Step 3 Voluntary continuation vs. discontinuation: total benefit + health insurance cost-benefit comparison

Problem

Retirees aged 55–60 must decide whether to voluntarily continue National Pension contributions (approximately $375/month). The National Pension Service tells them how much their monthly benefit increases with 5 more years of payments, but no tool provides an integrated view showing: (1) how many years it takes for the increased benefits to break even against the total additional contributions, or (2) how health insurance premiums change (since continued contributions count as income). Depending on the payment period and amount chosen, the difference can reach tens of thousands of dollars — yet most people decide by gut feeling.

Solution

Users enter their current enrollment period, contribution history, and expected benefit start age. The tool then generates a comparison table across 0/3/5/10-year voluntary continuation scenarios, showing: monthly benefit increase, total contributions paid, break-even age, and health insurance premium changes. Key differentiator: integrated break-even analysis combining pension benefits + health insurance premiums + total contributions.

Target: Ages 55–62, recently retired or approaching retirement, 20+ years of National Pension contributions, considering voluntary continuation
