Frequently Asked Questions about ROI Calculator
What is the difference between total ROI and annualized ROI?
Total ROI shows overall return regardless of timeframe. Annualized ROI standardizes the geometric average annual return rate, allowing fair comparison between multi-year investments.
What is considered a good ROI?
An annual ROI above 7% to 10% is widely considered strong for equities, outpacing long-term inflation and risk-free benchmarks.
Does ROI account for transaction costs?
Standard simple ROI uses gross figures. True net ROI must deduct commissions, taxes, maintenance fees, and closing costs.
Can ROI be negative?
Yes. If an investment loses value and sells below original cost, ROI is negative, reflecting capital loss.
