What to include in stock profit calculation
Stock profit should account for more than purchase and sale price. Brokerage fees, taxes, and other transaction costs can reduce the actual return. This calculator estimates gain or loss after price movement and fees.
Use it before a trade for scenario planning or after a trade to review actual return. Ignoring costs can overstate profit, especially for smaller or frequent trades.
Formula or logic
- Profit or loss = Sale value - Purchase value - Trading costs
- Return = Profit or loss ÷ Invested cost × 100%
Example
If 100,000 is invested and the stock rises 8%, but total trading costs are 600, actual profit is not simply 8,000. The costs must be deducted.
Common questions
Should fees be included?
Yes. Brokerage fees, taxes, and other costs affect actual return, especially for small or frequent trades.
Is this investment advice?
No. It is only a calculation tool and does not recommend buying or selling any security.
Can it calculate losses?
Yes. Use a negative price change or a sale price lower than the purchase price to estimate loss and return.
