How to Calculate Food Cost Percentage in Australia

Food cost percentage shows how much of a menu item's selling price is used by its ingredients. The basic formula is ingredient cost divided by selling price, multiplied by 100. If a dish costs $6.00 in ingredients and sells for $24.00, its food cost percentage is 25%.

That calculation is simple, but a useful result depends on accurate recipes, current supplier prices, realistic yields, consistent portions and correct treatment of GST. Food cost percentage is also only one part of profitability. Labour, rent, utilities, payment fees, cleaning, packaging, repairs, administration and waste still need to be covered.

This guide explains how an Australian café, restaurant, bar, pub or food-truck operator can build a reliable recipe cost, calculate food cost percentage and use the result without treating one percentage as a universal answer.

The food cost percentage formula

Use this formula for an individual menu item:

Food cost percentage = ingredient cost ÷ selling price × 100

Worked example:

• ingredient cost: $6.00;
• selling price: $24.00; and
• calculation: $6.00 ÷ $24.00 × 100 = 25%.

The result means that ingredients account for 25 cents of each dollar of the stated selling price. It does not mean the remaining 75 cents is profit. The balance still has to contribute to every other cost of operating the business.

You can also rearrange the formula to produce an indicative selling price from a chosen percentage:

Indicative selling price = ingredient cost ÷ target food cost percentage

If an item costs $6.00 and you use 30% as a planning assumption, the calculation is $6.00 ÷ 0.30 = $20.00. This is a starting point, not an automatic price. You still need to consider GST treatment, labour, market position, customer value, portion size and the rest of the menu.

Decide whether your figures include GST

Use a consistent GST basis throughout the calculation. Mixing a GST-inclusive selling price with GST-exclusive ingredient costs can distort the result.

Many café and restaurant sales are taxable. The Australian Taxation Office explains that GST applies to food consumed on the premises and to hot food supplied for consumption away from the premises. Other food sales can have different treatment. Review the current ATO guidance about GST and food and obtain accounting advice for your business and menu.

For internal management reporting, many businesses compare GST-exclusive sales with GST-exclusive costs. Others use GST-inclusive figures in a simple operational calculator. Either method can produce a usable percentage if the numerator and denominator are on the same basis. Document the approach and use it consistently.

Build an accurate recipe cost

The most common food-costing error is using an estimate instead of a controlled recipe. A recipe cost should identify every ingredient, the purchase unit, purchase price, usable quantity and quantity used in the dish.

Step 1: record the purchase unit and price

Start with the current invoice or supplier price. Record the exact purchase unit: kilograms, litres, cartons, bottles, tins or individual pieces. Include freight or other directly attributable purchasing costs if your costing method requires them.

Example:

• feta: 2-kilogram tub costing $32.00;
• purchase-unit cost: $32.00 ÷ 2,000 grams = $0.016 per gram; and
• recipe quantity: 80 grams × $0.016 = $1.28.

Do not keep using the price from the day the menu was designed. Recheck high-value or volatile ingredients whenever supplier pricing changes.

Step 2: account for usable yield

The purchased weight is not always the usable weight. Trimming, peeling, bones, shells, cooking loss and spoilage can reduce yield.

If 1 kilogram of an ingredient costs $10.00 but only 800 grams is usable, the usable cost is $10.00 ÷ 800 grams, or $0.0125 per usable gram. A 100-gram usable portion costs $1.25, not $1.00.

Measure actual yield for ingredients that materially affect the result. Do not create unnecessary administration for trivial items, but do not ignore a recurring 15% or 20% loss on an expensive product.

Step 3: cost every ingredient

Include oils, sauces, garnishes, seasonings, bread, sides and other items that are routinely served. Small ingredients may appear insignificant, but repeated omissions can materially understate the cost of a high-volume item.

Decide how the business will handle very small quantities such as salt or fryer oil. You might cost them directly, use a documented allowance or allocate them through another controlled method. The important point is consistency.

Step 4: include packaging where relevant

For takeaway and delivery items, packaging can be a direct product cost. Include containers, lids, cups, napkins, cutlery, labels, bags and platform-specific packaging when appropriate.

Keep packaging visible as a separate line if that helps the team understand why takeaway and dine-in versions have different costs.

Step 5: confirm the recipe yield and portion

A batch recipe must be divided by the number of saleable portions it actually produces.

If a soup batch costs $48.00 and produces 20 consistent servings, the ingredient cost is $2.40 per serving. If actual service produces only 16 servings, the cost is $3.00. That difference can come from an inaccurate yield assumption or uncontrolled portions.

Use the same ladles, scoops, scales, glasses and preparation instructions during costing that staff will use in service.

A complete worked café example

Consider a chicken salad sold for $22.00. The controlled recipe includes:

• chicken portion: $3.40;
• leaves and vegetables: $1.35;
• dressing: $0.42;
• grains or garnish: $0.68;
• bread or side: $0.75; and
• takeaway packaging allowance: $0.60.

Total direct cost is $7.20.

The food cost percentage using the stated selling price is:

$7.20 ÷ $22.00 × 100 = 32.73%

Round only for reporting; retain sufficient precision in the underlying calculation. The manager can now ask better questions:

• Is the recipe and portion accurate?
• Is the price on the same GST basis as the cost?
• Does the item require unusually high preparation time?
• Is packaging always used or only for takeaway orders?
• Is waste increasing the actual cost above the theoretical cost?
• Does this product support another commercial purpose, such as strong customer value or menu balance?

The answer is not automatically to increase the price or reduce the portion. The percentage is a diagnostic measure that supports a broader decision.

Theoretical food cost versus actual food cost

Recipe costing produces a theoretical cost: what ingredients should cost if purchasing, yield, portioning and sales match the plan.

