Your selected level is the headline result; the other rows show how much the category choice alone moves the estimate.
Bars are scaled to the extremely-active value for your BMR. All values are kcal/day.
TDEE = Mifflin–St Jeor BMR × activity factor, where BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5 for men or − 161 for women. Activity factors used here: 1.2 sedentary, 1.375 lightly active, 1.55 moderately active, 1.725 very active, 1.9 extremely active.
Weight 65 kg, height 170 cm, age 30, female, lightly active (1.375): BMR = 10 × 65 + 6.25 × 170 − 5 × 30 − 161 = 1,401.5 kcal/day. TDEE = 1,401.5 × 1.375 = 1,927.1 kcal/day, or 13,490 kcal per week, of which 525.6 kcal/day is the activity increment above BMR. At the sedentary factor the same BMR gives 1,681.8 kcal/day; at extremely active it gives 2,662.9 kcal/day. Use Reset example above to reproduce this result.
TDEE inherits the limits of both parts: BMR is a population equation that varies between individuals, and the activity factor is a coarse category chosen by judgment, not a measurement of actual days. Two people picking the same label can have quite different true activity, and day-to-day variation is averaged away. The result is a planning estimate, not a measured daily burn.
BMR is resting expenditure only. TDEE multiplies BMR by an activity factor to include everything else a day involves.
Judge a typical week honestly: mostly sitting is sedentary, light daily movement is lightly active, regular training is moderately active, hard daily training is very active. When in doubt, the lower category is the more cautious estimate.
Because the factor multiplies the whole BMR: moving from 1.2 to 1.9 raises the example result by about 58%, so a wrong category is the largest error source on this page.
No. It is an estimate of expenditure, not a recommendation for intake. Intake decisions involve goals and circumstances this page does not model.
No. This calculation runs locally in your browser and the values you enter are not sent to a CalcMintly database.
Yes — weight, age, and activity all feed the equation, so re-entering current values gives a current estimate.
