1. Understanding Jeonse and Monthly Rent in One Clear Explanation

■ What is Jeonse?

Jeonse is a lease system where the tenant pays a large lump-sum deposit to the landlord and pays little to no monthly rent.
You get the deposit back at the end of the contract.

Key characteristics

• Requires a high deposit
• Very low or zero monthly expense
• Deposit is returned at the contract’s end
• Provides strong stability for long-term residents
• Burden may be high for foreigners due to the large deposit amount

---

■ What is Monthly Rent?

Monthly rent requires a much smaller deposit, but includes recurring monthly payments.

Key characteristics

• Low initial deposit
• Continuous monthly payments
• Good for short-term residents
• Long-term total cost may be higher than Jeonse

---

2. The Core Formula for Comparing Total Costs

The correct way to compare Jeonse and Monthly Rent is to evaluate the financial cost of the deposit and the total monthly payments.

■ Total cost of Jeonse

Jeonse’s cost is essentially the opportunity cost of the deposit.

Jeonse Total Cost = Deposit × Interest Rate

Example:
Deposit = 300,000,000 KRW
Interest rate = 3%
Annual cost = 9,000,000 KRW
Monthly equivalent = 750,000 KRW

---

■ Total cost of Monthly Rent

Total Cost = (Deposit × Interest Rate) + Monthly Rent

If the monthly rent is high, the long-term cost can exceed Jeonse even with a smaller deposit.

3. Realistic Scenarios for Foreign Residents (2025 Examples)

■ Scenario 1

Jeonse: 300M KRW
Monthly Rent: Deposit 2M + 900,000 KRW/month

Jeonse cost = 300M × 3% = 9M/yr → 750,000 KRW/month
Monthly Rent cost = 900,000 + 5,000 ≈ 905,000 KRW/month

Result: Jeonse is cheaper by roughly 150,000 KRW/month.

---

■ Scenario 2

Jeonse: 200M KRW
Monthly Rent: Deposit 1M + 700,000 KRW/month

Jeonse cost = 50,000/month
Monthly Rent = 700,300/month

Result: Jeonse is cheaper by roughly 200,000 KRW/month.

---

■ Scenario 3 (High Jeonse deposit case)

Jeonse: 500M KRW
Monthly Rent: 1M deposit + 1,100,000 KRW/month

Jeonse = 1,250,000/month
Monthly Rent ≈ 1,102,500/month

Result: Monthly rent is cheaper here.

Category	Jeonse	Monthly Rent
Initial Cost	Very High	Low
Monthly Cost	Very Low	High
Risk Type	Deposit risk	Payment risk
Best For	Long-term residents	Short-term residents

6. Understanding the Deposit Conversion Rate

This rate helps convert Jeonse into an equivalent monthly cost.

Monthly Equivalent = (Jeonse Deposit × Interest Rate) ÷ 12

Example:
200M Jeonse → 200M × 3% ÷ 12 = 500,000 KRW/month
