Annualized Return Calculator
Calculate the annualized return (CAGR) of your investments. Compare performance across different time periods, account for compounding, and make smarter investment decisions. Enter your initial investment, final value, and time period to get started.
What Is Annualized Return (CAGR)?
Annualized return, also known as the Compound Annual Growth Rate (CAGR), is the average annual return of an investment over a specified period, assuming the profits are reinvested at the end of each year. It smooths out the volatility of annual returns and provides a clear picture of an investment's performance over time.
The annualized return formula is:
Annualized Return = (Final Value / Initial Investment)1 / Years − 1
Where:
Final Value = The ending value of the investment
Initial Investment = The original amount invested
Years = The number of years the investment was held
With additional contributions:
Adjusted Initial Investment = Initial Investment + (Additional Contributions / 2) [approximation]
This calculator also shows your total return (the overall percentage gain or loss), total gain/loss in currency, and the real return adjusted for inflation to give you a complete picture of your investment performance.
How Does the Annualized Return Calculator Work?
The calculator follows these steps:
- Step 1: Calculate the total gain = Final Value − Initial Investment − Additional Contributions
- Step 2: Calculate the total return = (Final Value / Net Investment) − 1
- Step 3: Calculate the annualized return (CAGR) = (Final Value / Net Investment)1 / Years − 1
- Step 4: Adjust for inflation to get the real return = ((1 + CAGR) / (1 + Inflation Rate)) − 1
The calculator also generates a growth chart showing how your investment value increases over time, assuming the annualized return is applied each year.

❓ Annualized Return Calculator FAQ
What is annualized return?
Annualized return (or CAGR) is the average annual return of an investment over a specific period, assuming profits are reinvested each year. It's the best way to compare investments with different time horizons.
What is the formula for annualized return?
The formula is: Annualized Return = (Final Value / Initial Investment)^(1 / Years) − 1. This calculator does the math for you automatically.
What is the difference between total return and annualized return?
Total return is the overall percentage gain or loss over the entire investment period. Annualized return is the average annual return that would produce the same total return if compounded each year.
What is a good annualized return?
A good annualized return depends on the type of investment and market conditions. Historically, the S&P 500 has returned about 10% per year on average. Higher returns typically come with higher risk.
How does compounding affect annualized return?
Compounding means that returns are reinvested, so you earn returns on your returns. The annualized return (CAGR) captures this effect, making it a more accurate measure of performance than a simple average.
What is the difference between CAGR and IRR?
CAGR assumes a single initial investment and a single final value. IRR (Internal Rate of Return) accounts for multiple cash flows over time, such as additional contributions or withdrawals. This calculator focuses on CAGR.
What is real return?
Real return is the return after adjusting for inflation. It shows the increase in your purchasing power. For example, if your nominal return is 8% and inflation is 3%, your real return is about 4.85%.
How do additional contributions affect annualized return?
Additional contributions increase the total amount invested, which can lower the annualized return if the final value doesn't increase proportionally. This calculator approximates the effect by adjusting the net investment.
What is the difference between annualized return and average return?
Average return is the arithmetic mean of annual returns, which doesn't account for compounding. Annualized return (CAGR) is the geometric mean, which accurately reflects the effect of compounding.
How do I use this calculator for my investments?
Enter the amount you originally invested, the current or ending value, and the number of years you held the investment. The calculator will show your annualized return, total return, and other key metrics.
What is the Rule of 72?
The Rule of 72 is a quick way to estimate how long it takes for an investment to double. Divide 72 by the annualized return (as a percentage) to get the approximate number of years. For example, at 8% return, it takes about 9 years to double.
What is the difference between nominal and real return?
Nominal return is the return without adjusting for inflation. Real return is the nominal return minus the inflation rate, representing the true increase in purchasing power.
Can annualized return be negative?
Yes, if the final value is less than the initial investment, the annualized return will be negative, indicating a loss on average each year.
How does the time period affect annualized return?
Longer time periods tend to smooth out volatility and provide a more stable measure of performance. Short-term returns can be more volatile and less meaningful for comparison.
What is the difference between annualized return and ROI?
ROI (Return on Investment) is the total return expressed as a percentage of the initial investment. Annualized return is the average annual return, which allows for comparison across different time periods.
