This module calculates shipping costs based on weight, applying a base charge for orders up to a minimum weight and an additional rate for any weight exceeding that minimum.
Commerce shipping extra weight formula considers only base charge if order weight is lower or equal to minimum weight. It applies extra weight rate for any excess weight above minimum. Some greek shipping companies use this model of charging (i.e. ACS).
For example lets say we set these:
Base rate 5 euro
Minimum weight 3 kg
Extra weight rate 1 euro
If order is below minimum weight (3 kg) shipping will cost 5 euro
If order is 5 kg shipping will cost 5 euro + (5 kg - 2 kg) x 1 = 7 euro
