Arby's publishes a combined US Nutrition and Allergen guide that lists calories, protein, carbs, sugar and allergens for every item. Because the menu is built on lean roasted beef and turkey, the protein-per-calorie math is strong: the roast beef sandwiches carry most of their carbs in the bun, and the meat does the rest. Every figure below comes from that published guide.

Half Pound Roast BeefHalf a pound of slow-roasted beef on a bun, with 48g of protein for 610 calories, one of the strongest protein-per-calorie sandwiches at any drive-thru. The Angus Half Pound Cheesesteak carries more total protein at 66g, but costs 1,110 calories.

Lowest calorie (still filling)
Classic Roast Beef23g of protein for 360 calories on a small bun. A Ham & Swiss Melt is close at 380 calories and 26g. For even less, a Roast Beef Slider is 180 calories with 11g of protein, so two sliders match a Classic for calories with more protein.

Keto / low-carb
Half Pound Roast Beef, no bun, or Chicken TendersAlmost all of the carbs in an Arby's roast beef sandwich sit in the bun: a Roast Beef Slider is 18g of carbs on a small roll. Arby's does not publish a bunless figure, so we do not estimate one. Skip the curly fries, which add 49g of carbs for a medium.

Vegan (best plant-based)
Curly Fries (Arby's publishes no vegan entree)Arby's is a meat-first menu and its published guide lists no vegan entree. The curly fries are the main meat-free item at 250 calories for a small, but Arby's states they contain wheat and, where available, are cooked in the same oil as items containing fish. Confirm before ordering.

Gluten-free
Check the separate Menu Items Without Gluten guideArby's states its sandwich buns and rolls contain wheat, and it publishes a separate Menu Items Without Gluten guide. Its curly fries also contain wheat and share fryer oil, so gluten-free orders here take planning. Use the gluten-free guide and tell the team about a gluten allergy.

What Arby's publishes
The most reliable answer to “how many calories is this?” comes from Arby's’s own nutrition data. Chains revise recipes and portions, so we anchor every figure on this page to the chain’s current publication and link directly so you can verify before ordering.
Arby's publishes a combined US Nutrition and Allergen Information guide that lists serving weight, calories, fat, sodium, carbs, fiber, sugar, protein and major allergens for each item.
Arby's states its sandwich buns and rolls contain wheat, so its roast beef and turkey carry most of their gluten and carbs in the bread rather than the meat.
Arby's states that several fried items, including curly fries, chicken tenders and mozzarella sticks, may be cooked in the same oil as items containing fish, where those items are available.
Arby's publishes a separate Menu Items Without Gluten guide, because most of its sandwiches are served on wheat buns.
Arby's is surfaced in Forkiee through GPS-based nearby discovery. Once a location loads, every dish is scored against your goal and diet (calorie target, macros, gluten-free, keto, vegan, the FDA Big 9 allergens), so the best-match orders rise to the top.
The point of this page is the manual version of that: the numbers are Arby's’s, the math is done, and the best order for your goal is in the table above.
