Indian kitchens lose 4-7% of food cost to shrinkage; the gap between theoretical food cost (recipe × covers) and actual (purchases ÷ sales). For a 1,400 sqft casual dining doing ₹22L monthly revenue at 31% food cost, that's ₹30,000-₹50,000 a month walking out the door without explanation. Here's where it goes and the audit framework that finds it.
The shrinkage breakdown
| Cause | Typical share | Operational fix |
|---|---|---|
| Over portioning | 40-55% | Portion SOPs + digital scales + visual guides |
| Waste (spoilage + prep) | 20-30% | FIFO + smaller batches + waste log |
| Mismeasurement (cooking yield, weighing errors) | 15-25% | Standardised scales + yield audits |
| Theft (staff, vendor short counts) | 5-15% | Receiving SOP + weekly counts |
The 30 day cycle count
Once a month, take a physical inventory of major SKUs. Don't try to count everything; top 30 SKUs covers 85-90% of food cost.
- Day 1, before service; count opening inventory. Weigh proteins, count vegetables in kg, dairy in litres. Record at current supplier rate.
- Days 1-30; record every purchase via invoice (POS supplier module or spreadsheet).
- Day 30, after service; count closing inventory.
- Compute; Used = Opening + Purchases − Closing. Cost = Used × rate. Theoretical = Recipe × covers.
- Delta; Used cost − Theoretical cost = shrinkage.
Over portioning; the single biggest cause
Without explicit portion SOPs, chefs portion by instinct. Two well meaning line cooks will portion the same dish 15-25% differently. Across a 60 cover dinner, that's 3-5 extra portions worth of food cost out the door.
Portion SOPs that work
- Ladle standards; gravy 80ml ladle, dal 120ml, rice 1.2L scoop. Buy specific ladles; don't let chefs use ‘whatever’.
- Visual guides at the pass; printed plate photos showing acceptable portion sizing. Updated quarterly.
- Spot weights; random plates weighed during peak service. Variance >12% triggers a coaching conversation.
- Pre portioning where possible; proteins weighed and packed pre service. Removes plating time guesswork.
Waste; measurable + reducible
Indian kitchens waste 3-6% of received food in spoilage + prep trim. Mostly preventable:
- FIFO rotation; first in, first out. Date labels on every container. Most spoilage is because old stock gets buried behind new.
- Smaller batch sizes; making 15kg of marinated chicken when you'll use 8kg means 30-40% waste by day 3.
- Waste log; kitchen logs every disposal. Surfaces patterns ("we throw 2kg of paneer every Sunday; why?").
- Trim utilisation; vegetable trims into stock; protein trims into staff meals or specials. Saves ₹15-40k/month for a casual dining.
Mismeasurement; the silent leak
Three sources:
- Yield drift; recipes assume specific cooked yields (1:2.5 rice, 0.65 mutton on the bone). Actual kitchen yield drifts as suppliers change.
- Scale calibration; cheap kitchen scales drift 3-7% over 18 months. Calibrate quarterly with a known weight (1kg packet of sugar).
- Inconsistent receiving; "5 boxes" without checking weight inside. Each box of mango can be 2.4kg or 3.1kg. Insist on weight, not count.
Theft; small but real
Staff theft is 5-15% of total shrinkage in Indian kitchens; smaller than most owners think but real. Closing the door without confrontation:
- Receiving SOP; every delivery weighed/counted in front of the supplier. Signed bill. CCTV at the receiving door.
- Weekly random counts; high value SKUs (paneer, mutton, premium oils, dry fruits). Variance triggers investigation.
- Staff meal SOP; defined staff meal allowance per shift. Eliminates ambiguity ("is it OK if I take this home?").
- Bin audit; what's being thrown away? Some "waste" is actually being taken home.
The single most effective shrinkage intervention is the monthly cycle count itself. Once the kitchen knows you're counting and comparing, behaviour tightens before you change a single SOP. Run your first count without announcing it; then announce monthly counts going forward.
Realistic shrinkage targets
| Period | Acceptable shrinkage | Comment |
|---|---|---|
| Month 1-3 (post opening) | 8-12% | Setup phase; staff learning |
| Month 4-6 | 5-8% | Initial discipline taking hold |
| Month 7-12 | 4-6% | Operating at standard |
| Year 2+ | 3-5% | Mature kitchen; SOPs entrenched |
