How to Calculate Hourly Production Target

In apparel production, you may often need to calculate hourly production target for a given style for setting up production target and production planning. The hourly production target is calculated for individual operators as well as for a line as needed. 

In this article, I will show you

1. How to calculate hourly production target for an individual operation 
2. How to calculate hourly production target for a production line.

Hourly production target calculation is a part of an operation bulletin preparation and daily production report. In an OB production target is calculated for each operations.

Following formula is used to calculate hourly target.

Hourly production target = (60 / Operation SAM)

An hour is equal to 60 minutes. Divide the 60 by the operation SAM. The end result of this calculation tells you the number of pieces can be produced per hour, which is the hourly production target for the selected operation.

Let’s take an example. SAM of an operation is 0.5 minute. Hourly production target would be

=(60/0.50) =120 pieces

Note: This target is calculated at 100% efficiency. In case you want to plan hourly production target at particular percentage, multiply the above by individual operator efficiency.

Let’s say skill level of that operator is 80% efficiency, in that case production target would be

(60/0.50)*80% =120*80% =96 pieces

The information you need for calculating hourly production target are

1. Standard time (SAM) of the operation
2. Average efficiency of the line

Calculation of Hourly production target of a line

On the other hand for calculating hourly production target for a production line use the following formula

Hourly Production Target of a line =((60 * No. of operators working in a line * Line efficiency %) /Garment SAM)

If you need to calculate daily production target of a line, just multiply the hourly line target by shift hours.
