The purpose of this paper is to explore the current state of reaseach of calculation the consumer price index (CPI). It shows how the CPI and the Harmonised consumer index of consumer price (HICP) are calculated. It specifically reviews how the price data are collected and the calculation on which the CPI is based. It describes the challenges faced by statistical offices in determining the CPI in an ever-changing world and the innovations that must be mandatorily introduced to ensure an inflation rate close to "True Inflation". The paper highlights the necessity to take online prices into account and to create a unique online price index (OPI) with collecting online prices by web-scraping with infinity number. The OPI can be also a good predictor for the CPI. It identifies services, goods, mortgages and assets that are not or insufficiently taken into account in the calculation of inflation but should be, according to current research. It further examines the challenges in price collection, calculation and weighing scheme faced by central banks, Governing Council, governments and statistical offices and how they are resolved. With the growing digitisation in the country, the share of goods and services purchased by consumers from online retailers is also increasing. Online prices are already taken into account to a small extent in the CPI, but should be given greater attention
