How to Cut Restaurant Waste and Stop Losing Money to Shrinkage

Waste and shrinkage are the quietest way a restaurant loses money. There's no single dramatic moment — just a little spoilage here, a heavy hand there, a few "missing" kilos each week. Added up, it can equal your entire profit margin.

Know the three kinds of loss

• Waste — food that spoiled, was over-prepped, dropped, or cooked wrong. Visible, and largely preventable.
• Over-portioning — real product going into dishes, just more than the recipe says. It hides inside your food cost.
• Shrinkage — stock that vanished beyond sales and logged waste. This is the theft-and-leak signal, and it's the one owners rarely measure.

You can't fix what you don't separate. Treat these as three different problems.

Log every bit of waste

Put a simple waste log by the bin. Every time something is thrown out, record what, how much, and why. It feels tedious for a week — then it becomes the most valuable page in your kitchen. Patterns appear: the salad prepped too early, the special that never sells, the supplier delivering short-life produce.

Standardise portions

Over-portioning is the most common invisible leak. Scoops, ladles, portion scales, and clear recipe photos remove the guesswork. Train once, check occasionally, and your food cost tightens without a single price change.

Run a variance report

This is the powerful one. Compare theoretical usage — what your recipes say you should have used based on what actually sold — against real usage from your stock counts. The gap is your variance:

• Small and steady? Normal.
• Large or growing on a specific item? That's your leak — investigate it.

Variance turns "I feel like we're losing stock" into "we lost 6kg of chicken beyond what we sold last week." That's a number you can act on.

Fix ordering and par levels

A lot of "waste" is really over-ordering. If you bin the same item every week, your par level or order quantity is wrong. Tighten it. Order more often in smaller amounts for short-life produce.

Rotate religiously

FIFO — first in, first out — with clear date labels is your cheapest, most effective anti-spoilage tool. Older stock always sits in front.

Make it a weekly rhythm

• Count key high-value items weekly
• Review the waste log
• Run the variance report
• Act on the biggest gap, then repeat

Consistency beats intensity. A modest weekly check will recover far more than a heroic monthly deep-dive you skip half the time.

DineCore tracks waste, calculates variance and shrinkage automatically, and shows theoretical vs actual usage per item — so the money leaking out of your kitchen stops being a mystery and starts being a number you can close.
