HC Deb 16 April 1958 vol 586 c18W
32. Mr. Atkins

asked the Postmaster-General how many complaints he has had in the last twelve months of the interest due to depositors in the Post Office Savings Bank being wrongly calculated; and whether he has in mind any alteration in the methods used to calculate interest in order to ensure complete accuracy.

Mr. Marples

There were some 900 cases, representing roughly 1 in every 25,000 accounts. We are constantly trying to improve performance under the present clerical method of calculation. No alternative method which would be economic has yet been found.
