Affordability calculator

Please note:

  • when applying for a remortgage on a like for like basis, the calculator will return the affordable amount, subject to a maximum of the amount transferred from the existing lender plus £1,000.
  • don't use this calculator if your clients are remortgaging on a like for like basis and own more than one mortgaged property.

Instead, complete a Decision in Principle in NFI Online where you’ll get an accurate affordability amount and a list of documents required.

For a thorough calculation of how much your client may be able to borrow, fill in the full affordability calculator below.

Alternatively, for straightforward cases you can get a quick indication of how much Nationwide could lend by using the quick quote calculator on nationwide.co.uk.

To give your client(s) an estimate of how much their property is worth today, use the house price calculator.

Both calculators are for illustrative purposes and we recommend you complete the full affordability calculator before moving to a Decision in Principle (DIP). The quick quote calculator isn't recommended for self-employed applicants or non-standard transactions.
