How to compare different mortgage rates

Whether your existing mortgage deal is coming to an end soon and you want to consider all your remortgage options or you’re moving house, it’s important to compare the effect different mortgage interest rates could have on your monthly outgoings.

Using our mortgage difference calculator above is a great starting point as it will give you an initial snapshot of how things could change, particularly if interest rates continue to rise for the foreseeable future.

Once you’ve used the calculator, the smart next step would be to seek the help of an experienced mortgage broker. They’ll be able to go into more detail about the cheapest mortgage deals available, comparing variable rates versus fixed-rate mortgage options to see which best suits your circumstances.

How this calculator works

Our mortgage difference calculator is very simple and straightforward to use. All you need to do is input:

  • Your loan amount (this can be for either a new mortgage or existing balance if you’re remortgaging)
  • Loan term (input your remaining term if for remortgaging purposes)
  • Current interest rate and new interest rate

And that’s it! The calculator will then illustrate what this difference could mean in terms of both a monthly increase and overall mortgage payments.

If you’re unsure what your new interest rate could be you can re-input as many times as you like, selecting different rates so you can see a range of scenarios and potential outcomes.

What you should do next

FAQs

This all depends on your personal preference and circumstances. At the time of writing (March 2023) most 2-year options are actually more expensive than 5-years. This is likely down to most mortgage lenders expecting rates to eventually come back down during this period.

So, a 5-year option would likely represent cheaper repayments but over a longer term, which means it may work out more expensive overall. Speak to your mortgage broker and they will be able to provide advice on which option may suit you best, based on your required needs.
