How a Jeonse Loan Rate Hike Affects Your Monthly Burden
Jeonse loans are typically interest-only (balloon) loans, so the principal stays untouched while you pay interest each month. When the rate rises, that increase applies directly to your monthly interest — and the larger your balance, the bigger the felt impact for the same rate hike.
Monthly Increase Formula
Monthly Increase = Loan Balance × (New Rate − Old Rate) ÷ 100 ÷ 12
For example, on a $150,000 balance with a rate rising from 3.5% to 4.5% (a 1 percentage point hike), monthly interest climbs from about $438 to $563 — an increase of roughly $125 per month, or about $1,500 a year.
Responding to a Rate Hike
Variable-rate jeonse loans reset periodically based on a reference rate like COFIX. If the hike is significant, consider refinancing into a fixed-rate loan or a subsidized rental-deposit loan program to reduce your interest burden.
