NS&I Investment Guaranteed Growth Bonds

What is the interest rate?

3-year term, Issue 1
2.20% gross/AER

We calculate the interest daily and add it to your Bond on each anniversary of investment.

Can NS&I change the interest rate?

No, you’ll receive the rate on offer at the time you invest and that rate will be fixed for the 3-year term.

What would the estimated balance be at the end of the term based on a £1,000 deposit?

A £1,000 deposit would be worth £1,067.46 at the end of the 3-year term.

This is an illustration only, so it doesn’t take into account your individual circumstances. It assumes that you don’t make any withdrawals during the term.

How do I open and manage my account?

Our Investment Guaranteed Growth Bonds are for customers aged 16 or over. You can invest in Bonds in your own name or jointly with one other person.

You can:

  • apply for, and manage, your Investment Guaranteed Growth Bonds online only
  • invest at least £100, paid by a debit card in your own name, issued by a UK bank
  • invest up to a total of £3,000 per person

Can I withdraw money?

Yes, before the end of the term you can cash in all or part of your Bond online with no notice. We will deduct a penalty equal to 90 days’ interest on the amount you cash in. This means that if you cash in within 90 days of buying your Bond, you’ll get back less than you invested. You need to keep a balance of at least £100 to keep your Bond open.

At the end of the term you can cash in with no penalty. We’ll contact you about a month before the end of the term to let you know your options.

Additional information

We add your interest without deducting any tax. However, the interest is taxable so it will count towards your Personal Savings Allowance.

We’ll send you a statement in April each year, showing the interest you’ve earned and any withdrawals you might have made. You can choose to receive your statements electronically or by post.


Gross is the taxable rate of interest without the deduction of UK Income Tax.

AER (Annual Equivalent Rate) illustrates what the annual rate of interest would be if the interest was compounded each time it was paid. Where interest is paid annually, the quoted rate and the AER are the same.

  • Cashing in

    You can cash in your Bond at the end of the 3-year term with no penalty.

    You can also cash in before that, but we will deduct a penalty from your payment equivalent to 90 days’ interest on the amount cashed in.

    When you cash in part of a Bond, at least £100 must remain in the Bond to keep it open.
