🔥 Calorie Burn Calculator
Pick an activity, enter your bodyweight and duration, and estimate the calories you burn using research-based MET values — handy for comparing workouts and planning your energy balance.
🔥 Estimate Calories Burned
What is a Calorie Burn Calculator?
Different activities burn energy at very different rates, and a calorie-burn calculator estimates how much you spend in a given session. This one uses MET values — standardized intensity ratings for dozens of activities — scaled by your bodyweight and the time you train.
Use it to compare a run against a lifting session, plan a calorie deficit or surplus, or sanity-check what your tracker reports. The result is a general fitness estimate, not medical advice — consult a doctor or qualified trainer, warm up, and use proper form, especially when starting a new activity.
❓ Frequently Asked Questions
How are calories burned during exercise estimated?
This calculator uses MET values — metabolic equivalents that rate how intense an activity is relative to sitting still — multiplied by your bodyweight and the time spent. It's the same method fitness research uses for population estimates, but individual burn varies with fitness, efficiency, and effort.
Why does my fitness tracker show a different number?
Trackers add heart-rate data and proprietary algorithms, while MET tables use averages, so the two can differ by 10–20% or more. Neither is exact — treat any single figure as a ballpark and look at trends over weeks rather than chasing a precise per-session number.
Should I eat back the calories I burn?
It depends on your goal and how the burn was estimated, and estimates tend to run high. If you're managing weight, lean toward eating back only a portion. These are general fitness estimates, not medical advice — consult a doctor or registered dietitian for individual energy needs.
