Question 1

How do I use the stock return calculator?

Accepted Answer

Enter your buy price, quantity, and sell price. Select Korean or US stock to apply the correct tax rate and brokerage commission automatically. The calculator instantly shows your net profit and real after-tax return.

Question 2

How is the real return calculated including fees and taxes?

Accepted Answer

The real return is not simply (sell price - buy price) / buy price. For Korean stocks, a 0.18% securities transaction tax and brokerage commission (typically 0.015–0.25%) are deducted at sale. For US stocks, a 22% capital gains tax on profits over 2.5 million KRW and currency conversion fees must also be considered. This calculator deducts all of these automatically.

Question 3

How is the break-even point (BEP) calculated?

Accepted Answer

The break-even price is the minimum sell price needed to recover the commissions paid at purchase. For example, if you bought at 10,000 KRW with a 0.015% commission, your BEP is approximately 10,003 KRW. Enter your purchase details in this calculator to get your break-even sell price instantly.
