Subway Calorie Calculator
This Subway calorie calculator (also useful to calculate Subway nutrition for any sub calorie count you’re curious about) lets you build a sandwich from bread, protein, cheese, vegetables, and sauce, and see estimated calories, protein, carbs, fat, and sodium update instantly. Use it to compare orders before you build the real thing.
Also known as: Subway nutrition calculator, Subway sub calorie calculator, Subway calories calculator, calories in Subway calculator, Subway sandwich builder calculator, Subway macro calculator.
Calories in a Subway sub come from five stacked layers: bread (roughly 180–290 kcal for 6″), protein (0–220 kcal), cheese (0–50 kcal), vegetables (nearly 0), and sauce (5–110 kcal). Add them up and double everything for a Footlong. Sauce and cheese usually swing the total more than protein choice does.

Why Use a Subway Calorie Calculator Before You Order
A Subway order isn’t one nutrition line — it’s five separate choices layered together: bread, protein, cheese, vegetables, and sauce. A Subway calorie calculator adds those layers up in real time as you build, so you can see the effect of swapping a sauce or upsizing before you’re standing at the counter.
Sauce is usually where the biggest swing hides. A single serving of mayonnaise adds roughly 110 calories, while mustard or red wine vinegar adds closer to 5 — the sauce alone can be worth over 100 calories in either direction, often more than the protein choice itself. Vegetables, by contrast, are nearly free calorically, which is why loading up on veggies is one of the easiest ways to add volume and fiber without meaningfully changing the total.
This tool also works as a way to calculate Subway nutrition for tracking macros, or a sandwich builder for comparing a few order combinations side by side before committing to one. Switching from 6-inch to Footlong doubles every value, since a Footlong uses double the bread, protein, cheese, and sauce of the same recipe.
How This Subway Calories Calculator Adds It Up
A Subway order is really five separate nutrition profiles stacked together — bread, protein, cheese, vegetables, and sauce — each contributing its own calories, protein, carbs, fat, and sodium to the final total.
Bread sets the floor
Even before any filling, 6″ bread alone typically runs from about 180 to 290 calories, with wraps and cheese-baked breads landing at the higher end of that range.
Vegetables are nearly free
Most standard vegetable toppings add 0 to 5 calories each, which is why loading up on veggies is one of the easiest ways to add volume without meaningfully changing the calorie total.
Sauce is the biggest swing
A single serving of mayonnaise adds roughly 110 calories, while mustard or vinegar adds closer to 5 — the sauce choice alone can be worth over 100 calories either direction.
Footlong doubles everything
A Footlong uses double the bread, protein, cheese, and sauce of a 6″ sub on the same recipe, so every number in the calculator simply doubles when you switch sizes.
Subway Calorie Calculator: Worked Examples
Three common order builds worked end-to-end using the same estimates as the calculator above.
Lower-calorie build: Veggie Delite, wheat, mustard
A 6″ Veggie Delite on 9-Grain Wheat with no cheese, all standard veggies, and yellow mustard. What’s the estimated total?
Given inputs
- Bread: 9-Grain Wheat
- Protein: Veggie Delite (none)
- Sauce: Yellow Mustard
Computed outputs
- Calories: ≈ 200 kcal
- Protein: ≈ 9 g
- Sodium: ≈ 285 mg (low share of daily limit)
Balanced build: Grilled chicken Footlong, provolone, ranch
A Footlong Grilled Chicken on Hearty Italian with provolone, standard veggies, and ranch dressing.
Given inputs
- Size: Footlong (×2)
- Bread: Hearty Italian
- Protein / cheese / sauce: Grilled Chicken / Provolone / Ranch
Computed outputs
- Calories: ≈ 940 kcal
- Protein: ≈ 53 g
- Sodium: ≈ 1,780 mg (a large share of a daily limit)
High-sodium build: Italian B.M.T. Footlong, double cheese
A Footlong Italian B.M.T. on Italian Herbs and Cheese bread with double American cheese, olives, and oil blend — where does the sodium land?
Given inputs
- Size: Footlong (×2)
- Protein: Italian B.M.T.
- Extras: Double cheese
Computed outputs
- Calories: ≈ 1,300+ kcal
- Sodium: well over 2,000 mg
- Calculator flags this as a large share of a typical daily sodium limit
Subway Calorie Calculator Mistakes to Avoid
Forgetting the sauce is often the biggest single item
It’s easy to focus on protein and cheese while treating sauce as an afterthought, but a heavy sauce like mayonnaise or ranch can rival or exceed the calorie contribution of the protein itself.
Assuming vegetables meaningfully change the calorie total
Toggling vegetables on or off barely moves the calorie count, since most add 0–5 calories each. Don’t skip vegetables to “save calories” — the sauce and cheese choices matter far more.
Overlooking sodium while watching calories
A sandwich can look moderate on calories while still carrying a large share of a daily sodium budget, since cured meats, cheese, and many sauces are sodium-dense independent of their calorie content.
Treating these figures as official, restaurant-verified numbers
These are estimates from published and third-party nutrition sources, not a live feed from Subway. Recipes, portion sizes, and regional menus change — check subway.com/nutrition for an exact, current figure.
Forgetting Footlong doubles everything, not just calories
Switching to Footlong doubles protein, carbs, fat, and sodium along with calories — it’s not just a bigger sandwich calorically, it’s a proportionally bigger sodium and fat load too.
