What Is the Korea Lease Deposit Dispute Calculator?

This calculator estimates Korean residential or commercial lease deposit refund disputes. It compares deposit, unpaid rent, maintenance fees, utilities, claimed restoration deductions, fair restoration value, overcharge amount, late interest, and total claimable refund.

The Korean page separates ordinary wear and tear from tenant-caused damage. It also accounts for useful life and residual value when estimating whether a landlord deduction is fair.

Important Note

Lease contract wording, photos at move-in and move-out, repair invoices, occupancy period, and notice records are decisive. The calculator does not replace document review.

Late Interest

  • The calculator can estimate late interest from the return due date.
  • Civil-law style delay interest is modeled at 5 percent where ordinary civil delay applies.
  • Litigation-promotion style interest can be modeled at 12 percent after lawsuit-related timing when selected.
  • Late interest is added to the expected refund to show total claimable amount.

Residential and Commercial Differences

Residential lease disputes often turn on move-out condition, restoration scope, deposit return timing, and whether the tenant preserved evidence before handing over possession. Commercial disputes can add interior construction, business-use wear, original-state clauses, and larger restoration invoices.

The calculator is useful for negotiation because it separates what the landlord claimed from what the model treats as fair. The difference becomes the overcharge or disputed deduction amount.

FAQ

Can a landlord deduct full replacement cost for old wallpaper or flooring?

Not automatically. The model applies useful-life and fair-deduction logic, so old facilities usually should not be charged at full new replacement value.

When should I calculate litigation interest?

Use it when a lawsuit or litigation-stage demand is realistically being pursued; for early negotiation, ordinary civil delay interest may be more conservative.

Legal Use Notice

This English page translates and adapts the Korean calculator content for Korea-based estimates. The interactive calculator reuses the same Korean pure calculation function as the Korean page, so the numerical result is aligned with the Korean service. It is an estimation tool, not legal advice for a specific dispute.
