A classic Whataburger (the regular beef burger) has about 590 calories in one sandwich, without any custom add‑ons or a meal combo.

Quick Scoop

  • Regular Whataburger burger: about 590 calories per sandwich.
  • Those calories come mostly from fat and carbs , with a solid amount of protein.
  • Calorie counts can change with extras (cheese, bacon, sauces) or if you order a combo meal with fries and a drink.

If you’re tracking your intake, think of a plain Whataburger as a medium‑to‑high calorie main item, and expect a full meal with fries and a drink to land well above that 590‑calorie mark.
