Korea parental leave income calculator guide

This English page translates the Korean parental leave income simulator and calls runSimulation. It keeps maternity leave, paternity leave, parental leave tiers, 6+6 benefit tiers, reduced hours, parent pay, child allowance, and monthly cash-flow logic.

Parental leave pay tiers

The Korean page reflects the expanded parental leave period up to 18 months in 2025 and removes the old 25% post-payment approach from January 2025. General parental leave is modeled as 100% for months 1 to 3 with a KRW 2,500,000 cap and KRW 700,000 floor, 100% for months 4 to 6 with a KRW 2,000,000 cap, and 80% for month 7 onward with a KRW 1,600,000 cap.

For a single-parent path, the first 3 months use a KRW 3,000,000 cap. The simulator keeps monthly wage, household type, single-parent status, company type, timeline segments, selected subsidies, and multiple-birth status as actual inputs to the Korean calculation function.

Birth leave and 6+6 benefit

Maternity leave is 90 days for a single birth and 120 days for multiple births. For SMEs, employment insurance can cover the whole period up to the monthly cap, while large companies generally pay the first 60 days, or 75 days for multiple births, before employment insurance covers the rest under the modeled rules.

Paternity leave is modeled as 20 paid days with a cap of KRW 1,684,210. The 6+6 parental leave path applies when both parents use eligible leave for a child under 18 months, with month caps of KRW 2,500,000, KRW 2,500,000, KRW 3,000,000, KRW 3,500,000, KRW 4,000,000, and KRW 4,500,000.

Reduced hours and child subsidies

The reduced-hours path applies to children age 12 or under, or up to elementary school grade 6, with weekly hours reduced to the 15 to 35 hour range and a maximum period up to 24 months. The first 10 reduced hours are paid at 100% with a KRW 2,500,000 cap, and the remaining reduced hours use 80% with a KRW 1,600,000 cap.

The Korean simulator also includes government child subsidies. Parent pay is KRW 1,000,000 per month for age 0 and KRW 500,000 per month for age 1, while child allowance is KRW 100,000 per month for children under age 8. The simulation adds these to monthly household income.

Cash-flow interpretation

The result reports total months, monthly income rows, total income, each spouse income, subsidy income, average monthly income, normal monthly income, income reduction rate, total expense, total balance, and shortfall months. This makes it a household liquidity simulator, not just a benefit cap table.

Parental leave benefit is generally not taxable as wage, but other income, side work, employer policy, delayed payment, and employment-insurance eligibility can affect actual cash flow. The Korean content warns that additional income below KRW 1,500,000 per month may be relevant to benefit review.