Actual food cost looks at what the business really spent and sold over a period. A common overall formula is:

Opening food inventory + purchases − closing food inventory = food used

Then:

Actual food cost percentage = food used ÷ relevant food sales × 100

Use like-for-like categories and periods. If beverage purchases are included in the numerator but only food sales are used in the denominator, the result will be misleading. If stock counts are inconsistent, the percentage can move for administrative reasons rather than genuine performance.

The gap between theoretical and actual cost can point to:

• over-portioning;
• preparation or spoilage waste;
• unrecorded staff meals;
• complimentary items, refunds or voids;
• theft or stock loss;
• invoice or stock-count errors;
• incorrect recipes;
• price changes not reflected in costing; or
• sales being allocated to the wrong category.

Investigate patterns rather than accusing people based on one calculation.

Why receiving and storage affect food cost

Cost control begins before an ingredient reaches the recipe. Damaged, unsafe or incorrectly delivered stock can create both financial loss and food-safety risk.

FSANZ advises food businesses to take practical steps to ensure deliveries are protected from contamination, identifiable and at the correct temperature where relevant. Review the current guidance on receiving food safely and adapt receiving checks to the business.

Storage practices also affect shelf life, spoilage and usable yield. FSANZ's food-storage guidance covers contamination protection, temperature control, date marking and stock rotation. Food-cost improvement must never involve serving unsafe or unsuitable food.

Useful controls include:

• receiving deliveries when a trained person is available;
• checking quantities, condition, dates and agreed temperatures;
• recording shortages and credits promptly;
• labelling opened or prepared products consistently;
• rotating stock using the business's documented system;
• storing raw and ready-to-eat foods appropriately; and
• recording waste by item and reason.

Do you need one target food cost percentage?

There is no single percentage that is correct for every Australian hospitality business or every menu item. A viable range depends on concept, labour model, rent, service style, sales mix, portion size, customer expectations, competition and other operating costs.

Avoid copying an industry number without understanding what it includes. A lower food cost percentage is not always better. An inexpensive item may require substantial labour, while a higher-cost item might be simple to prepare and attractive to customers.

The Australian Government's pricing strategy guidance recommends calculating the total cost of making and supplying the product or service, then considering value and profit. Food cost is therefore one input into pricing, not the whole method.

Review the menu as a portfolio. Some items can carry a stronger contribution, while others provide accessibility, perceived value or a reason to visit. Assess popularity and contribution together.

Food cost percentage and labour cost

Do not try to fix a labour-intensive item solely by changing an ingredient. Record how long preparation and service take, which skill level is required and whether the item creates bottlenecks.

Employment costs must reflect current obligations. Awards, classifications, penalty rates, allowances and minimum pay rates can change. The Fair Work Ombudsman's restaurant and café industry information is a starting point, but businesses should obtain advice for their actual arrangements.

An item with a 24% ingredient cost can still be weak if it absorbs excessive labour or slows service. Conversely, an item with a higher ingredient percentage may make sense if it is fast, popular and supports strong contribution in the wider order.

A practical monthly food-cost review

Use a repeatable process rather than recosting the whole menu only when cash becomes tight.

1. Update invoice prices for the most material ingredients.
2. Review recipe yields and portions for high-volume and high-value items.
3. Recalculate theoretical cost for changed recipes.
4. Complete a consistent stock count.
5. Calculate actual food cost for the same sales period and category.
6. Review waste, credits, transfers, staff meals, voids and complimentary items.
7. Compare theoretical and actual results.
8. Assign specific actions with owners and review dates.

Useful actions might include correcting a supplier price, retraining a portion, changing a preparation batch, improving stock rotation, pursuing a missing credit or reviewing a selling price.

Common food-costing mistakes

Using old supplier prices

An accurate recipe becomes inaccurate when prices change. Set a review trigger for material increases rather than waiting for an annual menu update.

Ignoring yield and waste

Purchase weight is not always usable weight. Measure significant trimming and cooking losses, then record avoidable waste separately.

Leaving out small ingredients

Garnishes, sauces and oils accumulate across hundreds of sales. Use a consistent policy for minor ingredients.

Mixing GST-inclusive and GST-exclusive figures

Choose one basis, document it and apply it to both cost and sales figures.

Treating the balance as profit

Food cost percentage excludes most operating expenses. A 25% result does not mean a 75% profit margin.

Setting prices from a percentage alone

Check labour, overheads, demand, customer value, competition, sales mix and operational complexity before finalising a price.

Frequently asked questions

What is a good food cost percentage for an Australian café?

There is no universal answer. Use your own full cost structure, menu mix and commercial objectives. Compare consistent internal results over time instead of treating an external benchmark as a guarantee.

Should food cost include labour?

The standard menu-item food cost calculation usually focuses on ingredients and directly included items such as packaging. Labour should still be measured and considered in pricing and profitability decisions.

Should I use the menu price including GST?

Use a consistent basis. Many internal reports compare GST-exclusive sales and costs, but businesses may use a different documented approach. Confirm GST treatment with the ATO guidance and your accountant.

How often should recipes be recosted?

Review high-volume, high-value or volatile items whenever material supplier prices, yields or portions change. A scheduled monthly review can be useful, with a fuller menu review at appropriate intervals.

Why is actual food cost higher than recipe cost?

Possible causes include over-portioning, waste, stock loss, invoice errors, unrecorded meals, incorrect counts, old recipe prices or an inaccurate sales mix. Investigate the data and process before deciding on corrective action.

Your next step

Choose five high-volume menu items and build a controlled recipe cost for each one. Record the purchase unit, current price, usable yield, recipe quantity, portion yield, packaging and selling price. Calculate the food cost percentage and identify where better information is needed.
