What Is a Daily Calorie Calculator?

A Daily Calorie Calculator estimates how many calories your body needs each day based on your age, gender, height, weight, activity level, and fitness goal.

It first calculates your Basal Metabolic Rate (BMR), then adjusts it using your activity level to estimate the number of calories your body burns each day.

Activity Level Guide

Activity Level Description
Sedentary Little or no exercise.
Lightly Active Exercise 1–3 days each week.
Moderately Active Exercise 3–5 days each week.
Very Active Exercise 6–7 days each week.
Extra Active Very intense exercise or a physically demanding job.

How to Use Your Results

Your recommended calorie intake depends on your goal.

  • Lose Weight: Eat fewer calories than your maintenance level.
  • Maintain Weight: Eat approximately your maintenance calories.
  • Gain Weight: Eat more calories than your maintenance level.

Combine a balanced diet with regular physical activity for the best long-term results.
