What Is the Korea Jeonse Deposit Late Interest Calculator?

This calculator estimates late interest when a Korean jeonse deposit has not been returned after lease termination. It calculates the unreturned deposit, total late interest, total claim amount, daily interest, monthly estimate, and period segments.

The model supports a simple 5% civil-law mode and a lawsuit mode that applies 5% before complaint service and 12% after service, preserving the Korean page's legal-rate logic.

Important Note

Jeonse deposit recovery can involve simultaneous performance issues such as delivery of the home and return of keys. Confirm the actual delay start date before relying on an estimate.

Core Formula

  • Unreturned deposit = total jeonse deposit minus already returned amount.
  • Civil-law interest mode applies 5% annually across the selected delay period.
  • Lawsuit mode applies 5% until complaint service and 12% after complaint service.
  • The model shows daily and monthly interest estimates so tenants can understand the cost of delay.

Practical Recovery Steps

  • Send clear written notice demanding return of the deposit.
  • Consider lease-right registration if moving out before receiving the deposit.
  • Use a payment order or deposit-return lawsuit when voluntary return fails.
  • Track partial payments because already returned amounts reduce the interest base.

Evidence to Keep

  • Lease contract, renewal notices, termination notice, and move-out communications.
  • Bank transfer records for deposit payment and any partial return.
  • Messages with the landlord about return timing.
  • Court complaint service date if lawsuit-mode interest is claimed.

FAQ

Why does the lawsuit mode use two rates?

The Korean model reflects ordinary civil interest before service and the higher litigation delay rate after complaint service.

Does partial return stop all interest?

No. Interest continues on the unreturned balance after subtracting amounts already returned.
