Morphology

charge + per + unit

The meaning 'cost or fee for each individual item' follows directly from combining 'charge' (a fee) + 'per' (for each) + 'unit' (an individual item), so the overall sense is compositional and predictable. This is a standard rate-expression pattern common across languages and in English usage, making it immediately understandable to a B1 learner who knows the constituent words.

Etymology

Charge per unit is like a shop price for one item: the charge is the money you pay and the unit is a single item, for example one apple or one kilowatt hour. So it means the 'cost or fee for each item or measure'.
