Mortgage Calculator
Monthly repayments, total interest and schedule — annuity or reducing payments. Free, no sign-up, works in your browser.
Estimates only — not financial advice. Your lender’s figures (fees, insurance, rate changes) will differ. In Ireland first-time buyers usually need at least a 10% deposit and can borrow up to 4× income under Central Bank rules.
🔒 100% private — processing happens in your browser. Nothing is uploaded.
How to use the mortgage calculator
- Enter the property price, your deposit, the interest rate and the term.
- Choose annuity (the same payment every month — standard in Ireland and the UK) or differentiated (equal principal, payments fall over time).
- Add an extra monthly overpayment to see how many years and how much interest it saves; check the yearly schedule and chart.
Small changes in the rate or term make a big difference over 25–35 years. Overpaying even €100 a month can cut years off a mortgage — check that your lender allows it without penalty (most variable-rate mortgages do; fixed rates often limit overpayments). The calculator works for any currency and for car or personal loans too; for those see also our Loan Calculator.
