"Total cost" is the interest you'd pay over the months left on your fix, plus any one-off costs. It doesn't count the part of your payments that reduces your balance, because you'd repay that either way. It assumes your new rate stays the same for at least that long. Repayment mortgage. Illustrative only.

Before you decide

  • Ask your lender for an exact redemption figure. It shows the early repayment charge in pounds.
  • Check whether the new deal really has the fees you've entered, and whether any are refundable if it doesn't go ahead.
  • Rates can change before your new deal is agreed, and the lender will need to check you can afford it.
  • MoneyHelper notes that on a small balance, the savings from switching might be too low to make it worthwhile.

This calculator shows figures based on what you enter. It isn't a recommendation to switch or to stay. For a personal recommendation, speak to an FCA-authorised mortgage adviser.

Early repayment charge: common questions

What is an early repayment charge?

It's a fee your lender may charge if you leave a fixed or discounted deal before it ends. MoneyHelper says that if you're not at the end of your fixed or discount rate term, you might have to pay one. The details are in your mortgage paperwork, and your lender can give you an exact figure.

Is it ever worth paying an early repayment charge?

Sometimes, on the figures. If a new deal's rate is low enough, the interest you'd save could be more than the charge and fees, but often it isn't. This calculator shows which costs less on the numbers you enter. It isn't a recommendation, and an FCA-authorised adviser can look at your whole situation.

What is the break-even point?

It's how many months it would take for the interest you'd save on the lower rate to cover the early repayment charge and fees. If the break-even point is later than the date your current fix ends, switching early costs more on these figures.

What about overpaying instead?

MoneyHelper says many fixed-rate deals let you overpay up to 10% a year without a fee. Overpaying within your allowance can reduce the interest you pay without leaving your deal. Check your mortgage terms for your exact limit. Our overpayment calculator shows what overpaying could save.

Does this include everything?

No. It's an illustration based on your own figures. It assumes a repayment mortgage and that the new rate stays the same for at least as long as your current fix has left. It doesn't include changes to your term, porting, or rate changes before a new deal is agreed.
