer to calculate CAGR manually with real data, MarketXLS provides historical price data:
=GetHistory("AAPL", "2020-01-02", "2024-12-31", "Monthly")
Formula documentation: GetHistory
This returns historical prices that you can use to calculate beginning and ending values for the CAGR formula.
Getting Current and Historical Prices
=Last("AAPL") // Current price
=GetHistory("AAPL", "2019-01-02", "2024-12-31", "Monthly") // Historical data
Formula documentation: Last, GetHistory
Building an Annualized Return Dashboard
Create a comprehensive return analysis in Excel:
| Stock | Current Price | Formula |
|---|---|---|
| AAPL | =Last("AAPL") | Current market price |
| MSFT | =Last("MSFT") | Current market price |
| GOOGL | =Last("GOOGL") | Current market price |
For each stock, pull 5 years of history with =GetHistory(), then calculate CAGR manually:
=POWER(Last_Price / First_Price, 1/5) - 1
Or use the portfolio-level CAGR function for the entire portfolio at once:
=CAGR(A1:B5, "5Y", 100000)
Formula documentation: CAGR
Comparison of Return Calculation Methods
| Method | What It Measures | Accounts for Compounding | Accounts for Volatility | Best For |
|---|---|---|---|---|
| Simple Return | Total gain/loss | No | No | Quick single-period check |
| Average Annual Return | Arithmetic mean of yearly returns | No | Partially | Academic analysis |
| CAGR | Compounded growth rate | Yes | Smooths out | Multi-year performance |
| IRR | Return considering cash flows | Yes | Yes | Portfolios with deposits/withdrawals |
| Time-Weighted Return | Return independent of cash flows | Yes | Yes | Fund manager evaluation |
| Money-Weighted Return | Return considering timing of flows | Yes | Yes | Personal portfolio assessment |
When CAGR Is Not Enough
CAGR is excellent for simple buy-and-hold analysis, but it has limitations when:
- You make additional contributions or withdrawals during the period.
- You need to account for the timing of cash flows (use IRR instead).
- You want to understand year-by-year volatility (use standard deviation alongside CAGR).
Real-World Applications
Application 1: Comparing Stock Performance
Use annualized return to compare stocks over different holding periods:
// Stock A: Bought at $50, now at $120 after 4 years
=POWER(120/50, 1/4) - 1 // = 24.47% annualized
// Stock B: Bought at $30, now at $55 after 3 years
=POWER(55/30, 1/3) - 1 // = 22.37% annualized
Stock A had a higher annualized return despite a different holding period.
Application 2: Retirement Planning
If you need $1,000,000 in 25 years and can invest $200,000 today, what CAGR do you need?
=POWER(1000000/200000, 1/25) - 1 // = 6.65% annualized
You need an annualized return of 6.65% to reach your goal.
Application 3: Fund Performance Evaluation
Compare a mutual fund's CAGR against its benchmark:
// Fund CAGR
=POWER(Fund_End/Fund_Start, 1/Years) - 1
// Benchmark CAGR (using MarketXLS)
=GetHistory("SPY", "2019-01-02", "2024-12-31", "Monthly")
// Then calculate CAGR from first and last prices
Formula documentation: CAGR, GetHistory
Application 4: Business Revenue Growth
CAGR is not limited to investments. Companies use it to report revenue growth:
// Revenue grew from $5M to $12M over 4 years
=POWER(12/5, 1/4) - 1 // = 24.47% revenue CAGR
Limitations of CAGR
1. Ignores Volatility
CAGR does not tell you about the journey — only the destination. Two investments with the same CAGR can have vastly different risk profiles:
| Year | Investment A | Investment B |
|---|---|---|
| 1 | +10% | +40% |
| 2 | +10% | -20% |
| 3 | +10% | +30% |
| 4 | +10% | -10% |
| 5 | +10% | +25% |
| CAGR | 10% | ~10% |
Both have approximately the same CAGR, but Investment B was much more volatile. Always pair CAGR with a risk metric like standard deviation or maximum drawdown.
