Korea job change salary calculator guide

This English page translates the Korean job-change salary calculator and calls compareSalaries from the employment feature library. It compares gross pay, net pay, benefits, signing bonus, stock-option assumptions, and transition cost.

Net salary comparison

A job offer should not be compared only by headline annual salary. The Korean calculation breaks each salary into monthly gross salary, taxable monthly pay, National Pension, Health Insurance, long-term care, employment insurance, income tax, local income tax, total deductions, monthly net pay, and annual net pay.

The 2026 employee-side assumptions preserved from the Korean page include National Pension 4.5%, Health Insurance 3.545%, long-term care at 12.95% of the health premium, and employment insurance 0.9%. The National Pension base is capped, so very high salary increases do not raise pension contributions linearly forever.

Tax, dependents, and non-taxable pay

The calculator preserves progressive income tax from 6% to 45%, earned-income deduction, earned-income tax credit, dependent deduction, child tax credit, and local income tax. Dependents and children under 20 can change monthly withholding and annual net pay.

Monthly non-taxable pay matters. The Korean content highlights the KRW 200,000 meal allowance limit, and the English calculator keeps a non-taxable monthly field rather than treating every allowance as taxable salary.

Offer quality and transition cost

The Korean article frames pay increases by context: a normal move often needs a 15% to 30% raise, a same-level lateral move often needs 15% to 20%, promotion moves may justify 20% to 30%, and increases below 10% should be reviewed carefully against risk and workload.

The result includes total compensation with benefits and signing bonus, and it estimates current severance based on current tenure. Annual leave reset, probation period, commute, education support, medical support, and welfare benefits should be compared alongside monthly net pay.

Insurance and resignation cautions

Changing jobs can create timing issues for health insurance, National Pension records, tax settlement, severance, and unemployment benefit. Voluntary continuation for health insurance may be relevant for up to 36 months after leaving employment in some cases.

Signing bonuses are generally taxable as wage or employment-related income depending on structure. Stock options and RSUs can create separate tax timing, so the calculator should be used as a pay comparison before reading the detailed offer and tax terms.
