Is the Machine Worth It? Four Numbers to Work Out

Labour, changeover and downtime, rework and material loss, and effective output. No preset payback promise: the estimate uses your real production data.

Labour

Headcount × hours per person × hourly labour cost. Compare the spend that can be reduced over the same period.

Changeover & downtime

Setup time + waiting time + hand-over time between processes. Count the effective hours lost to changeovers and waiting.

Rework & material loss

Rework + scrap + other non-conformance losses, converted to money, without counting the same loss twice.

Effective output

Good parts per hour × effective production hours. Assess added output separately to avoid double counting.

Estimated payback (months) = total project investment ÷ net monthly saving, after deducting added running and maintenance costs. The estimate depends on actual production data and is not a guaranteed payback.
