What this calculator tells you

A positive result is a gain and a negative result is a loss relative to the total cost basis.

Formula and assumptions

Formula: Profit = (sell price − buy price) × shares − fees. Return = profit ÷ (buy price × shares + fees) × 100.

Assumptions

  • All shares are bought and sold at the entered prices.
  • The fees field includes all transaction costs; dividends and taxes are excluded.
