Frequently Asked Questions
How is stock profit calculated?
Stock profit = (Sell Price − Buy Price) × Shares − Total Fees. If you bought 100 shares at $50 and sold at $65 with $20 in fees, profit = (65−50)×100 − 20 = $1,480.
What are capital gains taxes on stocks?
In the US, short-term gains (held ≤1 year) are taxed at ordinary income rates. Long-term gains (held >1 year) are taxed at 0%, 15%, or 20% depending on income. Holding for over a year typically results in lower tax.
What is the break-even price after fees?
Break-even = Buy Price + (Total Fees / Number of Shares). If you paid $5,000 for 100 shares with $10 commission, break-even is $50.10/share. You need the stock to exceed this to profit.
