Using our free ISA interest calculator, you can see how much you could grow your savings with a Nationwide ISA.

The calculator shows how much interest you might earn with different ISAs, based on how much you deposit, the interest rate offered and how long you want to save for.

This provides valuable guidance when deciding how to use your tax-free ISA allowance, which for the 2017/18 tax year is £20,000 (or £4,128 for a Junior ISA).

Compare Nationwide ISA deals

Nationwide is one of a number of different ISA providers, so to make sure you are getting the best deal with your savings it is sensible to compare as many different ISA products as possible. Our free ISA interest calculator makes this as simple as possible.

The calculator lets you see the effect of three different factors:

  • Amount saved
  • Interest rate earned
  • Length of time saved for

This allows you to see how much you will need to deposit into different ISAs to achieve a specific savings goal, or how much you could generate based on the amount you want to deposit each month.

How does our ISA calculator work?

Our calculator gives an estimate of the total growth you may achieve based on the figures you provide. This estimate is for guidance purposes only and the actual amount of growth you see will depend on how interest rates change over time.

Our estimate assumes the following:

  • You will deposit money into your account on a regular basis
  • There will be no withdrawals made
  • The market will stay broadly steady
  • Interest rates will remain productive
  • There will be no reduction in the ISA tax-free savings allowance during the term of your account
