What Is an ROI Calculator?

An ROI Calculator computes the return on investment, showing the percentage gain or loss relative to the initial investment. It also calculates annualized ROI for comparing investments of different durations.

ROI is a universal metric used to evaluate investments in stocks, real estate, business projects, marketing campaigns, and more. Always compare ROI with the risk involved and alternative investment options.

ROI Formula

ROI = (Returns - Investment) / Investment × 100
Annualized ROI = (Returns / Investment)^(1/Years) - 1
Investment = Initial amountReturns = Final amountYears = Investment period

Frequently Asked Questions

What is ROI?
ROI (Return on Investment) measures the profitability of an investment. ROI = (Returns - Investment) / Investment × 100. It shows the percentage gain or loss relative to the initial investment.
What is a good ROI?
It depends on the investment type and risk. Stock market: 12-15% annualized. Real estate: 8-12%. Business: 20-30%. FD: 6-7%. Higher ROI usually means higher risk. Compare with risk-free rates (FD, bonds) as baseline.
ROI vs annualized ROI?
ROI shows total return over the entire period. Annualized ROI shows the equivalent yearly return, making it easier to compare investments of different durations. For 50% ROI over 3 years: Annualized = 14.47%.
How to calculate ROI for business?
ROI = (Net Profit / Investment) × 100. Include all costs (equipment, marketing, salaries) in investment. Include all revenue generated. For marketing campaigns: ROI = (Revenue from campaign - Campaign cost) / Campaign cost.
Can ROI be negative?
Yes, if returns are less than investment, ROI is negative. This means you lost money. Negative ROI indicates a poor investment decision or unfavorable market conditions. Always aim for positive ROI above inflation rate.
