Ireland Mortgage Repayment Calculator
Estimate only. Actual lender quotes can differ based on APRC, insurance, and fees.
How to use this Ireland mortgage calculator
This calculator helps you estimate mortgage repayments for a home in Ireland. Enter your property price, deposit, annual interest rate, and term length. It then calculates your expected repayment amount and gives you a clear summary of total interest, total amount paid, and loan-to-value (LTV).
- Property Price: The agreed purchase price of the home.
- Deposit: The amount you pay upfront from savings.
- Interest Rate: Your expected annual mortgage rate.
- Term: How many years you plan to repay the mortgage.
- Overpayment: Optional extra amount each period to reduce total interest and shorten the term.
What this calculator includes
The calculation uses a standard repayment mortgage model (capital + interest), which is the most common mortgage structure for owner-occupiers in Ireland. It also includes a simple stress-test repayment at +2% interest so you can see how sensitive your monthly cost is to rate increases.
Useful outputs
- Expected regular repayment
- Total interest over the life of the loan
- Total repayment amount
- LTV (Loan to Value)
- Impact of overpayments on time and interest
Ireland mortgage rules at a glance
Irish mortgage rules are set under Central Bank lending limits. These can change over time, and lenders can apply policy exceptions, so always verify current details before making decisions.
Loan-to-value (LTV)
LTV compares your mortgage amount to your property value. A lower LTV generally improves your mortgage options and can help you access better interest rates.
Loan-to-income (LTI)
LTI limits how much you can borrow compared with gross annual income. Lenders typically apply standard LTI limits with some flexibility through exemptions. If you are close to your borrowing cap, improving deposit size can make a major difference.
Other home-buying costs in Ireland
Your mortgage repayment is only one part of the total cost of buying a property. Budget for:
- Stamp duty
- Solicitor/conveyancing fees
- Valuation and survey costs
- Home insurance and mortgage protection insurance
- Potential maintenance and moving costs
Fixed vs variable mortgage rates
Fixed rate
Your repayment stays predictable during the fixed period, which can make budgeting easier.
Variable rate
Your repayment may rise or fall over time. This can be beneficial if rates drop, but it carries uncertainty.
Example scenario
If you buy a home for €350,000 with a €50,000 deposit, your estimated loan is €300,000. At a 4.25% rate over 30 years, the monthly repayment is typically in the low-to-mid €1,000s. Adding even €100 extra per month can reduce interest significantly and shorten the repayment period.
Practical tips to reduce mortgage cost
- Increase deposit where possible to reduce borrowing and LTV.
- Compare APRC rather than headline interest rate alone.
- Review break fees before switching from fixed products.
- Use regular overpayments if your lender allows penalty-free reductions.
- Reassess your mortgage every few years for switching opportunities.
Frequently asked questions
Is this calculator exact?
No. It is a planning tool. Lender underwriting, rate type, fees, and insurance will affect final figures.
Does it include insurance?
No. Mortgage protection and home insurance are not included in repayment outputs.
Can I use this for buy-to-let?
You can use it for repayment estimates, but buy-to-let lending rules and pricing are often different from owner-occupier mortgages.
