Estimate how your investments could perform using our calculator below

This calculator shows what your investment could be worth over time based on different levels of growth, it is not an indication of future performance. We can't tell you how your investment will actually perform as it will depend on the actual growth rates achieved as well as the ongoing charges.

These results do not take inflation into account, so remember in the future this means you wouldn’t be able to buy as much with the amounts shown as you can today.

The calculations are not guaranteed and investments can go down as well as up in value along with any income from them, so you could get back less than you originally invested.

These calculations are for illustration purposes and are not guaranteed.

The total charges assumed in the calculations above are 1.22% per year.

We have assumed average total charges of 1.22% per year within the calculator.  This is made up of the Investment Hub Platform Service Fee at its maximum level of 0.35% per year, plus an assumed total fund charge of 0.87% per year. This is the average fund charge for a Santander Asset Management (UK) Fund. It is important to check the actual charges for an individual fund as well as the Platform Service Fee that applies to your level of investment. There is a reduction in the Platform Service Fee when the value of your investments are above £50,000. 

We have assumed monthly payments are received in advance.

This calculator does not take into account any potential tax that may be payable on the returns you receive and does not provide any advice. If you are unsure what level of returns you would need, you should speak to a financial adviser, before making any decisions.

Remember, the more risk you are prepared to take, the more chance you have of achieving higher investment performance. However this could also increase the volatility of the value of your investments and your chance of losing your money.

Important Information

Please remember the value of your investments and any income from them can go down as well as up and you may get back less than the full amount you invest. When you invest you should be prepared to have your money invested for the medium to long term, typically at least 5 years.
With traditional savings your capital will grow when interest is added, however over time the real value will be affected by inflation. With investments, your capital isn’t guaranteed to grow, however they have more potential to balance the effects of inflation.
The tax treatment of your savings and investments, including the favourable tax treatment of ISAs, may be subject to change in the future and depends on your individual circumstances.
