Junior ISA calculator: what could your child's ISA be worth in the future?

ISA calculator

This simple online Junior ISA calculator provides you with an illustration of how much your child's ISA investments could be worth in the future when they reach 18 using this important tax wrapper.

Within a Junior Stocks & Shares ISA you will benefit from:

  • Tax free growth
  • No UK income tax payable on your child's investments

This tax year (2016/2017) you can subscribe a maximum of £4,080 into the Junior ISA. This equates to a regular investment of £340 per month for 12 months.

Please note that this calculator is an illustration and not a projection of what your investments will be worth. The annual growth rate achieved will depend on the performance of the investments chosen. Results do not take account of inflation or charges.

Remember the value of investments can fall as well as rise so your child could get back less than you invest. Tax rules can change and the value of any benefits depend on your child's circumstances.
