Korea parental-leave return cash-flow calculator guide

This English page translates the Korean dual-income parental-leave return cash-flow simulator and calls runSimulation from the return-cashflow feature library. It compares continued leave, full-time return, and reduced-hours return using household income, childcare cost, extra work costs, fixed expenses, variable expenses, long-term impact, and tax benefits.

Household and childcare inputs

The Korean model stores household type, child age in months, childcare type, childcare hours, extra childcare cost, each spouse status, return type, monthly wage, reduced weekly hours, non-taxable amount, extra commute and lunch costs, fixed expenses, and variable expenses.

The English page builds the same FormState from DEFAULT_FORM and user controls, then passes it into runSimulation. This keeps child subsidy, childcare subsidy, and household expense handling aligned with the Korean page.

Scenario comparison

The simulation returns scenarios for continued leave, full-time return, and reduced-hours return. Each scenario includes spouse incomes, government subsidies, childcare costs, total childcare cost, extra cost, total income, total expense, net cash flow, and annual 12-month cash flow.

The result identifies bestScenario, verdict, verdict message, income gain, cost gain, net gain, break-even months, long-term impact, tax benefits, and monthly comparison rows. English users therefore get the same household cash-flow comparison rather than a single childcare-cost estimate.

Korean benefit constants

The Korean source keeps parental-leave allowance tiers, reduced-hours allowance, childcare subsidy by age, childcare cost tables, parent pay, child allowance, and tax-benefit assumptions in dedicated constants. Those constants drive the English result through the shared function.

Parent pay is modeled by child age, child allowance uses the under-age limit in the source, and tax benefits include child tax credit, education credit, and earned-income credit branches.

Long-term impact

The long-term output includes pension monthly gain, retirement-pay gain, career-risk score, and career-risk label. A return-to-work decision can improve current cash flow while increasing childcare and work-related costs, so the simulator separates income, cost, and long-term effects.

Actual daycare availability, employer reduced-hours approval, benefit application timing, spouse income, and tax filing can change the result. The calculator is a planning model that now stays in parity across Korean and English pages.
