Wendy’s vs Jack in the Box: Prices, Menu & Who Wins in 2026

Wendy’s wins this matchup on price transparency, value deals and chicken, while Jack in the Box wins on menu breadth and late-night variety. Dave’s Single (560 calories) and the Jumbo Jack (520 calories) are close on calories, but the Jumbo Jack has far less sodium, and Jack’s tacos, egg rolls and curly fries give it a menu Wendy’s cannot match.

Wendy’s is the better everyday choice for a burger-and-fries run, a chicken sandwich or a cheap bundle. Jack in the Box is the better choice when you want something different from a burger or a snack-heavy order. One recent comparison looks only at which chain is healthier, and an older 2024 comparison is now stale, with vague prices and no current nutrition figures. This post does the full job, with Jack in the Box calories and sodium checked against its own 2025 Nutrition Facts PDF, effective November 2024.

One honest note before the tables. Jack in the Box publishes no national prices, so Jack in the Box prices here are marked TBC rather than guessed. Wendy’s prices are shown as the ranges used across this site. Wendy’s lets you plan what a meal will cost before you order; with Jack in the Box, check the menu at your local restaurant.

The verdict, category by category

Overall, Wendy’s takes the win for most people, most of the time: you know what you will pay, the chicken sandwich is lighter, and the value bundles are easy to find. Jack in the Box takes the win for variety: if you want a burger, a taco and an egg roll in the same bag, or curly fries instead of regular fries, there is no contest.

Wendy’s vs Jack in the Box: the basics

Jack in the Box is almost twenty years older than Wendy’s and was a drive-thru pioneer, which is why its menu still feels like a roadside stop: a bit of everything, in one order. Wendy’s is younger and narrower by design, with a short, focused menu. That focus is a strength when you know what you want, and a weakness when you do not want a burger at all. Wendy’s has 5,570 US locations; Jack in the Box is a western and southern chain for the most part, and its US location count is TBC here because it was not verified for this post.

The burger duel: Jumbo Jack vs Dave’s Single

Dave’s Single is Wendy’s fresh, never frozen quarter-pound burger, priced at $5.89-$6.99. The Jumbo Jack is Jack in the Box’s signature burger, and it is the lighter of the two: 520 calories against 560, and 700 mg of sodium against 1,170 mg. That is a 470 mg sodium gap, a real difference if you are watching salt. Wendy’s wins on price, because its price is published and Jack’s is not, but Jack in the Box wins the nutrition argument for the flagship burger.

Two things stand out. The Jumbo Jack Cheeseburger, at 600 calories, is lighter than Dave’s Double at 810. And the heaviest burger here is not the Baconator: it is Jack’s Bacon Double Smashed Jack, at 1,120 calories and 2,070 mg of sodium. At the entry level, Wendy’s Jr. Cheeseburger costs $2.49 and has 270 calories, while Jack’s Jr. Jumbo Jack has 400 calories and 700 mg of sodium.

The chicken duel: Classic vs Cluck

Chicken is where Wendy’s pulls ahead. Wendy’s Classic Chicken Sandwich has 550 calories and costs $6.49, while Jack in the Box’s The Cluck has 710 calories, with its price TBC: a 160-calorie gap in Wendy’s favour. Sodium is almost a dead heat, at 1,630 mg for the Classic against 1,610 mg for The Cluck. The spicy duel tells the same story: Wendy’s Spicy Chicken Sandwich costs $6.49 and has 560 calories, while Jack’s Spicy Chicken Sandwich has 690 calories and 1,360 mg of sodium.

One nuance matters. Jack in the Box’s regular Chicken Sandwich, not The Cluck, has 560 calories and only 940 mg of sodium: almost the same calories as Wendy’s Classic, with 690 mg less sodium. Choose the regular sandwich at Jack in the Box if sodium is your concern, and the Classic at Wendy’s if calories and a published price are your concern.

Sides and snack attack: curly fries, tacos and egg rolls

Sides are where Jack in the Box runs away with it. Wendy’s sides are good and focused: Natural-Cut Fries, priced at $1.49-$4.39, and chicken nuggets. Jack in the Box offers fries, seasoned curly fries, onion rings, tacos, tiny tacos, egg rolls and stuffed jalapenos, all in the same menu. If your ideal order is a burger plus a taco plus an egg roll, only Jack in the Box can do it.

