SMV / SAM Calculator
Calculate garment standard minutes, production capacity, and estimated labor cost using your operation time study.
01. Production Settings
100% represents normal performance.
For personal needs, fatigue and unavoidable delays.
Total scheduled shift duration.
Expected production efficiency.
Operators assigned to production.
Enter your local hourly labor cost.
02. Garment Operation Breakdown
Enter the observed time for each operation in seconds. You can add as many operations as needed.
| Operation | Observed Time (sec) | Rating (%) | Normal Time (min) | Allowed Time (min) | Action |

Included in this calculation
Formula: Normal Time = Observed Time × Performance Rating ÷ 100.
SAM: Normal Time × (1 + Allowance ÷ 100).
Production Capacity: Available operator minutes × Target Efficiency ÷ SAM.
Labor Cost: SAM ÷ 60 × Hourly Labor Cost.
Important: This calculator applies allowances as a percentage of normal time. Some factories calculate allowances using a different convention. Use your factory’s approved method when preparing official costings.
SAM: Normal Time × (1 + Allowance ÷ 100).
