Calorie calculator On-device
BMR, TDEE, meal totals and a calm goal planner
Estimates, not prescriptions — for medical or dietary decisions, see a doctor or dietitian.
Free calorie calculator — BMR, TDEE by activity level, a meal totaler, and a calm goal-and-macros planner. Works entirely on your device.
About this tool
What you provide
- Sex, age, height, weight and activity level
- Optionally your meal's ingredients with their calories and protein, carbs and fat
- A daily calorie adjustment and a macro split for the goal planner
What you get
- Your BMR and TDEE in kcal per day
- Meal and per-serving totals with protein, carbs and fat
- A daily calorie target with the matching macro grams
Limits
- Estimates, not prescriptions — for medical or dietary decisions see a doctor or dietitian.
- The formulas are built for adults; energy needs for children and teens should be assessed with a pediatrician or dietitian.
- It reports numbers only and gives no diet or exercise advice; it flags a deficit steeper than -750 kcal/day or a target under 1,200 kcal/day, but never blocks it.
How to use it
-
Work out your daily energy
On the BMR/TDEE tab pick cm / kg or ft-in / lb, enter your age, sex, height and weight, and choose an activity level from sedentary to very active to see your BMR and TDEE in kcal per day.

Total a meal
On the Meal totaler tab press Add ingredient for each item, enter its calories and optionally its protein, carb and fat grams, then set the number of servings to get the per-serving figure.
-
Plan a goal
On the Goal + macros tab drag the daily calorie adjustment slider to set a deficit or surplus against your TDEE, then keep the Balanced 30/40/30 split or switch to Custom percentages to see the protein, carb and fat grams for the target.
