What is gross profit on a dish, and why it matters

What is gross profit on a dish? It is the selling price of the dish, after VAT or sales tax, minus the cost of the ingredients on the plate. A dish that sells for 20 after tax and costs 6 to make earns a gross profit of 14 every time it is sold. That 14 is what the dish contributes towards the wages, the rent, the energy and, eventually, the profit of the business.

It is one of the simplest numbers in a restaurant, and one of the most useful. Yet many venues judge their dishes by a different number: the food cost percentage, the cost as a share of the price. Percentages are easy to compare and feel scientific, but they hide the money. A dish with a low food cost percentage can earn far less per sale than one with a high percentage. The bills are paid in money, not in percentages.

This guide explains what gross profit on a dish is, how to calculate it, how it differs from the food cost percentage and gross margin, why the money beats the percentage for most decisions, and how it feeds menu pricing. It covers the costs gross profit leaves out, such as labour and kitchen time, and how to keep the numbers current.

Gross profit on a dish is its net selling price minus its plate cost. The net selling price is what the venue receives for the dish after VAT or sales tax is taken out. The plate cost is the cost of every ingredient in one portion, including the garnish, the sauce and the oil it is cooked in.

In accounting more broadly, gross profit is sales minus the cost of the goods sold. For a single dish, it is the same idea at the level of one plate.

Three related numbers are often confused:

Gross margin and food cost percentage always add up to 100 per cent. A dish with a food cost of 30 per cent has a gross margin of 70 per cent. Neither tells you how much money the dish earns per sale; only the gross profit does.

Always start from the price after tax. In many countries, menu prices include VAT or sales tax, which belongs to the tax authority, not the venue. A dish priced at 21 with VAT at 5 per cent has a net price of 20. If VAT is 20 per cent, a dish at 24 has a net price of 20.

Calculating gross profit on the menu price, including tax, overstates what every dish earns.

The plate cost is the cost of the ingredients in one portion, worked out from the recipe and current supplier prices, adjusted for yield. A fish that loses part of its weight in filleting costs more per usable gram than its price per kilogram suggests. Every component counts: the bread on the side, the butter, the salt, the oil.

Our guide to recipe costing covers how to build a plate cost from the box price.

Here are two illustrative mains. The figures are examples.

Judged by food cost percentage, the pasta looks far better. Judged by gross profit, the steak earns 6.40 more every time it is sold. If the two sell equally well, the steak contributes half as much again to the business.

The money beats the percentage because the venue's costs are paid in money. The rent, the wages and the energy bill do not care what percentage each dish ran at. They are covered by the total gross profit from all the dishes sold. A menu of low-percentage, low-price dishes can earn less in total than a menu of higher-percentage, higher-price dishes.

That is why many experienced operators say: you bank money, not percentages.

The food cost percentage still has its uses. It is a quick way to spot a dish whose cost is out of line with similar dishes, to check a new dish against the menu's usual range, and to track the kitchen's overall cost over time. A sudden rise in a dish's percentage often means a supplier price has gone up.

Use the percentage as a warning light and the gross profit for decisions. Our guide to what is food cost explains the different percentages.

Menu pricing is where gross profit per dish matters most. When setting the price of a dish, start from the gross profit it needs to earn, not only from a target percentage. A dish that takes little time and sells alongside drinks may need less; a dish that takes a cook ten minutes at the peak may need more.

Our guide to menu pricing: six methods and when each works covers the methods.

One simple method is to decide the gross profit each dish in a section should earn, add the plate cost, and add tax to reach the menu price. If mains should earn at least 15 each and a dish costs 5, its net price should be at least 20, and its menu price that plus tax.

Then check the price against the market and the rest of the menu. A price that earns the target but looks out of place will not sell.

Gross profit can rise without a price change, by lowering the plate cost: a cheaper but equally good garnish, a slightly smaller portion of the most expensive ingredient, a better price from a supplier, or less waste in preparation. Each change raises the money earned on every sale.

Make the changes carefully, so the dish stays as good. Guests notice a smaller steak faster than they notice a different garnish.

Gross profit tells you what a dish earns per sale; popularity tells you how often it sells. Together, they tell you what the dish contributes in total. A dish with a high gross profit that rarely sells may contribute less than a modest dish that sells constantly.

That is the idea behind menu engineering, which sorts dishes by both. Our guide to what is menu engineering explains it in plain language.

Multiply each dish's gross profit by the number sold in a period, and you have its total contribution. Rank the dishes by total contribution, and the menu's real earners become clear. Often, a few dishes earn most of the money.

Protect those dishes. Small improvements to their gross profit, or their sales, move the venue's results more than big changes to dishes that rarely sell.

Across a whole menu, the average gross profit per dish, weighted by sales, is a useful figure to track. If it rises while sales hold, the menu is earning more. If it falls, find out whether costs rose, prices were discounted, or guests moved to cheaper dishes.

Read it alongside average spend per head and covers. Our guide to average spend per head, split properly shows how they connect.

Another useful view is gross profit per cover: the total gross profit for a service divided by the number of guests. It shows what each guest leaves, after ingredients, to pay for everything else. A service where gross profit per cover is rising is earning more from the same guests, through better prices, better selling or lower costs.

Compare it by service. Lunch and dinner, weekdays and weekends, will each have their own level.

Different services can earn very different gross profit. A set lunch at a modest price, a brunch package or an early evening offer may run lower gross profit per dish than the dinner menu, by design, in return for filling seats. That is fine, as long as the choice is deliberate and the service still covers its own labour.

