Calories And Macro Calculator
Carbohydrates will make up the remaining calories. Protein and fat percentages must total less than 100%.
Understanding how many calories and macronutrients your body needs every day is an important part of maintaining a balanced diet and achieving your fitness goals. Whether you're trying to lose weight, build muscle, maintain your current weight, or improve your eating habits, knowing your estimated daily calorie and macro requirements can help you make more informed nutrition decisions.
Our Calories and Macro Calculator is a free online tool designed to estimate your daily calorie needs and calculate personalized protein, carbohydrate, and fat targets based on your age, biological sex, weight, height, activity level, and fitness goals.
Instead of manually calculating multiple nutrition formulas, you can enter your personal information and receive estimated daily nutrition targets within seconds.
The calculator uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR). It then applies an activity multiplier to calculate your approximate Total Daily Energy Expenditure (TDEE), commonly called maintenance calories.
Depending on your selected fitness goal, the calculator adjusts your daily calorie target for weight loss, weight maintenance, or weight gain.
You can also customize your protein and fat percentages, while carbohydrates automatically receive the remaining calories.
For example, if you select 25% protein and 25% fat, the calculator assigns the remaining 50% of your calories to carbohydrates.
Additionally, the calculator displays a visual macronutrient distribution chart to help you understand how your daily calories are divided among protein, carbohydrates, and fats.
Whether you're starting a fitness program, tracking your macros, or planning a structured eating routine, this daily calorie and macro calculator provides a convenient starting point.
Important: The results are estimates for general nutrition planning, not medical prescriptions. Actual calorie and macronutrient needs vary depending on body composition, metabolism, physical activity, health conditions, and other individual factors.
What Is a Calories and Macro Calculator?
A Calories and Macro Calculator is an online nutrition tool that estimates your daily energy requirements and divides those calories among the three main energy-providing macronutrients.
These macronutrients are protein, carbohydrates, and dietary fat.
Each nutrient plays an important role in maintaining normal body functions.
Protein supports muscle maintenance, tissue repair, and the production of essential biological compounds.
Carbohydrates provide energy for everyday activities, physical exercise, and other bodily functions.
Dietary fat supports cell structure, nutrient absorption, and several important physiological processes.
Our calculator uses your physical information and selected activity level to estimate how many calories your body may need each day.
It then adjusts that estimate according to your fitness goal.
Finally, it calculates daily macronutrient targets based on your chosen protein and fat percentages.
The calculator provides several useful measurements:
- Estimated Daily Calories: Your calorie target based on your selected fitness goal.
- Basal Metabolic Rate (BMR): Estimated energy expenditure at rest.
- Maintenance Calories (TDEE): Estimated total daily energy expenditure.
- Protein: Your daily protein target in grams.
- Carbohydrates: Your calculated daily carbohydrate allowance.
- Fat: Your estimated daily dietary fat target.
- Protein Calories: Calories allocated to protein.
- Carbohydrate Calories: Calories allocated to carbohydrates.
- Fat Calories: Calories allocated to dietary fat.
- Macro Distribution Chart: A visual representation of your daily macronutrient percentages.
These results can help you organize your food intake and compare different nutrition strategies.
How to Use the Calories and Macro Calculator
Our free Calories and Macro Calculator is designed to make nutrition planning simple.
Follow these steps to calculate your estimated daily calories and macros.
Step 1: Enter Your Age
Start by entering your age in years.
The calculator accepts adults aged 18 to 120 years.
For example:
Age = 30 years
Age is included in the Mifflin-St Jeor equation because resting energy expenditure often changes throughout adulthood.
Enter your current age for a more relevant estimate.
Step 2: Select Your Biological Sex
Next, choose the sex-based metabolic equation.
The calculator provides two options:
Male: Uses the male Mifflin-St Jeor equation.
Female: Uses the female Mifflin-St Jeor equation.
These equations contain different constants.
Your selection influences your estimated BMR and maintenance calories.
