Basal metabolic rate (BMR) estimates calories your body burns at rest before activity. Use it to set maintenance targets or plan a safe deficit with a dietitian.
Calculate percentage-based amounts for bmr calculator scenarios.
Enter sex, age, weight, and height. We apply Mifflin–St Jeor (default) or Harris–Benedict, then show daily BMR and optional TDEE multipliers you select.
Mifflin–St Jeor: men BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5; women subtract 161 instead of adding 5.
A 35-year-old woman, 165 cm, 68 kg → BMR ≈ 1,430 kcal/day before activity factors.
Mixing up rate percent with the final total, or forgetting to include the base amount in totals.
Avoid these pitfalls: - Mixing gross and net values without converting units. - Copying results without checking whether inputs match your real scenario. - Assuming compound or tiered rules when this tool models a single straightforward formula.
Fast percentage math with shareable URL parameters and mobile-friendly inputs.
BMR models do not capture thyroid disorders, pregnancy, or high muscle mass extremes; treat output as a starting estimate.
Base amount: starting value. Rate percent: percentage applied to the base. BMR Calculator terms: - Input fields: values you control for the scenario. - Output fields: computed results derived from the formula. - Calculators context: typical assumptions for this category on CalcMage.
