Frequently Asked Questions
Return on Investment (ROI) measures the profit or loss from an investment relative to its cost. Formula: ROI = ((Return minus Cost) divided by Cost) times 100. Example: invest $1,000, earn $1,300 back: ROI = ((1300 minus 1000) divided by 1000) times 100 = 30%.
A good ROI depends on investment type and risk. The S&P 500 averages roughly 10% annual ROI. Real estate averages 8 to 12%. Savings accounts return 1 to 5%. Generally, higher returns require higher risk. A good ROI exceeds your opportunity cost and inflation.
