Frequently asked questions
Why annualise?
A 45% return over three years is not the same as 45% in one year. Annualising makes investments of different lengths comparable.
Does ROI include fees?
Only if you add them to the cost. For an accurate figure, include commissions, taxes and any carrying costs in the invested amount.
What do I need to enter into the ROI Calculator?
Just 3 values: amount invested, final value, holding period. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
