Calories Burned Walking 30 Minutes
A 30-minute brisk walk burns roughly 110 to 170 calories for most adults, depending on body weight.
At a glance
The short answer
Walking at a brisk pace (3.5 MET) for 30 minutes burns about 129 calories for a 155 lb person. Lighter walkers burn closer to 108 calories, and heavier walkers can reach 171 calories in the same half hour.
| Body Weight | Calories Burned (30 min walk) |
|---|---|
| 130 lb | 108 kcal |
| 155 lb | 129 kcal |
| 180 lb | 150 kcal |
| 205 lb | 171 kcal |

Energy Expenditure
How the estimate works
The calculator uses the standard MET formula: kcal = MET x 3.5 x weight in kg / 200 x minutes. Brisk walking is rated at 3.5 MET, meaning it burns 3.5 times the energy of sitting quietly. Your weight is converted to kilograms, so the estimate scales directly with body mass.
Walking longer or carrying more
Because the formula is linear in time and weight, doubling the walk doubles the burn: a 180 lb person walking 60 minutes burns about 300 calories. Walking uphill, carrying a backpack, or pushing a stroller raises intensity above 3.5 MET, so real-world burn is often higher than the flat-pace estimate.
Making your walks count
For weight loss, consistency beats intensity. A daily 30-minute walk at 155 lb adds up to roughly 900 calories per week — about a quarter pound of fat per month on its own, and more when paired with a modest calorie deficit.
Frequently Asked Questions
Does walking speed change the calorie count?
Yes. This tool uses 3.5 MET, which matches a brisk walk around 3.5 mph. A slow stroll is closer to 2.5-3 MET and burns less, while fast or uphill walking can reach 4-5 MET.
Is walking 30 minutes a day enough to lose weight?
It helps, but slowly. At about 130 calories per day, walking alone burns off roughly one pound every four weeks. Combining it with a small diet change produces much faster results.
Why do heavier people burn more calories walking?
Moving more body mass takes more energy. The formula multiplies by your weight in kilograms, so calorie burn rises in direct proportion to body weight.
How accurate is a MET-based estimate?
It is based on population averages. Fitness level, terrain, and walking efficiency can shift your actual burn by 10-20% in either direction.
