📊 Production Planning Breakdown

Parameter Value Unit

How the formula works

Total Hours = (Qty × Cycle Time + Setup) ÷ (Resources × Efficiency)  |  Days = Total Hours ÷ Hours per Day
  • Required Quantity = Number of units to produce
  • Cycle Time = Time to produce one unit
  • Setup Time = Time for changeover/setup
  • Resources = Number of workers or machines
  • Efficiency = Actual output % of theoretical
  • Total Hours = ((Qty × Cycle Time) + Setup) ÷ (Resources × Efficiency ÷ 100)
  • Days Required = Total Hours ÷ Hours per Day
  • Production Rate = Qty ÷ Total Hours (units/hour)
  • Scrap/Waste = Additional units needed to account for defects