Because metabolic equations are population-based estimates, they may not accurately represent every individual's physiology.
Step 3: Enter Your Current Weight
Enter your body weight.
The calculator supports:
Kilograms (kg)
Pounds (lb)
For example:
Weight = 75 kg
Or:
Weight = 165 lb
If you select pounds, the calculator automatically converts your weight into kilograms.
The calculator accepts weights equivalent to approximately 20–500 kilograms.
Your weight is used when estimating resting energy expenditure.
Step 4: Enter Your Height
Next, enter your height.
The calculator supports two measurement units:
Centimeters (cm)
Inches (in)
For example:
Height = 175 cm
Alternatively:
Height = 69 inches
If you're 5 feet 9 inches tall, enter 69 when using inches.
The calculator automatically converts inches into centimeters.
The supported height range is equivalent to 100–250 centimeters.
Step 5: Choose Your Activity Level
Your activity level helps estimate your total daily energy expenditure.
The calculator provides five activity categories.
| Activity Level | Multiplier | Description |
|---|---|---|
| Sedentary | 1.2 | Little or no exercise |
| Lightly Active | 1.375 | Exercise 1–3 days per week |
| Moderately Active | 1.55 | Exercise 3–5 days per week |
| Very Active | 1.725 | Exercise 6–7 days per week |
| Extra Active | 1.9 | Intense training or physically demanding work |
For example, someone exercising four days weekly might initially select Moderately Active.
However, exercise frequency alone does not determine calorie expenditure.
Workout intensity, occupation, walking, and other daily activities also affect energy requirements.
Step 6: Select Your Fitness Goal
The calculator offers three fitness goals.
Weight Loss: Applies a 15% calorie deficit.
Maintain Weight: Uses estimated maintenance calories without adjustment.
Weight Gain / Muscle Building: Applies a 10% calorie surplus.
For example, suppose your estimated maintenance calories are 2,500.
Weight Loss = 2,125 calories
Maintain Weight = 2,500 calories
Weight Gain = 2,750 calories
These are general starting estimates rather than guaranteed weight-change outcomes.
Step 7: Choose Your Protein Percentage
Next, select the percentage of daily calories you want to obtain from protein.
The calculator provides four options:
20%: Moderate Protein
25%: Balanced
30%: Higher Protein
35%: High Protein
The default setting is 25%.
For example:
Daily Calories = 2,000
Protein Percentage = 25%
Protein Calories = 2,000 × 0.25
Protein Calories = 500
Protein Grams = 500 ÷ 4
Protein Target = 125 grams
Step 8: Choose Your Fat Percentage
Next, select your preferred dietary fat percentage.
The calculator provides four options:
20%: Lower Fat
25%: Balanced
30%: Moderate Fat
35%: Higher Fat
The default setting is 25%.
For example:
Daily Calories = 2,000
Fat Percentage = 25%
Fat Calories = 2,000 × 0.25
Fat Calories = 500
Fat Grams = 500 ÷ 9
Fat Target ≈ 56 grams
Step 9: Understand the Carbohydrate Calculation
The calculator automatically assigns the remaining calories to carbohydrates.
For example:
Protein = 25%
Fat = 25%
Carbohydrates = 100 − 25 − 25
Carbohydrates = 50%
You don't need to enter a separate carbohydrate percentage.
This ensures your selected macro distribution totals 100%.
Step 10: Click Calculate
After entering your information, click Calculate.
The calculator displays your estimated daily nutrition targets.
These include calories, BMR, TDEE, protein, carbohydrates, fat, and their calorie contributions.
Step 11: Review Your Macro Distribution Chart
The calculator includes a visual chart showing the percentage of daily calories assigned to each macronutrient.
For example:
Protein = 25%
Carbohydrates = 50%
Fat = 25%
The chart displays these proportions using separate colored sections.
Step 12: Reset the Calculator
To perform another calculation, click Reset.
This clears your previous entries and restores the original settings.
