Remortgage Calculator

Once your discount, tracker or fixed-rate mortgage ends, you’ll land on a standard rate which can cost much more each month. Use our remortgage calculator to find out how much this could cost you, if you don’t make the right switch.

Your home or property may be repossessed if you do not keep up repayments on a mortgage.

Frequently asked questions

How do I use the remortgage calculator?

Our remortgage calculator is designed to be as simple as possible. Simply enter a few of your details and we’ll take care of all the hard work and boring sums. Here’s what we’ll need from you:

  • The term left on your mortgage in years
  • Your outstanding mortgage balance
  • Your current monthly repayment amount
  • Your current mortgage rate

And that’s it. With those few details, we can quickly work out how much more you could end up paying if you don’t remortgage before your current deal ends.

Who can remortgage?

It depends on your individual financial circumstances, but you may be able to remortgage if your current deal is coming to an end.

You can still remortgage if you’re in the middle of a fixed-term mortgage deal. However if you’re still quite far from the end of your fixed term, it may not be your best option, as your current deal will likely have an expensive early repayment charge tied to it, which may outweigh any potential savings you could make.

Remortgaging after retirement age (usually over 60), used to be difficult, as lenders are more hesitant to lend to people who are no longer working. However, retirement interest-only (RIO) mortgages are now more accessible. Your potential lender will still run a series of affordability checks, but as long as you can prove you’ll be able to meet your repayments, you could still find a new deal.

Even if you own your home outright, you may be able to remortgage.

If you feel your financial situation may make remortgaging complicated, talk to our partnered mortgage advisers from London & Country Mortgages Ltd. free of charge. They can help you find the right option for you.

How long does remortgaging take?

It depends on how and why you’re remortgaging, but a simple switch of rate with your existing lender for the same balance can be done in less than a day. If you’re looking to borrow more or release equity, this can take longer, as the terms of your mortgage will change more significantly.

If you’re remortgaging with a different lender, this can also take longer, because you’ll need to go through the full application process as a new customer. This will involve affordability checks, valuations and other legal processes.

It’s important that you leave enough time before your existing deal ends, as leaving it too late could see you slip onto the more expensive standard variable rate for a few months. Most lenders will let you apply for a rate between three and six months before your current deal ends.

How is this figure calculated?

When you took out your mortgage, you probably got a discount, tracker or fixed-rate deal, which is better than the standard variable rate (SVR), for the first few years. At the end of this term, your rate will change to your lender’s SVR. With our tool, we’ve used your outstanding mortgage balance, the time left before your mortgage is completely paid off, and the discounted rate you got in those first few years, to calculate how much more it’ll cost you if you don’t remortgage before you change to a lender’s typical SVR of 3.59%.

Why should I consider remortgaging?

There are three main reasons why you may consider remortgaging your home.

1. Getting a better deal and saving money each month
If your existing mortgage deal is coming to an end, your lender will put you onto their standard variable rate. This is usually the worst place to be, as it tends to offer the highest rates. Before you end up on that higher rate, compare remortgage deals to find a better rate and save money each month for exactly the same home.

2. Make changes to how you repay your mortgage
By remortgaging to a new deal, you can make changes to how your mortgage works. You will be able to easily switch from interest-only to a repayment mortgage. However, you won’t be able to switch from repayment to interest-only, unless you can demonstrate that you have a credible repayment method to pay off the loan at the end of term. You could add the flexibility to overpay on your mortgage, whether that’s with any leftover money you don’t spend each month, or if you come into a sudden windfall. You can also reduce or extend your mortgage term, allowing you to either pay off your mortgage sooner, or extend it to lower your monthly repayments.

3. Release equity to access money
If you need access to a large sum quickly, remortgaging to release equity in your home is one way of doing so. A common reason for doing this is to fund an extension or other home improvements. By releasing equity, you’re essentially selling a portion of your home back to your provider, which will mean that your outstanding mortgage balance will increase, which will also see your monthly repayments become more expensive.

A study for NatWest bank found that three quarters of homeowners feel remortgaging had a positive impact on their life overall.

  • 43% of people say remortgaging had a positive impact on their mental health – with a further 23% saying it improved their wellbeing and reduced stress
  • For 8% of people, remortgaging was necessary due to COVID-19 – and a further 8% remortgaged because of stress and anxiety caused by the pandemic
  • Three in five people say they’d consider remortgaging again to fund home improvements.

Give yourself plenty of time to complete remortgage process

Experts say they’re experiencing delays in mortgage processing – making it more important than ever to begin in good time. To help ensure a smooth switch, get together all the paperwork required by the lender ahead of time.
