Price per serving is the better number to compare, because it counts only the food that ends up on the plate. Price per pound also counts the bones, skin, rinds, stems and water that never get eaten. Use price per pound as the starting point, since it's what the shelf tag shows, then turn it into price per serving with one division.
Why can a cheaper price per pound cost more per serving?
A pound of raw food is not a pound of food you eat. Bone-in chicken thighs lose their bones and some fat, broccoli heads lose their stems, and spinach shrinks in the pan. The share you do eat is called the yield, and it varies a lot from one cut or form to the next.
USDA measures yields for school and child care meal programs in its Food Buying Guide. Its meat yield table (last updated in August 2025) shows how much cooked meat one pound of raw meat gives you:
| Cut, as bought | Cooked meat from 1 lb raw |
|---|---|
| Ground beef, up to 20% fat | 0.74 lb, cooked and drained |
| Boneless, skinless chicken breast pieces | 0.73 lb |
| Boneless, skinless chicken thighs | 0.63 lb |
| Boneless pork loin chops, 1/4-inch fat trim | 0.59 lb |
| Bone-in chicken thighs, skin on | 0.52 lb with skin, 0.43 lb without |
| Bone-in pork loin chops, 1/4-inch fat trim | 0.45 lb |
| Whole chicken, no neck or giblets | 0.44 lb with skin, 0.36 lb without |
So a whole chicken gives you a little over a third of its raw pounds as cooked meat if you skip the skin, while boneless breast pieces give you nearly three quarters.
How do you turn price per pound into price per serving?
You need three numbers: the price per pound, the yield, and how much you serve each person.
- Find the price per pound on the shelf tag or package.
- Divide it by the yield. That gives you the price per pound of food you actually eat.
- Multiply by your portion in pounds. A 4-ounce portion is 0.25 lb, a 6-ounce portion is 0.375 lb.
As one line: price per serving = price per pound ÷ yield × portion in pounds.
Here's a worked example with example prices, not quotes from any store. Say bone-in, skin-on chicken thighs are $1.99 a pound and boneless, skinless thighs are $3.49 a pound, and you serve 4 ounces of cooked meat each.
- Bone-in, skin eaten: $1.99 ÷ 0.52 × 0.25 = about $0.96 a serving
- Bone-in, skin removed: $1.99 ÷ 0.43 × 0.25 = about $1.16 a serving
- Boneless, skinless: $3.49 ÷ 0.63 × 0.25 = about $1.38 a serving
At those example prices the bone-in thighs still win, even though you throw away part of every pound. The boneless thighs cost 75% more per pound but only about 20% more per serving if you remove the skin from the bone-in ones. That gap is the whole point: the shelf tag overstates the difference.
When is bone-in cheaper than boneless?
You don't have to redo the math every trip. Divide one yield by the other and you get a break-even point: the bone-in or whole option is cheaper per serving whenever its price per pound is below that share of the boneless price. These come straight from the USDA yields above.
| Comparison | Bone-in or whole is cheaper per serving when it costs less than |
|---|---|
| Bone-in thighs, skin eaten, vs boneless skinless thighs | 83% of the boneless price |
| Bone-in thighs, skin removed, vs boneless skinless thighs | 68% of the boneless price |
| Bone-in pork loin chops vs boneless pork loin chops | 76% of the boneless price |
| Whole chicken, skin eaten, vs boneless skinless breast pieces | 60% of the boneless price |
| Whole chicken, skin removed, vs boneless skinless breast pieces | 49% of the boneless price |
If boneless thighs are $4.00 a pound, bone-in thighs are the better buy below about $3.30 if you eat the skin, or below about $2.73 if you don't. A whole chicken has to cost about half as much per pound as boneless breast before it comes out ahead on meat alone, though the carcass can go into stock, which this table doesn't count.
Does price per pound mislead for fruits and vegetables too?
Yes, and sometimes in the opposite direction from what you'd guess. USDA's Economic Research Service publishes average retail prices for fruits and vegetables both per pound and per cup equivalent, a standard serving of the edible part. Its method adjusts each price for peels, cores, stems and cooking losses. National averages in 2023:
| Item | Price per pound, 2023 | Price per cup equivalent, 2023 |
|---|---|---|
| Corn, fresh | $2.10 | $1.42 |
| Corn, frozen | $1.83 | $0.69 |
| Corn, canned | $1.22 | $0.68 |
| Broccoli heads, fresh | $3.02 | $1.32 |
| Broccoli florets, fresh | $3.08 | $1.05 |
| Broccoli, frozen | $2.57 | $1.00 |
| Pineapple, fresh | $0.67 | $0.48 |
| Pineapple, canned in juice | $1.72 | $0.93 |
| Spinach, fresh, eaten raw | $4.50 | $0.69 |
| Spinach, fresh, cooked | $4.50 | $1.93 |
| Spinach, frozen | $2.47 | $1.19 |
A few things stand out:
- Frozen corn costs about 50% more per pound than canned, yet the two cost the same per cup in 2023. Fresh corn on the cob costs about twice as much per cup as either, because only about half of what you buy is kernels.
- Broccoli heads and florets cost about the same per pound, but heads cost about 26% more per cup. You're paying for the stems.
- Whole pineapple yields only about half its pounds as fruit, and it still cost about half as much per cup as canned.
- The same bag of fresh spinach costs nearly three times as much per cup equivalent cooked as raw, because it cooks down so far (for raw leafy greens, ERS counts 2 cups as one cup equivalent). If it's going into a hot dish, frozen spinach cost less per cup.
These are national averages, so your prices will differ. The method still works with any price you see: divide by the yield, then multiply by your portion.
Are dry beans cheaper than canned per serving?
Yes, by close to three to one in the example below, even though price per pound points the other way. A can is part liquid, while a bag of dry beans swells as it cooks. USDA's Food Buying Guide puts one pound of dry pinto beans at about 5 1/4 cups cooked and drained, and a pound of canned pintos at under 1 1/2 cups heated and drained.
With example prices of $1.79 for a 1-pound bag and $1.19 for a 15-ounce can, that works out to about $0.34 per cup cooked from dry and about $0.92 per cup from the can, even though the can works out cheaper per pound. The can buys you time, since dry beans need soaking and simmering.
When is price per pound the right number to compare?
Price per pound works on its own when the yield is the same on both sides. That covers two boneless packages of the same cut in different sizes, two brands of the same canned good, or ground meat at the same fat level. In those cases the unit price on the shelf tag already tells you which is cheaper per serving, and you can skip the division.
Once the two options differ in bones, skin, peel, stems or form (fresh, frozen, canned or dry), convert to price per serving before you decide.
