What this calculator estimates
This calorie calculator estimates your basal metabolic rate and then adjusts it based on your activity level to provide a daily calorie target for maintenance. It also gives simple calorie ranges for mild weight loss and gradual weight gain.

It is useful when you want a practical starting point for nutrition planning without manually doing BMR and TDEE calculations.
What to keep in mind
Calorie needs vary from person to person. This tool gives a strong starting estimate, but real needs can shift based on sleep, training, body composition, medication, hormones, and health conditions.

How the estimate is calculated
- • Choose metric or imperial units, then enter age, sex, height, weight, and activity level.
- • The calculator estimates your basal metabolic rate using the Mifflin-St Jeor equation.
- • It multiplies that baseline by your chosen activity level to estimate maintenance calories.
- • It then suggests gentle calorie targets for weight loss and weight gain so you have a simple planning range.

FAQs
Common questions
What is maintenance calories?
Maintenance calories are the approximate number of calories you need each day to keep your current body weight stable.
Is this the same as a TDEE calculator?
Yes. This tool estimates total daily energy expenditure by combining your basal metabolic rate with your activity level.
Should I follow the number exactly?
It is better to treat the result as a starting point. Track how your body responds over time, then adjust intake based on real progress and how you feel.
