For this wolse example, monthly rent, maintenance fee, and loan interest estimate are combined into monthly housing cash flow and compared with monthly income. Deposit and move-in cash are shown separately.

Jeonse can mean little or no rent — but the deposit, loan interest, return risk, and contract still matter.

This is an estimate-only cash-flow view. It does not judge whether a contract is good, affordable, safe, or suitable. Actual costs may vary by building, contract, maintenance fees, loans, bank terms, and official rules.

Next checks

  • The deposit risk is a separate question from the monthly cost.
  • Before you send money, re-check the address, contract, landlord, and account-holder name.
  • Before a big transfer, check your bank limit and how you'll verify it.

What to check next

Before you send rent or deposit money

The result is an estimate from your own numbers. It doesn't verify the property, the landlord, the contract, or your deposit — and it can't say whether the cost is affordable for you.

How to read the result

  • Use the monthly figure to weigh rent, maintenance, and loan interest together.
  • Keep the deposit separate from monthly cost — getting it back is its own question.
  • Change one input at a time when you compare wolse, jeonse, and semi-jeonse.

What to check before sending money

  • Confirm the address, unit, landlord, account-holder name, how you pay, and the refund terms.
  • Read the contract closely, and get qualified help on any clause you're unsure about.
  • Check the property and lease rules through official or professional sources before you sign.

Common mistakes

  • Thinking a low monthly rent means the contract is safe.
  • Paying off a chat message alone, or skipping the account-holder name.
  • Forgetting maintenance, move-in costs, loan interest, or the deposit risk.

One more reminder

Lease rules depend on the contract type, registration, property status, and the law. Check official sources or a qualified professional before you sign or send money.

Quick read

Plain-language explanation

See your real monthly housing cost, how big the deposit is next to your income, and the cash you'll need to move in — for wolse, jeonse, or semi-jeonse.

How this tool works

  • Enter the deposit, rent, maintenance fee, loan interest, move-in cost, your income, and the lease type.
  • It adds rent, maintenance, and loan interest into one monthly housing cost.
  • Then it shows the deposit as a multiple of your income, and the deposit plus move-in cost as the cash you'd need up front.

Example scenarios

  • Compare a wolse room: KRW 10,000,000 deposit, KRW 700,000 rent, and a separate maintenance fee.
  • For jeonse, set rent to 0 and add the loan interest if you're borrowing for the deposit.
  • Use semi-jeonse when there's both a sizeable deposit and monthly rent.

Important notes

  • It only compares the numbers you put in. It won't tell you whether a contract is good, affordable, or safe.
  • Jeonse can mean little or no rent — but the deposit size, loan interest, return risk, and contract still matter.
  • Check the actual contract, official sources, and a qualified professional before you sign.

FAQ

Does this tell me what I can afford?

No. It's an estimate-only view of the numbers — it doesn't judge what's right for you.

Does it include maintenance fees and loan interest?

Yes — you can enter both by hand. But it doesn't verify your loan terms or contract.
