Enter what you put in and what you got back, set the holding period by dates or years, and get total ROI plus an annualized figure for comparison. ## How to use this ROI calculator 1. Enter the amount invested (your cost basis) and the amount returned (proceeds or current value). 2. Choose Use dates for a calendar holding period, or Use length to type in years directly. 3. Click Calculate and gain, ROI percentage, annualized ROI, and a pie chart all update at once. ## What is ROI? Return on investment is your net gain measured against what you put in. A 100% ROI just means the proceeds doubled your original stake. Part of why ROI is so popular is that it scales: $500 profit on a $500 investment looks identical, in percentage terms, to $5 million on $5 million. **Rate of return (ROR)** measures nearly the same thing, the difference is mostly in where you hear each term. ROI shows up more for projects, marketing campaigns, or one-off bets, while ROR is the language of portfolio reporting. Both compare gain to cost, and annualizing either one adjusts for time so a two-year flip and a ten-year hold can actually be compared. ### Basic ROI formula ### Annualized ROI Plain ROI does not care how long your money was tied up. Annualized ROI fixes that by compounding the growth rate down to a per-year figure, similar to CAGR: **t = years held** ### Worked example Invest $1,000 and get $2,000 back after roughly 4.5 years: - Gain: $1,000 - ROI: 100% - Annualized ROI: roughly 16.6% per year. Doubling your money in under five years takes serious yearly compounding to pull off. ### When ROI misleads ROI ignores risk, leverage, taxes, fees, and any cash flows that happened between purchase and sale. A 200% ROI on a heavily leveraged real-estate flip can carry more actual risk than a 12% annualized return sitting in a diversified index fund. Treat ROI as a first screen, then bring in time-adjusted metrics and total cost of ownership before you decide anything. ## Examples and use cases ### Real-world use cases - Stock sale: An investor buys shares for $3,200 and sells for $4,100 after 14 months. ROI shows the total gain; annualized ROI is what actually lets them compare it to index fund returns. - Equipment purchase: A small business spends $12,000 on machinery that brings in $18,000 in net proceeds after 3 years, and uses ROI to check whether the purchase cleared their hurdle rate. - Real estate flip: A flipper nets $45,000 on $150,000 invested over 8 months. The ROI number looks huge, but annualized ROI puts the short hold period into perspective. ## Frequently Asked Questions ### What counts as a good ROI? That depends heavily on the asset class and how much risk you took. Public equities have historically averaged high single-digit to low double-digit *annualized* returns over long stretches. Weigh any result against your opportunity cost and inflation before calling it good. ### What is the difference between ROI and annualized ROI? **ROI** is your total return over the whole period, full stop. **Annualized ROI** spreads that same growth across years so a short investment and a long one can actually be compared side by side. ### Can ROI come out negative? Yes. If the amount returned is less than what you invested, both the gain and the ROI go negative, which just means you lost money on the position. ### Does this calculator factor in fees or taxes? No. Enter amounts after fees and taxes if you want a net ROI, or before them for a gross estimate, just stay consistent with whichever you pick. ### How should I enter the holding period? Use calendar dates if you know the exact buy and sell days. If you only have a rough timeline, enter a fixed holding period in years or months instead. ```json [{"@context":"https://schema.org","@type":"Organization","name":"ShoutingNow","url":"https://shoutingnow.com/","logo":{"@type":"ImageObject","url":"https://shoutingnow.com/wp-content/themes/shoutingnow-theme/assets/images/logo.png"},"sameAs":["https://x.com/makani20","https://www.linkedin.com/in/makani20/","https://post-see.com"],"contactPoint":{"@type":"ContactPoint","contactType":"customer support","email":"support@shoutingnow.com","url":"https://shoutingnow.com/contact/"},"slogan":"Learn.
