Examples

100 shares bought at $50, sold at $75, $20 total commissions, $200 dividends over 3 years

1.Total cost = (100 Ã— $50) + $10 + $10 = $5,020
2.Sale proceeds = 100 Ã— $75 = $7,500
3.Net profit = $7,500 + $200 - $5,020 = $2,680
4.ROI = $2,680 / $5,020 = 53.4%
5.Annualized = (1.534)^(1/3) - 1 = 15.3%

Result: $2,680

Frequently Asked Questions

Return on Investment (ROI) is the net profit divided by the total cost, expressed as a percentage. It measures the efficiency of your investment.

Annualized return is the geometric average return per year over the holding period, allowing comparison across investments held for different time periods.

Commissions reduce your total return. Even small commissions of $10 per trade can add up, especially for frequent traders or small position sizes.
