How Mortgage Repayments are Calculated in Ireland
Mortgage repayments in Ireland are calculated based on your principal (loan amount), the annual interest rate (AIR), and the term of the loan. Most Irish mortgages are "annuity" mortgages, meaning your monthly payment repays both the interest and a portion of the original capital.
Central Bank of Ireland Lending Rules
If you are a first-time buyer in Ireland, the Central Bank allows you to borrow up to 4 times your gross annual income. You will also need a minimum deposit of 10% of the property value. Second and subsequent buyers are also restricted to 4 times their income and a 10% deposit.
Key Factors Affecting Your Repayment:
- Interest Rate: Rates vary by provider (e.g., AIB, Bank of Ireland, PTSB). Even a 0.5% reduction can save thousands over the term. Consider comparing fixed vs variable rates.
- Term Length: Longer terms (e.g., 35 years) reduce monthly costs but increase the total interest paid significantly. Our amortization chart visually demonstrates this.
- BER / Green Rates: Properties with an A-C BER rating often qualify for lower "Green" interest rates, saving you substantial amounts in interest over the lifetime of the loan.
Don't Forget About Extra Costs
Calculating your mortgage is just step one. Don't forget to budget for Stamp Duty, legal fees, valuations, and life assurance. First-time buyers of new builds might also qualify for the Help to Buy (HTB) scheme, which can grant up to €30,000 towards your deposit.
