Production Loss Calculator — Lost Volume & Value
Free online production loss calculator for dairy plants. Calculate production shortfall in litres/kg and monetary value from planned vs actual production.
Formula
plannedProduction - actualProduction
plannedProduction
Planned Production (L or kg)
actualProduction
Actual Production (L or kg)
pricePerUnit
Value per Unit (optional) (₹)
Worked Example
1
Given:
actualProduction = 91500
plannedProduction = 100000
2
Apply the formula:
plannedProduction - actualProduction
3
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
