Calorie Deficit Calculator

Estimate maintenance calories first, then compare practical deficit scenarios.

Quick plan

  • Start with your maintenance estimate.
  • Compare smaller and larger calorie deficits.
  • Use the result to plan your next nutrition target.

Best next step

  • Use the calculator: open the tool, change the inputs, and save your best scenario.
  • Compare versions: supported tools can keep up to three scenarios on this device.
  • Keep context: saved results appear in My Calcoras for later.
