ROI Calculator
Formula
ROI = (Return − Investment) ÷ Investment × 100
ROI measures the efficiency of an investment. Divide the profit by the original investment and multiply by 100.
How to use
- Enter the Amount Invested.
- Enter the Amount Returned.
- Read your ROI percentage and total profit.
Example
Invest $10,000 and get back $15,000: (15,000 − 10,000) ÷ 10,000 × 100 = 50% ROI, with a $5,000 profit. That means your money grew by half.
Frequently Asked Questions
What is a good ROI?
It depends on the investment type. Stocks average 7-10% annually. Real estate 8-12%. A 100%+ ROI doubles your money.
Can ROI be negative?
Yes, if the amount returned is less than the amount invested, ROI comes out negative, meaning you lost money. For example, putting in $10,000 and getting back $7,000 gives an ROI of -30 percent. A negative ROI is a clear signal the investment lost value over the period.
Should I include fees and taxes in my ROI calculation?
For an accurate picture, yes, you should use the net amount you actually received after trading commissions, fund fees, and taxes as your 'amount returned.' Ignoring these costs inflates your real ROI, sometimes significantly with frequent trading. The honest figure is what landed in your pocket compared to your total out-of-pocket cost.
