Switcher mortgage calculator


With our switching mortgage calculator it’s easy to find out how much you could save. Answer a few simple questions and in less than one minute we’ll calculate the monthly and overall savings you could make by switching your mortgage to the best available rate available to you.

You’ll need:

  • Estimated value of your home
  • Balance on your existing mortgage
  • Remaining term
  • Current mortgage rate

Then we’ll give you an Approval in Principle figure of how much we could lend you and how much your monthly mortgage repayments might be. Of course, this isn’t a loan yet as we’ll need to confirm some things before we actually lend you the money. 

Switch your mortgage to us and we'll give you €3,000 to help cover your costs. We’ll pay it into the current account you use to pay the mortgage from, even if that current account is with another bank. The AIB €3,000 switcher payment is available for Private Dwelling House (PDH) mortgages only, switching to Fixed or Variable rates.
