Insurance Calc is a free set of insurance calculators that estimate Korean health insurance (silson) copay and reimbursement, pension insurance payout, and coverage analysis.
All calculations run in your browser, and we transparently publish the assumptions and variable constants used. Results are estimates for reference only.
What is Insurance Calc
Insurance Calc is a free set of tools that helps you quickly gauge your situation — whether you want to know your reimbursement before a health insurance claim, are preparing for retirement with pension insurance, or are unsure which coverage to secure first. We make the complex copay structure, pension accumulation and payout math, and coverage priorities understandable by sharing the formulas and assumptions used.
Editorial principles (E-E-A-T)
- Experience — we reflect the items actually used in real health claims and pension enrollment (covered/non-covered care, copay rates, accumulation/payout structures) and break results down item by item.
- Expertise — we calculate based on system rules and financial principles such as copay rates by generation, outpatient minimum deductibles, and monthly-compounding accumulation and annuity-withdrawal formulas.
- Authoritativeness — we cite the standards of official bodies such as the Financial Supervisory Service, the General Insurance Association of Korea, and the Korea Life Insurance Association, with source links.
- Trustworthiness — we publish formulas and assumptions and clearly note that results are estimates. Inputs are not collected or stored.
Data sources
The standards used in each calculator are based on the official materials below. Copay rates, deductibles, crediting rates, and similar values can change by product and over time; we update to the latest values when they change.
- Financial Supervisory Service — standard terms for health insurance, insurance comparison and integrated guidance
- General Insurance Association of Korea — health insurance copay rates and product disclosures
- Korea Life Insurance Association — pension and whole-life product disclosures
- National Tax Service Hometax — pension income tax and tax-credit standards
A note on accuracy
All Insurance Calc results are estimates for reference only, based on your inputs and published formulas and assumptions. Health insurance copay varies by product, riders, annual caps, and number of visits, and the pension insurance payout is a simple estimate that excludes fees, crediting-rate changes, and taxes. The coverage analysis is a check against general guidelines, not a personalized plan. For final decisions, confirm with your insurer's terms, official bodies such as the Financial Supervisory Service, or a professional.
