ROI Calculator - Return on Investment & Annualized ROI

How the ROI Calculator Works

1. 01Choose a currency and enter the total amount you invested.
2. 02Enter the total amount returned, including the original investment, such as the sale proceeds.
3. 03Optionally add the holding period in years to unlock annualized ROI.
4. 04Read the ROI percentage, net gain or loss, and the annualized rate that makes different investments comparable.

Judging Investments With ROI

ROI reduces any investment to one percentage: profit relative to what you put in. That simplicity is its strength and its trap. The plain ROI figure ignores time, so a 40% return looks identical whether it took two years or fifteen, and those are wildly different outcomes. Always enter the holding period when you know it; the annualized figure converts total return into a compound yearly rate you can compare against alternatives like an index fund or a savings account. Be complete about the invested amount: include purchase fees, transaction costs, taxes paid, and for property, renovation and holding costs. Likewise count all returns: sale proceeds plus dividends, rent, or other income received along the way. Omitting costs is the most common way people flatter their own results. For marketing and business uses, measure incremental profit rather than revenue: a campaign that cost 1,000 and produced 5,000 of revenue at a 30% margin returned 1,500 of profit, an ROI of 50%, not 400%. Finally, compare annualized ROI against what the money would have earned elsewhere; beating zero is not the bar, beating your alternative is.

When to Use the ROI Calculator

Use it after selling a stock, property, or business asset to measure the true result, before a purchase to test what sale price you would need for an acceptable return, and in business to evaluate marketing campaigns, equipment, or training spend. The annualized mode is essential whenever you compare investments held for different lengths of time, which is nearly always the real question.

Common Use Cases

• ·Measuring the true result after selling shares, crypto, or a rental property, including all costs.
• ·Comparing two past investments with different holding periods using annualized ROI.
• ·Evaluating a marketing campaign by entering ad spend and incremental profit.
• ·Testing required sale prices before buying an asset to reach a target return.
• ·Checking business equipment purchases against the profit they generated. → Profit Margin Calculator
• ·Projecting forward growth instead of measuring the past. → Compound Interest Calculator

Expert Tips

• ✻Always annualize when comparing investments of different lengths; total ROI alone systematically flatters long, mediocre holdings.
• ✻Include every cost in the invested amount, especially fees and taxes; omitting them is the most common self-deception in ROI math.
• ✻For business spend, compute ROI on incremental profit, not revenue, or a low-margin campaign will look far better than it is.
