NS&I Investment Account
What is the interest rate?
We calculate the interest daily and add it to your account once a year on 1 January.
Can NS&I change the interest rate?
Yes - the rate is variable so we can change it up or down from time to time, for example when the Bank of England base rate
changes or when rates in the general savings market change. See the customer agreement (terms and conditions) for more details.
We’ll give advance notice of any rate changes by publishing adverts in a range of newspapers and by updating our website.
When the rate is going down, we’ll also contact you personally in advance to let you know.
What would the estimated balance be after 12 months based on a £1,000 deposit?
A £1,000 deposit would be worth £1,008.00 after 12 months, if the current interest rate stayed the same during the 12 months.
This is an illustration only, so it doesn’t take into account your individual circumstances. It assumes that you don’t make
