Frequently asked questions
What is a good ROI?
A good ROI depends on risk, time horizon, and what you compare it against. A strong return in one asset class may be average in another.
How is ROI calculated?
Basic ROI measures profit divided by the original investment. It is useful for a fast comparison, though it does not capture volatility or risk.
Annualized vs total return?
Total return looks at the whole gain over the entire holding period. Annualized return converts that result into an average yearly growth rate.
How should I compare investments?
Use the same time frame, include fees and taxes where possible, and compare to an appropriate benchmark rather than evaluating performance in isolation.
Do fees matter?
Fees reduce net return directly. Even small annual fees can compound into a large drag over time.
What about taxes?
Tax treatment can change the real return you keep. Different accounts and assets may have different tax consequences.
