"RPI= Retail Price Index, aka 'inflation'"
Not to be confused with CPI = Consumer Price Index aka 'inflation'. Or WPI = Wholesale Price Index aka 'inflation'. Perhaps its successor PPI = Producer Price Indices?
CPI excludes housing costs and is a geometric mean rather than RPIs arithmetic mean. CPI also tends to be lower than RPI, which is why the government links payments to CPI and receipts to RPI to ensure that increases in what is pays out increases at a lower rate than what it takes in.
