Menu Costing for UK Caterers

Most menu costing advice is written for restaurants. It tells you to cost a plate, apply a target food cost percentage, and put a price on the board. That works when the same dish sells three hundred times a month and a bad price corrects itself slowly.

Catering is a different problem. You cost a whole menu once, for one event, at a guest count that is fixed before you buy anything — and if the number is wrong, there is no second service to average it out. A single mispriced wedding is a month of margin.

This guide covers menu costing as a caterer actually does it: the whole menu at a set guest count, with yield and service style built in, and a blended margin across courses rather than a target percentage applied dish by dish.

Start from the menu, not the dish

The restaurant method costs each dish in isolation and prices each one to hit a food cost percentage. Do that for an event menu and you get a number that is arithmetically correct and commercially useless, because the client is not buying five dishes — they are buying one per-head price for a three-course dinner with canapés on arrival.

The catering method runs the other way:

1. Cost every dish at the event's guest count, not at recipe yield
2. Add yield loss and waste at the level of the whole menu
3. Add the overheads that belong to this event
4. Divide by guest count for a true cost per head
5. Apply a blended margin across the whole menu to reach a sell price

The difference shows up immediately at step one. A recipe that serves four does not scale linearly to eighty: your stock reduces differently in a bigger pan, your trim losses on a whole side of salmon are proportionally lower than on two fillets, and the canapé yield from a tray depends on how big your hands are on the day. Cost at the number you are actually cooking.

The recipe scaling calculator does the quantity arithmetic; our guide to recipe costing for caterers covers the per-dish method that feeds into this.

Yield is where menus leak money

Yield is the proportion of what you buy that reaches the plate. It is the single most under-costed number in catering, because the invoice shows the purchase weight and the client eats the trimmed weight.

Worked example — a 40-cover dinner with a beef main:

Line	Figure
Beef featherblade, purchased	12 kg
Trim and bone loss	18%
Cooking loss (braised, 4 hours)	22%
Yield to plate	12 kg × 0.82 × 0.78 = 7.68 kg
Portion size	180 g
Portions produced	42.6
Purchase price	£11.20/kg
Total spend	£134.40
Cost per portion	£3.15

Cost that same beef on purchase weight and you get £11.20 × (0.180) = £2.02 per portion — 36% under. Across a full menu those gaps compound, and they compound in the same direction every time.

Practical rule: keep a yield figure for every ingredient you buy in a form different from how you serve it. Whole fish, bone-in meat, unpeeled vegetables, anything you braise or roast hard. Ingredients you buy ready to use — cream, butter, dry goods — need no yield adjustment and should not get one.

Service style changes the cost before it changes the price

The same menu costs different amounts depending on how it is served, and this is the adjustment restaurant costing has no equivalent for.

Service style	Portion behaviour	Typical costing adjustment
Plated, served	You control every portion exactly	Cost at portion size, small contingency
Family style / sharing	Guests self-serve from platters	Increase quantities — plan for more than the nominal portion
Buffet	Guests self-serve, first guests take most	Increase quantities noticeably; the popular dishes go fastest
Canapés	Count per head, not weight	Cost per piece × pieces per head

A buffet is not a plated menu served differently — it is a different quantity of food. Costing a buffet at plated portions is the second most common way a caterer loses money on an event, after under-costing yield. Our guide to pricing buffets and event formats covers the per-head ranges each format supports.

Blend the margin across the menu, not within it

Applying a fixed food cost percentage to every dish produces menus nobody wants to eat. The starter that costs 60p to make gets priced at £2, and the beef main gets priced somewhere the client will not go.

Blend instead. Cost the whole menu, decide what the whole menu should sell for, and let the individual dishes sit wherever the food cost lands:

• Low-cost, high-perceived-value dishes carry the menu. Soups, breads, seasonal vegetable sides, most desserts. These are where your margin comes from.
• Expensive proteins are the reason the client booked you. Price them closer to cost and take the margin elsewhere.
• Judge the blend, not the dish. If the whole menu sits at 30% food cost, one dish at 45% is not a problem.

This is where menu costing meets menu design. Our guide to menu engineering for caterers covers how to work out which dishes are actually earning their place once you have costed them.

Overheads belong in the menu price

Ingredients are the visible cost and rarely the largest one. For a typical event the ingredients are somewhere around a third of what the event costs you to deliver. The rest is:

• Your labour and any staff — prep time, service time, travel time. Cost your own hours at a real rate; a menu that only makes sense if you work for nothing is not priced.
• Travel — fuel, time, and a return journey with dirty equipment
• Equipment — hired chafing dishes, serving ware, cool boxes, linen
• Packaging and disposables — foil, cling film, containers, napkins
• Kitchen costs — if you hire prep space, the session fee belongs to the events it produced. See commercial kitchen rental costs.
• Compliance admin — the food safety records, the allergen matrix, the insurance. Small per event, real per year.

Our guide to calculating food cost per head works through a full event including overheads, and the catering cost per head calculator runs the arithmetic before you send a quote.

Check the VAT position before you set the price

If you are VAT registered, the price you quote and the money you keep are not the same number, and for catering the gap is usually the full 20%.

VAT registration is mandatory once your total taxable turnover for the last 12 months goes over £90,000, or when you expect it to go over £90,000 in the next 30 days. Below that you can register voluntarily, and many caterers do not.

The trap for caterers is that food is normally zero-rated, but a supply made in the course of catering is not — the standard rate of VAT is 20% and it applies to most goods and services, including catering supplies. So the moment you register, a menu you priced at £48 per head is a menu that nets you £40 per head unless you re-price. That is a margin event, not an admin event, and it is worth modelling before you cross the threshold rather than after.

There are genuine distinctions inside that rule — delivered cold food the client finishes themselves is treated differently from food you supply under a contract to cater an event. Those are worth understanding properly before you assume everything you sell is standard-rated.

Re-cost when your suppliers do

A menu costed in March and sold in November is a menu costed at March prices. Ingredient costs move, and they rarely move down.

A workable rhythm for a small operation:

• Re-cost the whole menu quarterly, or whenever a supplier sends a price list
• Re-cost immediately on any ingredient that has moved more than about 10%
• Re-cost before you commit to a long-lead booking — a wedding booked fourteen months out at today's prices is a bet, and you can hedge it with a price-review clause in the contract rather than absorbing it
• Keep the old costings. They tell you which ingredients are volatile, which is what lets you build the right contingency in rather than a flat guess

The short version

1. Cost at the event's guest count, not recipe yield
2. Apply a yield figure to everything you buy in a different form from how you serve it
3. Adjust quantities for service style — buffets and sharing platters need more food, not the same food
4. Blend the margin across the whole menu; do not chase a percentage per dish
5. Put labour, travel, equipment and kitchen costs into the per-head number
6. Check your VAT position before setting the price, not after
7. Re-cost quarterly and whenever a supplier moves
