Restaurant Shrinkage: What It Is and How to Measure It
Restaurant shrinkage explained: where inventory disappears (receiving, storage, prep, the bar, comps, theft, paperwork), how to measure it as actual minus theoretical usage, a worked example and how to cut it.
What is shrinkage in a restaurant?
Shrinkage is inventory you paid for that disappears without producing a sale: spoilage, waste, over-portioning, receiving errors, unrecorded comps, theft and paperwork mistakes. You measure it as actual usage minus theoretical usage, in dollars, item by item.
Waste you can see in the bin is only part of it. Shrinkage also covers the losses nobody sees: the case that was short on delivery, the extra ounce on every portion, the drink that was poured but never rung in. That is why the reliable way to find it is to compare what your counts say you used with what your sales say you should have used.
Where restaurant shrinkage comes from
| Source | Examples | How you find it |
|---|---|---|
| Receiving | Short deliveries, light case weights, substitutions, damaged goods | Check every delivery against the invoice and weigh proteins |
| Storage | Spoilage, product lost at the back of the shelf, wrong temperatures | FIFO rotation, date labels and temperature logs |
| Prep and portioning | Heavy trimming, oversized portions, recipes not followed | Yield tests, portion scales and standard recipes |
| Bar | Over-pouring, spills, drinks not rung in | Bottle counts against pours sold |
| Comps and voids | Items given away or cancelled after they were made, without a record | Reason codes and a daily comp and void report |
| Theft | Product leaving with staff, free food and drinks for friends | Variance by item, access control, counts of high-value items |
| Paperwork | Counting errors, wrong units, invoices entered twice or not at all | Consistent count sheets and an invoice check |
Useful tools for each step: the receiving log template, the guide to FIFO storage, the butcher’s yield test calculator, the inventory variance calculator for the bar, and the guide to comps vs voids.
How to measure shrinkage
- Count inventory at the start and end of the period, at the same time of day, with the same count sheet.
- Add everything received in between: actual usage = beginning inventory + purchases − ending inventory.
- Work out theoretical usage from sales: items sold × the amount of each ingredient in the recipe.
- Shrinkage = actual usage − theoretical usage. Multiply by the unit cost to get dollars, and divide by theoretical usage for a percentage.
- Subtract the waste you logged to see the part nobody can explain yet.
For the whole kitchen, the same idea works in percentages: actual food cost % minus theoretical food cost % is your variance in points. The food cost variance calculator does both, and the guide to theoretical vs actual food cost explains the method in detail.
Worked example
One month, one kitchen
1Compare actual and theoretical
Food sales are $40,000. Counts and invoices put actual food cost at $13,400 (33.5%); recipes times items sold give $12,000 (30.0%). Shrinkage is $1,400, or 3.5 points.
2Subtract what you can explain
Waste logs account for $480, yield tests below standard for $520 and portion spot checks for $250. That leaves $150 nobody can explain yet.
3Find the item
One item can carry much of it: 140 ribeyes with a 14 oz spec should use 122.5 lb, but the counts show 131 lb used. The 8.5 lb gap is $119 a week at $14 a pound, about $6,200 a year.
