Nutrition Facts per Big Mac
McDonald's US menu nutrition
This page covers standard United States menu items. McDonald's states that nutrition values are based on standard product formulations and serving sizes; preparation, customization, suppliers, and local availability can change the final values.
| US menu item | Calories | Primary source |
|---|---|---|
| Big Mac | 580 kcal | McDonald's US product page |
| Egg McMuffin | 310 kcal | McDonald's US product page |
| Filet-O-Fish | 380 kcal | McDonald's US product page |
How to use these numbers
Check the product page for the exact item and use the restaurant or app nutrition details after any customization. A meal total depends on the selected side, drink, sauces, and portion size, so this page does not assign a single value to every “Big Mac meal.”
Calorie counts describe energy, not whether a food is “good” or “bad.” For sodium, saturated fat, allergens, and ingredients, use the current McDonald's listing for the exact product.
Frequently asked questions
Is this data valid outside the United States?
No. Recipes, serving sizes, and menus vary by country. Use the local McDonald's website for another market.
Does changing an ingredient change the total?
Yes. Removing or adding cheese, sauce, meat, or bread changes the nutrition profile. Treat the listed number as the standard US product, not a customized order.
