Manufacturing
Production Rate Calculator
Units per hour, shift and day from output and run time, and the time needed for a target quantity.
Rate = units ÷ run time
Also called units per hour · output rate

Manufacturing Calculators
Production rate, cycle and takt time, efficiency, yield, scrap and defect rates, utilisation and unit cost.
Manufacturing
Cycle Time Calculator
Cycle time per unit from production time and output, with the implied hourly rate.
Cycle time = production time ÷ units prod…
Also called cycle time formula · time per unit
Manufacturing
Takt Time Calculator
Takt time — the pace of production needed to meet customer demand — compared with your actual cycle time.
Takt = available time ÷ customer demand
Also called takt time formula · customer demand rate
Manufacturing
Manufacturing Efficiency Calculator
Production efficiency: actual output as a percentage of standard or planned output.
Efficiency = Actual output ÷ Standard / p…
Also called production efficiency · labour efficiency
Manufacturing
Production Yield Calculator
First-pass yield: good units as a percentage of units started, with the defect rate.
Yield = Good units ÷ Units started × 100
Also called first pass yield · fpy calculator
Manufacturing
Scrap Rate Calculator
Scrap (reject) rate: scrapped units as a percentage of total units produced, and the cost of scrap.
Scrap rate = Scrapped units ÷ Total units…
Also called reject rate · waste rate
Manufacturing
Defect Rate Calculator (DPMO)
Defect rate, defects per million opportunities (DPMO) and the approximate Six Sigma level.
DPMO = defects ÷ (units × opportunities) …
Also called dpmo calculator · six sigma level

Capacity utilization = Actual output ÷ Ma…
Also called capacity utilisation · plant utilization
Manufacturing
Production Cost Calculator
Cost per unit from materials, labour, machine time and overhead, including scrap losses.
Unit cost = (material + labour + machine …
Also called manufacturing cost · cost per unit produced
Key manufacturing formulas
| Production Rate | Rate = units ÷ run time |
|---|---|
| Cycle Time | Cycle time = production time ÷ units produced |
| Takt Time | Takt = available time ÷ customer demand |
| Manufacturing Efficiency | Efficiency = Actual output ÷ Standard / planned output × 100 |
| Production Yield | Yield = Good units ÷ Units started × 100 |
| Scrap Rate | Scrap rate = Scrapped units ÷ Total units produced × 100 |
| Defect Rate Calculator (DPMO) | DPMO = defects ÷ (units × opportunities) × 1,000,000 |
| Machine Utilization | Utilization = Run time (hours) ÷ Available time (hours) × 100 |
| Capacity Utilization | Capacity utilization = Actual output ÷ Maximum capacity × 100 |
| Production Cost | Unit cost = (material + labour + machine + overhead) ÷ (1 − scrap rate) |
