What Nationwide says about the yearly allowance

Nationwide says some of its mortgages have an overpayment allowance and that you may have to pay an early repayment charge if you go over it. Its table sets the allowance by product type and the date the product was reserved.

Some of our mortgages have limits, known as an allowance, on how much you can overpay. If you go over this allowance, you may have to pay an Early Repayment Charge (ERC).

All tracker mortgages reserved on or after 2 May 2014: Unlimited

How Nationwide applies overpayments

Nationwide says it calculates interest daily, so an overpayment reduces the interest you pay from the following day, and that you can tell it how you want your overpayment money to be used, for example to reduce monthly payments, reduce term (excluding interest only) or keep both the payments and term the same.

We calculate the interest on your mortgage daily so all overpayments will reduce the interest you pay the following day.

You are in control of your overpayment preferences - you can tell us how you want your overpayment money to be used to best suit your individual mortgage needs. For example, reduce monthly payments, reduce term (excluding interest only) or keep both the payments and term the same.
