Get an estimated valuation
The calculator opposite gives a quick estimated value for your Index-linked Savings Certificates. The estimate is:
for guide purposes only
based on the Retail Prices Index (RPI) figure and Consumer Prices Index (CPI) figure last updated on October 2020
only relevant if you cash in your Certificate in November 2020
only for Certificates within their current term
Do you have a Certificate due to mature this month? If so, this
calculator may not be able to give you a result as its too close to
maturity. Please see the maturity letter we sent you, which gives you a
valuation of your Certificate.
To check the RPI, visit the Office for National Statistics website at
and search for RPI All Items Index or CPI All Items Index.
Using the calculator
Have the following to hand:
Amount - The amount invested at the start of the current term
Investment term - your investment has a term of 2, 3 or 5 years
Day, month and year of investment - The date the current term started
What’s meant by 'current term'?
If your Certificate has been renewed, the current term started on the renewal date. For example, if you originally invested
in a 5-year Certificate 20 July 2018, you should enter the renewal date of 20 July 2023.
You’ll also need to enter the value of your investment on that date. You can find this on your latest investment record.
Cashing in penalty
If you cash in before the end of the term, a penalty
will be deducted from your payment and you won't earn any index-linking on the whole Certificate for the investment year
in which you cash in, even if you only cash in part of it. The penalty and loss of index-linking are not included in the
estimate given by the calculator.
