Frequently Asked Questions
How is ROI calculated?
ROI = (Amount Returned − Amount Invested) ÷ Amount Invested × 100. A positive ROI means you made a profit; negative means a loss.
What does the multiplier mean?
The multiplier shows how many times your original investment was returned. A 2× multiplier means you doubled your money.
Does this account for time or taxes?
No. This is a simple ROI calculation. It does not factor in time period, inflation, or taxes.
What is a good ROI?
A 'good' ROI depends on the investment type and risk level. Stock markets historically return around 7–10% per year on average.
