What is a Calorie Calculator?
A calorie calculator is a tool designed to help you understand how
many calories you need each day to maintain, gain, or lose weight.
Whether you're working toward a fitness goal, managing your health, or
adjusting your daily intake, using a reliable calorie calculator to
lose weight or gain weight can make all the difference.
This calculator uses your weight, height, age, activity level, and
goal to provide a customized calorie estimate. It can also function as
a calorie intake calculator, allowing you to plan meals and understand
how many calories you should eat in a day.
How a Calorie Calculator Works
Calorie calculators use formulas like the Mifflin-St Jeor or
Harris-Benedict equations to estimate your TDEE (Total Daily Energy
Expenditure). TDEE is the number of calories your body burns in a day
based on:
- Basal Metabolic Rate (BMR)
- Physical Activity Level (PAL)
A good TDEE calculator gives an accurate daily intake requirement
which can be further adjusted to create a calorie deficit or surplus,
depending on your goal.
Calorie Deficit: What Does It Mean?
A calorie deficit occurs when you consume fewer calories than your
body burns. It's essential for weight loss. Our calorie deficit
calculator (kg-based) helps you determine how much of a deficit is
required to shed weight over time safely and effectively.
Calories to kg Conversion:
- 1 kg of fat = approximately 7700 calories.
- To lose 1 kg, you need a 7700-calorie deficit over time.
-
For example, a calorie deficit calculator kg lets you see how
cutting 500 calories per day can help you lose roughly 0.5–1 kg per
week.
Using the Calorie Calculator for Weight Loss and Gain
Calorie Calculator to Lose Weight
If your goal is fat loss:
- Input your current weight, height, and age.
- Select an activity level (sedentary to very active).
- Choose "weight loss" as your goal.
-
The calculator will create a safe calorie deficit diet based on your
TDEE.
Calorie Calculator to Gain Weight
If your goal is weight gain:
- Follow the same steps, but choose "weight gain."
-
The calculator adds a calorie surplus to help you build lean muscle
or body mass.
Calorie Intake Calculator by Activity Level
This calorie intake calculator accounts for:
- Sedentary (little or no exercise)
- Lightly active (light exercise/sports 1–3 days/week)
- Moderately active (moderate exercise/sports 3–5 days/week)
- Very active (hard exercise 6–7 days/week)
- Extra active (very hard exercise & physical job)
Your daily calorie needs vary greatly depending on your movement,
making an accurate calorie calculator crucial.
Food Calorie Calculator – Know What You Eat
One of the most useful tools for health-conscious individuals is a
food calorie calculator. It helps you log meals and count calories,
ensuring you're staying within your goal.
For example:
- Calories in banana (medium-sized): ~89 calories
- Calories in boiled egg: ~78 calories
- Calories in rice (1 cup): ~200 calories
Tracking these through a calorie calculator app or using our free food
calorie calculator ensures you stay consistent.

Calorie Calculator Example
Let's say you're:
- 25 years old
- Weigh 70 kg
- Height: 170 cm

deficit)
Using a calorie deficit calculator, you can experiment with different
values to find what suits you.
