How this calculator works
Gross versus net profit
Gross profit is the change in price multiplied by quantity. Net profit deducts the charges you enter. Taxes and broker-specific charges should be checked separately.
Use realistic prices
The expected sell price may not be the executed price. Slippage and bid–ask spreads matter, especially in less liquid securities.
Frequently asked questions
Can this result predict a trade?
No. It only applies a formula to your assumptions. Market prices, fills, fees and outcomes can differ.
Does TradeCalcZen store my values?
