Raking Leaves Calorie Formula: How to Calculate Your Calorie Burn
The raking leaves calorie formula uses MET × weight (kg) × time (hours). A 70 kg person burns 140–175 calories in 30 minutes depending on intensity. Full tables and worked examples inside.
The raking leaves calorie formula is: Calories = MET × Weight (kg) × Time (hours). Raking leaves has a MET (Metabolic Equivalent of Task) value ranging from 4.0 (light) to 5.0 (vigorous) according to the Ainsworth Compendium of Physical Activities, placing it firmly in the moderate-intensity aerobic exercise category.

The MET Formula for Raking Leaves
The calorie formula for any physical activity is:
Calories = MET × Weight (kg) × Time (hours)
For raking leaves, MET values are:
| Intensity Level | MET Value | Description |
|---|---|---|
| Light Raking | 4.0 | Small yard, light leaf coverage, slow pace |
| Moderate Raking | 4.5 | Medium yard, typical fall coverage, steady pace |
| Vigorous Raking | 5.0 | Large yard, heavy leaf coverage, fast pace |
These values come from the Compendium of Physical Activities (Ainsworth et al., 2011), the gold-standard reference for exercise energy expenditure used in scientific research and clinical settings worldwide.
Worked Calculation Examples
Example 1: 70 kg person, 30 minutes, moderate raking (MET 4.5)
Calories = 4.5 × 70 × (30 ÷ 60)
Calories = 4.5 × 70 × 0.5
Calories = 157.5 ≈ 158 kcal
Example 2: 85 kg person, 45 minutes, vigorous raking (MET 5.0)
Calories = 5.0 × 85 × (45 ÷ 60)
Calories = 5.0 × 85 × 0.75
Calories = 318.75 ≈ 319 kcal
Example 3: 60 kg person, 1 hour, light raking (MET 4.0)
Calories = 4.0 × 60 × (60 ÷ 60)
Calories = 4.0 × 60 × 1.0
Calories = 240 kcal

What Does MET Actually Mean?
MET stands for Metabolic Equivalent of Task. It compares the energy cost of an activity to your resting metabolic rate.
- MET 1.0 = sitting at rest (your baseline)
- MET 3.0 = brisk walking
- MET 4.5 = moderate raking (this activity)
- MET 8.0 = running at 8 km/h
A MET of 4.5 means your body burns 4.5 times more energy than it does while sitting still. This places moderate raking in the same intensity range as brisk walking, leisurely swimming, and doubles tennis — all recognized as moderate-intensity aerobic exercise.
How Raking Compares to Other Yard Work and Common Activities
Understanding where raking falls in the spectrum of physical activities helps you gauge its fitness value:
| Activity | MET Value | Calories / 30 min (70 kg) |
|---|---|---|
| Slow walking | 2.5 | 88 cal |
| Brisk walking | 3.5 | 123 cal |
| Gardening (general) | 3.5–4.5 | 123–158 cal |
| Raking Leaves (light) | 4.0 | 140 cal |
| Raking Leaves (moderate) | 4.5 | 158 cal |
| Lawn mowing (push mower) | 4.5 | 158 cal |
| Raking Leaves (vigorous) | 5.0 | 175 cal |
| Snow shoveling (light) | 5.0 | 175 cal |
| Snow shoveling (moderate) | 6.0 | 210 cal |
| Snow shoveling (heavy/wet) | 7.5 | 263 cal |
| Jogging | 7.0 | 245 cal |
Raking is similar to lawn mowing at comparable effort levels, and burns considerably fewer calories than snow shoveling due to the much lighter weight of leaves versus snow.
Factors That Change the Effective Calorie Burn
The MET formula gives a solid baseline, but actual calorie burn varies based on:
Leaf type and moisture: Dry autumn leaves are light; wet or matted leaves require significantly more force per stroke. Raking wet leaves effectively pushes the intensity from MET 4.5 toward MET 5.0 or beyond.
Bagging and hauling: If your fall cleanup includes bending to fill bags, carrying them to the curb, or loading them into a truck, your total session calorie burn will exceed the raking-only estimate by 10–20%.
Terrain: Raking on a slope or around garden beds requires more coordination and isometric muscle effort than flat, open lawn.
Body weight: The formula scales linearly — a 90 kg person always burns exactly 50% more calories than a 60 kg person at the same MET and duration.
Fitness level: More fit individuals tend to be more efficient, so their actual calorie burn may be slightly lower than the formula predicts for a given perceived effort level.
How to Use the Formula for Your Own Calculation
To calculate your raking leaves calorie burn manually:
- Find your weight in kg (divide lbs by 2.205 if needed)
- Choose your MET value — 4.0 (light), 4.5 (moderate), or 5.0 (vigorous)
- Convert your time to hours — divide minutes by 60
- Multiply: Calories = MET × weight × time

Frequently Asked Questions
How many calories does raking leaves burn per hour?
At moderate intensity (MET 4.5), raking leaves burns approximately 270 calories per hour for a 60 kg person, 315 calories per hour for a 70 kg person, and 405 calories per hour for a 90 kg person.
How accurate is the MET formula for raking leaves?
The MET formula is accurate to within approximately ±20–30% for most people. Individual variation in technique, body composition, fitness level, and yard conditions means the formula is best treated as a reliable estimate rather than a precise measurement.
Can raking leaves count toward my weekly exercise goals?
Yes. At MET 4.5, moderate raking qualifies as moderate-intensity aerobic activity, which counts toward the 150 minutes per week recommended by the American Heart Association and World Health Organization.
