Edamame vs Oats (dry): which protein is cheaper?

USDA macros joined to current US grocery prices, reduced to the two numbers that decide it: dollars per gram of protein, and protein per calorie.

Oats (dry) is 3.8x cheaper per gram of protein ($0.009/g vs $0.033/g), while Edamame is the leaner choice at 9.9 g protein per 100 kcal against 4.3 g. Budget favours one, a calorie cap favours the other.

A week of protein from each

Hitting a common 100 g/day protein target from oats (dry) alone costs $6.21 a week; from edamame alone, $23.33. That is a gap of $17.12 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 $0.033, so it saves $17.12 a week at a 100 g/day target. Edamame answers a different question: 9.9 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.