Calories and Macro Calculator Formula
Our calculator uses the Mifflin-St Jeor equation to estimate resting energy expenditure.
It then calculates maintenance calories and adjusts the result according to your selected fitness goal.
Finally, it distributes calories among protein, carbohydrates, and fats.
1. Basal Metabolic Rate Formula
For males:
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) + 5
For females:
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) − 161
BMR estimates how many calories your body uses at rest.
For example, consider a 30-year-old man weighing 75 kg and measuring 175 cm tall.
BMR = (10 × 75) + (6.25 × 175) − (5 × 30) + 5
BMR = 750 + 1,093.75 − 150 + 5
BMR = 1,698.75 calories/day
2. Maintenance Calories Formula
Maintenance calories are calculated using:
TDEE = BMR × Activity Multiplier
For example:
BMR = 1,698.75
Activity Multiplier = 1.55
TDEE = 1,698.75 × 1.55
TDEE ≈ 2,633 calories/day
This is your estimated maintenance calorie requirement.
3. Weight Loss Calorie Formula
For weight loss, the calculator applies a 15% reduction.
Weight Loss Calories = TDEE × 0.85
For example:
TDEE = 2,500
Weight Loss Calories = 2,500 × 0.85
Daily Target = 2,125 calories
4. Weight Gain Calorie Formula
For weight gain, the calculator applies a 10% increase.
Weight Gain Calories = TDEE × 1.10
For example:
TDEE = 2,500
Weight Gain Calories = 2,500 × 1.10
Daily Target = 2,750 calories
5. Protein Calculation Formula
Protein provides approximately four calories per gram.
Protein Calories = Daily Calories × Protein Percentage ÷ 100
Then:
Protein Grams = Protein Calories ÷ 4
For example:
Daily Calories = 2,400
Protein Percentage = 25%
Protein Calories = 600
Protein Grams = 600 ÷ 4
Protein = 150 grams
6. Fat Calculation Formula
Fat provides approximately nine calories per gram.
Fat Calories = Daily Calories × Fat Percentage ÷ 100
Then:
Fat Grams = Fat Calories ÷ 9
For example:
Daily Calories = 2,400
Fat Percentage = 25%
Fat Calories = 600
Fat Grams = 600 ÷ 9
Fat ≈ 67 grams
7. Carbohydrate Calculation Formula
The calculator allocates the remaining calories to carbohydrates.
Carbohydrate Calories = Daily Calories − Protein Calories − Fat Calories
Then:
Carbohydrate Grams = Carbohydrate Calories ÷ 4
For example:
Daily Calories = 2,400
Protein Calories = 600
Fat Calories = 600
Carbohydrate Calories = 2,400 − 600 − 600
Carbohydrate Calories = 1,200
Carbohydrate Grams = 1,200 ÷ 4
Carbohydrates = 300 grams
Example: Calculate Daily Calories and Macros for Weight Loss
Let's calculate a complete nutrition estimate using a practical example.
