Biking Calorie Calculator
A 155 lb rider cycling at 12-13.9 mph for 30 minutes burns about 295 calories. This biking calorie calculator estimates the calories you burn from your weight, riding speed, and time in the saddle. It uses MET values from the Compendium of Physical Activities, the same reference researchers use, so a moderate 13 mph pace scores twice the burn rate of a slow, leisurely ride under 10 mph. Speed matters more for cycling than for walking because wind resistance rises fast as you go faster. That is why the jump from a light effort pace to a racing pace roughly doubles the calorie burn per minute, even though your legs are only moving somewhat harder.
Quick answer
Calories burned depend on three things, your body weight, your cycling speed, and how long you ride.

What this tells you
- •Calories burned depend on three things, your body weight, your cycling speed, and how long you ride.
- •Each speed bucket has a MET value, a multiple of resting energy use. Riding at 12-13.9 mph is 8.0 METs, meaning 8 times the calories you burn sitting still.
- •The formula is calories per minute = MET x 3.5 x weight in kg / 200.
- •Heavier riders burn more calories at the same speed because moving more mass takes more energy.
- •Wind, hills, and stopping at lights all change real-world burn, this tool assumes flat, steady outdoor riding.
How to Use
- 1Enter your body weight and pick pounds or kilograms.
- 2Enter how many minutes you rode or plan to ride.
- 3Choose your average riding speed. If you are not sure, 12-13.9 mph is a typical moderate-effort pace on a road bike.
- 4Click Calculate to see your estimated calorie burn.
- 5Read the total calories burned, plus the hourly burn rate, estimated distance, and MET value used.
How It Works
Formula
calories per minute = MET x 3.5 x weight (kg) / 200MET stands for metabolic equivalent of task. Sitting quietly is 1 MET, and each cycling speed bucket has a measured MET value, from 4.0 at a leisurely pace under 10 mph up to 15.8 at a racing pace over 20 mph. Multiply the MET by 3.5, then by your weight in kilograms, and divide by 200 to get calories per minute. Multiply by your riding time for the total. For example, a 70.3 kg rider at 8.0 METs burns about 9.8 calories a minute, so a 30 minute ride at that pace burns about 295 calories.

Worked Examples
30 minute ride at 12-13.9 mph, 155 lb rider
155 lb is 70.3 kg. At 8.0 METs, that is about 9.8 calories a minute, times 30 minutes.
1 hour ride at 16-19 mph, 180 lb rider
180 lb is 81.6 kg. At 12.0 METs, the burn rate is about 17.1 calories a minute for 60 minutes.
45 minute ride at 10-11.9 mph, 70 kg rider
At 6.8 METs, a 70 kg rider burns about 8.3 calories a minute, times 45 minutes.
20 minute leisurely ride under 10 mph, 140 lb rider
140 lb is 63.5 kg. At 4.0 METs, that is about 4.4 calories a minute, times 20 minutes.
Calories Burned Biking 30 Minutes by Speed
Estimated calories for a 155 lb (70.3 kg) rider cycling 30 minutes at each speed bucket.
| Speed | MET | Calories in 30 min |
|---|---|---|
| Under 10 mph, leisurely | 4.0 | 148 |
| 10-11.9 mph, light effort | 6.8 | 251 |
| 12-13.9 mph, moderate effort | 8.0 | 295 |
| 14-15.9 mph, vigorous effort | 10.0 | 369 |
| 16-19 mph, racing/fast | 12.0 | 443 |
| Over 20 mph, racing, very fast | 15.8 | 583 |
Values assume flat, paved terrain with no significant wind. A heavier or lighter rider will burn proportionally more or less.
Why cycling speed changes calorie burn so much
Cycling calorie burn rises faster with speed than walking does, mostly because of wind resistance. Air drag grows with roughly the square of your speed, so pushing from a light-effort 11 mph to a racing 20 mph pace demands far more than double the power output. That is why the MET values in this calculator jump from 6.8 at light effort to 15.8 at racing speed, nearly four times the intensity for less than double the speed.
Body weight plays a steady, linear role in the formula. A 200 lb rider and a 130 lb rider moving at the identical pace and effort level use the same MET, but the heavier rider burns more total calories per minute because more mass is being moved through space. This mirrors how a car with a bigger engine burns more fuel to cover the same distance at the same speed.
Real rides rarely hold one constant speed. Traffic lights, hills, and drafting behind other riders all shift your actual effort above or below the flat-road average used here. Riders training with a power meter or heart rate monitor get a more precise number, but the MET-based estimate is a solid starting point for planning nutrition or tracking activity trends over time.
Common mistakes
- Comparing outdoor road cycling to a stationary bike at the same reported speed. Resistance and terrain differ between the two, so the MET value does not transfer directly.
- Ignoring wind and hills, which raise real effort above the flat-road MET values used in this calculator.
- Treating the estimate as exact rather than a population-average range that varies with fitness and bike setup.
- Using total ride time instead of actual pedaling time. Long stops at intersections or coasting downhill do not burn the same calories as sustained pedaling.
- Picking a speed bucket that reflects your top speed rather than your average pace for the whole ride.
