Important information: this calculator is just an illustration, not a projection of what your child’s investments will be worth. The annual growth rate actually achieved will depend on the investments chosen. Results are calculated with an assumed annual charge of 1.25% (based on our platform charge and a typical fund annual charge). The actual charges could be higher or lower than this, please see our Junior ISA Charges page for more details. They do not take account of inflation, which will reduce the amount of goods and services money can buy in the future.

Remember the value of investments can fall as well as rise so your child could get back less than invested. Tax rules can change and the value of benefits available depends on individual circumstances.

This is the annual growth rate you anticipate on your child's investments. This rate is not guaranteed – the value of investments can rise and fall so your child could get back less than invested.
For children born between 1 September 2002 and 2 January 2011, parents will need to transfer their Child Trust Fund (if they haven’t done so already) to open a Junior ISA.
