Tax on stock profits
In the US, shares held for more than one year are taxed at long-term capital gains rates of 0%, 15% or 20% depending on your income. Shares held a year or less are short-term and taxed as ordinary income. Losses can offset gains, and up to $3,000 of net losses a year can offset other income.
If you sell at a loss and buy the same or a substantially identical security within 30 days before or after, the wash-sale rule disallows the loss for now. This calculator gives an estimate, not tax advice.
Several purchases at different prices
If you bought in stages, use your average cost per share: total dollars spent divided by total shares. Your broker’s default method for tax lots is usually first in, first out unless you choose otherwise.
Questions people ask
How do I calculate profit on a stock?
Multiply the shares by the difference between sell and buy price, then subtract fees. 100 shares bought at $50 and sold at $65 is a $1,500 profit, a 30% return.
How do I calculate the percentage gain or loss?
Divide the profit by what you paid. 40 shares bought at $212 and sold at $187 is a $1,000 loss on $8,480, or −11.79%.
What price do I need to sell at to break even?
Your total cost plus the selling commission, divided by the shares. 500 shares at $12.40 with a $5 commission each way break even at $12.42.
