You don’t have to put in £100 every month. If you don't it just means you won’t earn the bonus interest for that month and the lower rate of 0.10% AER/Gross p.a. will apply. If you grow your balance by at least £100 the following month, you’ll get your bonus interest again.

Our Savings Builder rewards you for saving regularly by giving you bonus interest every month you grow your balance by £100 or more.

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 bonus condition, your interest rates for that monthly bonus period will be:

1.50% on the first £5,000

1.00% on the next £5,000.

0.20% on the remaining £1,000


You can find details of the bonus condition in the Additional information section.

Interest is calculated daily and paid on the first business day of the month and at account closure. 

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 11.1 of the NatWest Personal & Private Savings Account Terms, e.g. to take account of Bank of England base rate changes or changes in the rates paid by other banks. 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. General Term 11.2 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 £1,200 deposited over the 12 months and the interest earned)

Interest earned (including bonus)

£100 deposited every month: bonus condition is met each month










  Initial deposit at account opening Balance after 12 months (includes £600 deposited over the 12 months and the interest earned)


Interest earned (no bonus: 0.10% AER/Gross p.a.)

£50 deposited every month: bonus condition is not met in any month












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 aged 16 years or over to open an 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.

6. Additional information

Bonus Condition

How do I earn bonus interest?

  • To earn the bonus in each monthly bonus period, your balance must grow by at least £100.
  • A monthly bonus period 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 depend on whether you pay in your money in-branch or by using our telephone, online or mobile banking services.

What happens if my payment is late?

  • Your payment will count towards the following monthly bonus period.
  • If due to the late payment you have not grown your balance by £100 in that month, you will not receive the bonus that month.

What happens if I close my account?

  • You will not earn bonus interest for the monthly bonus period of closure. The interest rate without bonus will continue to apply up until the day you close your account.
