How to use this calculator

  • Enter your average daily calories.
  • Enter target daily calories.
  • Enter number of days in the month.
  • Add cheat days if you want to estimate their influence.

What the result means

The result shows cumulative monthly calorie surplus or deficit, which is usually more important than one isolated high-calorie day.

Monthly intake = daily calories × month length. Calorie gap = intake - target. Estimated weight impact = calorie gap ÷ 7,700.

The 7,700 kcal per kg estimate is approximate and individual weight change varies.

Example calculation

Eating 2,300 kcal against a 2,100 kcal target for 30 days creates a 6,000 kcal surplus, about 0.78 kg estimated impact.

Tips for better results

  • Manage monthly totals, not just single days.
  • Divide surplus by remaining days for correction.
  • Keep deficits sustainable.
  • Use cheat days inside the monthly budget.
