Calculation formula for copper surcharge

Copper as a resource is still the preferred conductor material used in different wire and cable constructions. Copper has a very good conductivity of heat and electricity. It also provides good deformability without losing its mechanical resistance.

We process only high-quality electrolyte-copper with a cleanliness level of 99.8%, which is standardized by various norms. Copper, like other resources, is traded on the stock exchange. This leads to daily fluctuations of copper prices. The copper price stated in our offers and order confirmations is based on the copper price issued by Südkupfer including 1% purchase costs. Our prices are usually based on EUR 150.00/100kg.


Below we would like to show you the calculation formula.

Copper-weight, copper-number, Cu.-weight

Copper content of wire or cable in kg / km (as shown on catalogue tables)

copper rate

The copper price (SK-Copper Basis UB) issued by Südkupfer is charged with 1% purchase costs.  


Example calculation:
The copper base that may already be included in the cable price (e.g. EUR 150.00) is deducted from the copper rate. The result is then multiplied by the copper weight of the cable. The result is called copper surcharge and will be added to the price of the cable.

Article: LifYY 5 x 0,50qmm 
Amount: 500 m = price EUR 147.90/100 m (copper base EUR 150.00/100kg)
Cu.-weight: 25.7 kg/km = 2,57 kg/100 m
copper rate: EUR 900.00/100 kg + 1% delivery costs = EUR 909.00/100kg
Copper surcharge: (909.00 – 150.00) = 759.00/100kg = 7.59/kg x 2.57 = EUR 19.51/100 m

Total price of the cable: Cable price EUR 147.90/100m
  Copper surcharge EUR 19.51/100m
Total price   EUR 167.41/100m
