Problem

A 57-year-old soon-to-retire worker cannot predict their cash flow for the first 12 months after retirement. After receiving a lump-sum severance, they face health Insurance premium conversion from employer-based to regional ($112→$337/month / 15만→45만 원), voluntary National Pension continuation ($150/month / 20만 원), unemployment benefits ($1,200/month × 6 months / 160만 원), and children's tuition — all overlapping in ways that can lead to 'running out of cash at month 6' without warning. Even professional Retirement planning consultations ($750+ / 100만 원+) rarely produce a month-by-month cash flow table.

Solution

Enter your retirement date, severance amount, expected unemployment benefits, and fixed expenses (health Insurance, National Pension, tuition, living costs), and the service automatically generates a 12-month post-retirement cash inflow/outflow timeline. Deficit months are highlighted in red, and three scenarios to resolve the deficit (extended unemployment benefits, part-time income, installment severance payout) are compared.

Target: Ages 54–60, 6 months to 2 years before retirement, with spouse + 1–2 college-aged children, severance of $75,000+ (1억 원+)
Revenue Model: Free basic 12-month cash flow table. Per Transaction PDF Report at $5.90 (7,900원) for scenario comparison + optimal severance payout method analysis. Matching fees from Retirement planning expert referrals.
