Recipe cost calculator

A roast chicken plate for eight costs $4.16 a portion: $32.31 of ingredients plus a 3% allowance for oil and seasoning. The bone-in chicken is $14.65 of that, 45% of the plate, and it costs $5.86 for each pound that ends up served, not the $3.20 on the invoice, because only 54.6% of what you buy survives trimming and cooking. Leave out the cooking loss and the chicken reads $11.43, which is $0.40 a plate too low. Across the recipe, $8.81 of the ingredient cost, 27%, is paid for and never served.

The calculator costs each ingredient with trim and cooking yields kept separate, converts units, and shows how much to buy, where the waste is and which ingredients move the plate cost. It then gives food cost at your menu price and the price for your target.

Who reaches for this

For each ingredient you enter what you paid and for how much, the quantity the recipe uses and its unit, and the yields. The recipe quantity is the amount that ends up on the plate or in the finished dish. The calculator converts the units, works out the edible-portion cost of the ingredient, and multiplies it by the quantity. The lines add up to the batch cost, and the batch cost divided by the number of portions is the cost per portion.

That cost per portion is the input to the next two questions in a kitchen. The food cost percentage calculator compares it with what the kitchen actually used, and the menu price calculator sets a price from it. Both are only as good as the recipe cost, which is why this page spends its effort on the losses and the units.

Every ingredient has two costs. The as-purchased (AP) cost is what you paid per unit on the invoice. The edible portion (EP) cost is what a usable unit costs after the losses between the delivery door and the plate. The relationship is simple: EP cost = AP cost ÷ yield.

Hospitality textbooks give two examples. A whole turkey at $0.99 a pound with a 36% edible yield has an EP cost of $0.99 ÷ 0.36 = $2.75 a pound. A head of cauliflower at $1.29 a pound with a 60% yield is $2.15 a pound, and a 4-ounce portion costs $0.54. In both, the invoice price is misleading, and the gap grows as the yield falls.

Costing a recipe from the AP price is the most common error, and it always errs in the same direction. It understates the cost of every ingredient with a yield below 100%: meat and fish with bone and skin, vegetables with peel and stems, herbs with stalks. The result is a menu that looks more profitable on paper than it is in the kitchen.

Yield percentage is the share of what you buy that ends up usable: usable weight ÷ as-purchased weight × 100. In a kitchen there are two stages of loss, and they should be measured separately.

They multiply. Bone-in chicken thighs with a 70% trim yield and a 78% cooking yield have an overall yield of 0.70 × 0.78 = 54.6%. A yield test shows how to find them: weigh 10 pounds as purchased, weigh what is left after trimming, and weigh what is left after cooking. If trimming leaves 7.0 pounds and cooking leaves 5.45, the trim yield is 70.0%, the cooking yield is 77.9% and the overall yield is 54.5%. At $3.20 a pound as purchased, the edible-portion cost is $3.20 ÷ 0.545 = $5.87.

What happens if you use only one

Many calculators take a single yield, and it is easy to enter only the trim yield. Costing 2.5 pounds of cooked chicken at the 70% trim yield alone gives 2.5 × $3.20 ÷ 0.70 = $11.43. With both yields it is 2.5 × $3.20 ÷ 0.546 = $14.65. The difference is $3.22 on the batch, $0.40 on a plate. On a dish that sells a thousand times a month, that is $400 of cost that a recipe card does not show.

Measure the recipe quantity the same way as the yield

The yield must match the way the recipe quantity is stated. If the recipe says 5 ounces of cooked chicken per portion, the cooking yield belongs in the cost. If the recipe says 8 ounces of trimmed raw chicken, only the trim yield does, since the cooking loss is already in the portion size. Mixing the two counts a loss twice or not at all, and it is the main reason two cooks costing the same dish get different answers.

Yields are measured, not looked up. They vary with the supplier, the grade, the season, the knife and the cook. Run a test on your own product when you set a recipe, and again when the supplier or the cut changes. The workbook has a sheet for the arithmetic, and three tests averaged are better than one.

