ROI Calculator: Calculate Return on Investment
Use this guide with the ROI calculator above to estimate return on investment, net profit, annualized ROI, after-tax ROI, profit margin, break-even value, and payback period.
What Is an ROI Calculator?
An ROI calculator is a financial tool that estimates return on investment by comparing the profit or loss from an investment with the total amount invested.
ROI is commonly used to compare investments, business projects, marketing campaigns, real estate opportunities, product launches, and other financial decisions where cost and return matter.
How to Use This ROI Calculator

Return on Investment Formula
The standard ROI formula is:
Net profit is usually calculated by subtracting total cost from final value or revenue. A positive ROI means the investment made a profit, while a negative ROI means it resulted in a loss.
What This ROI Calculator Shows
This calculator gives a clear estimate of investment performance using common ROI metrics.
Return on Investment
The percentage return based on net profit and total investment cost.
Net Profit
The estimated dollar gain or loss after subtracting total costs.
Annualized ROI
An estimate of yearly return adjusted for investment period.
After-Tax ROI
An estimate of ROI after applying the selected tax rate to profit.
Profit Margin
Net profit as a percentage of final value or revenue.
Payback Period
An estimate of how long it may take to recover the original investment.
ROI Calculation Example
Suppose you invest $10,000, spend an additional $500, and the final value becomes $13,500.
Your total cost is $10,500. Your net profit is $3,000. ROI is calculated as $3,000 ÷ $10,500 × 100, which equals about 28.57%.
ROI vs. Annualized ROI
ROI shows the total return for the whole investment period. Annualized ROI adjusts that return into an estimated yearly rate, making it easier to compare investments with different time periods.
For example, a 30% ROI over one year is not the same as a 30% ROI over five years. Annualized ROI helps compare both more fairly.
When ROI Is Useful
ROI is useful when you want to compare the profitability of different options. It can be used for stocks, real estate, business campaigns, advertising, equipment purchases, product launches, and side projects.
However, ROI does not always show risk, timing, cash flow pattern, opportunity cost, or inflation. That is why ROI is often reviewed with other metrics like NPV, IRR, payback period, and profit margin.
