µ Calorie Deficit Calculator
How It Works
Estimate a daily calorie target from maintenance calories and a chosen deficit. Use Calorie Deficit Calculator as a general estimate from the measurements and assumptions you enter.
The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: Target Calories = Maintenance Calories − Deficit. Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.
Understanding Calorie Deficit
Calorie Deficit is a general health or fitness estimate based on the measurements and assumptions requested by the calculator.
Keep in mind: Health estimates are not diagnoses and can differ from an individual's actual needs or measurements. Review the calorie deficit inputs and units before relying on the result.
When to Use This Calculator
Use Calorie Deficit Calculator as a general estimate from the measurements and assumptions you enter.
Practical tip: For this Calorie Deficit Calculator, use the result as a starting estimate and change one measurement or activity assumption at a time so you can see how sensitive the estimate is.
Formula
Target Calories = Maintenance Calories − Deficit
Example
At 2,500 maintenance calories and a 500-calorie deficit, the target is 2,000 kcal/day.
