Soluzione pragmatica, all’inglese: il calcolo fatevelo da soli! Il National Statistics ha pubblicato il Personal Inflation Calculator.
The Personal Inflation Calculator is a web-based tool that allows users to calculate an inflation rate based on their personal expenditure patterns, rather than the averages used in published statistics. It does this by weighting together price indices from the RPI to arrive at a personal inflation rate.
The personal calculator is designed to allow users to understand more about inflation and how it affects them, and also to contribute to the debate about inflation measurement.
Sarebbe divertente poter giocare con un oggetto simile in Italia.
