South Korea retirement income: a worked example

Invented figures, not official pension rates. Ages are scenario inputs, not eligibility ages. An altered start age does not change the NPS amount. Update the amount from a matching official estimate.

What does this example show?

With spending of ₩3,000,000 a month, an entered pension of ₩1,600,000 from age 65, and no investment growth or inflation, the plan needs ₩600,000,000 at age 60 to last until age 90. Of that, ₩180,000,000 covers the period before the pension starts.

Prepare the South Korea inputs

Combine an NPS benefit estimate with workplace or private pension payments. Explore how savings in won could bridge the time between leaving work and pension income. National Pension access depends on the applicable age and insured history. NPS explains different old-age pension categories and how earnings may affect payments. Use your personal estimate and date; the example ages on this page are not an eligibility assessment.

Every assumption in the baseline

Current age / stop working: 60 / 60
Plan until age: 90 (exclusive)
Accessible savings at retirement: ₩600,000,000
Further saving: ₩0 per month
Spending after tax: ₩3,000,000 per month
Entered pension after tax: ₩1,600,000 per month, age 65 onward
Other income streams: ₩0
Net nominal return / inflation: 0% / 0% per year

All figures use today's purchasing power. The pension is an illustrative recurring payment. The model does not assess eligibility, taxes, access restrictions or a benefit increase for claiming later. The example uses zero return to make the arithmetic easy to reproduce; zero is not a return forecast.

Follow the two periods

Age 60 to 65: savings cover all spending.
5 years × 12 months × ₩3,000,000 = ₩180,000,000.
Age 65 to 90: the pension covers part of spending.
Monthly gap = ₩3,000,000 − ₩1,600,000 = ₩1,400,000. Over 25 years, savings supply ₩420,000,000.

Total capital needed: ₩180,000,000 + ₩420,000,000 = ₩600,000,000. At a nonzero return, the calculator discounts each monthly gap. It never borrows against future pension income.

Change one assumption

Same starting savings and spending, different timing · KRW
Scenario	Capital needed	Additional capital needed	Try it
Baseline bridge	₩600,000,000	₩0	Load scenario
Pension starts one year later	₩619,200,000	₩19,200,000	Load scenario
Plan for five more years	₩684,000,000	₩84,000,000	Load scenario

Delaying the same pension by one year increases the required savings by ₩19,200,000. Planning five years longer adds ₩84,000,000. Actual later-claiming benefits may differ: get a new official estimate before using a real alternative date.

What this leaves out

An employer retirement benefit or private account is a separate resource from National Pension. Establish whether it will fund recurring payments or remain available capital. Count the resource once, and check its access and tax conditions with the provider.

The result is a deterministic illustration with no market volatility, changing taxes, care-cost shock or inheritance target. Payments remain constant in real terms, which may overstate a pension that does not keep pace with prices. Three income streams are available; combine payments only when their dates and money basis match.

The first twelve-month budget in the calculator solves for a fundable spending level. It is a separate result from your entered target. In a stressed scenario it can be lower than the target; the capital-gap table above keeps the original spending target unchanged.
