Interest Rates
Statutory Rate (No Contractual Rate)
| Application | Rate | Legal Basis | vs. Residential |
|---|---|---|---|
| Commercial lease | 6% per annum | Commercial Act Art. 54 | Residential is 5% |
Commercial leases are classified as commercial (business) transactions, so the Commercial Act rate of 6% applies rather than the Civil Act rate of 5%.
Contractual Rate
Lease agreements may specify a higher rate. Rates of 10%–20% per annum are common in commercial lease practice.
Legal Cap
| Standard | Cap |
|---|---|
| Interest Limitation Act | 20% per annum (excess is void) |
| Court discretion | Excessive rates may be judicially reduced |
Calculation
Late fee = Overdue rent × Annual rate × (Days overdue / 365)
Example (Statutory Rate)
| Item | Value |
|---|---|
| Monthly rent | ₩3,000,000 |
| Days overdue | 60 |
| Rate | 6% per annum |
| Late fee | ₩3,000,000 × 0.06 × (60/365) = approximately ₩29,589 |
Example (Contractual Rate)
| Item | Value |
|---|---|
| Monthly rent | ₩3,000,000 |
| Days overdue | 60 |
| Rate | 15% per annum (contractual) |
| Late fee | ₩3,000,000 × 0.15 × (60/365) = approximately ₩73,973 |
3-Month Arrears and Termination
| Rule | Details | vs. Residential |
|---|---|---|
| Threshold | Cumulative arrears ≥ 3 months' rent | Residential is 2 months |
| Calculation | Cumulative total, not consecutive | Same principle |
| Termination method | Landlord's notice (certified mail) | Same |
Post-Termination Considerations
- 3-month arrears is also a renewal refusal ground
- Deposit return obligation persists
- Arrears may be deducted from the deposit
- Key money protection may still apply even when landlord terminates lawfully
Management Fee Arrears
| Rule | Details |
|---|---|
| Separate from rent | Management fee arrears alone generally do not justify termination |
| Late interest | Contractual or statutory rate applies |
| Special clause risks | "Management fee arrears treated as rent arrears" clauses have disputed enforceability |

Best Practices for Landlords
- Specify a late fee rate in the lease — the statutory 6% may not provide adequate incentive for timely payment
- Stay within the 20% cap — courts can void or reduce excessive rates
- Track cumulative arrears precisely — the 3-month threshold is cumulative
- Separate rent and management fees in records — distinct billing for proper legal treatment
- Document all collection efforts — text, email, and certified mail
- Deduct arrears at lease termination — not during the lease term unless agreed
