Why is calculating trading fees important?
Trading fees directly reduce your profit. By calculating fees upfront, you can plan trades more accurately, avoid unexpected costs, and select the most cost-efficient brokers or trading instruments.
How do you calculate trading fees?
The formula is:
Total Fees = Flat Fees + (Trade Value × Percentage Fee)
Example: Buy 100 shares at $50, flat fee $10, 0.5% commission → Total Fees = $10 + (100×50×0.005) = $35.
Can the calculator handle different fee types?
Yes. It supports flat fees, per-trade fees, or percentage-based commissions. You can combine them for the most accurate cost calculation.

Net Profit = Gross Profit – Total Fees.
