Calorie Deficit Calculator for Weight Loss | BiteBud
Estimate your daily maintenance calories, then see a moderate starting range below maintenance. Enter your details to get an educational estimate for planning weight loss. Your needs can differ from the calculator, so treat the result as a flexible starting point rather than a fixed prescription.
This free tool provides general educational estimates and is not medical advice. Results can vary based on your body, health, goals, and actual food portions.
How this calorie deficit calculator works
The estimate uses the weight, height, age, and sex selection you enter to estimate resting energy needs, then adjusts that estimate using your selected activity level. The result is an approximation of maintenance calories, not a measurement of your metabolism.
Understanding the suggested calorie range
This calculator shows a range at 80–90% of its estimated maintenance value, equivalent to a 10–20% starting deficit. It is a general planning example, not a guaranteed rate of weight loss or a personalized medical recommendation. Real energy needs and weight trends vary, so use your experience over time and seek guidance from a qualified health professional when appropriate.
