Frequently asked questions
How is ROI calculated?
ROI = (Final Value − Initial Investment) / Initial Investment × 100, expressing your return as a percentage of the original amount invested.
What is annualized return and why does it matter?
Annualized return converts your total ROI into an equivalent yearly rate, making it easier to fairly compare investments held for different lengths of time.
What is a good ROI percentage?
A 'good' ROI varies widely by asset class and risk level; stock market long-term averages are often cited around 7-10% annually, but expectations should match the specific investment type.
Does this calculator include fees or taxes?
No, it calculates ROI based purely on the investment amounts you enter; fees, commissions, and taxes should be factored in separately for a fully accurate picture.
Can I use this ROI calculator for real estate investments?
Yes, it works for any investment type where you can input an initial cost and a final or current value, including real estate.
