Trading costs are a key factor affecting your investment return rate. Choosing the wrong broker may cause you to lose a lot of profits unknowingly. Next, we will deeply analyze the fee structures of these three brokers to help you make the most economical choice.
Commissions and platform fees are the most common trading costs you encounter. Their charging methods directly determine your fixed expenses per trade.
Interactive Brokers (IB) offers highly competitive commission plans. It is willing to attract high-frequency traders by lowering per-trade commissions, thereby profiting from huge trading volumes. You can choose “fixed” or “tiered” pricing based on your trading style.
Futu Securities and Tiger Securities mainly adopt package forms, combining commissions and platform fees. This model is simpler and clearer for beginners who trade infrequently.
To make it easier for you to compare intuitively, we have organized the following overview of US stock trading fees:
| Broker Platform | Commission Plan | Platform Fee Plan | Minimum Fee Per Trade |
|---|---|---|---|
| Interactive Brokers (IB) | $0.005 per share | None | $1.00 |
| Futu Securities (Futu) | $0.0049 per share | $0.005 per share | $0.99 |
| Tiger Securities (Tiger) | $0.0039 per share | $0.004 per share | $0.99 |
Special Notes:
- Tiger Securities offers 0 platform fee discounts for over 1500 funds on its platform and lifetime zero-commission activities for specific users, which is very attractive for beginners and fund investors.
- Although Interactive Brokers has a minimum commission, its tiered rate is extremely advantageous for professional investors with huge trading volumes, with commissions as low as $0.0005 per share.
If you plan to trade with leverage, margin rates will be an important cost you must consider. Lower rates mean lower costs for borrowing funds, effectively amplifying your potential returns.
In this aspect, Interactive Brokers demonstrates its huge advantage as a professional broker. Its margin rates are the lowest among the three brokers.
Interactive Brokers uses tiered hybrid rate calculation. For example, when you borrow over $1,000,000, the first $100,000 is charged at the first tier rate, and subsequent funds at a lower second tier rate. This structure is very friendly for large-fund users.
In comparison, Futu and Tiger’s margin rates are usually higher. If you are a trader who frequently uses leverage, choosing Interactive Brokers can save you a considerable amount of interest expenses annually.
For investors outside the US, the cross-border flow costs of funds are also not to be ignored. This mainly includes currency conversion and bank transfer links.
1. Currency Conversion
When you need to convert local currency (such as HKD, RMB) to USD for trading, the broker will charge a certain fee or add a spread to the exchange rate.
| Broker Name | Currency Conversion Fee/Spread |
|---|---|
| Interactive Brokers (IB) | Approximately 0.002% |
| Futu Securities (Futu) | Approximately 0.05% - 0.1% |
| Tiger Securities (Tiger) | No public data, usually references real-time rates with a certain spread |
From the data, it can be seen that Interactive Brokers has an absolute advantage in currency conversion, with costs almost negligible. If you need frequent large-amount currency conversions, IB is your best choice.
2. Deposit/Withdrawal Costs
Deposit and withdrawal refer to depositing funds into the broker account or withdrawing funds from the broker account. Traditional methods like wire transfer usually have high fees and long processing times.
Interactive Brokers allows you one free withdrawal per calendar month. Subsequent withdrawals after the first will be charged based on currency and method. Note that these fees do not include additional fees that your bank or intermediary bank may charge.
Futu and Tiger Securities usually process funds through cooperation with licensed banks in Hong Kong. Deposits are usually free, but withdrawals incur certain handling fees from the bank, generally between $15 and $50.
Cost Optimization Tips: Traditional wire transfer methods are not only expensive but also relatively cumbersome. You can explore using multi-currency electronic wallets or fintech services for transfers, which usually significantly reduce your deposit/withdrawal costs and shorten waiting times.
To help you more clearly understand the cost differences in real trading scenarios, we simulated two different types of investors and calculated their annual total trading costs.
Scenario One: Low-Frequency Value Investor
| Broker Platform | Per-Trade Fee (Commission + Platform Fee) | Annual Total Cost | Notes |
|---|---|---|---|
| Interactive Brokers (IB) | $1.00 | $12.00 | Trading commission below account management fee, difference to be paid |
| Futu Securities (Futu) | $0.99 | $11.88 | Simple and transparent fee structure |
| Tiger Securities (Tiger) | $0.99 | $11.88 | Simple and transparent fee structure |
Scenario Two: High-Frequency Active Trader
| Broker Platform | Per-Trade Fee (Commission + Platform Fee) | Annual Total Cost | Notes |
|---|---|---|---|
| Interactive Brokers (IB) | $1.00 | $520.00 | Trading commission far exceeds account management fee, no additional payment needed |
| Futu Securities (Futu) | $0.99 | $514.80 | Relatively fixed costs |
| Tiger Securities (Tiger) | $0.99 | $514.80 | Relatively fixed costs |
Conclusion Interpretation:
- For low-frequency traders, the annual costs of the three brokers are very close. Futu and Tiger have a slight advantage due to their simple charging models.
- For high-frequency traders, although Futu and Tiger seem superior under basic rates, don’t forget IB’s tiered commissions. When your monthly trading commissions exceed $10, IB’s account management fee will be fully offset. For users with extremely large trading volumes, IB’s tiered rates will make its total cost far lower than Futu and Tiger.

When you invest funds in a broker, platform security is the most important factor for you to consider. Strong regulation, client asset insurance, and advanced technical protection together form your fund safety net.
When choosing a broker, you must pay attention to its security. Regulatory licenses are the first line of defense for safety. A broker under strict regulation means its operations must comply with local laws and regulations, and client funds are protected accordingly.
Interactive Brokers, Futu Securities, and Tiger Securities are all registered with the US Securities and Exchange Commission (SEC) and are members of the Financial Industry Regulatory Authority (FINRA). This means their business activities in the US are strictly supervised. Taking Tiger Securities as an example, its business spans the globe and holds licenses in multiple major financial markets.
| Entity Name | Jurisdiction | Regulatory Body/License Type |
|---|---|---|
| US Tiger Securities, Inc. | United States | SEC registered broker, FINRA member, SIPC member |
| Tiger Brokers (Singapore) Pte. Ltd. | Singapore | Licensed and regulated by Monetary Authority of Singapore |
| Tiger Brokers (HK) Global Limited | Hong Kong | Hong Kong SFC licensed corporation (Types 1,2,4,5,9) |
| Tiger Brokers (AU) Pty Limited | Australia | Australian Securities and Investments Commission (ASIC) licensed |
In addition, the company’s background and strength are also worth attention. For example, Tiger Securities (UP Fintech Holding Limited) was listed on Nasdaq in 2019, with early investors including Interactive Brokers and Xiaomi, providing strong support for its stable operations.
In addition to institutional regulation, your account assets also enjoy additional insurance. SIPC (Securities Investor Protection Corporation) provides you with a key layer of protection.
What is SIPC Protection? If your broker unfortunately goes bankrupt, SIPC will intervene to protect your assets. It provides up to $500,000 compensation protection per client, including up to $250,000 for cash portion.
Since the US entities of Interactive Brokers, Futu, and Tiger are all SIPC members, the US stocks you hold through them and cash in the account enjoy this standard protection. This allows you to be more at ease facing extreme market risks.
In daily use, powerful technical measures can effectively prevent your account from being stolen. Two-factor authentication (2FA) is one of the most effective security methods currently.
At the same time, these brokers all use data encryption technology to protect the security of your personal information and trading data during transmission, ensuring your privacy is not leaked.
After a comprehensive comparison, we have organized the final summary and recommendations for you. Hope this table can help you quickly review the core features of the three brokers.
