How It's Calculated
The comparison calculates the effective annual housing cost for each option:
• Jeonse Cost = Jeonse Loan Interest + Opportunity Cost of Own Deposit - Loan Interest = Jeonse Loan Amount × Annual Interest Rate - Opportunity Cost = Own Deposit × Expected Investment Return Rate - Total Jeonse Annual Cost = Loan Interest + Opportunity Cost − Deposit Appreciation (if any)
• Wolse Cost = (Monthly Rent × 12) + Opportunity Cost of Wolse Deposit − Monthly Rent Tax Credit - Tax Credit: Up to 17% of annual rent for eligible renters (income ≤₩70M)
The calculator compares both totals and shows the annual cost difference. A break-even analysis shows at what interest rate or rent level the two options equalize.
⚠️ Disclaimer
This comparison uses simplified assumptions about investment returns and interest rates, which fluctuate over time. It does not account for Jeonse fraud risk, deposit return risk, or housing market changes. Your personal financial situation and risk tolerance should guide the final decision.

Frequently Asked Questions
What is Jeonse?
Jeonse is a unique Korean rental system where tenants pay a large lump-sum deposit (typically 50-80% of property value) instead of monthly rent. The deposit is fully returned when the lease ends.
What is the conversion rate?
The conversion rate calculates the implied return rate when converting between Jeonse and Wolse. The legal maximum rate in Korea is the base rate + 2% (about 5.5% in 2026).
Why include opportunity cost?
If you tie up a large sum in a Jeonse deposit, you lose the potential investment returns on that money. This calculator factors in what that money could earn elsewhere.
Which is better in 2026?
It depends on your financial situation. Generally, Jeonse is better when interest rates are low and you have savings. Wolse is better when rates are high or you prefer liquidity.
