A standard McDonald’s Big Mac in the U.S. has about 580–590 calories (roughly 2,400 kJ).

Quick Scoop

  • Big Mac alone: about 580–590 kcal.
  • This is roughly 25–30% of a typical 2,000 kcal daily intake for an adult.
  • Nutrients per burger are around:
    • Fat: about 30–34 g
    • Carbs: about 45 g
    • Protein: about 25 g

Think of it as a quarter to a third of your daily energy budget in one sandwich, before fries or a drink.

If you want, I can also break down how that changes when you add fries and soda or compare it to other burgers.
