How much can you borrow calculator

If you’re planning to buy your first home or move house, our mortgage calculator helps you find out how much you could borrow from Ireland’s leading lenders.

Our calculator provides a starting point for planning your home purchase. Whether you’re a first time buyer, or looking to switch to a better deal, it’s the fastest way to find out what’s affordable based on your circumstances.

You can then compare mortgage rates and monthly repayments using Switcher.ie’s mortgage comparison tools.

Total income
This is your total annual income, if you're applying for a joint mortgage with someone else, include your combined annual income.
This is how much money you have to put towards buying your new home. If you're an existing homeowner, include the total amount of equity you have in your current property.

What are the maximum mortgage lending limits in Ireland?

Buyer type Max loan to income (LTI) Min deposit required
First-time buyer 4 x combined gross income 10%
Second/subsequent buyer 3.5 x combined gross income 10%
Buy-to-let investor Not restricted by LTI 30%

Real life examples

  • A lone first time buyer earning €50,000 could potentially borrow around €200,000 and, with a minimum 10% deposit, buy a property around €220,000.
  • A second time buyer couple with joint earnings of €90,000 might qualify for a mortgage of €315,000 and, with a 10% deposit, buy a property valued around €350,000

Bear in mind that meeting income limits does not guarantee a mortgage. Lenders use a stress test to ensure you can still afford your monthly payments if interest rates rise.

Mortgage repayment calculator

Whether you’re a first-time buyer, home mover, or looking to switch your mortgage, our mortgage repayment calculator gives you a quick and realistic estimate of what your repayments might look like with a range of Irish lenders.

It’ll search our mortgage database for the best interest rates, and present you with the cheapest mortgage deals based on your borrowing needs and mortgage interest rates in Ireland.

To get started, select the type of mortgage you’re applying for and enter:

  • the property value
  • your mortgage amount
  • the term over which you’d like to repay your loan

How do mortgage calculators work?

The calculator applies your inputs to a formula to work out your fixed monthly cost.

It converts your annual interest rate into a monthly rate by dividing it by 12 and multiplies your total term in years by 12 to find the total number of monthly payments, and computes the fixed monthly amount needed to clear both the borrowed principal and the accumulated interest by the end of the term.

How do lenders work out your monthly mortgage repayments?

Banks and lenders use several factors to calculate your monthly mortgage repayments.

Your monthly mortgage repayment also varies depending on your credit history and any additional fees or charges.

Factor How it affects your repayment  
The principal (loan amount) The total amount you are borrowing. A larger principal equals higher monthly repayments.  
The loan term The number of years you have to repay the loan (up to 35 years). A longer term lowers your monthly bill, but increases the total interest you pay over the life of the mortgage.  
Interest rate In Ireland, your rate is determined by your Loan-to-Value (LTV) ratio and, sometimes, the property’s energy efficiency. Lower LTVs and A-to-B energy ratings for Green Mortgages unlock the cheapest rates.  
Mortgage type Fixed rates lock in your exact monthly payment for a set period (e.g. 3 to 10 years). Variable rates can rise or fall based on changes in the lender’s or the European Central Bank (ECB) rate.  

Bear in mind that your monthly repayment doesn’t cover the upfront costs of buying a home. You’ll need to budget for stamp duty, solicitor and valuation fees and ongoing mandatory insurance.

Stamp duty calculator

When buying a property in Ireland, you’ll need to pay stamp duty - a government tax on property purchases.

Switcher.ie’s stamp duty calculator helps you estimate how much you’ll owe based on the property price and type. It’s free, quick, and based on the latest Revenue guidelines, so you can get a reliable estimate in seconds.

To find out how much you’ll need to pay, simply enter the value of the property you’re buying and indicate whether or not the property is a new build.

Residential property value

How is stamp duty calculated in Ireland?

When you’re buying a home, stamp duty rates depend on the value of the property. The rates for residential homes in Ireland are:

Property value Stamp Duty rate
First €1,000,000 1%
Portion from €1,000,001 to €1,500,000 2%
Portion above €1,500,000 6%

Mortgage calculator FAQs

What are Ireland's mortgage lending limits in 2026?

Current Central Bank of Ireland Mortgage Limits 2026

Buyer type Max LTI Min deposit
First time buyer 4 x combined income 10%
Second buyer 3.5 x combined income 10%
Buy-to-let investor Not restricted by LTI 30%

How are borrowing limits decided in Ireland?

The Central Bank of Ireland is responsible for lending limits and mortgage measures. These rules are in place to help:

  • Ensure lenders lend responsibly
  • Ensure you borrow what’s affordable
  • Keep the economy stable

How do Irish banks calculate self-employed income?

Lenders do not look at your gross business turnover. Instead, they look at your net profit (sole traders) or director’s remuneration/salary (company directors).

To calculate your maximum loan amount, banks typically use the average of your last two years’ income. If your most recent year’s income dropped, the bank will usually calculate your mortgage based on that lower figure.

Can I get a mortgage exception to borrow more than the normal limit?

Yes. Central Bank of Ireland rules permit lenders to grant Loan-to-Income exceptions for up to 15% of their total lending to both first-time and second-time buyers. These exceptions allow lenders to stretch the 4.0x or 3.5x income multipliers for applicants demonstrating exceptionally strong repayment capacity.

What happens to stamp duty if someone buys multiple properties?

To restrict bulk purchasing in housing developments, Irish Revenue applies a 15% stamp duty rate to purchases of multiple properties. However, apartments are exempt from this rule and remain subject to standard residential rates.

Do I pay stamp duty on my new build home?

Yes, but the tax is calculated strictly on the property’s base price before the 13.5% VAT is applied.

Example: If a new build costs €454,000 including VAT, the stamp duty is calculated on the €400,000 base price.
