The Syntec Index measures changes in the cost of services in the engineering, IT services, research and consulting recruitment, and professional training sectors.

Its value reflects the evolution of salary costs (including charges). The Syntec Index is used in particular to index contracts for fixed-price projects, IT management, or software maintenance.

The Syntec Index (base 100 1961) is calculated and published by the Syntec Federation (not INSEE) or by paying services such as “Le Moniteur“.

How to use the SYNTEC index?

Rule:

The prices of the service contract may be revised at each contract expiration date according to a formula that integrates the evolution of the Syntec index. The reference index used will be that of November (example).

The formula for applying the Syntec 2021 Index:

[New Price (P1)] = [Old Price (P0)] * [Known Reference Syntec Index (S1)] / [Reference Syntec Index (S0)] :

To help you, you can use our table in Excel: Price increase 2021 – Syntec index.

Tip:

For price revisions on the first of January of each year, it is advisable for practical reasons to take the November or October Syntec index as a baseline. Indeed, the December index is only known at the end of the following January, which is late for the application of contractual price increases.

The values in this table will be updated as the index is published during the year 2021.
