Frequently Asked Questions
How is stock profit calculated?
Profit = (Sell Price × Shares - Commission) - (Buy Price × Shares + Commission). This is your gross profit before taxes.
What about taxes on stock profits?
Short-term gains (held under 1 year) are taxed as ordinary income. Long-term gains (over 1 year) get preferential rates of 0%, 15%, or 20%.
What about dividends?
This calculator covers trading profit only. Dividends received during your holding period would add to your total return.
Are commissions still a factor?
Most major brokers (Fidelity, Schwab, Robinhood) now offer $0 commission stock trades. Options and some other products may still have fees.
Is the Stock Profit Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
