Return on Investment (ROI) Calculator
Measure profitability, calculate capital efficiency, and determine annualized returns across business ventures, ad campaigns, and real estate.
Frequently Asked Questions
What is the formula to calculate Return on Investment (ROI)?
The standard ROI formula is: ROI (%) = ((Final Value of Investment - Initial Cost of Investment) / Initial Cost of Investment) * 100. Net Profit equals Final Value minus Initial Cost.
What is Annualized ROI and why is it important?
Annualized ROI accounts for the holding duration of an asset, allowing you to accurately compare investments held over different time periods (e.g. a 30% return over 1 year is vastly superior to a 30% return over 5 years).
What is considered a good ROI in business and marketing?
In digital marketing and paid advertising, a 5:1 ratio (500% ROI) is widely considered strong. For stock market investments, an annualized return of 7% to 10% (matching the historical S&P 500 average) is the baseline benchmark.
How ROI Is Calculated
ROI answers one question: for each dollar invested, how many cents of profit came back? The calculator shows three views of the same investment: total ROI, annualized ROI (per-year pace), and the investment multiple.
ROI = (Final value - Cost) / Cost x 100
Annualized ROI = ((Final / Cost)^(1/years) - 1) x 100
Multiple = Final value / Cost
Worked Investment Examples
Computed exactly as the calculator does:
| Investment | Net profit | Total ROI | Annualized ROI | Multiple |
|---|---|---|---|---|
| $1,000 to $1,500 in 1 year | +$500.00 | +50.00% | +50.00%/yr | 1.50x |
| $5,000 to $6,200 in 2 years | +$1,200.00 | +24.00% | +11.36%/yr | 1.24x |
| $10,000 to $12,000 in 3 years | +$2,000.00 | +20.00% | +6.27%/yr | 1.20x |
| $2,500 to $2,000 in 1 year | -$500.00 | -20.00% | -20.00%/yr | 0.80x |
Total ROI vs Annualized ROI: Why Time Matters
The same total return means very different things over different horizons:
| Scenario | Total ROI | Annualized ROI |
|---|---|---|
| $1,000 to $1,500 in 1 year | 50.00% | 50.00%/yr |
| $1,000 to $1,500 in 5 years | 50.00% | 8.45%/yr |
| $1,000 to $1,500 in 10 years | 50.00% | 4.14%/yr |
Computation for 5 years: (1500/1000)^(1/5) - 1 = 1.5^0.2 - 1 = 0.08447 = 8.45%/yr. Always compare investments on annualized ROI, never on totals alone.
Worked Example: $5,000 Growing to $6,200 in 2 Years
- Net profit: 6,200 - 5,000 = $1,200
- Total ROI: 1,200 / 5,000 x 100 = 24.00%
- Annualized ROI: (6,200/5,000)^(1/2) - 1 = 1.24^0.5 - 1 = 1.11358 - 1 = 11.36%/yr
- Multiple: 6,200 / 5,000 = 1.24x
Enter 5000, 6200, and 2 in the calculator above to confirm.

Frequently Asked Questions About ROI
Return on Investment: the profit of an investment as a percentage of its cost. ROI = (final value - cost) / cost x 100. A $5,000 investment that returns $6,200 has an ROI of 24%.
Subtract the initial cost from the final value to get net profit, divide by the initial cost, and multiply by 100. Example: ($6,200 - $5,000) / $5,000 x 100 = 24%.
Annualized ROI spreads the return evenly per year: ((final/cost)^(1/years) - 1) x 100. It matters because 50% over 1 year (50%/yr) and 50% over 5 years (8.45%/yr) are very different investments.
It depends on risk and time: the long-run US stock market returns roughly 7-10% per year. Compare any investment's annualized ROI against that benchmark and against its risk.
Yes. If the final value is below the cost, ROI is negative. A $2,500 investment returning $2,000 is a -20% ROI, a $500 loss.
Final value divided by cost (1.24x means you got back 1.24 times your money). Multiple and ROI carry the same information: 1.24x = +24% ROI.
Total ROI ignores time, which is why the calculator also shows annualized ROI. Always compare investments with annualized figures over the same horizon.
ROI divides profit by the investment cost; profit margin divides profit by revenue. A $1,200 profit on $5,000 cost is 24% ROI, but on $6,200 revenue it is a 19.35% margin.
No. ROI is a pure return number. Two investments with the same ROI can have very different risk, which is why ROI should never be the only decision metric.
It ignores time value of money, cash-flow timing, risk, and taxes. For multi-year projects with uneven cash flows, use NPV or IRR instead.
Taxes reduce the final value you keep, lowering after-tax ROI. The calculator shows pre-tax ROI; subtract expected taxes from the final value for an after-tax figure.
For a single lump-sum investment held N years, annualized ROI and CAGR are the same formula. CAGR is the term investors usually use for multi-year growth rates.
Only after converting to one currency. Exchange-rate moves change the final value in your home currency and therefore the ROI.
