Sedentary vs Active Calorie Difference
Calculate how many more calories you burn each day, week and year by being active instead of sedentary, based on your body measurements.
How Much More Do You Burn By Moving More?
Enter your age, height, weight and activity level. The calculator estimates your basal metabolic rate and daily energy needs for a sedentary and an active lifestyle.
Sedentary vs Active Calorie Estimator
Uses the Mifflin-St Jeor equation with standard activity multipliers.
Understanding Calorie Burn
Key concepts for energy expenditure
BMR
Mifflin-St Jeor: BMR = 10 × kg + 6.25 × cm − 5 × age + 5 (men) or − 161 (women). This is energy burned at rest.
Activity Multiplier
Daily energy = BMR × activity factor. Factors range from 1.2 (sedentary) to 1.9 (very active).
Weekly And Yearly Totals
Multiply the daily difference by 7 and 365 to see the cumulative effect of staying active.
Fat Equivalent
About 7,700 kcal equals 1 kg of body fat, though real weight change depends on diet, metabolism and adaptation.
Activity Level Multipliers
Standard multipliers applied to your basal metabolic rate.
| Activity Level | Multiplier | Description | Example |
|---|---|---|---|
| Sedentary | 1.2 | Little or no exercise | Desk job |
| Lightly active | 1.375 | Light exercise 1 – 3 days | Walking commute |
| Moderately active | 1.55 | Exercise 3 – 5 days | Regular gym user |
| Very active | 1.725 | Hard exercise 6 – 7 days | Daily training |
| Extra active | 1.9 | Physical job plus training | Athlete or labourer |
| Typical Gap | Sed. to Active | ~300 – 600 kcal/day | Depends on body size |
Sedentary vs Active Calculator FAQ
Answers to common questions about this calculator.
Typically 300 to 600 or more calories per day compared with a sedentary person of the same size, depending on intensity and duration.
Basal metabolic rate is the energy your body needs at rest to maintain basic functions such as breathing and circulation.
It is a good estimate, but individual metabolism varies by about 10%. Use it as a guide and adjust based on real results.
Only if you eat less than you burn. Combining activity with a modest calorie deficit is most effective.