Look at the fries. A medium order of Jack’s regular fries has 430 calories and 780 mg of sodium, and a medium order of its seasoned curly fries has exactly the same 430 calories, but 940 mg of sodium: the curly version is saltier, not heavier. Two regular tacos have 340 calories and 720 mg of sodium, and one egg roll has 210 calories and 490 mg of sodium. These are items Wendy’s simply does not sell.

Breakfast showdown

Breakfast is Wendy’s clearest win on clarity, and Jack in the Box’s win on range. Wendy’s serves breakfast from 6:30 to 10:30 AM, a window this site covers on its Wendy’s breakfast hours page. Jack in the Box has a wide breakfast menu, from breakfast sandwiches and burritos to French toast sticks and pancakes, but its breakfast hours are marked TBC here because they were not verified for this post, and they vary by location.

The breakfast numbers are closer than many people expect. Jack’s Ultimate Breakfast Sandwich has 510 calories, 120 fewer than Wendy’s Breakfast Baconator at 630 calories and $4.99, and the Bacon Breakfast Jack is lighter still, at 380 calories and 850 mg of sodium. Jack’s Loaded Breakfast Sandwich, at 690 calories and 1,620 mg of sodium, is the heaviest breakfast here, and its hash brown, at 190 calories and 350 mg of sodium, is a useful light add-on.

Something sweet: Frosty vs shakes

Dessert is a clear Wendy’s win on price, and a Jack in the Box win on range. The Classic Frosty costs $1.79-$3.79 and has 190-510 calories: a cheap, light finish to a meal. Jack in the Box has a full shake menu in chocolate, vanilla, strawberry and OREO, in 16 oz and 24 oz sizes, and the 16 oz versions alone run from 580 to 690 calories.

If you want something sweet for under four dollars, Wendy’s is the answer. If you want a thick shake, Jack in the Box has the wider menu, and the 24 oz chocolate shake, at 970 calories, is almost a meal on its own.

Value, deals and everyday prices

Value is where Wendy’s is strongest: its value prices are published, clear and bundled. The Biggie Deals run at $4, $6 and $8, and the $5 Biggie Bag is also current. The deals on this site cover those bundles in full, and Wendy’s Rewards adds 10 points per $1, with a 200-point bonus for new members.

Jack in the Box does have value in its menu, but it is harder to price. Its Munchie Meals bundle a sandwich, tacos, curly fries and a drink, but with prices TBC you cannot compare them dollar for dollar with Wendy’s Biggie Deals. If you are ordering at Jack in the Box, check the app and the menu board at your local restaurant, because prices vary by location.

Who should choose which?

Choose Wendy’s if you want a burger or a chicken sandwich with a published price, a value bundle for $4, $5, $6 or $8, a Frosty for dessert, or breakfast before 10:30 AM. It is the better choice for a planned, everyday meal and for a family order. The Wendy’s vs McDonald’s and Wendy’s vs Burger King comparisons on this site use the same method, so you can compare all three on the same terms.

Choose Jack in the Box if you want a Jumbo Jack for fewer calories and less sodium than Dave’s Single, curly fries instead of regular fries, tacos or egg rolls with your burger, a wider breakfast menu, or a thick shake instead of a Frosty. It is the better choice for a snack-heavy order and for a group where everyone wants something different.

Conclusion

Wendy’s wins this matchup for most people, most of the time, on the things that matter every day: price transparency, value bundles, chicken and dessert. The Classic Chicken Sandwich beats The Cluck by 160 calories, the Biggie Deals and the $5 Biggie Bag make a cheap meal easy to find, and the Frosty costs $1.79-$3.79.

Jack in the Box wins the other half, and it is a real win. The Jumbo Jack is lighter and much lower in sodium than Dave’s Single, the regular Chicken Sandwich is much lower in sodium than Wendy’s Classic, and the menu is wider in a way Wendy’s cannot match. For a burger, chicken and value run, go to Wendy’s. For a wider menu, a lighter flagship burger and a snack-heavy bag, go to Jack in the Box.
