Capacity Utilisation & Production Efficiency

Measure how effectively available production capacity is being used. Calculate capacity utilisation, production efficiency, output shortfall, idle capacity and the estimated cost of unused operating time.

1. Production Capacity


Total hours available during the selected period.


Hours actually spent operating the production process.

2. Production Output


Expected output per operating hour under standard conditions.


Actual good units produced during the period.


Output target for the same period.


Optional cost assumption for estimating idle-capacity cost. Enter 0 if unknown.

Capacity and Efficiency Results

Capacity Utilisation
—
Operating hours ÷ available hours.

Production Efficiency
—
Actual output ÷ standard output for actual operating hours.

Production Plan Attainment
—
Actual output ÷ planned output.

Idle Production Hours
—
Available hours minus actual operating hours.

Theoretical Capacity Output
—
Output possible at the standard rate for all available hours.

Standard Output for Actual Hours
—
Expected output at the standard rate for actual operating hours.

Output vs. Production Plan
—
Shows the shortfall or excess against planned output.

Estimated Cost of Idle Capacity
—
Idle hours multiplied by the cost per available hour.

Production Analysis

Formulas:
Capacity utilisation = actual operating hours ÷ available production hours × 100.
Production efficiency = actual output ÷ (actual operating hours × standard output per hour) × 100.
Plan attainment = actual output ÷ planned output × 100.
Idle hours = available hours − operating hours.
Estimated idle-capacity cost = idle hours × cost per available hour.

Capacity utilisation measures how much available time was used. Production efficiency measures how much output was achieved during the time actually operated. Plan attainment compares actual production with the target. These measures are different and should not be interpreted interchangeably.

Example Reference

The figures below are illustrative only. They are not entered automatically into the calculator.

Available Production Hours
2,000

Actual Operating Hours
1,600

Standard Output per Hour
50 units

Actual Production Output
70,000 units

Example results:
Capacity utilisation = 1,600 ÷ 2,000 × 100 = 80%.
Standard output for actual operating hours = 1,600 × 50 = 80,000 units.
Production efficiency = 70,000 ÷ 80,000 × 100 = 87.5%.
Idle capacity = 2,000 − 1,600 = 400 hours.
If the cost per available hour is ₹1,500, estimated idle-capacity cost = 400 × ₹1,500 = ₹6,00,000.

Assumptions: Available and operating hours refer to the same production resources and period. The standard production rate is assumed to be comparable with actual output. The idle-capacity cost is an estimate, not necessarily an avoidable cash cost or a measure of lost profit.
