Gardening is one of the most rewarding ways to stay active, and planting is at the heart of it. Whether you're setting out seedlings, digging holes, or filling pots with soil, you're engaging your whole body in a gentle, low-impact workout. This calculator estimates the calories you burn during 25 minutes of planting based on your weight and the intensity of your effort.
Use it to track your gardening sessions, plan your daily movement, or simply satisfy your curiosity about how much energy a productive afternoon in the garden really uses. The tool is built on the standard MET (Metabolic Equivalent of Task) method, the same approach used by exercise scientists and fitness trackers. Just enter your weight, choose your planting intensity, and hit calculate to see your estimated calorie burn, plus a breakdown of the math behind it.

How to Use This Tool
Enter your body weight in kilograms or pounds, select the intensity that best matches your planting session, and click Calculate. The result shows your estimated calorie burn for 25 minutes of planting, along with a breakdown of the calculation. Use the quick-select buttons to instantly fill in common weights, or type your own. The reset button clears all fields and results.
How It Works
This calculator uses the MET (Metabolic Equivalent of Task) method, a standard way to estimate energy expenditure. MET values represent the ratio of energy spent during an activity compared to resting metabolism. For planting, we use the following MET values:
- Light intensity (casual planting, slow pace): MET 3.5
- Moderate intensity (steady planting, bending and reaching): MET 4.5
- Vigorous intensity (fast planting, heavy soil, continuous effort): MET 6.0
The formula is: Calories burned = MET × 3.5 × weight (kg) ÷ 200 × duration (minutes). This is the same formula used by many fitness trackers and health organizations. For example, a 70 kg person planting at moderate intensity for 25 minutes burns approximately 4.5 × 3.5 × 70 ÷ 200 × 25 = 138 kcal.
Worked Examples
Example 1: A 60 kg person planting at light intensity for 25 minutes: 3.5 × 3.5 × 60 ÷ 200 × 25 = 92 kcal.
Example 2: A 155 lb (70.3 kg) person planting at vigorous intensity: 6.0 × 3.5 × 70.3 ÷ 200 × 25 = 184 kcal.
Example 3: A 80 kg person planting at moderate intensity: 4.5 × 3.5 × 80 ÷ 200 × 25 = 158 kcal.
Tips & Best Practices
- Be honest about your intensity. If you're taking frequent breaks, choose light. If you're moving continuously and breaking a sweat, choose vigorous.
- Use a kitchen scale or bathroom scale to get an accurate weight. Even a few kilograms can change the estimate.
- Planting is a full-body activity — it engages your legs, core, and arms. To increase calorie burn, add squats or lunges as you plant.
- Combine planting with other gardening tasks like weeding or watering for a longer, more varied workout.
Factors Affecting Accuracy
Individual calorie burn varies based on age, gender, muscle mass, and fitness level. The MET method provides a population average, so your actual burn may be higher or lower. Also, the intensity of planting can vary greatly depending on soil type, tools used, and whether you're kneeling or standing. For the most accurate tracking, consider using a heart rate monitor or fitness watch.
Frequently Asked Questions
Is planting a good workout? Yes, planting is a low-impact activity that improves flexibility, strength, and endurance. It's especially beneficial for older adults or those with joint issues.
How many calories can I burn in an hour of planting? Multiply the 25-minute result by 2.4. For a 70 kg person at moderate intensity, that's about 330 kcal per hour.
Can I use this calculator for other gardening tasks? The MET values are specific to planting. For other tasks like weeding or mowing, you'd need different MET values. Check our CDC physical activity guidelines for general reference.
Why is the formula divided by 200? The 200 is a conversion factor that accounts for the average oxygen consumption per kilogram of body weight per minute. It's a standard constant in the MET formula.