Purchase units and recipe units rarely match. You buy butter by the pound and use it by the ounce, buy stock by the gallon and use it by the cup, and buy oil by the litre and use it by the tablespoon. Conversions within the same kind of measure are exact. A pound is 453.59 grams and 16 ounces of weight, a gallon is 3,785 millilitres and 16 cups, and a tablespoon is 14.79 millilitres.

The one conversion you cannot do without a number

Weight and volume do not convert without a density. A cup is a volume, an ounce of weight is a weight, and how many ounces are in a cup depends on what is in the cup. A cup of sifted flour, a cup of packed flour and a cup of sugar all weigh different amounts. If flour comes in a 5-pound bag at $4.00 and a recipe needs 2 cups, you need to know what a cup of your flour weighs. At 120 grams a cup, which is an illustration, 2 cups is 240 grams or 0.53 pounds, and the cost is $0.42.

The calculator asks for grams per cup on any line that crosses from weight to volume, and it flags the line and costs it at zero if you leave the density blank. It does not guess. Counts, such as bunches or lemons, do not convert to weight or volume at all. Weigh a cup of the ingredient as you use it, write the number down, and reuse it.

A baked good, costed per piece

The same method works for a bakery or a home business, where the batch is the unit and the measures are cups. Take a batch of 24 cookies. Two cups of flour at 120 grams a cup, from a 5-pound bag at $4.00, costs $0.42. A cup of butter, 8 ounces, at $4.80 a pound costs $2.40. Two eggs at $0.35 each cost $0.70. The ingredients come to $3.52, and $3.52 ÷ 24 = $0.15 a cookie. Sugar, chips and the oven’s gas would add to it, and the batch size is the number to check: 24 cookies from a batch that really makes 20 would cost $0.18 each.

The example is a roast chicken plate for eight portions. Each portion has 5 ounces of cooked chicken, so the recipe serves 2.5 pounds. Prices, quantities and yields are illustrations.

Add a 3% allowance for the salt, pepper, extra oil and garnish that no one weighs, $0.97, and the batch costs $33.28. Divided by eight portions, the cost per portion is $4.16. At a $16.00 menu price, food cost is 26.0% and $11.84 is left per plate before labor and overhead. At a 30% target food cost, the price would be $4.16 ÷ 0.30 = $13.87.

Two lines carry most of the cost. The chicken is 45% of the ingredient cost, and the green beans and herbs add another 27%. A costing that gets those right is close, and one that gets them wrong is not, whatever it does with the lemons.

Check the card against a plated dish

Before trusting a recipe cost, plate one portion the way the line does and weigh what is on it. If the card says 5 ounces of cooked chicken and the plate carries 6, the chicken costs 20% more than the card says: $14.65 becomes $17.58 across the batch, and the plate rises from $4.16 to $4.54. Do this for the highest-cost ingredient on each main dish, at a busy moment and not a quiet one, since portions drift when the line is rushed.

The same yields answer the ordering question. The as-purchased quantity you need is the quantity served divided by the yield: quantity needed = portions × portion size ÷ yield. To serve 2.5 pounds of cooked chicken at a 54.6% yield you must buy 2.5 ÷ 0.546 = 4.58 pounds. Without the yield, you would order 2.5 pounds and be short by almost half.

Scaling works the same way. A catering order for 120 covers is 15 times the eight-portion batch, so the chicken order is 4.58 × 15 = 68.7 pounds. The yield does not change with the batch size, although a very large batch may trim and cook differently, so retest when you scale up by a large factor.

The calculator shows the cost of the losses on each line, the difference between the cost at the edible-portion price and the cost if everything bought were usable. In the example, $8.81 of the $32.31, or 27%, is paid for and never served. The chicken accounts for $6.65 of it, the herbs $1.03, the potatoes $0.59 and the green beans $0.53.

