Lotto winnings calculator guide

This English page translates the Korean Lotto winnings calculator and calls calculateLottoTax and generateRankComparison. It preserves KRW 1,000 ticket-price deduction, the KRW 2,000,000 tax-free threshold, the 22% bracket, and the 33% bracket.

Taxable amount and ticket deduction

The source model deducts the purchase cost for one winning ticket only. The deduction is KRW 1,000 even if the user bought multiple tickets, because only the purchase cost tied to the winning ticket is treated as necessary expense.

Taxable amount is prize amount minus that deductible expense. If the taxable amount is KRW 2,000,000 or less, the result is tax-free and the net receipt equals the prize amount.

22% and 33% brackets

Above the tax-free threshold, the Korean source applies 22% up to KRW 300,000,000. That is 20% income tax plus 2% local income tax.

For the portion above KRW 300,000,000, the model applies 33%. That is 30% income tax plus 3% local income tax. A large jackpot can therefore have one portion taxed at 22% and another portion taxed at 33%.

Rank comparison

The rank comparison uses the Korean average-prize presets: first rank around KRW 2,000,000,000, second rank around KRW 60,000,000, third rank around KRW 1,500,000, fourth rank KRW 50,000, and fifth rank KRW 5,000.

Actual prize pools change by draw, rollover, winner count, and official payout rules. Use the calculator to understand tax mechanics before checking the official draw result and payment notice.
