How the calculator works
AreaCalculation
1 · Planning effortPeople in planning × annual working hours × planning share × planning hourly rate. The planning share rises with the operations per planner (30 to 85%).
2 · Machine idle timeMachine hours (shifts × 8 h × 5 days × working weeks) × idle share × 30% planning-related × (machines × machine hourly rate + bottleneck machines × contribution margin per bottleneck hour)
3 · Labor idle timeProduction staff × annual working hours × idle share × 30% planning-related × production hourly rate
4 · Premium payPremium pay per month × 12 × 50% planning-related
5 · Late-delivery costOrders per month × 12 × (1 − OTIF rate) × cost per late order

Assumptions for Machinery & plant engineering: machine €90/h, 3,680 h/year · bottleneck contribution margin €120/h · production €48/h · planning €65/h, 1,720 h/year · 30% of idle time and 50% of premium pay planning-related · €1,200 per late order. All values are examples.
