Material Wastage Calculator
Over-consumption, theft and off-market buying against your BOQ — the classic procurement leak.
How to use it — and why it matters
Material is usually the largest cost line on a project and the easiest place for margin to disappear — through over-consumption, wastage, theft and buying above agreed rates. Because purchase records and site consumption usually live in different registers, the leak isn't seen until a year-end reconciliation. This calculator sizes it against your annual material spend.
What counts as material 'wastage'?
Everything that consumes more material than the BOQ allows: genuine wastage and breakage, over-ordering, pilferage, and paying above the agreed rate. 5% is a common working estimate; tight sites are lower.
How do you catch it in real time?
By comparing consumed quantity against the BOQ, per line item, as work is booked — so a line crossing its budget flags the same day instead of at audit.
