Mortgage overpayment calculator

Find out how much you could save by overpaying on your mortgage

How much can I save if I overpay?

At Sainsbury’s Bank, we allow you to make overpayments on all our mortgages so you can save money by paying it off quicker. Whether you’ve got a bit of extra money each month or have some savings you want to use, your mortgage overpayments can be set up as regular payments or a single lump sum. Conditions apply flexible payment options.

The calculator is for illustrative purposes only. It does not take into account any restrictions or early repayment charges. The tool assumes the mortgage rate used applies to the term stated, so cannot account for changes to your product or interest rates.

What type of overpayment would you like to make?

During your initial rate period, you can overpay by up to 10% of what's left on your mortgage without paying any charges. The first 12 month allowance period will begin from the completion date of the original mortgage and refresh on every anniversary thereafter. But if you overpay by more than 10%, you’ll pay a charge on the amount that's over that initial 10%. Conditions apply flexible payment options.

You can find the full details of our overpayment facility in your mortgage offer and in our Residential terms and conditions and Buy To Let terms and conditions. To speak to one of our experts, or if you wish to make an overpayment, please give us a call on 0345 111 8020**
