Child ISA is another name for a Junior ISA (also sometimes known as a children’s ISA) which offers tax-free savings for UK residents under the age of 18. For the 2017/18 tax-year, you can save up to £4,128 in a Junior ISA without paying tax on the interest you earn.

Our free child ISA calculator allows you to quickly see how much you or your child could save with a tax-free Junior ISA. You can see what impact putting different amounts into the ISA will have, as well as how much difference various interest rates and the length of time the ISA lasts will make.

With so many different ISA providers and types of ISAs to choose from, our quick, simple ISA comparison tool makes it much easier to make the right choice for your savings.

Using our Junior ISA calculator to compare ISA deals for children

Our child ISA calculator lets you compare the effect of three different things on the return you can expect on your junior ISA:

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

This means if you have a specific amount you are intending to save, you can see how much this will earn you over the period you want to save for. Alternatively, if you are aiming to build a specific amount, the calculator can let you see how much you need to save, how long for and what sort of interest rate you will need to achieve your savings goals.

How accurate is our children’s ISA calculator?

The growth projected by the calculator is only an estimate, as interest rates will tend to vary over time. The figure we suggest should therefore not be taken as a definite prediction.

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
