Explanation of Fuel Surcharge Calculation
Verbose description of fuel Levy calculation
Base Net fuel price is $0.69 from when DXT started to apply a fuel levy
Get current price: www.aip.com.au/pricing
That gets a net price of the current fuel
Get the difference in net price
Divide the difference by the Base net price to get percentage change from base.
Divide the percentage change by fuel factor (32%) to get the fuel levy.
BF= 0.69 (Base fuel when DXT started applying fuel levy. This is a net value, ex rebate and GST)
CF = current fuel (Regional average diesel price as published by AIP, NSW/ACT for each week ending of the previous month divided by number of weeks)
CR = diesel fuel current rebate
Mathematical Description of Fuel Levy Calculation
Fuel levy =((((CF/1.1)-CR)-BF)/BF)*0.32
Example for June 2012
Fuel levy =((((1.385/1.1)-0.15043)-0.69)/0.69)*0.32
