The menu multiplier in restaurants
The multiplier is the shortest road from a cost to a price. It is also the most misunderstood: applied to the net cost, it gives a price including VAT — and that detail moves the figure by 10 %.

The calculation
gross selling price = net food cost × multiplier. That is the custom in French restaurants: net cost, price including VAT. The multiplier therefore includes VAT — a “net to gross” multiplier of 4 is only 3.64 before tax, at the French 10% rate.
Two people who say “a multiplier of 4” are not necessarily talking about the same price. Saying which way it applies avoids menu-price gaps that show up at the first service.
Worked example: €4.50 food cost, multiplier of 4
The multiplier applied to the net cost, with 10% French VAT included in the price.
| Selling price including VAT | €18.00 |
|---|---|
| Net selling price | €16.36 |
| Actual multiplier, net to net | 3.64 |
| Food cost, as a share of the net price | 27.5% |
| Net gross margin per plate | €11.86 |
Applied net, with VAT added afterwards, the same multiplier of 4 would have given €19.80 including VAT instead of €18.00. Neither is wrong — but you need to know which one you are applying.
Which benchmarks
Custom puts traditional restaurants between 3 and 4, bistros and brasseries between 3.5 and 4.5, and drinks higher again. These are benchmarks, not standards: the right multiplier is the one that leaves enough cash margin once the dish sells at its real volume.
What the multiplier does not see
It ignores losses: applied to a cost worked out before trimming, it gives a price that does not cover the dish. It ignores the structure of the menu: prices that are each right for their cost can form an inconsistent range. And on wine, a flat multiplier makes the fine bottles unsellable — the scale there tapers.
