The value of your investment can go down as well as up and you may get back less than you paid in. Laws and tax rules may change in the future. Your own circumstances and where you live in the UK also have an impact on tax treatment.

How our ISA Calculator works

ISAs can be a tax-efficient way for you to save money and to invest in Stocks & Shares.

But how much could your savings be worth in the future? Our quick and easy ISA calculator can give you an idea of how much your money could be worth over the next five years. Keep in mind that growth is an assumption and doesn’t reflect how your money will perform.
