Loans calculators4
How much you can borrow and what you will repay.
This is where you check how much money is available before buying a home. The limit is not set by the price and your income alone. Whether the area is regulated, how much you already borrow, and how you repay all cut into it.

Where to start
Regulated Zone Checker
At the same price, a regulated zone changes the LTV from the start. Skip this and every number after it is off.
DSR Calculator
Loans you already hold eat into the limit for a new one first. You need to know what room is left before the limit calculation means anything.
Mortgage Limit Calculator
Only once you know the first two does the amount you will actually get come out.
Loan Repayment Simulator
What you can borrow and what you can repay are different. Total interest changes a lot with the repayment method.
Leave out the stress rate and the limit looks bigger than it is
Banks set the limit by computing repayments at a rate with an add-on, not at today's rate. A limit computed without it is larger than the real one. The Mortgage Limit Calculator and the DSR Calculator both include the add-on.
Not in this group
- Jeonse loan limits
- Renting has the deposit guarantee premium and deposit priority; the jeonse loan interest deduction is under Year-End Settlement.
- Personal (credit) loan limits
- There is no calculator for it yet. Put a credit loan into the DSR Calculator to see how much it shrinks your mortgage room.
The law this group rests on
