💡 A jeonse loan can cost less than monthly rent — but only if the numbers actually work out for your specific situation, which most simulators won’t show you honestly.
Why This Decision Is Harder Than It Looks
💡 The jeonse loan math isn’t just about interest rates — it’s about what you’d otherwise do with the money you don’t have to spend on rent.
When I first started looking into jeonse loans, I honestly thought the comparison to monthly rent was straightforward. Borrow the deposit, pay interest, compare to what you’d spend on rent monthly. Done.
It’s not that simple. Not even close.
The real calculation involves loan interest rates, deposit size, monthly rent for comparable units, inflation trajectory, and what you’d do with any freed-up cash. Miss one of those variables and your whole simulation falls apart. A recent graduate I know went through this exact process last year — comparing a jeonse loan against monthly rent for the same apartment in a mid-sized Korean city — and was genuinely surprised by what the numbers showed.
Let’s run it properly.
The Actual Numbers: Jeonse Loan Simulation
💡 Run this simulation with your own deposit size and local rent prices — the breakeven point shifts dramatically depending on where you live.
Here’s a realistic baseline scenario. Assume you’re looking at an apartment with a jeonse deposit of 280 million KRW (roughly $210,000 USD). You have about 80 million KRW saved. You’d need a jeonse loan to cover the remaining 200 million KRW.
The same apartment on a monthly rent (wolse) contract runs 900,000 KRW per month with a smaller deposit of 20 million KRW.
Here’s the math side by side over a two-year contract:
Jeonse Loan Path:
- Loan amount: 200,000,000 KRW
- Annual interest rate (mid-range government-backed loan): 3.8%
- Annual interest cost: 7,600,000 KRW
- Total interest over 2 years: 15,200,000 KRW
- Your own capital tied up in deposit: 80,000,000 KRW (opportunity cost applies)
Monthly Rent Path:
- Monthly rent: 900,000 KRW × 24 months = 21,600,000 KRW
- Smaller deposit: 20,000,000 KRW (mostly returned at end)
- No debt, no interest burden
On pure outflow, the jeonse loan wins — 15.2 million KRW over two years versus 21.6 million in rent. That’s a 6.4 million KRW difference, or about 266,000 KRW per month in savings.
But wait. That’s before you account for the 80 million KRW of your own capital sitting in the jeonse deposit. At even a conservative 3% annual return in a savings account or low-risk fund, that’s 4,800,000 KRW in forgone earnings over two years. Suddenly the gap narrows to roughly 1.6 million KRW total — or about 67,000 KRW a month.
Still in favor of the jeonse loan. But barely.

Where the Simulation Breaks Down
💡 Jeonse loan rates vary more than most people realize — and a 1% difference can flip the entire calculation.
Here’s where it gets interesting. The scenario above assumes a 3.8% loan rate — typical for government-backed housing loans (known as “bogeumjari” or similar programs) for income-qualified borrowers. But not everyone qualifies for those.
Private bank jeonse loans in Korea have ranged from roughly 4% to over 6% in recent years, depending on credit score, lender, and region. At 5.5% on a 200 million KRW loan, annual interest climbs to 11 million KRW — making the two-year total 22 million KRW. That’s actually more than monthly rent in our example.
Plot twist: the jeonse loan stops being the obvious winner the moment your rate creeps above roughly 4.8% in this scenario. Am I the only one who finds it strange that this breakeven point gets so little attention in most financial guides?
Loan terms also vary. Some jeonse loans require interest-only payments during the lease period with full principal due at the end (when you get your deposit back). Others allow partial principal repayment. Understand your repayment structure before signing — otherwise the end-of-contract balloon can catch you off guard.

The Right Choice for Limited Savings
💡 For someone with under 50 million KRW saved, the jeonse loan can be a legitimate path — just go in with clear eyes on the rate and the risk.
Here’s the honest framing for someone with limited savings trying to decide: a jeonse loan makes sense if you can access a subsidized or low-rate loan, the monthly interest payment is materially below area rents, and you’re stable enough that taking on that debt doesn’t create financial stress.
Monthly rent makes more sense if your loan rate would exceed 5%, you value zero debt above all else, or your income is irregular enough that a fixed monthly payment is actually easier to plan around than a large loan obligation.
Quick aside: the person I mentioned earlier — the recent grad comparing these options — ultimately chose a jeonse loan at 3.6% through a government housing program. Their monthly interest payment came to about 600,000 KRW, versus 880,000 KRW in rent for a comparable unit. Two years in, they’ve saved roughly 6.7 million KRW compared to what rent would have cost. Not life-changing, but real money — especially at the start of a career.
The simulation only works in your favor if you actually run it for your numbers. Don’t borrow this scenario wholesale — borrow the framework and plug in what’s real for you.
