Mortgage Repayment Calculator Ireland

Model repayments, rate changes and Central Bank lending limits. This free mortgage repayment calculator ireland shows the calculation and its assumptions so you can compare your own figures.

How the mortgage & borrowing limits calculation works

Monthly capital-and-interest amortisation is recalculated when the interest rate changes. Overpayments reduce the remaining balance.

Standard LTI is 4× for first-time buyers and 3.5× for subsequent buyers. Owner-occupier minimum deposit is generally 10%; buy-to-let 30%. Allowances, exempt loans and lender affordability assessments are separate.
