Estimate total daily energy expenditure from BMR and activity assumptions.
Quick planning, rough comparisons, and checking whether your assumptions are in the right range before you rely on final quotes or advice.
Review the assumptions below, then compare with related calculators if your decision depends on rates, eligibility, or provider-specific rules.
How this calculator works
- Basal metabolic rate is estimated with the Mifflin-St Jeor equation.
- Activity multipliers convert BMR into maintenance calories.
- The result is your estimated maintenance energy expenditure.
Worked example
A moderately active 30-year-old at 170 cm and 70 kg lands near the mid-2000 calorie range for maintenance.
Important assumptions
- This is an estimate based on population formulas.
- Actual maintenance calories vary with muscle mass, routine, and metabolism.
- Weight change targets should be adjusted gradually in practice.
