Calories Burned Calculator
Estimate calories burned from activity type, MET value, body weight, workout duration, and weekly training frequency.
Last Updated: April 2026
Activity Calorie Estimate
Calories burned estimates vary by body size, pace, terrain, fitness, and measurement method. Use this as a planning range, not a lab-grade energy measurement.
Activity Inputs
MET methodBrisk walking pace for many adults.
Select Custom MET to edit this value.
Exercise Estimate Disclaimer
This calculator provides educational estimates only. It is not medical, nutrition, or training advice. Actual calories burned vary by fitness level, pace, terrain, health status, medications, environment, and measurement method. Consult a qualified clinician before starting vigorous exercise if you have symptoms, chronic conditions, or activity restrictions.

Health credentialed review: professional reliance limit
This page is for general education and planning. It is not medical diagnosis, treatment, nutrition therapy, or a substitute for care from a qualified clinician. Results should be treated as a preliminary estimate, not a filing instruction, diagnosis, product recommendation, eligibility decision, or compliance sign-off. Required professional review: licensed physician, registered dietitian, qualified clinician. Source expectation: Review should cite public-health, academic, medical, or recognized clinical sources for formulas and safety thresholds.
Nutrition Planning Path
Nutrition pages should connect protein, calories, macros, and body-composition context while keeping medical limitations explicit.
Estimate calories
Set energy context before changing protein or macro targets.
Calculate protein
Estimate a practical daily protein range.
Translate macros
Convert energy goals into macro grams for planning.
Screen body composition
Use body-composition estimates cautiously and avoid diagnosis from calculator output.

How to Use This Calculator
Step 1: Choose units and activity
Select pounds or kilograms, then choose a preset activity or custom MET value.
Step 2: Enter body weight and duration
Provide weight and workout minutes so the MET formula can estimate session calories.
Step 3: Set weekly frequency
Enter sessions per week to estimate weekly and monthly activity calories.
Step 4: Review intensity and assumptions
Check session burn, calories per hour, weekly totals, and moderate or vigorous context.
How This Calculator Works
The calculator uses a MET-based activity equation: calories burned equals MET value times 3.5 times body weight in kilograms, divided by 200, then multiplied by activity minutes. This produces a practical field estimate for many common activities.
MET values represent the absolute energy cost of activity. CDC guidance describes moderate intensity as about 3.0 to 5.9 METs and vigorous intensity as 6.0 METs or more. The calculator uses those cutoffs to label the selected workout.
The estimate scales linearly with time, MET value, and body weight. That makes the arithmetic transparent, but it also means real-world factors such as hills, heat, wind, rest intervals, technique, and fitness can move actual calorie burn above or below the estimate.
What You Need to Know
1) What the MET Formula Uses
A calories-burned estimate needs three main inputs: activity intensity, body weight, and time. The MET value handles intensity, body weight scales the energy cost, and duration converts the per-minute estimate into a session total.
| Input | Meaning | Why it matters |
|---|---|---|
| MET | Metabolic equivalent of task. | Higher values mean higher estimated energy cost. |
| Body weight | Converted to kilograms for the formula. | For the same activity, a higher body weight generally increases calorie burn. |
| Duration | Activity minutes. | Longer sessions scale the result linearly. |
| Formula | MET x 3.5 x kg / 200 x minutes. | Standard field estimate for activity energy expenditure. |
2) Moderate vs Vigorous Activity
Absolute intensity uses MET cutoffs, while relative intensity depends on how hard the activity feels for your fitness level. A pace that feels moderate to one person may feel vigorous to another, so use symptoms and perceived effort alongside the calculator.
| Intensity | MET range | Practical meaning |
|---|---|---|
| Light | Below 3 METs | Easy movement or low physical demand. |
| Moderate | 3.0 to 5.9 METs | Breathing and heart rate rise, but conversation is usually possible. |
| Vigorous | 6.0 METs or more | Harder effort where talking becomes difficult. |
3) How to Use This With Other Health Tools
Calories burned from exercise are only one part of energy balance. Pair this activity estimate with the Calorie Calculator or TDEE & Macro Calculator if you also need daily calorie intake, maintenance calories, or macro targets.
