The Junior ISA Calculator

The figures shown are only examples and are not guaranteed, such forecasts are not a reliable indication of future performance. They are not minimum or maximum amounts. What you get back will depend on how your investments grow, how much you invest and will depend on the charges incorporated for your investments. You could get back more or less than the calculator indicates. Please note that inflation will reduce what you can buy in the future with the amounts shown.

The value of investments can fall as well as rise so your child may get back less than you invest. Tax savings and eligibility to invest in a Junior ISA will depend on personal circumstances and all tax rules may change in future. Fidelity does not give advice, for all recommendations contact an authorised financial adviser.

A Junior ISA is only available to children under the age of 18 who are resident in the UK. It is not possible to hold both a Junior ISA and a Child Trust Fund (CTF). If your child was born between 1 September 2002 and 2 January 2011 the Government would have automatically opened a CTF on your child's behalf. If your child holds a CTF they can transfer the investment into a Junior ISA. Please note that Fidelity does not allow for CTF transfers into a Junior ISA. Parents or guardians can open the Junior ISA and manage the account but the money belongs to the child and the investment is locked away until the child reaches 18 years old.
