Results
What This Means
→ This example shows an investment that grew from $50,000 to $67,500 over 5 years—a total return of 35%.
→ The annualized return (6.2% per year) is lower than the total return (35%) because it accounts for the time involved. This is more useful for comparing against other 5-year investments.
→ The $17,500 gain is the actual dollars earned. This is valuable context—you know exactly how much your money grew in absolute terms.
→ In context: if this period saw average stock market returns of ~10% annually, this 6.2% return underperformed. If it matched average bond returns (~5% annually), it outperformed slightly.

Understanding Investment Returns
Investment return measures how much money you've made (or lost) on your investment, expressed as a percentage of what you initially invested. This calculator helps you calculate your return and compare investment performance.
Why Investment Returns Matter
Investment returns help you:
- Evaluate performance — Are your investments beating inflation and other benchmarks?
- Compare options — Which investment performed better relative to risk?
- Track goals — Are you on pace to reach retirement or savings targets?
- Tax planning — Knowing your returns helps identify tax-loss harvesting opportunities
Types of Returns
Realized return: Money you actually received (or lost) when you sold or exited an investment.
Unrealized return: Gains or losses on investments you still own (also called "paper gains/losses").
Total return: Includes both investment appreciation and any dividends or income distributed.
Annualized return: Return expressed as a yearly percentage, useful for comparing investments of different durations.
The ROI Formula
Return on Investment (ROI) is calculated as:
ROI = (Final Value - Initial Value) / Initial Value × 100
For example, if you invest $10,000 and it grows to $12,500: ROI = ($12,500 - $10,000) / $10,000 × 100 = 25%
Important Considerations
Market context: A 10% return in a year when the market averages 20% is actually underperformance. Compare your returns to relevant benchmarks (S&P 500, bond indices, etc.).
Time frame: Returns over different time periods can paint very different pictures. A 5-year return is more meaningful than a 1-month return for evaluating true investment performance.
Risk: Higher returns often come with higher risk. A 30% return from a concentrated bet in one stock carries far more risk than a 10% return from diversified index funds.
Fees: Investment fees significantly impact returns. A fund returning 8% with 2% annual fees really gives you 6%. Over decades, fee differences compound dramatically.
Taxes: Returns on taxable accounts are reduced by capital gains taxes. Tax-advantaged accounts (401k, IRA) don't have this drag.
Historical Returns by Asset Class (Long-term averages)
- Stock market (S&P 500): ~10% annually
- Bonds: ~4–6% annually
- Real estate: ~3–5% annually
- Inflation: ~2–3% annually (your money needs to beat this)
- Savings accounts/CDs: Currently 4–5% (varies with rates)
Individual results vary significantly year to year.
Return Expectations
When investing, remember:
- Inflation matters: 5% returns when inflation is 4% means only 1% real growth
- Volatility is normal: Markets have bad years; judge performance over 5–10+ years
- Diversification reduces risk: Spreading money across asset classes smooths returns
- Time is your advantage: Longer time horizons allow you to weather volatility
Frequently Asked Questions
This depends on risk and benchmarks. Stock market averages ~10% historically. Bond market averages ~4–5%. Your return should match or exceed relevant benchmarks for your investment type. A 5% return on a risky individual stock is poor; a 5% return on bonds is solid. Compare apples to apples.
