See how much a lower rate could save you. Enter your mortgage balance, the years left, your current rate and the new rate you're considering, and the calculator shows the difference each month and over the length of the deal, after any product fee. It works for a remortgage to a new lender or a product transfer with your current one.

These figures are illustrations based on the numbers you enter. They're not a mortgage offer, and the rates available to you will depend on your circumstances and the lender's checks.
Want real rates? We'll compare your lender's offer with the whole market, and there's no fee from us for a product transfer. Speak to an adviser.
Your home may be repossessed if you do not keep up repayments on your mortgage.
If your deal has already ended, you're probably on your lender's standard variable rate (SVR), which is usually much higher than the deals on offer. Even switching to your own lender's new rate can save hundreds of pounds a month. Read about product transfers.
If the saving is small, check the fee. A lower rate with a large product fee can cost more overall than a slightly higher rate with no fee, especially on a smaller mortgage or a shorter deal. Try both in the calculator.
If you want to borrow more or change your term, that usually means a full remortgage or a further advance with your lender. See how remortgaging works.
