Korean Housing Subscription Recognized Payments Calculator

Korean public housing savings: balance versus recognized deposits

Putting a lump sum into a Korean housing subscription savings account does not necessarily make the entire sum count on a housing announcement date.
Recognition depends on the allocated monthly installments, their contractual due dates, actual payment dates and installment caps.
Households reviewing an older account, or parents helping an adult child save, should inspect the installment ledger as well as the balance.

This calculator applies Korean 2026 rules to your entered ledger and target announcement date.
It estimates recognized installment count and amount, paid deposits still awaiting recognition, and the next effective recognition date.
Change a catch-up or advance-payment schedule and save the complete CSV for a bank review.
The calculation excludes interest and does not calculate a tax deduction or the actual account balance.
It does not determine eligibility, priority or the probability of obtaining housing.

Records to prepare before entering the ledger

The ledger must include every installment from opening because late and advance days accumulate.
Entering only recent installments and moving the opening date forward would erase earlier delays and produce a different estimate.
For an older account, generate enough monthly rows, then replace their dates and amounts with the bank’s records.
The editor displays twelve installments per page; calculation and CSV export include every entered row.

How late and advance payments affect recognition

This applies the Article 10(3) formula in the Rules on Housing Supply to a complete, ordinary account ledger.
Each installment uses only the ledger prefix through that installment.
Appending later future payments does not retroactively increase recognition for an earlier announcement.
Bank corrections, conversions and other special handling can produce different official cumulative totals, so those accounts are outside the automatic model.

The KRW 100,000 and 250,000 caps follow due dates

An overdue installment with an October 2024 due date remains subject to the KRW 100,000 cap even when paid in 2026.
Conversely, depositing only KRW 20,000 for an installment under the higher cap recognizes only KRW 20,000.
Changing a completed payment in the calculator changes the scenario; it does not increase the deposit recorded by the bank.
Cancellation and re-payment of older advance installments require bank review because the correction can also change cumulative advance days.

Above-cap deposits are excluded from the recognized savings total in this model.
They are not treated as money lost or as a fee; the actual deposit balance remains a matter for the bank’s records.
The current statute’s effective date, 2026-06-15, and the installment-cap boundary, 2024-11-01, are distinct dates.

Step-by-step instructions

1. Confirm the account scope. Use an ordinary account opened as an adult, without special recognition or corrections, and include the complete installment sequence.
   
2. Set opening, announcement and target. Use the announcement’s reference date rather than the application submission date.
   
3. Generate and edit the ledger. Generation replaces existing edits with an on-time schedule, so save anything you need first.
   Use the bank’s contractual dates and allocated amounts.
   
4. Enter actual late or advance-payment dates. For catch-up payments, apply a common date and review how the money is allocated.
   Installment 1 remains paid on the opening date.
   
5. Review and export. Inspect pending deposits and the next effective date, then compare the complete CSV with the bank’s recognition records.
   

Generated monthly dates remain anchored to the original opening day.
Opening on 2024-01-31 generates 2024-02-29 and then 2024-03-31; opening on January 31 in 2025 uses February 28.
Holiday and bank business-day adjustments are not automated.
If the bank’s due date differs, edit it within the corresponding month.

Worked examples: on time, late and in advance

Reading the result cards and pending amounts

• Recognized count and amount: installments satisfying both payment and recognition conditions by the inclusive cutoff, and their capped amounts.
  
• Paid but awaiting recognition: deposited money whose due date or delayed recognition date has not arrived.
  The displayed amount is already capped.
  
• Payment after cutoff: an actual or planned payment dated after the announcement.
  It is excluded from that cutoff’s recognized count and amount.
  
• Unpaid or unscheduled: an installment with a blank payment date.
  No next recognition date is invented before a payment date is supplied.
  

Deposits by cutoff equal recognized amount plus pending eligible amount plus above-cap deposits.
The count of advance payments still waiting for their due date is a classification within the pending deposits, not an additional count to add again.
The next recognition date can depend on a future scheduled payment.
Missing that payment changes the outcome, so review standing-order dates and available funds together.

Three practical uses before an announcement

Article 27 of the Rules on Housing Supply describes the competition ordering for National Housing general supply.
Its ordering uses recognized savings totals for homes exceeding 40 square meters and installment count for homes of 40 square meters or less, together with other conditions such as the period without home ownership.
Special supply and individual public-housing announcements may impose separate conditions.
The result is therefore not a project-specific selection forecast.
