A week of protein from each

Hitting a common 100 g/day protein target from oats (dry) alone costs $6.21 a week; from ground beef 90/10 (raw) alone, $38.50. That is a gap of $32.29 every week for the same protein. In practice you mix sources: the planner computes the cheapest mix for your exact target and calorie cap, live from the same dataset.

Budget says one, calories say the other

Oats (dry) costs $0.009 per gram of protein against $0.055, so it saves $32.29 a week at a 100 g/day target. Ground beef 90/10 (raw) answers a different question: 11.4 g of protein per 100 kcal against 4.3 g, which is what matters once calories, not dollars, are the thing you run out of first.

What the calories cost you

Getting 30 g of protein from oats (dry) brings 691 kcal with it. On a 2,000 kcal day, three servings would be most of your budget before anything else goes on the plate. That is fine when you are eating at maintenance or building, and it is the reason this food falls apart on a cut no matter how good the price per gram looks.

The gap here is 6.2x, which is unusual

Most matchups in this dataset land inside 2x. Ground beef 90/10 (raw) costing 6.2x what oats (dry) does for the same gram of protein means you are buying something other than protein: processing, shelf stability, convenience or flavour. Worth paying for sometimes, but name it, because at a 100 g/day target that gap is $32.29 a week and $1678.92 a year.

One of these is a convenience purchase

Ground beef 90/10 (raw) ranks #23 of 25 on cost per gram of protein, near the bottom. It is not a bad food, it is an expensive way to buy protein: $1.65 per 30 g against $0.27 for oats (dry). If it is in your basket for the protein, swap it. If it is there because it travels well or you enjoy it, that is a different and perfectly good reason.

On a cut these are not comparable

Ground beef 90/10 (raw) carries 2.6x the protein per calorie that oats (dry) does. When you are eating at a deficit, that ratio is the whole game: the same 30 g of protein arrives with 264 kcal from one and 691 kcal from the other. The cheaper option stops being cheaper once you count what you had to give up elsewhere to fit it in.
