Online affordability calculator

Applications will be accepted for up to four applicants. If there are more than two applicants please input the details of the two highest wage earners only.

A dependant is a person who is not named on the mortgage but is supported financially by someone who is.

When selecting interest only, we will assess that you can afford the loan on a capital and interest basis over a default term of 25 years (or lower if requested). E.g. if you select 30 years, then the calculation will be carried out over 25 years.

If you require part and part repayment method then affordability will be calculated on a repayment basis on the term selected.

Purchase - You intend to buy a property (not the one you are currently living in unless this is under a Right to Buy scheme).

Remortgage - You intend taking out a new mortgage with Northern Rock, on the same property you are currently living in, to raise capital or to repay your existing lender.

The maximum amount you are able to borrow is restricted to the loan to value percentage of the mortgage product.

Loan to value is the ratio between the size of the loan you are looking for and the value of the property you are buying. For instance, if you're borrowing £70,000 on a property valued at £100,000, the LTV is 70%.
