National Pension Early vs. Deferred Claims: Which Pays Off -- A 6% Cut or a 7.2% Bonus a Year

What Is Early Old-Age Pension -- Eligibility and Age

The Early-Claim Reduction Rate -- 6% a Year, Up to 30%

Claiming early comes at a cost. Every year you claim early cuts your benefit by 6%, so claiming the full five years early locks in a reduction of up to 30% for life. For example, someone who would receive 1,000,000 won a month at the standard age would see that drop to roughly 700,000 won a month if they claim five years early -- and it stays there. Reaching the standard age later does not restore the original amount. The reduction is permanent.

The Income Cap That Can Block Early Claims -- 3,193,511 Won a Month

Not everyone can apply for early old-age pension. It's only available to people who are "not engaged in income-generating work" above a set threshold. That threshold is the A-value (the average monthly income across all National Pension subscribers), which is 3,193,511 won a month for 2026. If your wage or business income exceeds that figure, you can't file a new early claim -- and if your income later rises above the threshold while you're already receiving early pension, payments can be suspended. Anyone who returns to work or starts a business after retiring should check this threshold before applying.

Deferred Pension -- How Much More You Get by Waiting

On the other side is deferred pension (yeongi yeongeum), for people who reach the standard pension age but choose to put off filing. You can delay your claim by up to five years past the standard age, and your benefit grows by 7.2% (0.6% a month) for every year you defer. Deferring the full five years raises your lifetime benefit by up to 36% above what you'd have received at the standard age. A detail that comes up often in these comparisons: the deferral bonus rate (7.2% a year) is actually higher than the early-claim penalty rate (6% a year). The tradeoff is that you receive nothing at all during the deferral period, so you need another source of income to cover that gap.

You Don't Have to Defer the Whole Amount

Deferred pension doesn't require an all-or-nothing choice. When you apply, you can choose to defer 50%, 60%, 70%, 80%, 90%, or the full amount, and receive the rest starting at the standard age as usual. Someone who needs some monthly income but has other assets to draw on might defer only half, capturing part of the bonus rate while still getting a partial payout right away. If your circumstances change after filing a partial deferral, you can also apply to start receiving the deferred portion before the five years are up.

Early or Deferred -- What Should the Decision Come Down To

Mathematically, the decision hinges on "how long you expect to live." Various calculations put the break-even age between claiming the maximum five years early and claiming at the standard age at roughly 76 to 77. In other words, if you pass away before that age, claiming early comes out ahead in total lifetime payments; live longer than that, and standard or deferred claiming wins out. That age is only a rough guide, though -- it shifts based on your own expected benefit amount and health. If you're not desperate for income right away, you can lean on the fact that deposit protection now covers up to 100 million won to bridge the gap with other savings while you defer. If you have a lump sum tied up in a term deposit, it's worth running the numbers on how much interest you'd lose by cashing out early before deciding which route actually pays off. If you'd rather split your retirement savings into safer assets like government bonds, it helps to start with the basics of bond investing. And if medical costs after retirement are a concern, it's worth checking in advance whether your long-term care copayment could be cut by 40-60% based on income, since that changes how much of a retirement cushion you actually need.

Summary

1) Early old-age pension requires at least 10 years of contributions and a minimum age by birth year (56-60), and cuts your benefit by 6% for every year claimed early, up to 30%. 2) You can't file an early claim if your monthly income exceeds the A-value (3,193,511 won for 2026), and payments can be suspended if your income later crosses that line. 3) Deferred pension can be delayed up to five years past the standard age, adds 7.2% a year up to 36%, and can be applied to just part of your benefit (50-90%) rather than all of it. 4) Once set, both the reduction and the bonus stay fixed for life. 5) Various calculations put the break-even age around 76 to 77, but that's only a rough reference point that depends on your individual situation.
