Jeonse-Monthly Rent Converter (전월세 전환 계산기)
Convert between jeonse deposit and monthly rent using the conversion rate.
Overview
Jeonse is a Korean lease in which the tenant lodges a large refundable deposit and pays no monthly rent, the landlord taking the return on the deposit as compensation. Converting between a jeonse deposit and a monthly rent applies a conversion rate (전월세 전환율) to the portion of the deposit being exchanged, and the annual figure is divided by twelve to give the monthly amount.
Legal cap: BOK base rate (3.0%) + 3.5% = 6.5%

About
The rate is capped by law at the Bank of Korea base rate plus 3.5 percentage points. With a base rate of 3.0 percent, the ceiling stands at 6.5 percent, which limits how much monthly rent a landlord may demand in exchange for reducing a deposit. The cap binds on conversions during an existing tenancy rather than on the terms of a new contract.
Semi-jeonse (반전세), combining a reduced deposit with a monthly payment, has grown as interest rates made pure jeonse less attractive to landlords, and the conversion rate is what sets the exchange between the two components.
