This ROI calculator computes net profit, percentage return on investment, and annualized rate of return based on your initial investment, final value, and holding period. It's designed for investors evaluating stock or real estate performance, small business owners assessing whether a project paid off, and anyone comparing the profitability of different investments on an apples-to-apples basis. Enter your initial investment amount, the final or current value, and optionally the time held, and the calculator instantly shows your net profit, overall ROI percentage, and annualized return so you can compare it against other opportunities. Understanding annualized return is especially useful because it normalizes results across investments held for different lengths of time.

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.
