National Pension Retroactive Contributions in 60 Installments: How Much Interest Will You Pay? 3 Things to Check Before Applying
In 2026, National Pension retroactive contributions can be paid in up to 60 installments, but choosing installment payments adds interest on top of the principal. Therefore, even if your total retroactive contribution is KRW 10,000,000, it does not mean you will pay only KRW 166,667 each month for 60 months. In particular, if you have already applied for retroactive contributions or are considering installments because paying a lump sum would be difficult, you should check not only your monthly payment amount but also how interest is calculated and any additional charges for missed payments.
