TDEE Calculator
Calculate basal metabolic rate and multiply it by the activity level that matches your lifestyle to see a realistic total daily energy expenditure (TDEE).
Estimate total daily energy expenditure (TDEE) with Mifflin-St Jeor BMR plus precise activity multipliers.
Sedentary (desk job)
×1.200 BMR
1,629 kcal
Little or no deliberate exercise each week.
Light (1–3 sessions/week)
×1.375 BMR
1,867 kcal
Casual walks, yoga, or light strength work a few times a week.
Moderate (3–5 sessions/week)
×1.550 BMR
2,105 kcal
Consistent training or active job plus structured workouts.
Active (6–7 sessions/week)
×1.725 BMR
2,342 kcal
Daily training, field work, or labor-intense job duties.
Athlete (2× per day)
×1.900 BMR
2,580 kcal
Competitive athletics or physically demanding occupations.
BMR × activity factor
BMR = 10w + 6.25h − 5a + s TDEE = BMR × activity_factor
Weight (w) is kilograms, height (h) is centimeters, age (a) is years, and s equals +5 for males or −161 for females. Activity factors range from 1.2 (sedentary) to 1.9 (two-a-day athletes).
How to use
- Select gender and enter age, weight, and height.
- Pick the activity level that mirrors your weekly training or job.
- Review the BMR, resulting TDEE, weekly burn, and the comparison cards for every multiplier.
Example
Input: Female, 29 years, 62 kg, 167 cm, Activity = Moderate
Output: BMR ≈ 1,358 kcal, TDEE ≈ 2,105 kcal/day, Weekly burn ≈ 14,735 kcal

Deep dive & study plan
TDEE Calculator: Total daily energy expenditure from Mifflin-St Jeor BMR and activity multipliers. It's built around tdee, maintenance calories, activity multiplier, so you can go from a raw question to a checked answer without switching tools.
The math behind it: Weight (w) is kilograms, height (h) is centimeters, age (a) is years, and s equals +5 for males or −161 for females. Activity factors range from 1.2 (sedentary) to 1.9 (two-a-day athletes). The core relationship is BMR = 10w + 6.25h − 5a + s TDEE = BMR × activity_factor, shown above the calculator so you can see exactly how your inputs turn into the result.
To use it well: (1) Select gender and enter age, weight, and height. (2) Pick the activity level that mirrors your weekly training or job. (3) Review the BMR, resulting TDEE, weekly burn, and the comparison cards for every multiplier. Keep your units consistent as you go, and re-run a case you already know the answer to — it's the fastest way to catch a typo before it throws off a result you're relying on.
Worked example: entering Female, 29 years, 62 kg, 167 cm, Activity = Moderate returns BMR ≈ 1,358 kcal, TDEE ≈ 2,105 kcal/day, Weekly burn ≈ 14,735 kcal. Try swapping in your own numbers next, especially a case you're unsure about, before you use this for something that matters.
Quick retention checklist
- Speak the formula aloud (or annotate it) so the relationships stick.
- Write each step in your own words and compare with the numbered list above.
- Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
- Check at least one related calculator below — it's the fastest way to confirm your numbers still line up from a different angle.
FAQ & notes
How is TDEE different from BMR?
BMR is resting energy only. TDEE multiplies it by an activity factor so it reflects workouts, chores, and job demands.
What if I’m between two activity levels?
Start with the lower option, track progress for a couple of weeks, and adjust if your real-world maintenance differs.
What formula does the TDEE Calculator use?
Weight (w) is kilograms, height (h) is centimeters, age (a) is years, and s equals +5 for males or −161 for females. Activity factors range from 1.2 (sedentary) to 1.9 (two-a-day athletes).
How do I use the TDEE Calculator?
Select gender and enter age, weight, and height. Pick the activity level that mirrors your weekly training or job. Review the BMR, resulting TDEE, weekly burn, and the comparison cards for every multiplier.
