One of the most common questions in health and fitness is:
“How many calories do I need to maintain my weight?”
The answer depends on your age, gender, weight, height, and activity level. Eating above your needs leads to weight gain, while eating below them leads to weight loss. The sweet spot—your maintenance calories—is the number of calories your body needs daily to keep your weight stable.
Our Maintenance Calorie Calculator makes it simple to find this number. Whether you want to maintain your weight, adjust after dieting, or build a nutrition plan, this tool provides quick, accurate results.
How the Maintenance Calorie Calculator Works
The calculator estimates your Total Daily Energy Expenditure (TDEE), which is the sum of:
- BMR (Basal Metabolic Rate): Calories burned at rest to keep you alive.
- Activity Calories: Energy used during movement, exercise, and daily tasks.
Your maintenance calories = TDEE.
For example:
- If your TDEE is 2,400 calories, eating about 2,400 calories daily will keep your weight steady.
How to Use the Maintenance Calorie Calculator
Follow these simple steps:
- Enter Your Age – Your metabolism slows slightly as you age.
- Select Gender – Men and women have different calorie needs.
- Input Height & Weight – Used to calculate your BMR.
- Choose Activity Level – Sedentary, lightly active, moderately active, very active, or extra active.
- Click Calculate – Instantly see your maintenance calories.
Example Calculation
Let’s say:
- Age: 30
- Gender: Female
- Height: 165 cm
- Weight: 65 kg
- Activity Level: Lightly active
Results:
- BMR: ~1,430 calories/day
- TDEE: ~1,900 calories/day
- Maintenance Calories: ~1,900 calories/day
This means she should eat around 1,900 calories daily to maintain her current weight.
