Production Loss Calculator

Calculate production loss in litres/kg and as a percentage of planned output. Track lost production value and identify improvement opportunities.

L or kg
Total planned production volume for the period
L or kg
Actual production volume achieved
Price per litre or kg for loss value calculation
Formula
plannedProduction - actualProduction

Worked Example
1
Given:
actualProduction = 91500
plannedProduction = 100000
2
Apply the formula:
plannedProduction - actualProduction

Result:8500 L or kg

Understanding Production Loss

Production loss is the gap between what you planned to produce and what you actually produced. It has a direct financial impact that is often underestimated.

Production Loss (L or kg) = Planned Production − Actual Production

Loss Value (₹) = Production Loss × Price per Unit

Types of Production Loss

1. Availability Losses

  • Unplanned breakdowns
  • Extended CIP time
  • Change-over delays
  • Startup and shutdown losses

2. Performance Losses

  • Speed reduction (running below capacity)
  • Minor stops and idling
  • Raw material flow issues

3. Quality Losses

  • Product rejection and rework
  • Off-spec product downgraded to lower value
  • Adulteration detection rejections

Converting Loss to Financial Impact

Dairy plants typically track:

  • Direct milk loss — cost per litre of raw milk × volume lost
  • Product revenue loss — product selling price × volume not produced
  • Fixed cost inefficiency — utilities, labor costs absorbed by less output

Example: A pasteurizer running at 85% of capacity for 8 hours:

  • Installed capacity: 30,000 L/hour
  • Planned: 30,000 × 8 = 240,000 L
  • Actual: 240,000 × 0.85 = 204,000 L
  • Loss: 36,000 L × ₹42/L = ₹15,12,000 lost revenue potential
