1. What is the interest rate?


Balance grows by less than £50 a month:
regular saving condition
is not met

Balance grows by at least £50 a month:
regular saving condition is met


AER/Gross p.a. (variable)

AER/Gross p.a. (variable)

£1 – £10,000



Over £10,000




Interest is paid on the above tiers on a stepped basis which means you’ll earn a different rate on each portion of your balance within the above tiers. If, for example, you hold £11,000 in your account, and you have satisfied the regular saving condition, your interest rates for that monthly period will be: 1.50% on the first £10,000 and 0.20% on anything over £10,000.

You can find details of the regular saving condition in the Additional information section. Interest is calculated daily and paid on the first business day of the month and at account closure. You’ll be able to see and access the interest in your account on the following day.

2. Can NatWest change the interest rate?

Yes, these rates are variable. They may be changed for any of the reasons set out in General Term 9.2 of the Savings Account Terms (PDF, 605k), e.g. to take account of Bank of England base rate changes. If the rates are going down we’ll give you at least 60 days’ notice. If they are going up, we’ll inform you before the change or shortly afterwards. Term 9.2 contains details of the notice we’ll give you.

3. What would the estimated balance be after 12 months based on a range of deposits?



Initial deposit at account opening

Balance after 12 months (includes £600 deposited over the 12 months)

Interest earned

£50 deposited every month: regular saving condition is met










  Initial deposit at account opening Balance after 12 months (includes £300 deposited over the 12 months)


Interest earned

£25 deposited every month: regular saving condition is not met













These are only examples and do not take into account your individual circumstances. They assume that no further deposits or withdrawals are made; there is no change to interest rates and tiers; and any interest earned stays in the account.

4. How do I open and manage my account?

  • You must be a UK resident aged 16 years or over and already have a current account with us, or apply for a current account with us at the same time.
  • We will also need your email address and mobile number to open your account.
  • You can only have one Savings Builder Account in your sole name, and only one Savings Builder Account in joint names with another person
  • You can open and manage your account in the mobile app, online, in branch and by telephone
  • No minimum deposit is required to open the account; and there is no maximum balance limit
  • Each month your balance must grow by at least £50 to earn interest. If your balance grows by less than £50 in any month, you will not earn interest

5. Can I withdraw money?

Yes. No notice is required. You can withdraw money:

• In branch

There are daily limits on the amount you can transfer from your account online, by telephone or on the mobile app. 

Find out the current daily limits and how to withdraw more than them here, or by contacting telephone banking. Please note: Withdrawal during the month which means your month to month balance does not increase by £50 or more will result in the regular saving condition not being met and interest not being earned.

6. Additional information

How do I earn interest?

  • To earn interest each month, your balance must grow by at least £50. The monthly cycle to grow your balance and earn interest runs from close of business on the second-last business day of one month, to close of business on the second-last business day of the following month
  • Close of business times differ depending on whether you pay in your money in-branch or by using our telephone, online or mobile app services.

What happens if my payment is late?

  • Your payment will count towards the following monthly cycle. If due to the late payment you have not grown your balance by £50 in that month, you will earn no interest in that month.

What happens if I make a withdrawal?

  • Savings Builder allows you to make withdrawals however if your withdrawal means that your overall balance has not increased by £50 on what it was on the second-last business day of the previous month, you will not earn interest for that month.


What happens if I close my account?

  • You will not earn interest for the month of closure.
