Korean Post-Retirement Health Insurance Calculator
Compare 3 scenarios of Korean post-retirement health insurance: employee, regional, and voluntary continuation β plus dependent eligibility.
About this tool
Korean Post-Retirement Health Insurance Calculator simulates monthly premiums under four post-retirement enrollment modes β re-employed (workplace), regional, voluntary continuation, and dependent β using NHIS official formulas (7.09% of monthly remuneration / regional score-based + 12.95% long-term care). It auto-decides which months are favorable for voluntary continuation (capped at 36 months) and checks dependent eligibility (annual income β€ β©20M, property tax base β€ β©540M, etc.). It also reflects the 50% public-pension inclusion and lets you simulate how property sales or rental decisions move premiums. All calculation runs in your browser; no input is uploaded.
Use cases
Scenario 1
Late-50s before retirement
Six months before retirement, compare 36 months of voluntary continuation against immediate regional enrollment to find the lower cumulative premium.
Scenario 2
Dependent enrollment under spouseβs plan
A retiree whose spouse is workplace-insured checks dependent eligibility against the β©20M income / β©540M property thresholds.
Scenario 3
When NPS payouts begin
When β©1M/month NPS payouts begin, β©500k (50%) is added to the insurance income base β model this into your withdrawal plan in advance.
Scenario 4
Retiree with rental properties
For a retiree with rental income, compare regional-insured premium scoring before and after a potential property sale.
Scenario 5
Switching to self-employed vs. voluntary continuation
When transitioning to a one-person business after retirement, compare 36 months of voluntary continuation against immediate regional enrollment.

Frequently asked
- Q. Who can apply for voluntary continuation?
- A. Only those who were workplace-insured for β₯1 year within the 18 months before retirement, and you must apply by the 25th of the month following retirement. Cap is 36 months.
- Q. Are the dependent thresholds strict?
- A. Yes. Default thresholds: total annual income β€ β©20M and property tax base β€ β©540M (or β€ β©900M with income β€ β©10M). Even β©1 of business income disqualifies you.
- Q. If I get β©1M/month NPS, how much does the premium rise?
- A. Half (β©500k) is added to the insurance income base, typically raising the regional premium by β©30kββ©50k/month β the tool reflects this automatically.
- Q. Will the result match the official NHIS calculation?
- A. It applies the published formulas as a close approximation; variance of Β±10% is typical. Final premiums are issued by NHIS each November.
- Q. Where is my financial input stored?
- A. Nowhere outside your browser. All calculation runs locally and inputs are wiped when you close the tab.
