How much can I borrow mortgage calculator
Use our free mortgage calculator to work out how much you might be able to borrow from mortgage lenders in Ireland.
How much can I borrow?
Whether you’re a first time buyer starting out on your mortgage journey, a home mover looking for a larger property, or a landlord looking to invest, the first step in your mortgage application is finding out how much you can borrow.
Our mortgage borrowing calculator helps you calculate the most you might be able to borrow with a mortgage based on your income and deposit.
What affects how much you can borrow?
There are several things that affect how much you can borrow in Ireland. Here’s the main factors that lenders take into account when assessing your mortgage application.
How much do lenders let you borrow?
The easiest way to find out how much you can borrow is to use our mortgage calculator, but this will only give you the maximum amount you might be able to borrow based on lending measures in Ireland.
You could also go to a broker or lender directly to find out what you could borrow. They’ll assess your financial situation and give you a realistic idea of how much they could lend you.
Some lenders in Ireland, like Bank of Ireland, also have mortgage calculators based on their specific criteria. Simply enter a few details about each borrower, such as:
- Marital status
- Number of dependents
- Employment status
- Gross salary
- Monthly outgoings
Once the details are submitted, you’ll get an instant estimate of how much you could borrow from that lender. You can then use our repayment calculator to find out how much your monthly repayments could be based on how much you can borrow.
Who sets the borrowing limits in Ireland?
The Central Bank of Ireland is responsible for borrowing limits. Lenders follow Central Bank borrowing guidelines, known as mortgage measures, which sets the Loan to Value (LTV) and Loan to Income (LTI) limits.
These mortgage measures were set out in 2015 and updated in 2023 to help:
- Ensure lenders lend responsibly
- Ensure you borrow what’s affordable
- Keep the economy stable
These measures are reviewed each year, and may be changed if needed, to maintain a stable economy in Ireland.
What are the mortgage measures?
There are two types of limits Central Bank has put in place for residential properties.
1. Loan to Value (LTV) limit
This cap is based on your property value. The remaining percentage is the amount of deposit you must contribute. LTV limits vary depending on the type of buyer you are:
- First time buyers: The LTV is 90%, so you need a 10% deposit.
- Second and subsequent buyers: The LTV is 90% so you need a 10% deposit.
- Buy to let buyers: The LTV is 70% so you need a 30% deposit.
2. Loan to Income (LTI) limit
This cap is based on your income. If there are two of you on the mortgage, you can borrow a sum based on your combined salaries. The LTI depends on what type of borrower you are:
- First time buyers: You can borrow up to 4 times your income, so if your income is €40,000, you could borrow up to €160,000
- Second and subsequent buyers: You can borrow 3.5 times your income, so if you have a joint income of €100,000 you could potentially get a mortgage of €350,000
Can lenders override the limits?
Yes, the Central Bank allocates a percentage of mortgages, that can go over the LTI limit or under the LTV limit.
These exemptions are allocated based on the type of buyer:
- First time buyers: 15% of mortgages can go above the 4 times income cap
- Second and subsequent buyers: 15% of mortgages can go above the 3.5 times income cap
- Buy to let buyers: 10% of mortgages can have less than a 30% deposit.
To be considered for a mortgage that’s outside of the usual limits, you’ll need to be a low risk to the lender, and able to afford the larger payments. Lenders must review each borrower and their circumstances on a case-by-case basis.
How much can you afford?
The amount you’re able to borrow isn’t necessarily the amount you should borrow. A smaller mortgage would mean lower repayments and reduced costs overall.
Lenders will take into account your current outgoings but can’t predict how these may change so bear in mind how your circumstances could alter in future.
