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 last updated on February 2019
only relevant if you cash in your Certificate in March 2019
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 2010, you should enter the renewal date of 20 July 2015.
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.