2. End-Point Sensitivity
CAGR is highly sensitive to the start and end dates. Choosing a market peak as the start date versus a market trough can drastically change the result.
3. Does Not Account for Cash Flows
If you add money to or withdraw money from your investment during the period, CAGR will not accurately reflect your personal return. Use Internal Rate of Return (IRR) instead.
4. Assumes Reinvestment
CAGR assumes all returns are reinvested. If you withdrew dividends instead of reinvesting them, the actual growth rate of your capital was different from the CAGR.
CAGR vs. Other Return Metrics
| Metric | Formula | Accounts for Cash Flows | Accounts for Compounding | Complexity |
|---|---|---|---|---|
| CAGR | (EV/BV)^(1/n)-1 | No | Yes | Low |
| IRR | Solve for r in NPV=0 | Yes | Yes | High |
| TWR | Product of sub-period returns | Removes cash flow effect | Yes | High |
| MWR | Similar to IRR | Yes, weighted by timing | Yes | High |
| Arithmetic Mean | Sum of returns / n | No | No | Very Low |
| Geometric Mean | (Product of (1+r))^(1/n)-1 | No | Yes | Medium |
Which Should You Use?
- Individual stock, buy-and-hold: CAGR
- Portfolio with regular contributions: IRR or MWR
- Fund manager comparison: TWR
- Quick approximation: Arithmetic mean (with caution)

Frequently Asked Questions
What is the annualized rate of return?
Annualized rate of return is a metric that expresses investment growth as a yearly percentage, regardless of the actual holding period. It allows investors to compare returns across different time frames on a standardized basis. The most common calculation method is CAGR (Compound Annual Growth Rate), which accounts for the effects of compounding.
How do I calculate annualized rate of return in Excel?
Annualized rate of return in Excel can be calculated using the formula =(Ending_Value/Beginning_Value)^(1/Years)-1. Alternatively, use =RATE(Years, 0, -Beginning_Value, Ending_Value) or =POWER(Ending_Value/Beginning_Value, 1/Years)-1. For portfolio-level analysis, MarketXLS offers the =CAGR() function.
What is the difference between CAGR and annualized return?
CAGR and annualized rate of return are often used interchangeably, but technically CAGR specifically refers to the compound annual growth rate — the geometric average return assuming reinvestment of all gains. Annualized return is a broader term that can include different calculation methods, though CAGR is the most common.
Why is CAGR better than average annual return?
CAGR is more accurate than average annual return because it accounts for compounding. Arithmetic average can be misleading — for example, returns of +100% and -50% average to +25% per year, but the actual result is 0% total return. CAGR correctly captures this: (1.0/1.0)^(1/2)-1 = 0%.
Can I calculate CAGR for a portfolio with MarketXLS?
Yes. MarketXLS provides the =CAGR(portfolioRange, period, initialAmount) function that calculates the compound annual growth rate for a weighted portfolio of stocks. Simply enter your stock symbols and weights in a range, specify the analysis period (e.g., "5Y"), and the initial investment amount.
What is a good annualized rate of return?
The S&P 500 has historically returned approximately 10% annualized (before inflation) or about 7% after inflation. Returns above 10% annualized over long periods are considered strong. However, higher returns typically come with higher risk. What constitutes a "good" return depends on your risk tolerance, investment goals, and the asset class.
Conclusion
Annualized rate of return is the standard measure for evaluating investment performance over time. CAGR — the compound annual growth rate — is the most reliable method because it accounts for compounding and normalizes returns across different time horizons. Whether you calculate it manually using Excel's POWER, RATE, or direct exponentiation formulas, or use the MarketXLS =CAGR() function for instant portfolio analysis, understanding this metric is fundamental to making informed investment decisions.
Pair CAGR with risk metrics like beta and standard deviation for a complete picture, and remember its limitations — particularly its sensitivity to start and end dates and its inability to account for intermediate cash flows.
