ROI Calculator
Calculate your Return on Investment (ROI) to measure the efficiency of an investment or compare the efficiencies of several different investments. Our calculator provides net profit, total return percentage, and annualized ROI.
ROI Comparison Scenarios
See how different returns look over time for a $10,000 investment:
| Final Value | Net Profit | Total ROI | Annualized (2 Years) |
|---|---|---|---|
| $11,000 | $1,000 | 10% | 4.88% |
| $12,500 | $2,500 | 25% | 11.80% |
| $15,000 | $5,000 | 50% | 22.47% |
| $20,000 | $10,000 | 100% | 41.42% |
What is ROI?
Return on Investment (ROI) is a financial metric used to evaluate the profitability of an investment. It measures the gain or loss generated on an investment relative to the amount of money invested. ROI is usually expressed as a percentage and is typically used for personal financial decisions, to compare a company's profitability, or to compare the efficiency of different investments.
What is ROI Good For?
- Investment Comparison: Easily compare the performance of different assets like stocks, real estate, or business ventures.
- Performance Tracking: Monitor how well your portfolio is performing over specific periods.
- Decision Making: Help decide whether to proceed with a new project or investment based on projected returns.
- Efficiency Measurement: Determine how effectively capital is being used to generate profit.
Limitations of ROI
While ROI is a powerful tool, it has some drawbacks:
- Time Factor: Basic ROI doesn't account for the duration of the investment (which is why Annualized ROI is important).
- Risk Ignored: ROI doesn't reflect the risk associated with an investment.
- Cash Flow: It doesn't account for the timing of cash flows during the investment period.
- Non-Financial Benefits: ROI only measures financial gain and ignores qualitative benefits.
ROI Formula
ROI = [(Final Value - Initial Cost) / Initial Cost] × 100
Annualized ROI Formula:
Annualized ROI = [(1 + ROI)1/n - 1] × 100
(where n = number of years)
Frequently Asked Questions
A "good" ROI depends on the asset class and the risk involved. For example, the S&P 500 historically returns about 7-10% annually. Real estate might target similar or higher returns depending on leverage.
Yes, if the final value of the investment is less than the initial cost, the ROI will be negative, indicating a loss.
ROI is the total return over the entire life of the investment. Annualized ROI shows the average yearly return, which allows you to compare investments held for different lengths of time.
Standard ROI calculations often use gross figures, but for a more accurate "Net ROI," you should subtract all costs, including transaction fees, maintenance, and taxes.
For rental property, ROI = (Annual Rental Income - Annual Expenses) / Total Investment Cost. You should also consider property appreciation when calculating total ROI upon sale.
