Junior ISA

How much could your child's Junior ISA be worth?

Amount you'd like to invest each year (?)

£ or £83.33 per month
3 years

Expected growth rate (?)


About this calculator: This calculator is an example - it doesn’t show what your child’s investments will actually be worth. Remember investments can go down as well as up in value so your child could get back less than you put in.

To make these calculations, we factored in a total of 1.25% in annual charges, but this could be lower or higher depending on the investments you hold. We haven’t factored in inflation.

Tax rules can change and the value of benefits depends on individual circumstances.

The Junior ISA allowance for 2019/20 is £4,368 and for the purposes of this calculator it is assumed to remain at £4,368 until the child reaches 18.
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.
