Jack in the Box Jumbo Jack: Calories, Price, Ingredients (2026)

The wording quoted by menujackinthebox.com and PriceListo is: “100% beef seasoned as it grills, lettuce, tomato, pickles, onions, ketchup & mayo on a buttery bakery bun. *Jumbo isn't one of those ironic nicknames.” One of them lists the parts as split top bun, large patty, lettuce, tomato, sliced onions, pickles, ketchup, mayo, and butter. We could not open the brand's own Jumbo Jack page, so this is a quoted description, not something we confirmed at the source. The brand's ingredient PDF lists components alphabetically and does not say which belong to which burger.

By the brand's 2026 nutrition PDF: Jumbo Jack 520, Jumbo Jack Cheeseburger 600, Jr. Jumbo Jack 400, Jr. Jumbo Jack Cheeseburger 440 and Double Jack 830. The Jumbo Jack is 26% of a 2,000-calorie day, a reference figure from US labels and not a target for you.

23 g of protein, 33 g of total fat (10 g saturated) and 700 mg of sodium, which is 30% of the FDA Daily Value of 2,300 mg, in a 216 g serving. That is 4.4 g of protein per 100 calories. Among the 15 burgers on this site it ranks #10 for protein (1 is most) and #2 for sodium (1 is lowest).

Our estimate is $5.69 for app pickup, from 2,067 restaurants as of November 11, 2026, with a range of $3.99–$7.99. Outside pages show anything from $3.69 to $7.50 for the same burger because they cover different dates, places and ordering channels, and 2 of them show no date at all. Price varies by location, so treat ours as an estimate.

Among the 15 states with at least 10 restaurants in the sample, Utah has the lowest typical price ($4.29) and Hawaii the highest ($7.69), a gap of $3.40 or 79%. California has the most restaurants sampled (914) at a typical $5.99. These are Drive Thru Index's figures as of November 11, 2026.

On our estimates, two Jr. Jumbo Jacks cost $5.78 against $5.69 for one Jumbo Jack, $0.09 more. You would get 800 calories and 28 g of protein against 520 and 23 g, plus 1,400 mg of sodium against 700 mg. Prices differ by restaurant, so check yours.

80. The Jumbo Jack Cheeseburger is 600 calories against 520, and the brand's American Cheese row is 40 calories a slice, so the Cheeseburger carries 2 slices. The weights agree: 22 g more, and 2 slices of 11 g is 22 g. On the Jr. version, one slice adds 40.

The brand's nutrition PDF and its allergen guide both list milk, egg, wheat, soy, and sesame for the Jumbo Jack. When we matched the ingredient statements for the bun, patty, seasoning, vegetables, ketchup and mayonnaise, egg, wheat, soy, and sesame trace back to a component and milk does not. The PDF does not say which part carries it, so we cannot tell you. If milk matters to you, ask the restaurant. This is a gap in what the brand publishes, not a finding about the food.

The brand lists sesame as an allergen for the Jumbo Jack and notes that buns may contain sesame. The brand's split top bun statement is printed in 2 versions, and one lists sesame flour and the other does not, which fits a regional difference. The PDF does not say which version your restaurant uses, so treat sesame as present.

The brand's PDFs publish a weight for the whole burger, 216 g for the Jumbo Jack, and none for the patty, so we cannot check it. The only support we found is a 1988 quote from a company executive, set out in the history section. It is the company's own claim, not a figure the brand publishes now.

The description quoted above lists ketchup and mayo and no Secret Sauce. The brand sells a separate Secret Sauce (1 packet) row at 30 calories. One fan wiki says the burger once came with it. Anyone can edit that wiki and no primary source confirms it, so we left it out of the history.

It launched in 1971, according to QSR Magazine and Hatch Magazine, and the trademark record gives a first-use date in the same year. The history section shows each source and its date.

We searched the ingredient statements we matched to the burger. High fructose corn syrup appears in the bun and ketchup statements, though the bun statement says “or sugar” and the other printed bun version lists only sugar. Yellow 5, a color, appears in the pickles statement. The PDF does not map components to menu items, so this is a match on the burger's description, not a brand statement about the burger.

The brand has no row for the deal. Two Jumbo Jack rows add up to 1,040 calories. JackBoxMenus reports 1,040, while JackInBoxUSA reports 1,140, which the brand's rows do not support. The deal's price and availability are reports from other sites (2 sites) and vary by restaurant.

At one Woodburn, OR restaurant, PriceListo lists the burger at $7.50 and shows delivery totals with fees of $11.18 on DoorDash, $12.65 on Uber Eats, and $13.34 on GrubHub, which is 49% to 78% more. That is one restaurant on one page dated October 24, 2026, so use it as an example of the gap, not a rule.

By the brand's own add-on rows: American cheese 40 per slice, ketchup (0.57 oz.) 20, mayonnaise (0.25 oz.) 80, mustard (0.19 oz.) 5 and Creamy Bacon Mayo (0.68 oz.) 120. The brand publishes no row for bacon slices, so we cannot give a figure for adding bacon. The builder above adds these rows to any burger in the family.
