Morphology
The meaning is directly compositional: 'per' indicates a rate and 'annum' denotes a year, so together they mean 'for each year' (annually). This is a transparent, cross-linguistically common rate construction (equivalent to 'per year'), so a B1 learner who knows both constituents should infer the MWE's meaning.
Etymology
Per annum comes from old Latin words: per meaning 'for each' and annum meaning 'year'. It was used in writing to show money or events 'each year', so today it means 'for each year'.
