Based on our analysis of thousands of consumer financial profiles, the most common mistake people make is focusing solely on the interest rate without considering total loan cost, fees, and repayment flexibility. Always compare the APR — not just the rate — and read the fine print on prepayment penalties before signing.
Commissions and Fees
When it comes to commissions, both Fidelity and Interactive Brokers offer $0 commissions for online US stock, ETF, and options trades. This makes them highly competitive for the average investor. However, differences emerge in other areas:
- Fidelity: Generally offers $0 commissions on US stocks and ETFs. Options contracts are $0.65 per contract. Mutual funds can have transaction fees, though many Fidelity funds are commission-free.
- Interactive Brokers: Offers two pricing structures: IBKR Lite and IBKR Pro. IBKR Lite provides $0 commissions on US stocks and ETFs, similar to Fidelity. IBKR Pro, designed for active traders, offers lower margin rates and advanced features but charges commissions on a per-share or fixed basis for various asset classes, which can be more cost-effective for high-volume traders. International stock commissions vary by country but are generally very competitive.
Winner: It's a tie for basic US stock/ETF trading. IBKR Pro wins for active traders and international trading due to its highly competitive, often lower, per-share commissions and superior margin rates.
Trading Platforms and Tools
