Frequently Asked Questions — ROI Calculator
What is ROI and how is it calculated?
ROI (Return on Investment) measures the gain or loss relative to the initial investment, expressed as a percentage. Formula: ROI = (Net Profit ÷ Initial Investment) × 100. A 50% ROI means you earned 50 cents for every dollar invested.
What is annualized ROI?
Annualized ROI normalizes returns over time so investments of different durations can be compared. Formula: Annualized ROI = ((1 + ROI/100)^(1/years) − 1) × 100. A 100% total ROI over 5 years equals about 14.9% annualized.
What is a good ROI?
A "good" ROI depends on the investment type and risk. Stock market average is roughly 7–10% annually. Real estate averages 8–12%. Higher-risk investments like startups may target 20%+ but with greater risk of total loss.
