Understanding Trading Costs
Trading costs can significantly impact your returns over time. Our calculator breaks down the three main cost components to help you make an informed decision.
Spreads
The difference between buy and sell price. This is the primary cost for most retail traders.
Commissions
Fixed fees per trade. Some brokers offer zero commissions but compensate with wider spreads.
Overnight Fees
Swap fees for holding positions overnight. These add up significantly for longer-term positions.
