Eggs deliver 34.4 grams of protein per dollar. Plain nonfat Greek yogurt delivers 27.5. Eggs win by about 1.3 times, using USDA figures and 2026 prices, which is the closest matchup we’ve looked at and honestly close enough that the real answer is “either one, and here’s how to pick.”
| Eggs (large) | Greek yogurt (plain, nonfat) | |
|---|---|---|
| Protein per $1 | 34.4 g | 27.5 g |
| Protein per 100 g | 12.56 g | 10.19 g |
| What you buy | 1 dozen | 32 oz tub |
| Price | $2.19 | $3.36 |
| Cost per 100 g | $0.365 | $0.370 |

How close is this race, really?
Look at the last row of that table. Eggs cost 36.5 cents per 100 grams of food. The yogurt costs 37 cents. Half a cent apart. As far as your wallet is concerned, you’re buying the same weight of groceries for the same money.
The entire gap comes from density. Eggs pack 12.56 grams of protein into 100 grams; the yogurt packs 10.19. That’s about 23 percent more protein riding in the same weight, and that’s the whole 1.3 times advantage. No hidden factor, no processing story, no water weight argument.
Which also means the result is fragile. Eggs are priced here at the May 2026 national average of $2.19 a dozen, and anyone who shopped in the last few years knows that number moves like a stock ticker. A dollar swing either direction rearranges this ranking completely. Our protein per dollar study has eggs at 19th of 49 foods and the yogurt at 25th, six spots apart in a list where the leader is nearly three times the winner here.
Which one puts more protein in the fridge?
The yogurt does, which is the fact that surprises people.
A dozen large eggs comes to about 600 grams of edible egg, so at 12.56 grams per 100 grams you’re bringing home roughly 75 grams of protein for $2.19. That’s about a day and a half of the FDA’s 50 gram Daily Value. The 32 ounce tub of Greek yogurt holds 907 grams at 10.19 grams per 100 grams, which is about 92 grams of protein for $3.36.
So the tub wins on total protein and loses on efficiency. If you’re buying for the week rather than optimizing per dollar, one tub covers more meals than one carton. If you’re counting every dollar, the carton is the better rate.
Eggs do have one advantage the numbers hide: they turn into dinner. A sheet pan breakfast hash with eggs and sweet potatoes or a pan of cauliflower fried rice with eggs is a real meal built on 40 cents of protein. Yogurt mostly stays yogurt.
When is Greek yogurt the better buy?
When you need protein without a stove.
That’s not a small category. Yogurt is protein you can eat at a desk, in a car, or at 6 AM before your hands work properly. A high fiber yogurt parfait takes 90 seconds and no pan. Eggs need heat, a skillet, and cleanup, and the whole 1.3 times advantage evaporates the moment you skip breakfast because you couldn’t face the frying pan.
Yogurt also does jobs eggs can’t. It thickens sauces, it stands in for sour cream, it goes savory with cucumber and lemon or sweet with berries. If you keep a no-cook ricotta and berry toast bar style breakfast in rotation, yogurt slides right in.
The tiebreaker isn’t the ranking. It’s which container is empty at the end of the week.
What else in the fridge beats them both?
Not much, and one thing that will annoy you.
| Food | Package and price | Protein per $1 |
|---|---|---|
| Eggs (large) | 1 dozen, $2.19 | 34.4 g |
| Mozzarella (low-moisture part-skim) | 16 oz block, $3.58 | 30.1 g |
| Whole milk | 1 gallon, $4.22 | 29.1 g |
| Greek yogurt (plain, nonfat) | 32 oz tub, $3.36 | 27.5 g |
| Cottage cheese (4%) | 24 oz tub, $2.87 | 26.3 g |
| Cheddar cheese | per lb, $5.69 | 18.2 g |
Whole milk at 29.1 grams of protein per dollar quietly beats both Greek yogurt and cottage cheese, mostly because a gallon is 3,904 grams of food for $4.22. Nobody thinks of milk as a protein buy. The gallon holds about 123 grams of it.
Cottage cheese at 26.3 lands within a rounding error of the yogurt, so pick between those two on taste and use rather than price. We broke that one down separately in cottage cheese vs Greek yogurt.
The wider view is that this whole shelf is mid-table. Dried legumes and whole wheat flour run 73.9 to 97.9 grams of protein per dollar, roughly two to three times what any of these managed, which is the point we made in where eggs really rank. The dairy protein ranking has the rest of the case, and the high protein on a budget guide puts the cheap stuff to work across a full week.
