Average Calories Burned Per Day: By Age, Sex & Activity Level

Updated July 2026 · 7 min read

The average person burns between 1,600 and 2,400 calories per day — but that range varies widely based on age, sex, body size, and how active you are. Below you'll find detailed tables, a breakdown of where those calories go, and how to calculate your personal number.

Average calories burned per day (adult women–men)

Average Calories Burned by Age and Sex

These estimates are based on the Mifflin-St Jeor equation with a "lightly active" multiplier (1.375), representing someone who walks 30 minutes most days but doesn't do structured exercise.

AgeMen (lightly active)Women (lightly active)
18–252,500–2,8002,000–2,200
26–352,400–2,6001,900–2,100
36–452,300–2,5001,800–2,000
46–552,200–2,4001,700–1,900
56–652,000–2,2001,600–1,800

Calories Burned by Activity Level

Your activity level has the biggest impact on total calories burned after body size. Here's what an average 155 lb (70 kg) woman and 180 lb (82 kg) man burn at each level:

Activity LevelMan (180 lb)Woman (155 lb)
Sedentary (desk job, no exercise)2,1001,700
Lightly Active (walking 2–3×/week)2,4001,950
Moderately Active (exercise 3–5×/week)2,7002,200
Very Active (hard exercise 6–7×/week)3,0002,450
Extremely Active (athlete/physical labor)3,3502,700

Where Do Your Burned Calories Go?

Your total daily calorie burn (TDEE) is made up of three components:

Component% of TotalWhat It Is
BMR60–75%Calories burned at rest — heart, lungs, brain, cells. Learn the difference between TDEE and BMR.
Physical Activity15–30%Exercise + daily movement (NEAT). Track yours with our Calorie Burn Calculator.
TEF5–15%Calories burned digesting food. Calculate yours with our TEF Calculator.

Calories Burned by Body Weight

Heavier people burn more calories at rest because they have more tissue to maintain. Here's how daily burn varies by weight for a moderately active 30-year-old:

Body WeightMen (mod. active)Women (mod. active)
120 lb (54 kg)2,2501,900
140 lb (64 kg)2,4502,050
160 lb (73 kg)2,6502,200
180 lb (82 kg)2,8502,350
200 lb (91 kg)3,0502,500
220 lb (100 kg)3,2502,650
250 lb (113 kg)3,5002,850

Frequently Asked Questions

How many calories does the average person burn a day without exercise?

Without any exercise, the average sedentary adult burns roughly 1,600–1,800 calories (women) or 2,000–2,200 calories (men) per day. This is primarily from your BMR plus minimal daily movement. Use our TDEE Calculator with the "Sedentary" setting for your personal estimate.

Do you burn more calories as you age?

No — you burn fewer calories as you age. BMR decreases by about 1–2% per decade after age 20 due to loss of muscle mass and hormonal changes. This is why maintaining muscle through resistance training becomes increasingly important with age.

How many calories does your body absorb in a day?

Your body absorbs about 90–95% of calories from a typical mixed diet. Fiber, highly processed foods, and cooking methods can affect absorption rates. However, for practical purposes, calorie counts on food labels are accurate enough for weight management.

How can I find out exactly how many calories I burn?

The most accurate methods are: (1) track your food intake and weight for 3+ weeks — if weight stays stable, that's your TDEE; (2) use a metabolic testing lab (indirect calorimetry); (3) start with our TDEE Calculator estimate and adjust based on real results over 2–4 weeks.
