Copper and Aluminum Price Calculation

The material price for cables and wires is usually based on a copper price of 150.00 EUR/100 kg. For invoicing, as copper surcharge – the difference to the daily copper rate will be calculated.

Formula for calculating the copper surcharge:

Copper surcharge in EUR/km = Copper value (kg/km) x 

(DEL+1% delivery charge) - copper basis

  100

DEL
The DEL (German electrolytic copper for guiding purpose) is the Stock Exchange Quotation for 99.5% pure copper. The value is given per EUR/100 kg in the economic part of daily newspapers.

Example:
DEL quotation = 194.29
100 kg copper cost 194.29 EUR and
1% delivery charge is added to the daily quotation for cables and wires.

Copper basis
In our catalog, for almost all cables and wires, a certain portion of copper price is already included.
Standard cables - copper basis = EUR 150.0/100 kg
Telephone cables - copper basis = EUR 100.0/100 kg
Power cables - copper basis = EUR 0 /100 kg (copper base = 0)

Copper value
The copper value is stated in our catalog. It is the copper weight of a cable or a wire.

Example:
JZ-500 8 x 0,75 mm², Part-No. 10040
Copper value 58 kg/km

DEL: 194,29 EUR/100 kg (assuming value)
Copper basis: 150.0 EUR/100 kg Copper value 58 kg/km

Copper surcharge = (194.29 + 1.9429) - 150.0 x 58 kg/km = 26.82 EUR/km
  100    
 
(calculated value 1.9429 = 1% of 194.29)

The net price including copper is calculated as follows:
Gross price
/ Individual discount
+ Copper surcharge

Calculation examples:
Assumption: 
•   DEL-Quotation 194.29 EUR/100 kg for copper
•   Daily rate 173.84 EUR/100 kg for aluminium
•   Individual discount, e.g. 20%

1. NYY-J 3 x 70/35 sm - 0.6/1 kV, P/N 32038

Quantity ordered 1000 m

 
Copper base = 0 9300.00 EUR/km
minus 20% (discount)
1860.00 EUR/km
  7440.00 EUR/km
   
+ Copper surcharge:  
   
  (194.29 + 1.9429) - 0 x Copper value
  100  
 
   
equal, 1.962 EUR/kg x 2352 kg/km =    4614.62 EUR/km
  12054.62 EUR/km

2. NYCWY 3 x 70/35 sm - 0.6/1 kV, P/N 32268

+ Copper surcharge:  
   
  (194.29 + 1.9429) - 0 x Copper value
  100  
 
   
equal, 1.962 EUR/kg x 2410 kg/km =    4728.42 EUR/km
  16552.42 EUR/km

2. NA2XSY 1 x 70 sm/16 - 12/20 kV, P/N 32454

+ Copper surcharge:  
   
  (194.29 + 1.9429) - 0 x Copper value
  100  
 
   
equal, 1.962 EUR/kg x 182 kg/km = 357.08 EUR/km
   
+ Aluminum (conductor)  
Aluminum value x daily rate  
203 kg/km x 1.74 EUR/kg    353.22 EUR/kg
