Raking leaves, grass clippings, or garden debris is a classic autumn chore that also happens to be a legitimate form of moderate-intensity exercise. The Raking MET Calculator helps you estimate the metabolic equivalent of task (MET) value for your raking session and converts it into calories burned, based on your body weight, the intensity of your effort, and how long you work.
Whether you're tracking daily activity for weight management, planning a weekend yard-work session, or simply curious about how many calories a big leaf pile can burn, this tool gives you a quick, evidence-based estimate. It uses the standard MET formula (calories = MET × weight in kg × duration in hours) and lets you choose between light, moderate, and vigorous raking intensities.
No special equipment needed — just enter your weight, pick your effort level, and hit calculate. You'll get your MET value, total calories burned, and a per-minute breakdown to help you plan your yard work like a pro.

Step-by-step breakdown
How to Use This Tool
Using the Raking MET Calculator is straightforward. Start by entering your body weight — you can switch between kilograms and pounds using the dropdown next to the input. Next, select the intensity level that best matches your raking effort: Light for slow, easy raking with frequent breaks; Moderate for steady, typical raking at a comfortable pace; or Vigorous for fast, heavy raking that gets your heart rate up. Finally, enter how long you plan to rake, either in minutes or hours. Click Calculate to see your estimated calories burned, the MET value used, calories per minute, and a step-by-step breakdown of the math. Use the quick-fill buttons to instantly populate common weight and duration values, and the Reset button to clear everything and start fresh.
How It Works
The calculator uses the standard metabolic equivalent (MET) formula, which is widely used in exercise science to estimate energy expenditure:
Calories burned = MET × weight (kg) × duration (hours)
One MET is the rate of energy expenditure while sitting at rest, roughly equal to 1 kcal per kilogram of body weight per hour. When you rake at a moderate pace, your body works harder than at rest, so the MET value increases. The MET values used here are based on the Compendium of Physical Activities, a research-backed resource that assigns MET values to hundreds of activities. For raking, the compendium lists values of 3.0 for light effort, 3.8 for moderate effort, and 4.5 for vigorous effort. These values assume an average adult; individual results may vary based on fitness level, terrain, and technique.
Worked Examples
Example 1: A 70 kg person rakes leaves at a moderate pace for 45 minutes. Weight in kg = 70, duration in hours = 45/60 = 0.75. Calories = 3.8 × 70 × 0.75 = 199.5 kcal.
Example 2: A 155 lb person (about 70.3 kg) rakes vigorously for 1 hour. Calories = 4.5 × 70.3 × 1 = 316.4 kcal.
Example 3: A 60 kg person does light raking for 30 minutes. Calories = 3.0 × 60 × 0.5 = 90 kcal.
Tips & Best Practices
- Maintain good posture: Keep your back straight and bend at the knees when lifting piles to avoid strain.
- Switch sides: Alternate which hand leads the rake to balance muscle use and prevent fatigue.
- Take breaks: If you're new to yard work, take a 5-minute break every 20–30 minutes to stay comfortable.
- Stay hydrated: Even in cool weather, raking can make you sweat. Drink water before, during, and after.
- Use the right rake: A lightweight, ergonomic rake reduces strain and makes the work more efficient.
Factors Affecting Accuracy
The MET values are averages and may not perfectly reflect your personal energy expenditure. Factors such as your fitness level, the weight of the rake, the density of leaves, the slope of your yard, and how much you bend or lift can all influence the actual calories burned. The calculator provides a solid estimate for planning and tracking, but for precise measurements, consider using a heart rate monitor or fitness tracker. Also note that the formula assumes a steady effort throughout the session; if you take long breaks, your actual burn will be lower.
Frequently Asked Questions
Is raking really exercise?
Yes. Raking is considered moderate-intensity physical activity by health organizations like the American Heart Association. It raises your heart rate, engages your arms, shoulders, core, and legs, and can contribute to the recommended 150 minutes of moderate activity per week.
How many calories does raking burn per hour?
For a 70 kg (154 lb) person, moderate raking burns about 266 kcal per hour (3.8 MET × 70 kg × 1 hr). Vigorous raking burns about 315 kcal per hour, and light raking about 210 kcal per hour.
Can I use this calculator for other yard work?
This calculator is specifically calibrated for raking. For other activities like mowing, weeding, or planting, you may want to use a dedicated calculator. For example, you can estimate calories for planting or sweeping with similar tools.
What is a MET value?
MET stands for Metabolic Equivalent of Task. It's a unit that measures the energy cost of physical activities relative to resting. A MET of 1 is resting, 3–6 is moderate activity, and 6+ is vigorous activity.
