Enter your enrollment years and average income to estimate your pension benefit.
This is a simplified reference estimate using the National Pension Act's basic pension formula for the old-age pension — payout rate 1.2 × (A-value + B-value) × [1 + 0.05 × (years of enrollment − 20)]. In practice, the B-value is the average of your income for each year of enrollment, each revalued to present-day terms, but this calculator uses the average income you enter as-is. It does not include the dependent family pension addition (spouse/children/parents), reductions or increases for early or deferred old-age pension, or annual cost-of-living adjustments to the pension amount. The A-value (average standard monthly income of all subscribers) changes every year; the default above reflects the value announced for 2025. For an accurate estimate, check the National Pension Service website ('내 연금 알아보기') or call the National Pension Service at 1355 (within Korea). This does not replace professional tax or pension advice.
