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 last updated on 18 July 2017
only relevant if you cash in your Certificate in August 2017
only for Certificates within their current term
To check the RPI, visit the Office for National Statistics website at
and search for RPI 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 on 20 July 2006, you should enter the renewal date of 20 July 2011.
If your investment is still within the original term, enter the purchase date.
You’ll also need to enter the value of your investment on that date. You can find this on:
Renewals on or after 20 September 2012: your latest investment record
For renewals before 20 September 2012: the most recent maturity letter from us.
Cashing in penalty
For Certificates invested in or renewed on or after 20 September 2012, 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.
