The amounts shown are for illustrative purposes only. They are not guaranteed returns. The projected investment returns are for a medium risk investment fund. Amounts for lower or higher risk investment funds will be different. As the figures show, investments can go down and up. You may get back less than the full amount you put in. Forecasts and past performance don't guarantee performance trends of future returns. Inflation will reduce the spending power of any money you get back.

Investments

If you’re new to investing or have some experience, invest in a way that suits you

Savings and ISAs

Our range of savings accounts and cash ISAs can help you plan for your future

Investments should be held for the medium-long term (5+ years) to give your money the best chance of growing. It’s a good idea to have other savings in place. This is in case the market falls. You won’t have to dip into your investments to cover any unexpected costs and can leave them to recover.

Saving growth

This is based on our current Easy Access ISA interest rate.

When you put in the amount you want to save, we'll add interest based on how long you’d like it to stay in the account. We use our current interest rate to give you an idea. Interest will be paid tax free. The tax free rate is the rate of interest payable where interest is exempt from income tax.

Investing growth

To understand the projected returns, we’ve selected the yearly rates that apply for the term with the highest chance for loss, based on the latest market trends. This doesn't show a guarantee of the performance for the potential low, realistic or high returns.

  • Potential high: Shows the expected return in strong investment conditions. 
  • Potential low: Shows the expected return in weak investment conditions. 
  • Realistic: Shows the return, which has a 50% chance of being better or worse than this (in other words, the median return).

All figures allow for the platform services fee, fund fees and asset allocation of a Santander fund. This is typical of the medium-risk category. Please bear in mind that we’ve not added any potential tax that could be payable on any returns.
