Stock Trading Fee Comparison: Brokerage Fee Structures and Cost Reduction Strategies

One of the often overlooked factors in stock investing is the stock trading commission fees. Many investors tend to focus solely on returns and ignore the cumulative impact of trading fees, but in reality, trading commissions significantly affect long-term investment profits. In this article, we will examine the components of stock trading fees, compare fees across different securities firms, and explore practical ways to reduce these costs.

Various Fees Incurred During Stock Trading

The costs borne by investors when buying and selling stocks are more complex than they seem. It’s not just the brokerage commission; additional fees paid to the exchange and settlement agencies, as well as currency exchange costs when trading overseas stocks, are also included.

For domestic stock trading, investors pay brokerage commissions to securities firms and fees to the Korea Exchange and the Korea Securities Depository. Generally, domestic stock trading fees are lower compared to overseas stocks.

Trading foreign stocks involves a more complex fee structure. In addition to brokerage commissions, currency exchange fees are incurred, and for U.S. stocks, fees from the U.S. Securities and Exchange Commission and the Financial Industry Regulatory Authority are also added. The typical online trading fee for major securities firms for U.S. stocks is around 0.25%.

2025 Status of Stock Trading Fees at the Top 5 Securities Firms

Fee structures vary by securities firm, and even within the same firm, different fees apply depending on the trading platform and transaction amount. Let’s look at the current fee structures of major securities firms.

Mirae Asset Securities charges 0.136% for domestic stock trading and 0.25% for overseas stocks. They are running a promotion where new and dormant customers opening a non-face-to-face direct account can trade domestic and U.S. stocks online free of charge for 90 days.

Korea Investment & Securities has a domestic stock trading fee of 0.147% and an overseas stock trading fee of 0.25%. They offer a 3-month free U.S. stock trading benefit for new and dormant customers.

Samsung Securities charges 0.147216% plus 1,500 KRW for transactions under 10 million KRW. Overseas stock trading fees are 0.25%, and new or dormant customers with non-face-to-face accounts can enjoy a 3-month exemption from U.S. stock trading fees.

Kiwoom Securities has different fees depending on the trading platform; for example, trading through HeroMUN4, domestic stock trading fees are as low as 0.015%. Overseas stock trading fees are 0.25%, and they run a 3-month free U.S. stock trading event for new and dormant customers with non-face-to-face accounts.

Shinhan Investment Corp. sets a fee of 0.1391639% plus 2,000 KRW for transactions under 30 million KRW. Overseas stock trading fees are 0.25%, and new or dormant customers with non-face-to-face accounts can enjoy a 1-year exemption from U.S. stock trading fees.

The Actual Impact of Trading Fees on Final Returns

Trading commissions are not just transaction costs; they are a crucial variable that influences long-term investment returns. Due to compound effects, even small differences in fees can lead to substantial profit gaps over time.

Suppose you start with 1 million KRW and make 10 trades, each yielding a 10% return. If the fee is 0.1%, the final amount would be approximately 2.57 million KRW; at 0.2%, about 2.54 million KRW, resulting in roughly a 30,000 KRW difference. As the investment amount and number of trades increase, this gap grows exponentially.

An even more significant point is the cumulative effect of fixed fees. For example, Samsung Securities’ fixed fee of 1,500 KRW per trade adds up to 150,000 KRW after 100 trades. For small-scale day traders, such fixed fees can substantially erode net returns.
