Calculation Results

Calculation Formula

Effective Capacity = Total Capacity × (Operating Hours per Week - Downtime per Week - Maintenance Time per Week)

Where:
Total Capacity: Maximum production output per hour
Operating Hours per Week: Total production hours per week (shifts per day × hours per shift × days per week)
Downtime per Week: Total downtime hours per week (downtime per shift × shifts per day × days per week)
Maintenance Time per Week: Total maintenance hours per week

How to Use This Calculator

  1. Enter your total production capacity in units per hour
  2. Input the average downtime per shift (in hours)
  3. Specify the maintenance time required per week (in hours)
  4. Select the number of shifts your operation runs per day
  5. Choose how many days your operation runs per week
  6. Click the "Calculate" button to compute your effective capacity

Understanding Effective Capacity

Effective capacity is a crucial metric that shows how much of your total production capacity is actually being utilized. It accounts for all the time when your production isn't happening due to downtime, maintenance, holidays, or other interruptions.

The formula used in this calculator is:

Effective Capacity = Total Capacity × (Operating Hours per Week - Downtime per Week - Maintenance Time per Week)

Capacity Utilization

Capacity utilization is the percentage of potential output that is actually realized. It's calculated as:

Capacity Utilization (%) = (Effective Capacity / (Total Capacity × Operating Hours)) × 100%

A higher capacity utilization typically indicates more efficient operations, though the ideal percentage varies by industry.

Example Scenario

Suppose a factory has the following parameters:

  • Total Capacity: 500 units/hour
  • Downtime per shift: 1 hour
  • Maintenance time per week: 8 hours
  • Shifts per day: 2
  • Operating days per week: 5

With these parameters, the calculator would show an effective capacity of approximately 4,400 units per hour, with a capacity utilization of about 88%.
