Calorie Calculator – Free Online Tool
Estimate daily calories, TDEE, weight loss calories, maintenance calories, and macro targets with practical safety flags and meal splits.
Free Calorie Calculator for TDEE, Weight Loss, and Macros
ToolsMint Calorie Calculator estimates how many calories you burn each day, also called TDEE, and turns that estimate into a practical target for maintenance, fat loss, gentle weight loss, or lean gain. It also creates protein, carb, and fat macro targets so the result is easier to use than a single calorie number.
Maintenance Calories and Calorie Deficit Calculator
Use the maintenance calorie estimate as your starting point, then compare goal calories against a moderate deficit or surplus. The assistant flags targets that fall below common calorie floors or cut more than 25% below maintenance, helping beginners avoid overly aggressive plans.
Macro Calculator With Meal Splits
Choose balanced, high-protein, lower-carb, or endurance macro styles. The calculator converts your calorie target into grams of protein, carbohydrates, and fat, then shows a simple calories-per-meal split for people who plan breakfast, lunch, dinner, and snacks.
How to Use the Calorie Calculator
Enter your age, height, weight, formula profile, activity level, and goal. Pick a macro style and number of meals per day. Review maintenance calories, goal calories, weekly pace, macros, and assistant checks, then copy the plan or download a CSV for tracking.
Private Browser-Based Calorie Planning
Your age, weight, height, goals, and nutrition estimates stay in your browser. The tool calculates locally, requires no account, and does not upload personal health inputs to ToolsMint.
