Remortgage Calculator

Once your discount, tracker or fixed-rate mortgage ends, you’ll be moved onto your lender’s 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.

We need a few details about your mortgage

If you’re not sure about these, you can find them on your most recent mortgage statement.

How much can I remortgage my house for?

You can usually borrow the outstanding amount owed on your mortgage if you’re switching to a new deal. Or you might want to borrow more to release the equity tied up in your home.

Either way, lenders will treat your remortgage as a new mortgage application. When deciding how much you can remortgage for, they’ll consider a few factors, including:

  • The current market value of your property
  • Your financial circumstances, including your credit score, monthly income and outgoings
  • Your loan-to-value ratio (LTV) – the amount you want to borrow as a percentage of the property’s value.

How does the remortgage calculator work?

Once your current mortgage deal comes to an end, your rate will change to your lender’s standard variable rate (SVR). We’ve calculated how much you could pay if you don’t remortgage before you change to a lender’s typical SVR of 8.20%[1].

Our tool makes this calculation based on your outstanding mortgage balance, the time left before your mortgage is completely paid off and the discounted rate you received in those first few years.

[1] This Standard Variable Rate is the average SVR from our top 6 lenders on March 28 2024.

Frequently asked questions

Is it worth remortgaging?

Remortgaging to a better deal could potentially save you thousands of pounds. It might be worth remortgaging for the following reasons:

  • Your current deal is coming to an end and you can find a better rate than your lender’s SVR
  • You want to overpay on your mortgage so you can pay it off sooner
  • You want to remortgage to release equity for home improvements
  • Your property’s value has increased significantly, so you may be in a lower LTV band and eligible for a better interest rate.

How much can you save by remortgaging?

The actual amount you’ll save depends on your outstanding mortgage balance, the mortgage rate and the length of term. You’ll need to consider these factors when taking out a mortgage or remortgaging to a new deal.

Can I remortgage early?

Yes, you should be able to remortgage whenever you like. However, if you remortgage early, before your current agreement is due to end, you’ll most likely have to pay an early repayment charge. This is normally a percentage of the outstanding mortgage balance.

Who can remortgage?

As a homeowner, you should be able to remortgage at any time, but it can depend on your financial circumstances. Usually, it’s best to wait until your current deal is coming to an end.

You might also be able to remortgage if you’re mortgage-free and own your home outright. Again, it depends on your current financial situation.

If you feel your financial situation could make remortgaging complicated, we’ve partnered with London & Country Mortgages Ltd (L&C)** to provide you with fee-free mortgage advice. They can help you find the right option.

 

How long does it take to remortgage?

The remortgaging process typically takes around four to eight weeks to complete, although a simple switch of rate with your existing lender for the same balance can be done in less than a day.

It can take longer if you’re looking to borrow more or release equity, 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.

How can I find the best interest rate when I remortgage?

There’s a few things you can do to help you find the best interest rate:

  • Improve your credit score – a higher credit score could give you access to better deals.
  • Reduce your LTV – if you’re in a lower loan-to-value band, you can often find cheaper remortgage deals.
  • Build up a steady employment record – lenders like stability and a steady income.
  • Compare deals – save time by comparing a wide range of mortgage deals through Comparethemarket.
