The fluctuation of diesel fuel prices

Due to the cyclical variation of diesel fuel prices in the recent
months, it has been necessary to introduce transparent calculation
methods than can be used for raising or lowering the cost of transport
in accordance with the fluctuating prices of diesel fuel. The following
table has been created for our clients as a suitable way of calculating
the costs of transport in relation to the fuel market prices.

The calculation has been made in the following way:
The decrease or increase of the price depends on the costs of fuel
(excluding VAT) of the previous month. The varying prices of each month
of the year 2008 and 2009 are shown on the following graph. (click on

The above data have been taken directly from the Ministry of Economic
Developement (Ministero dello Sviluppo Economico) and can be seen in the
website

When the fluctuating price remains between 75.01 and 100.00 cents/litre (the
highlighted orange area in the table) there will be no alteration of
transport costs. Higher or lower prices of the aforementioned figures
will receive either an increase or reduction of 1% for everey 5
cents/litre.

Example:
buying price of diesel fuel   76,3 Euroean cents/€ = 0% of additional charges on the cost of transport
buying price of diesel fuel   72,5 Euroean cents/€ = -1% of additional charges on the cost of transport
buying price of diesel fuel 112,9 Euroean cents/€ = 3% of additional charges on the cost of transport
