ⓘ For adults 18+. General estimates only—not a personal nutrition plan or medical advice. Not intended for pregnancy, breastfeeding, or clinical needs.
Resting energy × activity+
Male REE = 10 × kg + 6.25 × cm − 5 × age + 5
Female REE = 10 × kg + 6.25 × cm − 5 × age − 161
TDEE = estimated REE × selected activity factorThese are the simplified Mifflin–St Jeor equations for resting energy expenditure (REE), often loosely called BMR in calculators. [1] Read the original paper ↗
The activity multipliers in this tool (1.20–1.90) are rough planning assumptions, not measured expenditure or part of the original REE equation. Your actual needs can differ. Reference sex chooses the equation coefficient; it is not a judgment of gender identity.
Supported inputs: adults 18–100, 30–300 kg, and 120–230 cm. These are software limits, not a guarantee the model fits every person in that range.
