Stocks and Shares ISA Calculator

Our ISA calculator can help you understand how much your savings could grow when saving with a Stocks and Shares ISA.

Important information: The value of your investments and the income from them and can go down as well as up, so you may get back less than you invest. Tax treatment depends on individual circumstances and all tax rules may change in the future. This information is not a personal recommendation for any particular investment. If you are unsure about the suitability of an investment you should speak to an authorised financial adviser.

How the ISA calculator works

The forecast from this calculator is based on your input and is not a reliable indicator of future results. It will therefore not show what your investments will actually be worth. The growth figures shown assume annual charges of 1.1% and are net of these charges.

When using this tool, you need to select the rate of growth that you would like to see a projection for. Fidelity can’t advise you as to what a reasonable rate of growth would be for your investments - it depends on a number of different factors.

See more on how this is calculated

Enter any single payments which you’re planning to make in the current tax year.

Enter the value of any existing ISAs you hold which you want the projection to take into account.

Select an example growth rate to see how well your investment might grow during the time period you have selected. But remember that these figures are based on your input and do not reflect what you will actually receive.
