What is unplanned downtime really costing your plant?

Enter your numbers below. The cost updates instantly — no signup, no spreadsheet. Most plants are surprised by the yearly number.

Your plant — your numbers

Count the machines or lines where unplanned stops hurt output.

machines

Breakdowns, waiting, changeover overruns, no material, no operator — only unplanned time.

hrs / week

Lost sales value or burdened machine-hour rate — whichever your plant uses to value an hour.

$ / hour

50 is typical after holidays and planned shutdowns.

How this is figured: 5 machines × 4 hrs/week × 50 weeks = 1,000 hrs/year × $250/hr.

Cutting downtime is a system, not a slogan.

You don't fix downtime with a poster. You fix it by finding where the hours go, scoring the plant honestly, and working a plan week by week. That's exactly what the Plant Excellence Audit & Rollout Kit gives you — the same system, ready to run in your plant.

Comparable plant-assessment and TPM consulting engagements run $5,000 and up. This is the same system, in a kit you run yourself — and the software and templates match the compatibility of the big-name packages.

Try it with one problem line first. Put in that line's real downtime and rate — if the number still hurts on a single machine, you have your starting point for the audit.
