Assumptions

What this calculator does

It estimates wrapper-level Junior ISA platform, trading, and FX costs. Fee drag assumes 5% annual growth. A monthly contribution is modelled as one monthly trade for each selected investment type.

If "buy only US stocks" is checked, the monthly contribution is also modelled as monthly FX conversion. The current Junior ISA allowance used for warnings is £9,000.

Product-level fund charges, spreads, tax rules, cash interest, transfer fees, and investment performance are outside this model.

Educational fee comparison only. This is not financial advice, tax advice, or a recommendation to open or transfer a Junior ISA.
