Free Calorie Calculator

Figuring out how many calories your body actually needs each day isn't as simple as picking a random number — it depends on your age, weight, height, gender, and how active you are. Our Calorie Calculator takes all of that into account so you get an estimate that's actually relevant to you.

Here's how it works: you enter your basic stats and activity level, and the tool first calculates your BMR (Basal Metabolic Rate) — the calories your body burns just to keep functioning at rest — using established formulas like Mifflin-St Jeor. It then factors in your activity level to give you your TDEE (Total Daily Energy Expenditure), which is the number of calories you'd need to maintain your current weight. From there, you get a clear picture of where your maintenance calories sit.

This is a helpful starting point for anyone curious about their nutrition — whether you're tracking macros, working with a trainer, or just want to understand your body's energy needs a bit better. Keep in mind this gives an estimate, not a precise medical figure, so it's always worth checking in with a doctor or nutritionist for personalized guidance, especially if you have specific health goals or conditions.
