# On inflation calculator

If it is needed to calculate changes of consumer prices (inflation) at the time period you have chosen, use Inflation calculator.

Example for consumer price index use in indexation

Aim of indexation is to compensate unfavourable impact on the value of money. Mostly overall consumer price index, which is available in inflation calculator, is used for this purpose.

For example, on 1 January 2012 (in reference period) the value is 711 EUR. To determine the new indexed value at the end of 2012 CPI on period from December 2011 to December 2012 must be used.

From database table „CONSUMER PRICE INDICES BY GROUPS AND SUBGROUPS (2010=100)” price indices needed are obtained:

1) in December 2011 (the reference period) CPI – 105.1

2) in December 2012 (the comparision period) CPI – 106.8

Using this data new value is calculated:

EUR 711 x 106.8/105.1 = EUR 711 x 1.016 = EUR 722.38

New value is larger by 1.6% than the initial (reference period) value. The increase equals inflation in 2012.

CPI calculation period is one month; therefore, CSB cannot provide data on the certain day or week.

For compensation aims price indices of separate consumer groups or producer price indices of some sector or sector groups can also be used.

Other examples

Indexation of food products

From table „CONSUMER PRICE INDICES BY COMMODITY GROUPS” from database section Consumer prices - monthly data choose group „Food products (01.1)”, price changes "(2010=100)" and corresponding period (first – December 2011, then – December 2012) and you will obtain price indices needed:

1) in December 2011 (the reference period) CPI – 107.6

2) in December 2012 (the comparision period) CPI – 111.4

Using this data new value is calculated:

EUR 711 x 111.4/107.6 = EUR 711 x 1.035 = EUR 724.50

New value is larger by 3.5% than the initial (reference period) value. The increase equals inflation of corresponding goods and services in 2012.

Indexing of services

From table "CONSUMER PRICE INDICES BY COMMODITY GROUPS" from database section Consumer prices - monthly data choose group "Services", price changes "(2010=100)" and corresponding period (first – December 2011, then – December 2012) and you will obtain price indices needed:

1) in December 2011 (the reference period) CPI – 101.0

2) in December 2012 (the comparision period) CPI – 101.5

Using this data new value is calculated:

EUR 711 x 101.0/101.5 = EUR 711 x 0.995 = EUR 707.45

New value is less by 0.5% (100%-99.5%) than the initial (reference period) value. The decrease equals deflation of corresponding goods and services group in 2012.

Due to specificity of electronic processing technology of data on account of rounding off the numbers slight discrepancies are possible between data published and calculations carried out by information users.
