Problem

Approximately 2.2 million freelancers and platform workers in Korea pay health insurance premiums as local subscribers, which are calculated based on income, assets, and vehicle ownership, resulting in premiums 2-3 times higher on average than those of workplace subscribers. There are ways to reduce costs such as voluntary enrollment, conversion to dependent status, and adjusting income reporting, but individuals find it difficult to find the optimal combination, leading to overpayment of 500,000-2,000,000 KRW annually (approx. $375-$1,500).

Solution

By entering income, assets, and family composition, it simulates the optimal combination of health insurance, national pension, and employment insurance enrollment, and visualizes monthly savings. Differentiation: reflects real-time health insurance premium calculation logic, pre-diagnosis of dependent eligibility, and one-click connection to partner tax accountants for consultation.

Target: Freelance developers, designers, and writers with annual income of 20 million to 100 million KRW (approx. $15,000-$75,000), solo entrepreneurs in their 30s-40s.
Revenue Model: Basic simulation free, detailed savings report 29,000 KRW per case (approx. $21.75), tax accountant connection fee 10,000 KRW per case (approx. $7.50).
