Korea first-year post-retirement cost calculator guide

This English page translates the Korean first-year retirement-cost calculator and calls calculatePostRetirementCost. It preserves severance tax, unemployment benefit, health-insurance option comparison, National Pension option, monthly living expenses, taxes, asset runway, and monthly cash flow.

Income after retirement

The Korean function calculates one-year income from net severance pay, unemployment benefit where eligible, other income, and interest income. Severance is reduced by retirement-income tax and local income tax using the source tenure-deduction and converted-salary logic.

Unemployment benefit depends on retirement reason, age, tenure, and average wage. Voluntary retirement, recommended resignation, and involuntary separation can produce different eligibility outcomes in the Korean model.

Health insurance and pension choices

Health Insurance can be voluntary continuation, regional subscriber, or dependent. The Korean function compares voluntary continuation premium, regional premium, dependent eligibility, recommended option, and monthly saving.

National Pension can continue, be exempted, or be excluded. The result includes annual National Pension burden, health-insurance burden, and monthly expense average so that insurance decisions are visible in the first-year cash flow.

Living costs and taxes

The expense model includes housing, management fee, food, transport, communication, education, private insurance, utilities, other expenses, property tax, and car tax. Annual tax and monthly projections are calculated from these entered costs.

Because the Korean page models detailed expense categories, the English page does not collapse retirement cost into one monthly expense field. The output keeps total expense, expense breakdown, and monthly cash-flow rows.

Runway and planning

The final analysis reports net balance, total assets, survival months, and saving tips. A negative balance shows how much of the asset buffer may be consumed during the first year after retirement.

Actual results depend on severance records, unemployment-center review, health-insurance notices, dependents, spouse employment, housing cost, loans, and investment liquidity. The English page uses the same Korean function for reliable parity, then users should confirm official figures.
