OEE & Manufacturing Calculators

Calculate Overall Equipment Effectiveness, understand Availability, Performance and Quality losses, and turn the numbers into an improvement plan. Built by practitioners, not algorithms.

Calculators

All manufacturing calculators

These tools were built with direct input from people who have run UK food and FMCG manufacturing operations at senior level. The benchmarks, worked examples and loss categories reflect how OEE is actually used on the shop floor.

Common Questions

Questions answered

For food and FMCG, a good OEE score depends on your operating model. A high-speed single-SKU line should target 80–85%. A multi-SKU line with frequent allergen changeovers may be performing well at 60–68%. The most useful benchmark is your own trend over time — consistent improvement of 2–5% per year matters more than hitting an industry number.
OEE = Availability × Performance × Quality. Availability measures time losses (line stopped when it should be running). Performance measures speed losses (line running below rated speed). Quality measures defect losses (units that fail to meet specification first time). Each is expressed as a decimal, then multiplied together.
85% is the widely cited world-class benchmark. At 85% OEE you are making good product, at full speed, with no unplanned stops for 85% of your planned production time. Most manufacturing sites average 60–65%.
The most common causes are changeover time and CIP (Availability), unplanned breakdowns (Availability), minor stops and jams that operators restart without recording (Performance), running below rated speed due to product variability (Performance), start-up scrap during line stabilisation (Quality), and rework from fill weight or seal failures (Quality).
