Interactive Brokers Fees & Spreads (2026)

Interactive Brokers Trading Costs Explained

Understanding Interactive Brokers's fee structure is essential before opening an account. The minimum spread starts at 0.2 pips, which is competitive compared to the industry. An additional commission of $0.005 per lot applies on certain account types.

For deposits, Interactive Brokers does not charge any deposit fees. Withdrawals are free of charge. Note that additional swap or overnight financing charges apply to leveraged positions held beyond market close, and an inactivity fee may be charged after prolonged periods of no trading.

When evaluating total trading costs, consider your typical trade frequency and position size. A broker with tighter spreads but a per-lot commission may be cheaper for large positions, while a spread-only model often works better for smaller or less frequent trades.
