Enter five figures you already have. This shows what your kitchen actually consumed, what your sales say it should have consumed, and the gap between the two — with every step of the arithmetic visible.
No hidden model — three lines of arithmetic you can check by hand:
| Actual consumption | opening stock + purchases − closing stock |
|---|---|
| Actual food cost % | actual consumption ÷ food sales × 100 |
| Expected cost | food sales × your target food cost % |
| Unexplained gap | actual consumption − expected cost − recorded wastage |
The annual figure is simply the same gap repeated twelve times if nothing changes. It is an illustration of scale, not a forecast and not a promise of savings.
The gap is the portion of your consumption that sales, recipes and recorded wastage do not account for. Several very different things land in the same number:
It tells you how much to investigate. It does not tell you which of these it was — and any tool that claims otherwise is guessing. A high gap on its first run most often turns out to be records rather than crime: an item recorded under two spellings, a rate typed wrong, or a purchase everyone remembers that nobody wrote down.
RestroMatrix runs this arithmetic continuously — purchases, stock counts, wastage and cash recorded by your team as they work, with the gap attributed to a day and a shift. It works alongside your existing POS.
