FastFuel
A menu tells you what things cost and how big they are. It won't tell you which one actually keeps you full until dinner. So this ranks everything on protein, fiber, fat and how much food you're getting, then divides by what you pay.
Fair warning: a $1.79 Bean Burrito gets you 2.0× the fullness per dollar of the $11.49 Monster Angus Burger. Cheap food winning is the whole reason to score it this way.
What have you got?
The prices in here are rough national estimates, not your store's. Per-dollar scoring divides by price, so yours are the ones that matter — type them into any row and the ranking follows. California, Hawaii and the Northeast tend to run 15–25% above these.
Optional — fill this in and it'll tell you what to order.
A day's worth of food is a lot more than one sitting, so this changes the answer quite a bit.
Everything, ranked
Most fullness for your money. Use this when it's the cash that's tight.
A 10 just means best of whatever you're looking at. Pick one chain and everything rescales. Prices are editable — type yours in the box and press Enter, and the list re-sorts.

Score something that isn't on the list
Copy the numbers off the label, or off whatever you're about to cook. It gets scored against all 116 items, so you can see where it lands.
About the numbers
Where the prices come from: mostly hand-collected national estimates, stamped 2026-07, and a minority carry a cited source. Fast food isn't priced nationally, so treat every one of them as a starting guess rather than a fact — your store is the authority, and the boxes are there so you can say so.
The score leans mostly on protein and fiber, with some credit for fat and for how much actual food you get per calorie. Ultra-processed stuff gets marked down, because processing messes with the signals that tell you you're full.
Nutrition figures are the sturdier half — they come from what the chains publish, though your real order still won't match exactly. Grocery items are pinned to USDA entries. And this measures fullness per dollar, not health. It isn't diet advice.
