Portfolio Calculators
Compare overseas-stock fees and FX discounts across 10 brokers and calculate your annual cost based on your own trading.
Typically 1% versus the base exchange rate
The securities transaction tax on selling Korean stocks (0.20%) is the same at every broker, so it is excluded from the comparison.

Costs are returns too
Overseas stocks come with both trading commissions and FX costs. The more often you trade, the more your choice of broker directly affects your returns.
Enter your average monthly overseas and domestic trading volume and FX amount.
Calculates one year of costs using each broker's standard fees and confirmed FX discount rates.
Promotions change frequently. Check the verification date in the table together with each broker's notices.
Exchange charges such as the US SEC fee and related-agency fees are excluded for simplicity. Since financial regulators urged restraint in overseas-investment marketing in December 2025, new overseas-stock fee promotions have dropped sharply. Accounts already enrolled in an earlier promotion may keep their preferential terms.
At the time of checking, most overseas-stock promotions available to new customers had been discontinued, so the comparison uses standard fees. Promotion details are noted separately in the table descriptions.
For brokers where it is not officially confirmed, the calculation uses the assumed value you entered (default 90%) and marks it as 'assumed' in the table. Check the actual discount rate in the broker's app.
Broker fees and promotions change frequently. There may be changes after the verification date shown at the top of the table.
Results are estimates based on your inputs and simplified assumptions, and are for reference only, not a basis for investment decisions.
