About Insurance Age (Sang-ryeong-il)
In South Korea, insurance companies use a unique aging system called "Sang-ryeong-il" to determine your insurance age. Unlike your actual birthday, your insurance age increases exactly 6 months after your birthday.
Understanding this date is crucial because insurance premiums typically increase by 5-10% every year your insurance age goes up. This calculator helps you pinpoint exactly when that change will happen, giving you a "Golden Time" window to sign up for insurance at lower rates.
