About Stock Profit / Loss Calculator
Short vs long-term gains (US)
Long-term: held > 1 year, taxed at 0% / 15% / 20% (depending on income). Short-term: held ≤ 1 year, taxed as ordinary income (up to 37%). Holding past one year often makes a big tax difference.
Wash sale rule (US)
If you sell at a loss and buy substantially identical security within 30 days (before or after), the loss is disallowed. Plan tax-loss harvesting around this rule.
What this ignores
Dividends received (add to total return). Taxes on dividends (qualified vs non-qualified). State taxes on capital gains. Reinvestment of partial sale proceeds.
