Calorie Deficit Calculator
What is a calorie deficit calculator?
A calorie deficit calculator helps estimate how many calories you should eat per day to lose weight based on your maintenance calories.
What is a calorie deficit?
A calorie deficit happens when you eat fewer calories than your body burns. This is the basic principle behind weight loss.
How does this calculator work?
This calculator takes your maintenance calories, also called TDEE, and subtracts a calorie deficit based on your chosen weight loss goal.
What deficit should you choose?
- 250 calories/day = mild and slower weight loss
- 500 calories/day = common and moderate weight loss
- 750 calories/day = more aggressive weight loss
Is a bigger deficit always better?
No. A very large deficit can be harder to maintain and may not be suitable for everyone.
Important note
This calculator gives an estimate, not medical advice. Daily calorie needs vary depending on your health, body composition, and activity level.
