Jack in the Box vs McDonald’s: Which Is Healthier?
Jack in the Box is the late-night chain and McDonald’s is the everywhere chain, and people compare them because the menus overlap: a signature burger, a crispy chicken sandwich, fries, tacos on one side. We put Jack in the Box’s official 2025 nutrition table next to McDonald’s current figures for the matching orders.
Key takeaways
- Jack in the Box lists the Jumbo Jack at 520 calories and 700 mg sodium; McDonald’s lists the Big Mac at 580. On the plain signature burger, Jack in the Box is lighter.
- The rest of the Jack in the Box burger menu is heavier: Jumbo Jack Cheeseburger 600, Sourdough Jack 690 (1,300 mg), Ultimate Cheeseburger 840 (1,550 mg).
- Chicken reverses the result: McDonald’s McCrispy is 470 calories; Jack’s Spicy Chicken is 690 (1,360 mg) and the Cluck Sandwich 710 (1,610 mg).
- Fries are a wash (430 at Jack in the Box for a medium, curly or regular), so the meal gap comes from the sandwich you pick.

Signature burger: Jack in the Box wins by 60 calories
Jack in the Box’s 2025 nutrition table lists the Jumbo Jack at 520 calories, 33 g of fat, 10 g saturated and 700 mg of sodium. McDonald’s lists the Big Mac at 580 calories. That 60-calorie gap is real but small, and the Jumbo Jack’s sodium figure is the more interesting number: 700 mg is low for a fast food burger, roughly half of what most chicken sandwiches on either menu carry. Add cheese and the Jumbo Jack Cheeseburger goes to 600 calories and 1,110 mg, which erases the advantage.
The rest of the burger menu is where Jack in the Box gets heavy
The Sourdough Jack, the chain’s other signature, is 690 calories and 1,300 mg of sodium. The Ultimate Cheeseburger is 840 calories with 23 g of saturated fat and 1,550 mg of sodium, more than a Big Mac and a McCrispy combined in saturated fat. If you order by craving rather than by calorie, Jack in the Box offers more ways to land above 700 calories than McDonald’s does.
Chicken: McDonald’s wins clearly
McDonald’s lists the McCrispy at 470 calories. Jack’s Spicy Chicken Sandwich is 690 calories and 1,360 mg of sodium; the Cluck Sandwich is 710 and 1,610 mg. That is a 220 to 240 calorie gap on the same kind of item, and the largest difference in this comparison. If chicken is your order, this one is not close.
Fries and the meal
Jack in the Box lists a medium order of fries at 430 calories whether curly (940 mg sodium) or regular (780 mg). McDonald’s lists a Big Mac Meal with medium fries and a medium Coke at 1,170 calories and a McCrispy Meal at 1,040. A Jumbo Jack with medium fries and a similar drink lands in the same neighbourhood, so the meal does not separate the chains; the sandwich does.
The tacos, briefly
Jack in the Box’s two tacos are 340 calories and 720 mg of sodium, the lightest named item on either list, and the thing people order at 1 AM. McDonald’s has no equivalent. If you are choosing Jack in the Box, the tacos and the plain Jumbo Jack are the two orders where it comes out ahead. We compare them with Taco Bell’s tacos in Jack in the Box vs Taco Bell.
When the bigger goal is eating less fast food
The honest summary is that the chains are close on their lightest items and far apart on their heaviest, which means the decision is made by what you order, not where. If you keep ending up at the drive-thru at midnight, the useful question is what gets you there, not whether the Jumbo Jack beats the Big Mac by 60 calories.
