This calculator estimates the calories burned during moderate-intensity cycling — the steady, conversational pace that builds endurance without max effort. Whether you’re commuting, enjoying a weekend ride, or training for a charity event, knowing your energy expenditure helps you plan nutrition and track progress.
Moderate cycling (12–14 mph / 19–22 km/h on flat terrain) typically burns 400–600 calories per hour for a 155‑lb (70 kg) person. Our tool refines this estimate using your weight, duration, and a MET value of 8.0 — the standard for moderate cycling. Perfect for fitness enthusiasts, weight‑watchers, and anyone adding low‑impact cardio to their routine.

How to Use This Tool
Enter your body weight and the duration of your cycling session. Choose the correct units (kg/lb, minutes/hours) from the dropdowns. Click Calculate to see your estimated total calories burned, plus per‑minute and per‑hour rates. Use the Quick fill buttons to load common examples. Press Reset to clear all fields.
Formula Explained
The calculation follows the standard MET‑based formula:
Calories burned = MET × 3.5 × weight (kg) × duration (hours) / 200
For moderate cycling, we use a MET value of 8.0, which corresponds to cycling at 12–14 mph (19–22 km/h) on level ground. This value comes from the Compendium of Physical Activities (code 01015). The formula accounts for the oxygen cost of the activity and converts it to kilocalories. The constant 3.5 represents the metabolic equivalent of 1 MET in mL/kg/min, and dividing by 200 converts the result from mL O₂ to kcal.
Worked Examples
Example 1: A 70 kg person cycles for 60 minutes at moderate intensity.
Calories = 8.0 × 3.5 × 70 × 1 / 200 = 9.8 kcal/min → 588 kcal total.
Example 2: A 155 lb person cycles for 45 minutes.
First convert weight: 155 lb × 0.4536 = 70.3 kg. Duration = 45/60 = 0.75 hr.
Calories = 8.0 × 3.5 × 70.3 × 0.75 / 200 = 7.4 kcal/min → 331 kcal total.
Example 3: A 90 kg person cycles for 2 hours (120 minutes).
Duration = 2 hr. Calories = 8.0 × 3.5 × 90 × 2 / 200 = 25.2 kcal/min → 1512 kcal total. This shows how longer rides significantly increase energy expenditure.
Tips for Accurate Estimation
- Use your actual body weight — even small differences matter. Weigh yourself in the morning before eating for consistency.
- Moderate intensity means you can hold a conversation but are breathing harder than usual. If you're huffing and puffing, you're likely at vigorous intensity (MET 10+).
- Terrain, wind, and bike type affect actual effort. This calculator assumes flat, paved roads with a standard road bike. Mountain biking on trails increases MET to 8.5–9.0.
- For the most precise results, use a heart rate monitor or power meter. Power meters measure actual work output and can improve accuracy by 10–20%.
- Hydration and temperature also influence calorie burn. Hot weather increases cardiovascular demand slightly.
Frequently Asked Questions
Q: Is moderate cycling good for weight loss?
A: Yes. A 155 lb person can burn ~500 kcal per hour. Combined with a balanced diet, regular moderate cycling (3–5 times per week) supports steady fat loss. For example, cycling 4 times a week for 45 minutes each session burns about 1324 kcal weekly, which can lead to ~0.2 kg (0.4 lb) of fat loss per week without dietary changes.
Q: How does this compare to walking or jogging?
A: Moderate cycling (MET 8.0) burns more calories than brisk walking (MET 4.3) but less than jogging (MET 7.0–9.0). It's easier on the joints than running, making it ideal for people with knee or hip issues. A 70 kg person burns about 294 kcal walking briskly for 60 minutes, versus 588 kcal cycling moderately.
Q: Can I use this for stationary cycling?
A: Yes, if you maintain a moderate effort (RPE 5–6 out of 10). Stationary cycling at a steady pace has a similar MET value. However, many stationary bikes overestimate calories by 20–30%, so this calculator may give a more realistic estimate.
Q: What if I cycle uphill or downhill?
A: Uphill cycling increases MET to 10–14; downhill reduces it. This calculator is for flat terrain only. For hilly routes, consider using an average MET of 9.0–10.0 for a mixed ride.
Q: How accurate is the MET formula?
A: The MET formula provides a population average estimate. Individual variation can be ±15–20% due to factors like metabolism, cycling efficiency, and body composition. For personalized data, a lab test or power meter is recommended.
Real-World Applications
Use this tool to plan your nutrition for long rides, track weekly calorie expenditure, or compare cycling to other low‑impact activities like walking or swimming. Many cyclists aim for a 500‑kcal deficit per day for weight loss — a 60‑minute moderate ride gets you most of the way there. For endurance events like century rides (100 miles), knowing your calorie burn helps you plan carbohydrate intake: aim for 30–60 g of carbs per hour of riding. This calculator also helps you estimate the calorie cost of your commute: a 30‑minute ride each way burns about 294 kcal daily, or 1470 kcal per week.
