Calculating Stock Returns Correctly
Many investors calculate returns incorrectly by ignoring taxes and commissions. Your true return = (Sale Proceeds − Purchase Cost − Commissions − Taxes) ÷ Purchase Cost. A stock bought at $45 and sold at $72 looks like a 60% gain — but after 15% long-term capital gains tax, the real return is 51%. Short-term (under 12 months) at the 22% bracket: only 47%. Commissions are minimal with modern brokers ($0 at most), but tax planning is essential. Explore tax-efficient strategies with our Capital Gains by State Calculator and track your portfolio with our Stock Average Calculator.
People Also Ask
How are stock profits taxed?
Held 12+ months: 0%, 15%, or 20% long-term capital gains rate. Under 12 months: ordinary income rate (10-37%). The 3.8% NIIT applies above $200K income.
What is annualized return?
Your total return adjusted for the time held. A 30% gain over 18 months = 20% annualized. This lets you compare investments held for different periods.
Can I offset gains with losses?
Yes — losses offset gains dollar-for-dollar. Up to $3,000 in excess losses can offset ordinary income. Remaining losses carry forward indefinitely.
