$8.98 buys four patties and four cheese slices; the bacon route runs $7.98 to $8.78.
A Burger King Quad Stacker was a real product, sold from 2006 and briefly again in 2023, and it is not on the menu now. Rebuilding it means four patties, four slices of cheese, bacon and Stacker Sauce. Two Double Cheeseburgers at $4.49 each cover the beef and the cheese for $8.98 and 800 calories. Bacon and the sauce carry no published charge, so the finished sandwich cannot be totalled.

How it works
Ask for a quad bacon cheeseburger, in those words
Component wording beats a product name that left the menu years ago. No pickles, no ketchup, no mustard, then Stacker Sauce added, is the sequence a till can follow.
Take the two-sandwich route if the counter says no
A pair of Double Cheeseburgers at $4.49 each gives four patties and four cheese slices for $8.98. Stacking them yourself asks nothing of the kitchen.
Use the bacon version to save money
Buying two Bacon Double Cheeseburgers lands between $7.98 and $8.78 and brings the bacon along. That is cheaper than the plain route at both ends of the band.
Ask whether Stacker Sauce is still carried
It went off the menu with the sandwich and restaurants differ on whether any is left in the building. Nothing published gives it a price.
Compare against the listed big burger first
A Bacon King was recorded at $10.49 or $11.19 for two patties with bacon. Against $8.98 for four patties, the custom route wins on beef and loses on convenience.
If something goes wrong
Nobody had heard of a Quad Stacker
- Cause
- It left the menu after a brief return in 2023 and crew turn over quickly
- Fix
- Describe it instead. A quad bacon cheeseburger with no pickles, ketchup or mustard is a request built from modifiers the till already has.
There is no Stacker Sauce left
- Cause
- The sauce went with the sandwich and stock varies restaurant by restaurant
- Fix
- Ask what sauces are available and pick one. Nothing published prices Stacker Sauce, so even where it exists the charge is a local matter.
The till would not go past a double
- Cause
- Patty modifiers are configured centrally and often cap low
- Fix
- Buy two sandwiches and stack them. A pair of Double Cheeseburgers reaches four patties for $8.98 without needing a modifier at all.
The bacon route cost more than expected
- Cause
- That sandwich has no settled price, with readings at $3.99 and at $4.39
- Fix
- Expect anywhere from $7.98 to $8.78 for the pair. Both ends of that band still undercut the plain two-sandwich route.
A listed burger looked like better value
- Cause
- Big listed burgers carry bundle pricing that custom stacks never do
- Fix
- Check the Big King at $6.99 and the Bacon King at $10.49 or $11.19 before committing. Neither has a published calorie count, which is its own problem.
The calorie total does not match other pages
- Cause
- Every figure here comes from adding listed sandwiches rather than from a company count for the build
- Fix
- Use 800 for the plain route and 880 for the bacon one. No Burger King count covers a four-patty custom sandwich.
What’s fixed, and what actually varies
Retired products behave differently from invented ones. This is a retired product, which means the ingredients are all still in the building.
Fixed
- The Quad Stacker was a genuine Burger King product with a recipe
- It ran from 2006, returned briefly in 2023 and left again
- Four patties and four cheese slices come to $8.98 from two Double Cheeseburgers
- No published US listing carries a price for Stacker Sauce
- No restaurant is obliged to assemble a four-patty sandwich
Varies
- The Bacon Double Cheeseburger, recorded at $3.99 and at $4.39 with no middle
- Whether Stacker Sauce is still stocked at your restaurant
- Whether the till carries a quad modifier or caps at a double
- Whether a franchisee will run four patties during a rush
- What bacon costs when added separately, which nothing publishes
Open a Double Cheeseburger in the Burger King app with your restaurant selected and see how far the patty modifier goes. Where it stops at a double, two sandwiches is the answer and the app gives you the total before you leave. Sauce is the part the app rarely settles, so that question belongs at the counter.
Rebuilding a retired sandwich from what is still on the board
Every list of this kind muddles two categories. A retired product has a recipe, and every ingredient it used is still being delivered to the restaurant on the same lorry as everything else, which is the whole reason a customer can put one back together years after the till stopped recognising the name. An invented name has neither. This one sits firmly in the first category.
What it was is not in dispute: four beef patties, four slices of cheese, bacon and Stacker Sauce, sold from 2006 and back for a short spell in 2023. Reaching four patties today takes two sandwiches. Two Double Cheeseburgers at $4.49 each come to $8.98 and 800 calories, and the cheese count works out at four without asking for anything extra.
The better route is slightly awkward to quote. A Bacon Double Cheeseburger was recorded twice, at $3.99 and at $4.39, and two numbers that far apart have no honest middle, so its own page prints no typical figure. Buying two puts the pair somewhere between $7.98 and $8.78 for 880 calories, bacon included. Both ends of that band beat the plain route.
One component stops any of this being a finished total. Stacker Sauce has no published price in any US listing checked, and it is the ingredient most likely to have left the building along with the sandwich. Bacon added separately is unpriced too. Nobody publishes either figure.
For comparison, a Bacon King was recorded at $10.49 or $11.19 with two patties, and a Big King at $6.99. Neither carries a company calorie count. The same stack circulates under a cruder nickname, the Suicide Burger, which is a customer word rather than anything Burger King printed. Restaurant Brands International franchises almost the whole estate, so whether a kitchen will run four patties at once is decided where you are standing.
Questions people ask
Is the Quad Stacker still sold?
No. It ran from 2006, came back briefly in 2023 and went again. What remains is a recipe whose ingredients are all still stocked.
How much does it cost to rebuild?
$8.98 for four patties and four cheese slices, from two Double Cheeseburgers at $4.49 each. Adding bacon and Stacker Sauce moves it by an amount nobody publishes.
Is there a cheaper route?
Two Bacon Double Cheeseburgers land between $7.98 and $8.78 and include the bacon. That sandwich has no settled price, which is why the answer is a band.
How do I ask for it?
By components: a quad bacon cheeseburger with no pickles, ketchup or mustard, then Stacker Sauce added. The name itself has been off the menu for years.
What is the Suicide Burger?
A customer nickname for roughly the same stack. Burger King never sold anything under that name, and the sandwich it describes is the Quad Stacker.
How many calories is it?
800 by the plain route and 880 with bacon, adding company counts for the listed sandwiches. No count exists for the finished build.
Where do these prices come from?
Published US listings checked on 19 August 2026, since Burger King issues no US prices. The calorie figures are the company's, dated November 2022.
