Overview

The National Pension Calculator estimates monthly pension contributions and projected benefits based on your income. Korea's National Pension requires a combined 9% contribution (4.5% employee + 4.5% employer), calculated on the standard monthly income (capped at KRW 5.9M).

Formula

Monthly Premium = Standard Monthly Income × 9% (4.5% employee + 4.5% employer)

• Upper cap: KRW 5.9M → Max premium KRW 531,000 (employee: KRW 265,500)
• Lower cap: KRW 370,000 → Min premium KRW 33,300

Estimated Benefit = Enrollment Period × Income Replacement Rate × (A + B) / 2
• A: Average income of all subscribers
• B: Your average income during enrollment
