Man to Machine Ratio (MMR) Calculator
Find out how many employees your factory carries for every operational sewing machine. Enter your total manpower and machine count, then press Calculate.
Man to Machine Ratio Formula
Man to machine ratio is the total workforce of a factory divided by the number of operational sewing machines.
MMR = Total Manpower / Total Operational Machines
A lower ratio means fewer indirect and support employees for each machine, which usually points to lower overhead cost.
For a factory running two shifts, count the machines once for each shift they run:
MMR = (Manpower of Shift 1 + Manpower of Shift 2) / (Machines used in Shift 1 + Machines used in Shift 2)
MMR Calculation Examples
| Scope | Manpower | Machines | MMR |
|---|---|---|---|
| Whole factory | 1000 | 500 | 2.00 : 1 |
| Whole factory | 800 | 500 | 1.60 : 1 |
| Whole factory | 1100 | 500 | 2.20 : 1 |
| Sewing floor only | 630 | 500 | 1.26 : 1 |
How to Read Your Result
There is no official standard for MMR. An informal survey of 32 industrial engineers in Bangladesh and other countries gave an average of about 1.71, so treat that figure as a rough reference rather than a fixed target.
Your ideal ratio depends on the product, the factory structure and the departments you include in manpower.
Man machine ratio formula
Man to Machine Ratio (MMR) is determined by the formula:
Machine to Machine Ratio (MMR) = Total Manpower/Total Number of Machines
This formula quantifies the relationship between the workforce and machinery, providing insights into resource allocation and operational efficiency.
