Calculate a Korean apartment tenant’s long-term repair reserve paid on the owner’s behalf, documented repayments, agreed offsets, and the remaining move-out settlement request.
Prefer the management office certificate total. Use the monthly estimate only when the certificate is not yet available.
Remaining amount to request
KRW 480,000
Calculation basis: Monthly estimate
Total paid by tenant

This result is still an input-based estimate. Article 31(9) of the Enforcement Decree requires management to issue confirmation without delay when requested.
A Korean apartment long-term repair reserve funds planned replacement and repair of major common facilities, such as lifts, exterior walls, roof waterproofing, and shared pipes.
The charge often appears on the monthly management bill paid by a tenant, but the current Joint Housing Management Act places the underlying collection obligation on the owner of the unit.
When a qualifying tenant actually pays on the owner’s behalf, the move-out settlement can therefore include a request for that paid amount.
This calculator does not invent a nationwide monthly rate.
Article 31(1) of the Enforcement Decree says the rate is set by each complex’s management rules with regard to the useful life of common facilities.
The management office payment certificate is therefore the preferred source, while monthly charge multiplied by paid months is only a provisional estimate.
This page applies a Korea-specific arithmetic screen based on rules checked on July 28, 2026.
It does not decide contract validity, limitation periods, late-payment interest, repair liability, litigation outcomes, or the validity of a unilateral offset.
Article 30(1) of the Joint Housing Management Act requires management to collect and accumulate the reserve from the owner of the relevant home according to the long-term repair plan.
A consolidated management bill paid by the tenant does not by itself change that underlying allocation.
Article 31(8) of the Enforcement Decree requires the owner to return the amount when a user paid it on the owner’s behalf.
Article 31(9) requires the management entity to issue payment confirmation without delay when the user requests it.
Article 2(1)6 defines a user to include a person leasing and using jointly owned housing, but expressly excludes a tenant of rental housing.
Public rental housing, private rental housing, and a complex before or after sale conversion may therefore require review of the lease and the separate housing regime instead of automatic reliance on Article 31(8).

A common mistake is to add every management-bill line containing the word repair.
The long-term repair reserve is accumulated under a long-term plan for major common facilities, while an ordinary repair and maintenance fee may cover current upkeep.
Similar names do not prove identical legal treatment, so use the exact line confirmed by management.
| Charge | Typical purpose | Enter here |
|---|---|---|
| Long-term repair reserve | Planned major common-facility work | Yes |
| Ordinary repair and maintenance fee | Current upkeep and minor repair | No |
| General management and utility charges | Staffing, administration, and use | No |
| Special repair reserve | A separate rental-housing regime may apply | Check separately |
The total paid by the tenant is the cumulative long-term repair reserve shown on the unit-level certificate.
This method captures rate changes and management adjustments that a single monthly figure can miss.
Remaining request = certificate total − amount already repaid − expressly agreed offset
If no certificate is available and the monthly line stayed stable, multiply the charge by the months actually billed and paid.
Add only separately verified reserve payments, recognizing that partial months and rate changes can still create a difference.
Total paid = monthly charge × paid months + other verified reserve payments
Remaining request = total paid − amount already repaid − expressly agreed offset
If repayments and agreed offsets exceed the amount paid, the calculator caps the applied settlement at the amount paid and shows zero remaining.
It also refuses to assume that a claimed repair cost or unpaid management charge is a valid offset.
Keep disputed deductions outside this arithmetic until the parties agree or obtain a separate determination.
The remaining request is KRW 570,000 after subtracting KRW 150,000 from KRW 720,000.
The average paid per month is KRW 20,000.
The provisional total is KRW 20,000 × 24 + KRW 50,000 = KRW 530,000.
Replace that estimate with the management certificate total before making the final request.
Ask the management office for a unit-level certificate covering the actual paid period. If the last management bill is not final, ask whether another reserve charge remains.
Send the owner a copy of the certificate and a compact calculation showing the total paid, prior repayment, agreed offset, and remaining amount.
Keep restoration costs and unpaid management charges separate unless their amount and use as an offset have been expressly agreed.
Retain the lease, management bills, receipts, certificate, settlement messages, and bank records together.
Identify the unit, the tenant’s occupancy and payment period, and the requesting user, then ask for a certificate of long-term repair reserve payments for that period.
Article 31(9) says the management entity must issue confirmation without delay when the user asks for it.
No automatic conclusion is built into this page. The wording, formation, and applicable mandatory rules may matter, so confirm the amount first and review the clause separately.
They can support an interim estimate, but rate changes, adjustments, and partial months can cause a mismatch. Prefer the management certificate for final settlement.
No. This calculator covers only the confirmed long-term repair reserve line and does not automatically combine a different management charge.
Enter an offset only after it has been expressly agreed. If disputed, keep the reserve principal and restoration issue separate and review the evidence for each.
Yes, using the amount confirmed to date. Recalculate after the final management bill and certificate are available.
Do not multiply one monthly figure across the whole period. Use the certificate total, or at minimum sum the separate rate periods while waiting for confirmation.
First verify that the building is within the long-term repair plan regime and that the billed item is the statutory reserve. A similar label alone is not enough.
No. The statutory user definition excludes a tenant of rental housing, so check the lease, housing operator, and separate governing regime.
The National Law Information Center OPEN API was checked on July 28, 2026.
The current Act record is Law ID 012345, MST 284009, and the current Enforcement Decree record is Law ID 012644, MST 287261; both records used here are effective July 1, 2026.
Use the monthly method to plan, then switch to the certificate total when management issues it.
Keeping prior repayment and an agreed offset in separate fields makes the final request easier to explain and audit.
This result is a planning calculation and does not replace legal advice on an individual Korean lease or dispute.
