The figures provided by the calculator are a guide only and are not a precise calculation.
Interest RatesThe calculator assumes the interest rate does not change throughout the calculation. The calculation assumes we will pay your interest without tax taken off. We pay your interest with tax taken off at the lower rate of 20% (net interest). If you do not pay tax and have filled in an HM Revenue & Customs R85 form, we will not take tax off your interest (gross interest).
Length of MonthMonths are of equal length.
Deposit frequenciesThe calculator assumes the same deposit is made every month, at the same time as cleared funds.
Rounding The calculator rounds to the nearest 0.1%, in some cases the calculator may underestimate interest paid.
AER Stands for Annual Equivalent Rate. It shows what the interest rate would be if the interest was reinvested in the account each year.
