Často kladené otázky
How do I calculate ROI percentage?
Subtract initial investment cost from final value, divide by initial cost, and multiply by 100. Example: ($150 - $100) / $100 = 0.50 × 100 = 50% ROI.
Can ROI percentage be negative?
Yes, if final investment value is lower than initial investment cost, ROI will be negative, indicating a financial net loss.
What is Annualized ROI?
Annualized ROI calculates geometric average annual return, allowing fair comparison of investments held over different time periods.
What is considered a good ROI percentage?
S&P 500 historical average annual ROI is ~10% (7-8% inflation-adjusted). Good commercial real estate ROIs range from 8% to 12%+.
Does basic ROI account for holding taxes or inflation?
Standard simple ROI does not account for taxes, fees, or inflation. Net ROI after expenses provides a more accurate metric.
