Recently, many beginners have been asking me about how to calculate stock transaction fees, so I’ve organized the current market situation for everyone’s reference. To be honest, many people buy stocks without clearly thinking about how much the stock needs to rise to break even; understanding this pit is essential before trading to make it worthwhile.

First, let’s talk about the situation in Taiwan stocks. The costs involved in trading Taiwanese stocks are actually two parts: commission fees and transaction tax. The commission fee is 0.1425% of the transaction amount, and most brokerages offer discounts, usually around 50-60% of the original rate. The transaction tax is 0.3%, but it’s only charged when selling. For example, take Master Kong; if you buy one lot of stocks at 200 NT dollars, and the broker offers a 60% discount, then the purchase fee is 171 NT dollars. When selling, you pay 171 NT dollars in commission plus 600 NT dollars in transaction tax, so the stock needs to increase by 942 NT dollars to break even. That’s why I always say retail investors need to carefully calculate costs; don’t just look at the price change percentage.

Regarding Taiwanese brokerages, I’ve checked some options—Fubon, Yuanta, E.SUN Bank, and UnionPay are pretty good. Their commission discounts range from about 16.8% to 20%, and they often have account opening gifts. When choosing, besides considering the commission discount, you should also think about branch locations and customer service quality.

The situation in the US stock market is a bit more complicated. There are mainly two ways to trade US stocks in Taiwan: one is through Taiwanese broker’s cross-border agency trading, and the other is by directly opening an overseas brokerage account. For agency trading, the commission fee is usually between 0.25% and 1%, with minimum charges—Yuanta starts at $35 USD, Cathay Securities is a bit cheaper at $29 USD. Besides the commission, you also need to add transaction tax, system service fees, and other miscellaneous charges. So, when calculating stock transaction fees, you need to sum all these costs to understand the actual expense.

If you use an overseas broker directly, the good news is that most have eliminated stock trading commissions, which saves a lot for small traders. However, there are deposit and withdrawal fees, usually around $30 USD. Personally, I think for small investments, platforms like Mitrade that support NTD deposits and withdrawals are more convenient and have lower entry barriers.

Here’s a point many people overlook: if you’re doing short-term trading and frequently entering and exiting positions, you’ll accumulate a large amount of transaction fees. Instead of having your profits eaten up by fees in the stock market, consider CFD platforms. CFDs only charge spreads and overnight fees, regardless of how many trades you make, so you don’t have to worry about exploding transaction costs—especially suitable for high-frequency traders.

The factors affecting transaction fees are basically a few: different exchanges, different brokerages, different transaction amounts, and different trading frequencies. Large brokerages usually have higher fees but often run promotions; small trades might face minimum charges, and frequent trading can significantly increase costs. When choosing a trading method, you should decide based on your trading habits and capital size.

In short, before buying stocks, you must carefully calculate the stock transaction fees to ensure your profits can cover all trading costs. Otherwise, even the most promising market won’t help.
