ROI Calculator

ROI = ((Final Value - Initial Investment) / Initial Investment) x 100. A $10,000 investment ending at $15,000 yields 50% ROI.

Annualized ROI (CAGR) expresses returns as a constant per-year rate using ((Final/Initial)^(1/years) - 1) x 100 — useful to compare investments held for different periods.

No, this is a clean two-point ROI. For recurring contributions use the Compound Interest or Investment Returns calculators.

There is no single "good" number, because ROI only means something next to the risk and the time involved. As a rough benchmark, the long-run stock market has returned roughly 7-10% per year, so a one-year ROI in that range is solid, while a 50% return earned over ten years is actually weak once you spread it across the years. A higher total ROI is not automatically better: doubling your money (100% ROI) in twenty years annualizes to only about 3.5% a year. That is why this calculator shows both the raw ROI and, when you add a holding period, the annualized rate. Enter your initial amount, final value, and the years above to see whether your return beats a reasonable yearly benchmark, then judge it against the risk you took.

Yes. Whenever your final value ends up below your initial investment, the net profit is negative and ROI drops below zero, signalling a loss. For example, putting in $10,000 and ending at $7,500 is a net loss of $2,500 and an ROI of -25%, meaning you got back 75 cents on every dollar. The annualized figure can be negative too, describing how fast the investment shrank each year. This tool flags a loss clearly with a red "Loss" badge and red figures so you never misread a minus sign, and the investment multiple falls below 1.00x to confirm your money contracted. Enter your real starting and ending amounts above and the calculator will show the exact percentage and dollar loss, which you can copy or export for your records.

They describe the same outcome from two angles. ROI is the percentage gain or loss relative to what you put in, calculated as ((Final − Initial) / Initial) × 100. The investment multiple is simply Final divided by Initial, expressed as an "x" figure showing how many times your money grew. The two are linked: a 50% ROI is a 1.50x multiple, a 100% ROI is 2.00x (you doubled your money), and a break-even outcome is exactly 1.00x with 0% ROI. Multiples feel intuitive for big wins — saying "10x" is clearer than "900% ROI" — while percentages are easier for small or negative returns. This calculator shows both side by side under the Basic ROI tab, so enter your numbers above and read whichever framing communicates your result best.

Use annualized ROI whenever the two investments were held for different lengths of time, and total ROI only when the periods match. Total ROI ignores time, so a 40% return looks identical whether it took one year or eight — which makes side-by-side comparison misleading. Annualized ROI, the compound annual growth rate, collapses each holding period into a single per-year rate so they line up fairly. For instance, 40% over two years annualizes to about 18.3% a year, while the same 40% over eight years is only about 4.3% a year, revealing the first investment as far stronger. This tool computes both: leave the holding period at zero for a quick total ROI, or enter the years to unlock the annualized figure. Run each investment above and compare the annualized rates.

Treat the money you spent as the initial investment and the total value it generated as the final value, then read the ROI. For a marketing campaign, if you spent $4,000 and it produced $10,000 in attributable revenue, enter 4,000 as the initial amount and 10,000 as the final value to get a 150% ROI and a 2.50x return on your spend. The same approach works for a freelance project's costs, a piece of equipment, or a course. Keep in mind this is a clean two-point calculation — it does not subtract ongoing fees, taxes, or overhead, so for a true profit figure use your net revenue after those costs as the final value. Enter your spend and the value it returned above, then export the result as a CSV to drop into a report or budget comparison.
