Frequently Asked Questions
What is the National Pension A-value?
The A-value represents the average monthly income of all National Pension subscribers. For 2026, it is ₩3,193,511. This value is updated annually and used in the pension benefit calculation formula.
What is the minimum contribution period to receive pension?
You need at least 10 years (120 months) of contributions to qualify for the old-age pension. With fewer than 10 years, you receive a lump-sum refund instead of monthly payments.
How does early claiming reduce my pension?
Early claiming reduces your pension by 6% per year (0.5% per month) before the normal claiming age of 65. Claiming at age 60 results in a 30% reduction. However, you start receiving benefits earlier.
How does deferred claiming increase my pension?
Deferred claiming increases your pension by 7.2% per year (0.6% per month) after age 65, up to age 70 for a maximum increase of 36%. This can significantly boost your monthly benefits.
Is National Pension taxable?
Yes, National Pension benefits are subject to income tax. However, the tax burden is relatively low as pension income receives various deductions. The tax is withheld at source when benefits are paid.

How It's Calculated
The NPS old-age pension benefit formula:
Monthly Pension = Base Amount × (1 + 0.05 × (n − 20)) for n ≥ 20 years, where n = contribution years.
Base Amount = 1.485 × (A + B) × (n/40). A = average monthly income of all NPS members (adjusted annually), B = your career average monthly income (revalued).
Key adjustments: • Early pension (before age 65): reduced by 6% per year (up to 5 years early = 30% reduction) • Deferred pension (after age 65): increased by 7.2% per year (up to 5 years = 36% increase) • Pension amounts are adjusted annually for inflation (CPI-linked).
