Arby’s Classic Roast Beef: Price, Calories and Nutrition (2026)

The Classic Roast Beef is the sandwich that built Arby’s. Thinly sliced roast beef, cooked in-store and piled onto a toasted sesame seed bun. No fancy sauces in the standard build, no cheese, just beef and bread. It has been on the menu since Arby’s opened its first restaurant in 1964, and it is still the sandwich everything else on the menu is measured against. In 2026 the Classic Roast Beef carries 360 calories and a price starting from $4.79. Here is the current price, the calorie count, and the full nutrition breakdown.

Prices vary by location because most Arby’s restaurants are franchise-operated and owners set their own prices, with most markets landing between $4.79 and $5.39. The 360 calorie figure covers one standard Classic: sliced roast beef on a toasted sesame seed bun, no sauce added. Arby’s Sauce and Horsey Sauce are free but add calories.

What is in the Classic Roast Beef

The build could not be simpler. Arby’s roasts whole cuts of beef in the restaurant every day, slices them thin, and stacks the slices on a toasted sesame seed bun. That is the entire sandwich. The beef is the point: slow-roasted, seasoned, and shaved thin so it drapes over the bun instead of sitting in a slab.

At 360 calories with 23 grams of protein, the Classic is one of the lightest full-size sandwiches on the Arby’s menu. Compare that to the Beef ‘N Cheddar at 450 calories or the Smokehouse Brisket at 600, and the Classic starts to look like the disciplined choice. The 14 grams of fat comes almost entirely from the beef itself. Sodium sits at 970 mg, which is 42 percent of the daily guideline, so it is not a low-sodium food, but it is moderate for fast food.

The bun matters more than people expect. The toasted sesame seed bun gives the sandwich structure and a slight crunch on the outside, which keeps the thin-sliced beef from making it soggy.

One thing worth knowing: the beef is the same beef used across the roast beef lineup. The Classic is the reference point for the whole menu: if you like it, the Double and Half Pound upgrades are straightforward.

Classic Roast Beef nutrition facts

Full nutrition breakdown for one standard Classic Roast Beef, based on Arby’s official US nutrition data. Standard build: thinly sliced roast beef, toasted sesame seed bun. No sauce added.

Nutrient	Amount per sandwich
Calories	360
Total fat	14g
Total carbohydrates	37g
Protein	23g
Sodium	970mg

The 23 grams of protein is the standout number. For a 360 calorie sandwich, that is a strong ratio, and it is why the Classic keeps you full longer than its size suggests. The 14 grams of fat is modest for a beef sandwich because there is no cheese or creamy sauce in the standard build. Carbohydrates at 37 grams come almost entirely from the bun.

For context, the Classic is the lowest-calorie sandwich in the Arby’s roast beef family. Adding Arby’s Sauce adds 15 calories, and a packet of Horsey Sauce adds 60. Those sauces are free and they transform the sandwich, so most people add one. Just know that the published 360 calorie figure assumes you eat it plain.

Classic Roast Beef ingredients and customization

The standard ingredient list is short: roast beef (beef, water, salt, sodium phosphates), a sesame seed bun (enriched wheat flour, sesame seeds, yeast), and nothing else. Arby’s states the beef is 100 percent real beef, roasted in-store daily.

Customization happens at the sauce station. Arby’s Sauce is a sweet, tangy tomato-based sauce, 15 calories a packet. Horsey Sauce is a creamy horseradish-mayo blend, 60 calories a packet, and it is the cult favorite. Both are free on request. You can also ask for the sandwich with no bun if you are cutting carbs, and most locations will oblige.

The paid upgrades are straightforward: the Double Roast Beef doubles the meat for about $1.50 to $1.70 more, and the Half Pound goes further still. But the honest advice is this: the Classic is already the finished product.

Allergens

The Classic Roast Beef contains wheat and gluten (bun), soy (in the beef seasoning and bun), and sesame (bun). The bun may contain milk. Cross-contact with all major allergens is possible on the shared prep line and in the fryers. Always check Arby’s current allergen information if you have a serious allergy, since recipes vary by supplier and region.

Classic Roast Beef vs Beef ‘N Cheddar Classic

The two most famous Arby’s sandwiches invite a direct comparison. The Classic Roast Beef: plain sliced beef on a sesame bun, 360 calories, 14g fat, 23g protein, from $4.79. The Beef ‘N Cheddar Classic: the same beef topped with cheddar cheese sauce and Red Ranch on a toasted onion roll, 450 calories, 20g fat, 23g protein, from $5.29.

The Beef ‘N Cheddar wins on flavor intensity. The cheddar sauce and the zesty Red Ranch give it a richness the plain Classic does not have. But it costs about 50 cents more and adds 90 calories, almost all of it from the cheese sauce and ranch. The protein is identical at 23 grams, so you are paying for flavor, not fuel.

Pick the Classic when you want the pure roast beef experience, the lower calorie count, and the lower price. It is also the better canvas for sauces, since Horsey Sauce on a plain Classic is arguably better than anything on the Beef ‘N Cheddar. Pick the Beef ‘N Cheddar when you want the indulgent, cheesy version and do not mind the extra 90 calories.

Getting the best value on the Classic Roast Beef

At from $4.79, the Classic is one of the cheapest full-size sandwiches at any national chain. It is genuine value, not a loss-leader.

The 2 for $7 style deals Arby’s runs regularly often include the Classic Roast Beef. Two Classics for $7 drops the per-sandwich price to $3.50, which is the best price this sandwich ever reaches.

Happy Hour (2 PM to 5 PM at participating locations) has featured the Classic Beef and Cheddar slider and small fries at $1 to $2, but the full-size Classic is the better lunch.

Sauces are free, so build your flavor with Arby’s Sauce and Horsey Sauce instead of paying for cheese.

The Arby’s app runs regular BOGO and percentage-off offers. A BOGO on the Classic makes it the cheapest premium sandwich in fast food.
