Morphology

cost + overrun

The phrase is directly compositional: 'cost' (monetary amount) combined with 'overrun' (an amount exceeding what was planned) yields 'the amount by which costs exceed the budget.' This compound follows a common English and cross-linguistic pattern, so a B1 learner who knows both constituents can readily infer the meaning.

Etymology

Cost overrun comes from the simple picture of costs 'running over' a limit: imagine a budget line and the costs like water that overrun and spill past it. So it means 'the amount by which actual costs go past the planned budget'.
