Rate of Return Calculator
Use this calculator to find your total return, annualized return (CAGR), and inflation-adjusted annual return.
What is a rate of return?
Rate of return is the percentage gain or loss on an investment over a period of time. It answers a simple question: “How hard did my money work?” Whether you are evaluating a stock portfolio, index fund, real estate investment, or side-business capital, rate of return helps you compare results in a consistent way.
The challenge is that one number can mean different things depending on the formula. A 30% return over six years sounds great, but how does that compare with 30% in two years? That is why investors use both total return and annualized return.
The key return formulas
1) Total Return
Total return measures overall gain or loss from start to finish.
2) Annualized Return (CAGR)
Annualized return, often called CAGR (Compound Annual Growth Rate), converts your performance into an equivalent yearly growth rate. This is usually the better comparison metric when the time periods are different.
3) Real Return (Inflation-Adjusted)
Nominal returns can overstate progress. If your portfolio returns 7% but inflation is 3%, your real growth in purchasing power is much lower.
Why annualized return matters
Consider two investments:
- Investment A grew from $10,000 to $12,000 in 2 years.
- Investment B grew from $10,000 to $12,000 in 5 years.
Both show a 20% total return, but the annualized growth is very different. CAGR reveals the speed of growth and gives you an apples-to-apples comparison.
How to use this calculator
- Starting Value: What you initially invested.
- Ending Value: What the investment is worth now.
- Time Period: Total years held (can include decimals, like 3.5).
- Inflation Rate (optional): Your estimated average annual inflation.
After you click Calculate Return, the tool shows:
- Total return percentage
- Dollar gain/loss
- Annualized return (CAGR)
- Real annual return (if inflation is entered)
- Ending value multiple (e.g., 1.65×)
Common mistakes when calculating returns
Ignoring time
A high total return over a very long period may actually be mediocre annual growth.
Forgetting inflation
If inflation is elevated, nominal returns can be misleading. Real returns tell the true story of purchasing power.
Comparing unlike investments
Compare investments using the same method and roughly similar risk. A guaranteed bond and a high-volatility stock are not direct substitutes.
What this calculator does not include
This simple calculator assumes a single starting amount and a single ending amount. It does not model:
- Regular contributions (monthly deposits)
- Irregular cash flows
- Taxes, fees, or dividends separated from price growth
- Internal Rate of Return (IRR) calculations
If you make frequent deposits or withdrawals, you may need a money-weighted return or IRR calculator for accuracy.
Practical interpretation guide
- Negative CAGR: Capital shrank over the period.
- 0% to 4% CAGR: Conservative or low-growth performance.
- 5% to 8% CAGR: Common long-term equity index range (historically, not guaranteed).
- 9%+ CAGR: Strong growth, but check volatility and risk level.
Returns are only one part of the picture. Always consider risk, drawdowns, diversification, and your timeline before making investment decisions.
Final thoughts
A rate of return calculator is a quick way to evaluate whether your money is growing fast enough for your goals. Use total return to see overall performance, CAGR to compare across time, and real return to understand your true wealth growth after inflation.
