FAQ
- Where do the default commission and tax rates come from?
- They're sample figures commonly seen at Korean brokerages — a 0.015% commission and a 0.18% securities transaction tax — and you can freely change them to match whatever your own broker charges.
- How is the net return calculated?
- Sell commission and transaction tax are subtracted from your gross proceeds, your total cost basis (purchase amount plus buy commission) is subtracted from that, and the result is divided by your total cost basis and shown as a percentage.
