Desk worker
A 30-year-old man weighs 70 kg, is 175 cm tall, and is sedentary.
Resting calories are about 1,649 kcal/day and maintenance is about 1,979 kcal/day.
A sedentary activity level keeps the total close to the resting estimate.
Use this when you want a practical estimate of resting calories, maintenance calories, and a starting point for cutting or gaining.
Inputs
Estimate adult calorie needs with a simple TDEE calculator and compare several common equations.
Results
See your resting calories, TDEE, and calorie targets side by side.
Equation used
This calculator is an estimate for adults. It may not be appropriate for pregnancy, breastfeeding, competitive athletes, or people with metabolic conditions.
BMR / REE estimate before activity.
TDEE after applying activity level.
TDEE minus 300 kcal/day.
TDEE minus 500 kcal/day.
TDEE plus 250 kcal/day.
Quick take
Use this when you want a practical estimate of resting calories, maintenance calories, and a starting point for cutting or gaining.

Formula
TDEE formula
Choose a resting-calorie equation, then TDEE = BMR x activity multiplier.
This is an estimate for adults, not a medical prescription. Real energy needs can vary with age, body composition, and health status.
Examples
Desk worker
A 30-year-old man weighs 70 kg, is 175 cm tall, and is sedentary.
Resting calories are about 1,649 kcal/day and maintenance is about 1,979 kcal/day.
A sedentary activity level keeps the total close to the resting estimate.
Active routine
A 28-year-old woman weighs 60 kg, is 165 cm tall, and is moderately active.
Resting calories are about 1,330 kcal/day and maintenance is about 2,062 kcal/day.
The activity multiplier increases daily needs after the resting estimate.
Gaining phase
A 35-year-old man weighs 82 kg, is 180 cm tall, and is very active.
Resting calories are about 1,775 kcal/day and the gain target is about 3,312 kcal/day.
This gives a simple calorie surplus starting point for a higher-energy phase.
When to use
Use it when planning a calorie target for maintenance, gradual fat loss, or moderate weight gain.
Common mistakes
FAQ
Why is this only an estimate?
Activity, body composition, and health status all affect calorie needs, so the result is a practical starting point rather than a guarantee.
Can I use this for children or pregnancy?
No. This calculator is for adults only and may not be appropriate for pregnancy, breastfeeding, athletes, or people with metabolic conditions.
Next step
Want to turn this estimate into a plan?
A registered dietitian or clinician can help turn calorie targets into a nutrition plan that fits your goals and health needs.
Recheck calories if your age, weight, activity, or goal changes.
