How to use Korea Jeonse to Monthly Rent Calculator
Converts a Korean jeonse deposit into monthly rent and back, and checks whether a conversion rate exceeds the legal cap.
The Housing Lease Protection Act caps the rate at the Bank of Korea base rate plus 2 percentage points, so 5.0% a year while the base rate is 3.00%.
- Choose jeonse to monthly rent, monthly rent to jeonse, or rate check.
- Enter the jeonse deposit, the monthly rent deposit and the rent as needed.
- Enter a conversion rate or keep the default legal cap of 5.0%.
- Review the converted amount and the maximum rent under the cap.
Useful for
- Checking fair rent when a landlord proposes converting part of the deposit
- Comparing jeonse and semi-jeonse listings on the same basis
Limits and checks
- The cap applies when part of the deposit is converted to rent during a lease, not to brand-new contracts.
- The cap moves with the base rate, so check the Bank of Korea rate at the time of the change.
Worked example
Converting a KRW 300 million jeonse
Mode: jeonse to monthly rent Jeonse deposit: 300,000,000 Rent deposit: 50,000,000 Conversion rate: 5%
The default rate is the legal cap: the 3.00% base rate plus 2 points.
Rent conversion result
Monthly rent: 1,041,666 Jeonse minus deposit: 250,000,000 Annual rent: about 12,499,992
Amounts are truncated to whole won; the actual rent is negotiated with the landlord.
Common issues
The monthly rent deposit shows an error
The rent deposit must be smaller than the jeonse deposit; the difference is the amount that turns into rent.
The rate is flagged as above the cap
If rent × 12 divided by (jeonse − deposit) exceeds 5.0%, the excess cannot be charged mid-lease. Check whether it is a new contract.
How to interpret the result
If the requested rent exceeds the maximum under the cap, first confirm whether the change happens mid-lease.
