The key to comparing jeonse and monthly rent is deposit opportunity cost

Jeonse is not cost-free just because there is no monthly rent. A large deposit has financing cost or foregone return. This calculator compares the monthly opportunity cost of a jeonse deposit with the monthly-rent option: deposit opportunity cost plus rent.

Calculation basis

Jeonse monthly cost

Jeonse deposit × annual interest rate ÷ 12.

Monthly-rent cost

Rent deposit × annual interest rate ÷ 12 + monthly rent.

Difference

The gap shows which option has the lower monthly cost under the selected rate.

How to use

  1. Enter the jeonse deposit and the interest or opportunity-cost rate.
  2. Enter the monthly-rent deposit and monthly rent.
  3. Compare the monthly cost difference, then review financing terms, maintenance fees, and lease risk.

Frequently asked questions

What interest rate should I use?

If you borrow the deposit, use your loan rate. If you use cash, use the return you give up, such as deposit interest or expected low-risk return.

If monthly rent is cheaper, is it always better?

No. Lease stability, deposit safety, loan rules, maintenance fees, and moving costs can change the decision.

Does it include taxes or guarantee insurance?

No. It compares deposit opportunity cost and rent only. Real costs can include fees, insurance, and other charges.
