Question 1

What is ROI and how is it calculated?

Accepted Answer

Return on Investment (ROI) measures how much profit or loss you made relative to your initial investment. The formula is: ROI = [(Final Value - Initial Investment) / Initial Investment] × 100. For example, if you invest $1,000 and it grows to $1,250, your ROI is 25%. A positive ROI means you made money, while a negative ROI means you lost money.

Question 2

What is annualized ROI and why does it matter?

Accepted Answer

Annualized ROI shows your average yearly return, making it easier to compare investments held for different time periods. For example, a 25% return over 5 years (4.6% per year) is very different from 25% in 1 year. The formula is: Annualized ROI = [(Final Value / Initial Investment)^(1/Years) - 1] × 100. This helps you compare a 2-year investment against a 10-year investment fairly.

Question 3

What is a good ROI percentage?

Accepted Answer

ROI benchmarks: Over 20% is excellent (outperforming most benchmarks), 10-20% is good (solid returns), 5-10% is moderate (beating inflation), 0-5% is low (barely keeping up with inflation), and below 0% is a loss. However, context matters - a "good" ROI depends on the asset class, time period, and market conditions. The S&P 500 historically averages about 10% annually.

Question 4

Should I include additional costs in my ROI calculation?

Accepted Answer

Yes, for an accurate ROI calculation you should include all costs: purchase price, fees, commissions, taxes, maintenance, and any other expenses. You should also include all income received like dividends, rent, or interest. The formula becomes: Total Investment = Initial Cost + Additional Costs, Total Return = Final Value + Income Received, ROI = [(Total Return - Total Investment) / Total Investment] × 100.

Question 5

How is ROI different from other investment metrics?

Accepted Answer

ROI is a simple percentage that shows your total return relative to what you invested. It's different from: (1) Absolute return (just the dollar amount gained), (2) IRR or Internal Rate of Return (accounts for timing of cash flows), (3) CAGR or Compound Annual Growth Rate (similar to annualized ROI but calculated differently), and (4) Total return (may include reinvested dividends). ROI is the most straightforward metric for comparing investment performance.

Question 6

Can I use this calculator for real estate investments?

Accepted Answer

Yes! For real estate, include: (1) Initial Investment = Purchase price + closing costs + renovation costs, (2) Additional Costs = Maintenance, property taxes, insurance over holding period, (3) Income Received = Total rental income collected, (4) Final Value = Sale price minus selling costs. This gives you a complete picture of your real estate investment return. For more detailed real estate analysis, check our Renovation ROI calculator.

Question 7

What should I do if my ROI is negative?

Accepted Answer

A negative ROI means you've lost money on the investment. Consider: (1) Is this a temporary paper loss or realized loss? Holding longer may allow recovery, (2) Compare to benchmarks - did the whole market decline? (3) Review your investment thesis - has something fundamentally changed? (4) Consider tax-loss harvesting if you need to sell at a loss, (5) Learn from the experience to improve future investments. Not every investment will be profitable, but understanding why helps you make better decisions.

Question 8

How do I compare multiple investments with different time periods?

Accepted Answer

Use annualized ROI to compare investments held for different lengths of time. A 50% return over 5 years (8.4% annualized) may actually be better than 40% over 2 years (18.3% annualized) depending on your goals. Our "Compare Multiple" mode lets you input several investments and see them side-by-side. Also consider risk - higher returns usually come with higher risk.
