What is the interest rate?
Interest is paid on a tiered basis at these fixed rates from the date you open your account until the Maturity Date. This means you'll earn one rate on your entire balance. Interest is calculated daily and paid annually to your ISA on the first business day in April and on the Maturity Payment Date.
These are only examples and do not take into account your individual circumstances, or any interest earned prior to the Start Date.
