Calories Burned

Calories Burned is a free browser-based tool that helps you estimate calories burned with met values for 10+ activities. It is part of ToolsMonk's calculators collection, so you can finish the job without downloading software, creating an account, or jumping between multiple websites.

This tool is especially useful for workflows such as estimating calories burned in a workout or activity, factoring exercise into a calorie deficit for weight loss, and comparing the energy cost of different activities. Because it runs directly in your browser, you can use it on desktop, tablet, or mobile while keeping the process fast and easy for one-off tasks as well as repeat work.

Calories Burned is designed for people who want a practical, privacy-friendly workflow with instant results inside the larger ToolsMonk library.

Calories Burned Calculator estimates the energy you expend during exercise and activities from the activity type, its duration, and your body weight — the 'energy out' counterpart to calorie-intake planning.

It works from MET (Metabolic Equivalent of Task) values, where each activity carries an intensity rating and calories burned ≈ MET × weight × hours. That's why heavier people and longer, more intense sessions burn more — but it's a population-average estimate, not a personal measurement.

Accuracy deserves honesty: real burn varies with fitness, body composition, effort, and metabolism, and estimates from every source — including trackers and gym machines — tend to run high. So use the figure to compare activities and track trends, not as an exact count. In particular, be wary of 'eating back' exercise calories one-for-one, since overestimated burn can quietly cancel a weight-loss deficit.

It complements the Calorie Calculator (intake) and TDEE (which already bundles an activity level) — together they give the energy-in versus energy-out picture. It's informational, not medical advice, and your details never leave your browser. Pair it with the other ToolsMonk health calculators.
