Korean NPS Pension Estimator
Compare early / normal / delayed Korean NPS scenarios without NPS login, with lifetime totals.
About this tool
Korean NPS Pension Estimator simulates monthly pension and cumulative payout to age 85 across three claim ages โ early 60, normal 65, delayed 70 โ from current age, contribution months, and standard monthly base. It approximates the public NPS formula (A-value, B-value, 40% target replacement rate, CPI-linked) and auto-applies the โ6%/yr early reduction and +7.2%/yr delay credit, including a break-even age curve. No NPS login required; export a PNG result card. All computation is client-side. Expect ยฑ5โ10% vs the official "My Pension" figures โ use as a pre-check, not a final number.
Use cases
Scenario 1
Early 60 vs normal 65 vs delayed 70
A 30-yr contributor compares monthly pension and the cumulative-to-85 curve across the three claim ages.
Scenario 2
Break-even age โ defer decision
Confirm the normal-vs-delay break-even sits near age 81โ83 for your numbers.
Scenario 3
Both spouses contributing
Stack each spouse's simulation to estimate retirement household pension and plan IRP / pension-savings top-ups.
Scenario 4
Insufficient months โ top-up effect
Below 120 months? See how additional payments or voluntary continuation lift the pension.
Scenario 5
Retirement gap analysis
Set a โฉ2M monthly retirement target, see what NPS covers, and quantify the private-pension gap.

Frequently asked
- Q. Does it match the official "My Pension"?
- A. It's an approximation; expect ยฑ5โ10% vs the official figures. Get exact values from nps.or.kr My Pension.
- Q. Is early claim a loss?
- A. Early claim cuts 6%/yr permanently โ 5 yr early = โ30%. Break-even ~ age 75โ77; living past that favors normal claim.
- Q. Delay credit?
- A. +7.2%/yr, up to +36% over 5 yr. Break-even ~ age 81โ83; living past that favors delay.
- Q. What if I have <120 months?
- A. Old-age pension needs 120+ months. Below that, a lump-sum refund applies; or extend via top-up payments / voluntary continuation.
- Q. Is this an NPS official tool?
- A. No. NPS / KNPS are independent; this is an unaffiliated simulator. Always cross-check with the official NPS estimator.