This is the number to look at when you want to reduce cost without touching the plate. Trim losses can be reduced with a better cut, a better knife skill or a different form of the product: boneless thighs cost more per pound and yield more, and the comparison is a matter of edible-portion cost, not price per pound. Cooking loss can be reduced with a different method. And some trim is not waste at all: bones make stock, and trimmings can go into a staff meal or a sauce, which reduces the true cost of the loss.

Comparing forms of the same product

Yield is the reason the cheapest product per pound is not always the cheapest per plate. Suppose boneless thighs cost $5.50 a pound with an 88% trim yield and a 78% cooking yield, which is 68.6% overall. The edible-portion cost is $5.50 ÷ 0.686 = $8.01 per pound, against $5.86 for the bone-in thighs. The bone-in product still wins on ingredient cost here, but with a labor cost to bone them the gap is narrower than it looks, and with a different price it could reverse. Compare on edible-portion cost, and then on labor.

Not every price matters equally. A 10% rise in the chicken adds $0.19 to the plate. A 10% rise in the green beans adds $0.07, and in the herbs $0.04. The share of the plate an ingredient takes tells you how closely to watch its price: the top two or three lines usually carry most of the exposure.

Use it to decide where to negotiate, where to lock a price and which ingredients a substitution could protect. It also tells you which recipe costs need refreshing first when a price moves. A change in the price of lemons can wait. A change in the price of chicken should not.

Sauces, stocks and other sub-recipes

A sauce that goes on several dishes should be costed once. Cost the sauce as its own recipe, with its ingredients, yields and number of servings, and use its cost per serving as a line in each dish. If a pan sauce costs $6.40 a batch and yields 16 servings, it is $0.40 a serving, and a plate that uses one serving carries $0.40. In the calculator, enter it as a line priced at $0.40 for each, with a recipe quantity of one each per portion. When the sauce recipe changes, one update flows to every dish.

Sundries

Salt, pepper, cooking spray, a splash of oil and a sprig of garnish are too small to weigh on every plate and too large to ignore across a menu. An allowance as a percentage of the ingredient total covers them. The calculator uses 3% as an illustration, which adds $0.97 to the example batch. To find your own, cost a few dishes in full detail and see how much the small items add to the total. An ingredient that is small on one plate but used everywhere, like the oil, can deserve its own line.

Portions

The cost per portion depends on how many portions the batch really produces at the size you plate. A recipe that says it serves eight may serve seven at your portion size. Weigh a few finished plates and count what the batch yields. If the batch makes seven portions instead of eight, the cost per portion is $33.28 ÷ 7 = $4.75, not $4.16. Portion control is a cost control, and the plate you weigh is the plate you cost.

Keeping recipe cards current

A recipe cost is a snapshot, and the useful habit is a routine. Keep prices in one place, such as a purchasing sheet, so that one change flows to every recipe that uses the ingredient. Review the top ingredients by cost every month, and the rest each quarter. Retest yields when you change a supplier, a cut or a method, and date every card so that you know how old its numbers are.

Plate waste, food that comes back uneaten, is a real cost that a recipe card does not capture. It shows up as a gap between theoretical and actual food cost, and the food cost percentage page shows how to find it. The recipe card describes the plan, and the period figure describes what happened.

The recipe cost is the start of a price and not the end of one. Divide the cost per portion by the menu price to get the dish’s food cost percentage, and divide by the target percentage to get the price that would hit it. The example plate is 26.0% at $16.00 and needs $13.87 for a 30% target. Those are the quick answers.

The rest of the price decision, direct labor, overhead, delivery, and how the dish fits in the mix, is on the menu price calculator. Once the dish is on the menu, the food cost percentage calculator compares this theoretical cost with what the kitchen actually used, and the gap between them shows whether the recipe card describes what happens on the line. For a product you make in batches and sell by the unit, the cost per unit calculator covers fixed and variable costs beyond the ingredients.

Take the cost per portion to the menu price calculator to set a price, or to the food cost percentage calculator to check it against what the kitchen used.
