Presale rights premium profit calculator

This English page follows the Korean presale and occupancy-rights premium calculator for purchase premium, paid amount, interim loan, balance loan, resale premium, post-move-in sale, tax, and ROI.

Tax bands and deduction

Presale rights are counted as houses from 2021 for relevant Korean tax-rule checks. Non-regulated area under 1 year uses 45 percent in the guide, while regulated under 1 year uses 70 percent and 1 to 2 years uses 60 percent.

Basic capital gains rates 6 to 45 percent can apply where the special presale-right short-term rates do not override them. Basic deduction KRW 2.5 million and local income tax 10 percent are included in the model.

Profit calculation

The Korean calculator subtracts acquisition premium, paid installment, options, contributions, interest, brokerage, capital gains tax, and local income tax from the expected resale or post-move-in proceeds.

Long-term deduction does not apply to resale of presale rights. That is why a high nominal premium can show a much lower after-tax ROI.

Risk reading

Use the result with the actual sale contract, installment schedule, loan conditions, regulated-area status, expected completion timing, resale restrictions, and tax house-count status. Premium trades are highly sensitive to tax and loan assumptions.