Work out the gross profit for each service from its own sales, so a lower-earning service is a decision rather than a surprise.

Children's menus and small plates often carry lower gross profit per dish, because their prices are low. That does not make them bad. A children's menu brings families who order full meals for the adults; small plates often lead to more plates per table and more drinks.

Judge them by what the whole table earns, not only by the gross profit of each small dish.

The gross profit of a dish can change with the seasons. Ingredients that are cheap and excellent in season can be expensive and poorer out of it. A dish that earns well in summer may earn far less in winter at the same price.

Review the gross profit of seasonal dishes as their main ingredients change in price, and change the dish or the menu rather than letting the margin quietly fall.

Drinks have gross profit too, and it is often high: a glass of wine, a cocktail or a coffee usually earns more per sale relative to its cost than most food. That is why drinks matter so much to a venue's results. Work out the gross profit of the main drinks as carefully as the dishes.

A drink with a modest percentage but a high price may earn more per sale than a cheaper drink with a lower percentage.

Sides, sauces and extras often earn a healthy gross profit for very little cost. A side of fries or a sauce may cost very little to make and sell for several times that. They also raise the total gross profit of a table without needing another cover.

Price them deliberately, and make sure the team suggests them. Our guide to increasing average spend without raising prices covers the moves guests welcome.

Set menus need their own calculation: the net price per guest minus the total plate cost of every course included. A set menu priced to look generous can have a lower gross profit per guest than the à la carte menu, especially if it includes expensive courses.

Check the gross profit per guest of every set menu before offering it, and compare it with what an à la carte guest typically earns.

Discounts come straight out of gross profit. A 20 per cent discount on a dish with a net price of 20 and a plate cost of 6 cuts the gross profit from 14 to 10, a fall of more than a quarter. Promotions that look small on the price can take a large share of what each dish earns.

Do the sum before any promotion. Our guide to offer margin shows how.

Comps and waste reduce gross profit across the menu, because food is used without being sold. A dish that is often sent back or remade earns less than its plate cost suggests. Track comps and remakes by dish, and look at the dishes that cause them.

Gross profit on a dish leaves out every cost except the ingredients: the labour to prepare and serve it, the energy to cook it, the rent of the space, the card fees on the payment. That is not a flaw; it is the point. Gross profit is what is left to pay for all of those.

But it means a dish with a high gross profit can still be a poor dish for the venue, if it takes a great deal of labour.

Some dishes take far more kitchen time than others. A dish that earns a high gross profit but takes a cook fifteen minutes at the peak may slow service and cost more in labour than its gross profit suggests. A dish that earns a little less but takes two minutes may be more valuable on a busy night.

Consider kitchen time alongside gross profit, especially for the dishes that sell most at the peak.

Gross profit is only as accurate as the plate cost and the price behind it. Supplier prices change, recipes drift, and prices are updated. Review the plate costs of the main dishes regularly, and whenever a key supplier changes its prices, so the gross profit of each dish reflects reality.

A gross profit worked out a year ago can be badly wrong today.

The kitchen and the floor make better decisions when they know roughly what each dish earns. A cook who knows a portion of fish earns little extra if it is oversized takes more care with portions. A server who knows which dishes and drinks earn most can suggest them naturally.

Share the numbers in simple terms: which dishes earn most per sale, and which sides and drinks add the most.

In the monthly accounts, gross profit is sales minus the cost of goods sold for the whole venue. It is the same idea as gross profit on a dish, added up across everything sold, including waste, comps and staff meals. The venue's gross profit is usually lower than the sum of each dish's theoretical gross profit, and the difference shows how much is lost between the recipe and the bin.

Here is an illustrative change to a section of mains. The figures are examples.

The section's total gross profit rose, and the steak stayed on the menu.

In servearound, each dish can carry its cost, so the menu report shows gross margin once costs are set, and every dish that sold, with units, checks, revenue, share, unit cost and margin, along with how much of the revenue has a cost behind it. Menu analytics plots each dish by popularity against contribution margin, so the dishes that sell and earn stand apart from those that do neither.

Each menu can carry its own prices, and a selection of prices can be moved together by a percentage or an amount. See Menus and Analytics.

Its net selling price, after tax, minus the cost of the ingredients on the plate.

Gross profit is money per sale; food cost percentage is the cost as a share of the price. They answer different questions.

Because the venue's costs are paid in money. A dish with a higher percentage can earn more per sale.

No. Use the price after VAT or sales tax.

Every cost except the ingredients, including labour, energy, rent and card fees.

By lowering the plate cost through better buying, smart portioning and less waste.

Whenever key supplier prices change, and in a regular review of the main dishes.

Yes. Drinks often earn high gross profit and deserve the same care as the dishes.

Usually, but not if it comes with a price guests will not pay, a smaller portion they notice, or a dish that slows the kitchen at the peak. Weigh it against sales and kitchen time, and against what the dish does for the menu as a whole.

The accounts show gross profit for the whole venue, after waste, comps and staff meals. The figure for one dish is what it should earn if made exactly to the recipe, so the two will never match exactly.

What is gross profit on a dish? Its net price minus its plate cost: the money each sale contributes to the business. Gross profit per dish beats the food cost percentage for decisions, because the bills are paid in money, and a dish with a higher percentage can earn more per sale than one with a lower percentage.

Use gross profit in menu pricing, combine it with popularity to see each dish's total contribution, and raise it through better buying and portioning as well as price. Remember what it leaves out, such as labour and kitchen time, keep plate costs current, check discounts and set menus, and share the numbers with the team.
