ISA Option
Maximum Potential Return 7.00% pa or 2 x FTSE growth

Important Information: * The return of your initial deposit depends on the ability of the deposit taker (Goldman Sachs) 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.

FTSE 100 6 Year Deposit Plan

from Investec

ISA Option
Maximum Potential Return 42.00% at end of term
  • Deposit Taker: Investec Bank plc
  • Term: 6 years

"This plan offers a potential fixed return of 42%, provided the FTSE 100 Index at the end of the term is higher than its value at the start of the plan (subject to averaging). As with other cash deposits, your capital is also eligible for FSCS* protection.

The 42% return is equivalent to 6.38% compound growth each year, which is well over double the best fixed rate bond, and more than 4% per year higher than the top fixed rate Cash ISA.

The downside is that the return is not guaranteed, and so if the FTSE ends lower, you only get your initial capital back.”

  • 42% fixed return if the Index is higher
  • Capital protected product*
  • Eligible for the Financial Services Compensation Scheme (FSCS)
  • Returns not guaranteed. You may only receive a return of your original capital
  • Minimum deposit £3,000
  • Plan designed to be held for full term

What are ISAs

ISAs, also known as individual savings accounts, can give you the opportunity to earn up to £20,000 tax-free interest on your savings.

The benefits of an ISA are not restricted to tax-free interest on your savings, you can also enjoy tax-free returns from any investments your make through your ISA.

Fixed rate ISAs

Cash and instant access ISAs are very popular, as you can access tax-free interest and make a withdrawal of any size at your convenience. However, a common complaint about cash ISAs is that they rarely offer you competitive interest, which could make the tax-free interest not as appealing.

A fixed rate ISA is an ISA that offers you the chance to get a higher rate of interest than cash or instant access ISAs. In order to access this higher rate of interest, fixed rate ISAs require you to leave your savings untouched in the ISA for the full duration of the fixed term. The longer you are prepared to leave your savings, the higher the interest you will receive.

When looking at your ISA options you may want to weigh up what is more important to you: unlimited access to your savings or higher interest rates?

If you are confident that you will not require access to your savings in the near future, then a fixed rate ISA could be an attractive option for you.

Fixed rate ISA calculator

When deciding on which fixed rate ISA to choose, you should always review the following:

  • The minimum ISA deposit
  • Additional bonus rates available
  • How the interest is calculated
  • Early closure penalties

If you want to open a fixed rate ISA account, then you should find out which ISA suits your financial needs. Our fixed rate ISA table above shows some of the best fixed rate ISA deals on the market.

How much can I pay into an ISA?

21st March 2019

Each tax year, there's a limit set by the government to the amount you can save and invest in ISAs: your “annual ISA allowance”. The allowances are intended to reward savers and encourage us to invest more to support our future retirements, without creating a tax haven that can be taken advantage of by very wealthy individuals who just want to avoid paying tax.
