ISA Investment calculator

This calculator is designed to show how putting your money into an Aviva Stocks & Shares ISA could help you to achieve your investment goal.

The results are based on the figures you put in and the options you choose. They are only intended to give you an indication of possible returns and are not guaranteed. Investment returns can go down as well as up and you may get back less than you invest.

This calculator does not provide personal advice or recommendations. If you are unsure whether this product is right for you, you should speak to a financial adviser. You can find one in your local area at


Amount paid in this tax year

This is any amount you have already paid into an ISA this tax year.

Amount paid before this tax year

This is any amount you currently hold in an ISA with any provider previous to this tax year.

Existing ISA investments

The calculator puts all of your ISA investments (existing and current) together and applies the same level of charges and rates of growth to the combined total. Please be aware that if your ISA investments are held in different places, they are likely to have different charges and grow at different rates, so the result can only ever be an indication of what might happen. Also, if any of your investments are in cash ISAs, they are unlikely to have the same growth potential as investments in stocks and shares ISAs and the calculator may produce an over-estimation.

Expected rate of growth

"This is the annual rate of growth anticipated. Whilst we have set the default to 5%, this shouldn't be seen as an average, or in any way guaranteed. Investment returns cannot be predicted and may be higher or lower than this. You can change the expected rate of growth to see how different level of investment return could affect what you get back."
