Hong Kong Trading Fees Calculator — User Guide & Reference
Trading Hong Kong stocks means paying stamp duty, exchange fees, regulator levies, and commission on every transaction. This guide explains the layers, every input, and a worked example.
Disclaimer: This guide is provided for education only and does not constitute investment advice.
The layered fee structure
Hong Kong charges stamp duty on transaction value, plus exchange trading fees, SFC levies, and CCASS settlement charges on each side. On top sits your broker's commission, which varies by firm and is negotiable.
Why both legs matter
Most charges apply per transaction, so a full round trip pays them twice. Halving the cost in your head understates it by half. The total round-trip cost is what moves your break-even.
How the costs add up
Stamp duty is 0.1% of each side's value. The exchange trading fee, SFC levy, and CCASS charge are each a few basis points per side. Commission is your broker's rate, often with a minimum per order.
Worked example: HK$100,000 round trip
You buy HK$100,000 of a stock and sell the same amount. Stamp duty takes 0.1% on each side, so HK$200 total. The exchange fee, levies, and settlement charges add roughly another HK$50-60. If your broker charges 0.25% per side, commission is HK$500. The full round trip costs roughly HK$750, which is where break-even sits before any profit.
How to use the calculator
Enter the trade value and your broker's commission. Read the total for both legs. Compare it against the expected price move — if the move is smaller than the total fee percentage, the trade is arithmetically poor.
Common mistakes
The most common mistake is comparing HK fees to zero-commission US brokers and concluding HK is fine. Another is forgetting both legs pay. And treating the rates as fixed ignores that policy changes them.

Key concepts
Stamp duty

Broker commission
The fee charged by your broker, which varies by firm and is not a statutory charge.
Mistakes traders make
✗ Comparing HK fees to 'zero-commission' US brokers and concluding HK is fine
✓HK mandates stamp duty and exchange charges on every transaction. The full schedule, not the headline commission, is the real cost.
✗ Forgetting both legs pay the fees
✓Most charges apply per transaction, so a round trip pays twice. Halving the cost in your head understates it by half.
✗ Treating the statutory rates as fixed forever
✓Government and exchange rates change. Verify the current schedule before relying on a memorized figure.
When this tool fits — and when it does not
Use it when
- ✓Before a Hong Kong stock trade, to see the full round-trip cost.
- ✓Comparing the true cost of HK trading against other markets.
- ✓Checking whether a planned trade clears break-even after all fees.
Skip it when
- ✗Using a broker's commission alone as the total cost.
- ✗Relying on stale statutory rates without checking.
- ✗Trading frequently without recognizing how per-leg fees add up.
Practical tips that actually help
Total both legs, always
Buy-side and sell-side each carry charges. The round-trip total is the number that matters to your P&L.
Let fees set the minimum move
If the expected price move is smaller than the total round-trip fee percentage, the trade is arithmetically poor before it starts.
Recheck after any regulation change
Stamp duty and levies get adjusted by policy. A quick check beats a surprise on the statement.
