Important Information: * The return of your initial deposit depends on the ability of the deposit taker (Investec Bank plc) to repay your money. Structured deposits offer you the potential to earn higher returns than you would with a regular savings account. Your returns are based on the performance of an index or commodity. If the investment does not perform well you may receive no income or capital growth, but you can be confident that your capital will be repaid. You have no access to your deposit during the term of the account, typically 3 to 6 years but your original capital will be repaid in full at the end of the term. In the event that the deposit taker is unable to repay your initial investment and any returns stated you may be entitled to compensation from the Financial Services Compensation Scheme (FSCS) depending on your individual circumstances.

Savings Focus: a potential 5.0% from your savings...

Although inflation over the last couple of months has fallen slightly to 2.50%, this is still much higher than you can get from many traditional savings products, such as fixed rate bonds. And if you take a look at the range of Cash ISA rates on offer, the options are even worse as these savings rates are generally much lower than their non-ISA equivalents.

Against this challenging environment for savers, the Deposit Kick Out Plan from Investec Bank has proved to be popular choice with a wide range of our new and existing savers.

By linking your return to the FTSE 100 Index, this plan offers a potential 5.0% per year (not compounded). Although it has a maximum term of six years, it will ‘kick out’ early provided the value of the FTSE 100 Index at the end of each year from year 3 onwards, is higher than its value at the start of the plan. That’s a potential 15% after three years, 20% after four years, etc.

The plan is deposit based and so offers the same FSCS protection as a normal fixed rate bond, but since the rate is not guaranteed, it should be considered as an alternative to traditional savings products. With this in mind, if you think savings rates will remain at their current historical lows, alternatives such as these might well be worth a  closer look…


What is a cash ISA?

A cash Individual Savings Account (ISA) is a tax-free savings account which allows you to save up to a set amount of money per financial year without paying any tax on it,  you can check the current cash ISA limit by clicking here. You need to be a UK resident or Crown employee aged 16 or over to open an account. You can only have one cash ISA per tax year, but you can also have a different type of ISA, known as a  stocks and shares ISA, simultaneously.

Benefits of a cash ISA

There are three key benefits to a cash ISA:

  • No income tax - you don't pay tax on any interest you earn from the cash in your ISA.
  • Easy access - if you choose an instant access cash ISA (rather than a fixed-rate cash ISA) it's a convenient way to save at a good interest rate while retaining fast and easy access to your money, should you need it.
  • Easy transfers - if you find an ISA provider that offers a better deal than your current provider, you can transfer your cash ISA to them.

How much tax can I save with a cash ISA?

The good news is that whatever your tax bracket, you'll pay 0% tax on any savings held in a cash ISA. Compare this to the usual tax rates on savings:

If you're a basic rate taxpayer...
you would usually pay 20% tax on interest earned from savings.

If you're a higher rate taxpayer...
you would usually pay 40% tax on interest earned from savings.

If you pay tax at the additional higher rate...
you would usually pay 50% tax on interest earned from savings.

If you pay the 'savings rate' of tax for savings...
you would usually pay 10% tax on interest earned from savings.

Using your cash ISA allowance can therefore save you money by allowing you to keep 100% of any interest you earn.

The above information gives you a general idea of what you could save - remember that it depends on your individual circumstances and may be subject to change in the future.

Can I transfer a cash ISA?

It depends on your circumstances. If you've got some money saved as a lump sum from a previous tax year, you'll usually be permitted to transfer this from one cash ISA to another, or to a stocks and shares ISA. This transfer shouldn't affect your ISA investment allowance for the current tax year.

Which type of cash ISA is right for me?

An instant access cash ISA might be the right choice for you if...

  • You want a good rate of interest, plus the ability to get hold of your money quickly if necessary.
  • You want to take advantage of your annual tax-free savings allowance but only have a small amount to deposit - instant access ISAs can be opened from as little as £1.
  • You want to be paid regular interest - instant access ISAs usually offer monthly or quarterly interest.

A fixed-rate cash ISA might be right for you if...

  • You are happy to put your money aside for a set period of time - this usually allows you to accrue a higher rate of interest than you might get with an instant access cash ISA.
  • You want to take advantage of your tax-free savings allowance and have a lump sum to deposit - many fixed-rate cash ISAs require an initial deposit of around £1000.

Top tips for making the most of your cash ISA

  • You can only have one type of cash ISA in each financial year, so research your options carefully. Whether you choose a fixed-rate or instant access cash ISA, give some thought to your savings goals beforehand to help you determine what's right for you.
  • Remember that you can't carry your tax-free allowance over from one financial year to the next - so if you've got enough cash to hit your limit, stash it in an ISA. 
  • Because a cash ISA operates on a year-long basis, it's a good way to try your hand at saving without committing yourself to anything long-term. It's also a great way to save for a specific event like a wedding, holiday, or starting a family.
  • Once you've set up your cash ISA, make sure you still keep an eye on the interest rates available from other providers. You can usually switch cash ISA providers without incurring any charge.
  • To make life easier, set up a direct transfer from your current account into your cash ISA to make sure that you put aside a certain amount each month without fail.
  • Don't forget that you've got the option of opening a stocks and shares ISA, too. For more on this, see our page on stocks and shares ISAs.
