How to Calculate Hourly Production Target

 

Learn how to calculate your hourly production target accurately to boost efficiency and meet daily garment manufacturing goals.

The hourly production target helps production managers, line supervisors, and operators understand how many garments need to be produced per hour to meet daily goals. Calculating it accurately ensures smooth production flow and proper line balancing.

Step 1: Gather Necessary Information

You need the following data:

1. SAM (Standard Allowed Minute) – Time required to complete one unit.

2. Efficiency (%) – Target line efficiency (e.g., 80%, 90%).

3. Number of Operators / Machines – Assigned to the line.

4. Working Hours – Duration of one production shift.

Step 2: Use the Hourly Production Formula

$$\text{Hourly Production Target} = \frac{60 \times \text{No. of Operators}}{\text{SAM} / (\text{Efficiency} / 100)}$$

Where:

• 60 = minutes per hour

• SAM = standard time per garment in minutes

• Efficiency = percentage of target efficiency

Step 3: Example Calculation

Given:

• SAM = 0.60 minutes

• Efficiency = 80%

• Operators = 10

Step 1: Adjust SAM for Efficiency

$$\text{SAM @ Target Efficiency} = \frac{\text{SAM}}{\text{Efficiency}} = \frac{0.60}{0.80} = 0.75 \text{ min/unit}$$

Step 2: Calculate Hourly Production

$$\text{Hourly Production Target} = \frac{60 \times 10}{0.75} = 800 \text{ units/hour}$$

Step 4: Key Points to Remember

• Always adjust SAM according to target efficiency.

• Include only active operators/machines in the calculation.

• Use this target for line balancing, daily production planning, and performance tracking.

Quick Formula Summary

$$\text{Hourly Production Target} = \frac{60 \times \text{No. of Operators}}{\text{SAM @ Target Efficiency}}$$
