How to calculate the cost per serving of a recipe — with a worked example.

Step 1: List what you used, and how much

Write down every ingredient with the amount that went into the recipe, in whatever unit you can match to the package: pounds, ounces, cans, cups, cloves or each. If you’re already weighing ingredients to calculate the calories in a recipe, you can reuse the same list.

Include the oil for the pan, the spices and anything you finish the dish with. Each is small, but together they add up; in the chili below, the oil and spices come to $1.29 of the total.

Step 2: Find the unit price

The unit price is what one unit of the package costs: package price ÷ package size. A 16.9 fl oz bottle of olive oil at $8.99 works out to about 53 cents per fluid ounce. Many US grocery shelf tags print a unit price next to the sale price, and your receipt or the store’s app shows what you paid.

Two details trip people up here:

• Match the units. If the jar is sold by weight (2.5 oz of chili powder) but the recipe uses tablespoons, convert one to the other first. Two tablespoons of chili powder weigh about 16 g, or 0.56 oz. Our recipe measurement conversion chart covers the common cup and spoon weights.
• Price what you bought, not the drained or trimmed weight. A can of beans is priced per can, so count cans. A head of garlic is priced per head, so divide by the number of cloves.

Step 3: Price each line and add it up

For each ingredient, cost = package price ÷ package size × amount used. For the olive oil, that’s $8.99 ÷ 16.9 fl oz × 0.5 fl oz (one tablespoon) = $0.27.

The ground beef price is the Bureau of Labor Statistics average for 100% ground beef in US cities in September 2026. The others are example prices to show the arithmetic; use your own receipt.

The beef alone is 44% of the total, and beef, tomatoes and beans together make up 76%. That pattern is common: the protein and one or two bulky ingredients decide the cost, and the spices and aromatics barely move it. If you only have time to price a few lines carefully, price those.

Step 4: Divide by servings

$15.29 ÷ 6 servings ≈ $2.55 per serving.

The number of servings matters as much as the prices. Count the portions the pot actually gives you, not the number printed on the recipe; if the same chili fills five lunch containers instead of six, each one costs about $3.06. Our guide to working out the serving size of a recipe covers weighing the finished dish and portioning it evenly.

Pantry staples, leftovers and the parts you don’t use

The formula is fixed, but a few choices are yours. Make them once and apply them the same way every time, so your costs stay comparable.

Oil, spices and salt

Price them like everything else, by the amount used. Salt and pepper rarely come to more than a few cents, so it’s fine to skip them. Spice blends and good oil are worth counting: they added $1.29 to the chili.

Ingredients you already had

Use what it would cost to replace them today, not what you paid months ago. The point of the number is to know what the dish costs to make now.

The rest of the package

If you’ll use the other half of the onion or the rest of the broth in something else, count only what went into this recipe. If it’s going to sit in the fridge until it goes off, count the whole package. That gives a more honest number for a recipe that leaves awkward leftovers.

Sale prices and bulk buys

Either use what you actually paid or a regular shelf price, but pick one approach. A recipe priced at this week’s sale price will look cheaper than it usually is.

How to bring the cost per serving down

Sort the lines by cost and start at the top. In the chili, finding the beef for 20% less saves $1.36, more than leaving out every spice and the oil ($1.29).

Swapping canned beans for dried is a good example of a change that adds up. The Nebraska Dry Bean Commission puts a 15 oz can at about 1½ cups of cooked beans, and 1 pound of dry beans at about 6 cups cooked. The two cans in the chili are 3 cups, or about half a pound of dry beans. At the BLS average of $1.67 a pound for dried beans in September 2026, that’s about $0.83 instead of $2.38. The pot drops to $13.74, or about $2.29 a serving, in exchange for soaking and simmering the beans yourself.

Other changes that move the biggest lines: a cheaper cut or a different protein, more beans and less meat, a store brand for canned tomatoes and broth, and buying staples you use often in larger packages when the unit price is lower. Check that a swap still works in the recipe before you count the savings.

If you track calories too, a swap changes both numbers; our guide to calculating calories in a recipe covers how to recount them.

App, spreadsheet or by hand?

By hand or in a spreadsheet is the most accurate, because you use your own receipts. It’s worth doing for the recipes you cook every week: price it once, save the per-serving number with the recipe, and update it when prices change.

In Hireci, each saved recipe has a Recipe cost estimate: the total, the cost per serving, and a cost for each ingredient line, based on the recipe’s amounts and servings. The app labels it as an estimate from a US baseline ingredient price table, and actual prices vary by brand, store, location and season, so treat it as a quick guide rather than your receipt. Find ways to save suggests lower-cost swaps for the expensive lines. The estimate is free to view; Find ways to save includes a few free uses, then needs a Hireci+ subscription. The app is free to download for iPhone, iPad and Android.
