Calculate calories, protein, carbs, and fat for any Subway sandwich. Customize bread, toppings, and sauces.
Subway Nutrition & Calorie Tracking
Subway is popular for offering healthier fast-food choices, but calories and macronutrients can vary significantly depending on your bread, protein, cheese, and sauce selections.
While a standard 6-inch turkey breast sandwich on wheat bread contains roughly 280 calories, adding cheese, mayonnaise, and choosing Italian herbs & cheese bread can easily double the caloric density.
This calculator allows you to build your custom sandwich, select toppings, and view the total calories, protein, carbohydrates, and fats instantly to keep your meal aligned with your diet.
