Interest is calculated each day on the money in the account and paid:
  • annually (each year), on each anniversary of your bond opening; or
  • monthly, starting one month after the date your bond opened, and then each month after that;
    whichever you choose.
  • Can Principality change the interest rate? No, the rate is fixed for three years until the bond matures (when the account comes to an end).
    What would the estimated balance be after 36 months based on a £1,000 deposit? £1,139.53

    This is based on you choosing to have interest paid annually and added to your bond and you not making any further payments into the account.
