How It Works
Return on Investment (ROI) Formula
The standard formula for calculating Stock Return is:
ROI = (( (Sell Price * Qty) - Commissions + Dividends ) - (Buy Price * Qty) ) / Total Investment
Tax Implications
- Short-Term Gains: If you held the stock for one year or less, gains are taxed as ordinary income (10-37% depending on your bracket).
- Long-Term Gains: If you held for more than a year, you qualify for preferential rates of 0%, 15%, or 20%.
Frequently Asked Questions
How do dividends affect my return?
Dividends are cash payments from the company. They increase your
total return. This calculator adds dividends to your sale proceeds to calculate total
profit. Note: Qualified dividends may be taxed at different rates than ordinary dividends.
Why include commissions?
Commissions and fees increase your cost basis (when buying) and
reduce your proceeds (when selling), which lowers your taxable gain and your net ROI. It's
important to include them for an accurate calculation.
What if I sold for a loss?
If your proceeds are less than your investment, you have a capital
loss. This calculator will show a negative ROI. Capital losses can be used to offset capital
gains and up to $3,000 of ordinary income per year.
