What is the National Pension Continued Enrollment Calculator?

This calculator shows whether it pays to keep contributing to Korea’s National Pension after age 60. When you turn 60 you normally leave the mandatory scheme, but by applying you may continue as a “voluntarily continued insured person” until age 65.

This calculator is based on Korean National Pension rules (2026, National Pension Act effective 2026-06-17). If, at age 60, your total contribution period is under 10 years (120 months), you receive no monthly old-age pension — only a lump-sum refund. By continuing to contribute and reaching 120 months, that refund converts into a lifetime pension. The tool compares the refund against the lifetime pension and reports the monthly increase, payback period, and benefit ratio.

Who needs this

  • • People who reach age 60 with fewer than 10 years of contributions
  • • Anyone deciding between a lump-sum refund and a lifetime pension
  • • Those still earning after 60 who can keep paying
  • • People who want to raise their monthly pension by adding months
  • • Self-employed or freelance workers active past 60

How continued enrollment works (National Pension Act Art. 13)

Korea’s National Pension is compulsory for residents aged 18 to under 60. When you turn 60 you lose insured status, but Article 13 lets a current or former insured person apply to keep contributing until age 65.

Eligibility and terms

  • • Who: a current or former insured person who has reached age 60
  • • Period: from the approval date until age 65 (up to 5 years)
  • • Premium: paid entirely by the individual, like a regional (self-employed) subscriber (2026 rate 9.5%)
  • • Start: insured status begins on the day the application is accepted

When you cannot apply (Art. 13 proviso)

  • • A person who has never paid any pension contribution
  • • A person already receiving an old-age pension benefit
  • • A person who has already received a lump-sum refund after turning 60 with under 10 years

In short, once you start drawing the old-age pension or take the refund, continued enrollment is no longer available. Decide after turning 60 but before you begin receiving benefits.

The lump-sum refund (Art. 77)

A person with under 10 years of contributions who reaches 60 may claim a lump-sum refund of the contributions paid plus statutory interest (Article 77). For former workplace subscribers, the refund also includes the employer’s share.

Refund vs. lifetime pension

The refund is a one-time sum; the old-age pension is paid for life. In most cases, contributing a little more to reach 10 years produces a lifetime total that far exceeds the refund.

Net gain = lifetime pension total − extra contributions − forgone refund

When you choose the lifetime pension you give up the refund, so this calculator counts the forgone refund as an opportunity cost. Even so, the benefit ratio is often several times over, showing how powerful securing the pension right can be. Note that the refund claim is subject to a 5-year statute of limitations.

Three drivers of the profit-and-loss result

1. The 10-year (120-month) pension right

Below 10 years you receive no monthly pension at all — only the refund. Reaching 120 months converts that into a lifetime pension, so securing the right is decisively favorable.

2. Redistribution (the A value)

The benefit uses the average income of all subscribers (A value, about KRW 3.19 million in 2026) plus your own income (B). The lower your own income, the larger the A-value share, so even minimum contributions can return several times what you pay.

3. Longevity and payout years

The old-age pension is paid from the claiming age (65 for those born 1969 or later) for life. The longer you live, the larger the total. Women, with a longer life expectancy (about 87), tend to show a higher benefit ratio than men under the same inputs.

How to use the calculator

Step 1: Basic info

Enter birth year and sex. Birth year sets the pension claiming age; sex sets the life-expectancy assumption used for the payout period.

Step 2: Contribution history at 60

Enter total months contributed as of age 60 and your average standard monthly income. If it is under 120 months, the refund comparison appears automatically.

Step 3: Continued contribution terms

Enter how many months you will keep contributing (up to 60) and the standard monthly income. Selecting prior workplace-subscriber status refines the refund estimate.

Step 4: Read the result

See the monthly increase, payback period, benefit ratio, net gain, and verdict. If you have income, choose a marginal tax rate to reflect the income-deduction tax saving.

Calculation notes and formulas

  • • Monthly pension: annual = 1.29 × (A + B) × (1 + 0.05 × excess-years-over-20), divided by 12; the 10–20 year band is pro-rated by months/240. Under 120 months returns zero.
  • • Extra contributions: summed year by year at the reform premium schedule (9.5% in 2026, rising to 13% by 2033), fully self-borne.
  • • Refund: contributions (months × income × 9%) plus a simple-interest approximation for statutory interest.
  • • Claiming age: the later of the statutory claiming age and the age at which contributions end.

All figures are pre-tax, nominal estimates and do not adjust for inflation or annual A-value changes. Use them as a guide, and confirm exact premiums, expected pension, and refund with the National Pension Service (call 1355) before deciding.

Frequently asked questions

Q. How is this different from voluntary enrollment?

A. Voluntary enrollment lets non-earners aged 18 to under 60 join by choice. Continued enrollment lets someone who has just lost insured status at 60 keep paying until 65 under Article 13. The ages and the legal basis differ.

Q. Until when can I keep contributing?

A. Until age 65. You apply after turning 60, and insured status starts when the application is accepted. You cannot apply if you already receive the old-age pension.

Q. How much is the premium?

A. You pay it in full, like a regional subscriber. The 2026 rate is 9.5% applied to your standard monthly income (floor KRW 400,000, ceiling KRW 6.37 million). Unlike a workplace subscriber, no employer pays half.

Q. Is the refund ever the better choice?

A. Usually the lifetime pension wins, but if your life expectancy is very short or you urgently need a lump sum, the refund can be preferable. Check the benefit ratio and payback period for your situation.
