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
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.
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.
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)
The copper value is stated in our catalog. It is the copper weight of a cable or a wire.
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
(calculated value 1.9429 = 1% of 194.29)
The net price including copper is calculated as follows:
/ Individual discount
• DEL-Quotation 194.29 EUR/100 kg for copper
• Daily rate 173.84 EUR/100 kg for aluminium
• Individual discount, e.g. 20%