Suppose someone enters the following information:
Age: 30 years
Biological Sex: Male
Weight: 75 kg
Height: 175 cm
Activity Level: Moderately Active
Fitness Goal: Weight Loss
Protein Percentage: 25%
Fat Percentage: 25%
Step 1: Calculate BMR
BMR = (10 × 75) + (6.25 × 175) − (5 × 30) + 5
BMR = 1,698.75 calories
Step 2: Calculate TDEE
TDEE = 1,698.75 × 1.55
TDEE = 2,633.06
Maintenance Calories ≈ 2,633 kcal
Step 3: Calculate Weight Loss Calories
Daily Calories = 2,633.06 × 0.85
Daily Calories = 2,238.10
Daily Calorie Target ≈ 2,238 kcal
Step 4: Calculate Protein
Protein Calories = 2,238.10 × 0.25
Protein Calories = 559.53
Protein Grams = 559.53 ÷ 4
Protein Grams ≈ 139.88
Protein Target ≈ 140 grams
Step 5: Calculate Fat
Fat Calories = 2,238.10 × 0.25
Fat Calories = 559.53
Fat Grams = 559.53 ÷ 9
Fat Grams ≈ 62.17
Fat Target ≈ 62 grams
Step 6: Calculate Carbohydrates
Carbohydrate Calories = 2,238.10 − 559.53 − 559.53
Carbohydrate Calories ≈ 1,119.05
Carbohydrate Grams = 1,119.05 ÷ 4
Carbohydrate Grams ≈ 279.76
Carbohydrate Target ≈ 280 grams
Final Calculator Results
| Measurement | Estimated Result |
|---|---|
| Daily Calories | 2,238 kcal |
| BMR | 1,699 kcal |
| Maintenance Calories (TDEE) | 2,633 kcal |
| Protein | 140 g |
| Carbohydrates | 280 g |
| Fat | 62 g |
| Protein Calories | 560 kcal |
| Carbohydrate Calories | 1,119 kcal |
| Fat Calories | 560 kcal |
These values provide an estimated starting point for daily nutrition planning.
Because the calculator rounds displayed values, small differences may occur when recalculating calories from the rounded gram amounts.
What Are Macronutrients?
Macronutrients are nutrients your body needs in relatively large quantities.
The three main energy-providing macronutrients are protein, carbohydrates, and fats.
Each contributes energy and supports essential functions.
Protein
Protein supports muscle maintenance, tissue repair, enzyme production, and immune function.
Common protein sources include poultry, fish, eggs, dairy products, beans, lentils, and tofu.
Protein provides approximately four calories per gram.
Carbohydrates
Carbohydrates are an important energy source.
They help fuel everyday activities and physical exercise.
Foods containing carbohydrates include rice, oats, potatoes, fruits, vegetables, whole grains, and legumes.
Carbohydrates provide approximately four calories per gram under the calculator's simplified energy conversion.
Dietary Fat
Dietary fat supports cell structure, nutrient absorption, and several physiological processes.
Common sources include nuts, seeds, olive oil, avocados, and fatty fish.
Fat provides approximately nine calories per gram.
How Many Calories Should You Eat Per Day?
Daily calorie requirements vary according to age, weight, height, activity level, body composition, and health.
Your body uses energy for essential biological functions, movement, digestion, and exercise.
Our calculator estimates your daily needs by calculating BMR and applying an activity multiplier.
For example:
BMR = 1,700 calories
Activity Multiplier = 1.55
TDEE = 1,700 × 1.55
Estimated Maintenance Calories = 2,635 per day
This is a starting estimate rather than an exact measurement.
Actual maintenance calories may differ.
What Is the Best Macro Ratio?
There is no single macro ratio that works best for everyone.
The appropriate distribution depends on activity, dietary preferences, health, and fitness goals.
For general adult nutrition, commonly referenced Acceptable Macronutrient Distribution Ranges include:
| Macronutrient | General Adult Range |
|---|---|
| Protein | 10–35% |
| Carbohydrates | 45–65% |
| Fat | 20–35% |
These ranges provide general dietary guidance rather than personalized requirements.
Our calculator allows protein and fat percentages between 20% and 35%.
Carbohydrates automatically receive the remaining calories.
For example:
Protein = 25%
Fat = 25%
Carbohydrates = 50%
This produces a 25/50/25 macro distribution.
However, the calculator does not independently determine whether the resulting gram targets meet your specific nutritional needs.
Calories and Macro Calculator for Weight Loss
If you're trying to lose weight, understanding your estimated calorie needs can help you create an appropriate energy deficit.
Weight loss generally occurs when calorie intake remains below energy expenditure over time.
Our calculator applies a fixed 15% calorie reduction when you select Weight Loss.
For example:
Maintenance Calories = 2,600
Weight Loss Calories = 2,600 × 0.85
Daily Target = 2,210 calories
The calculator then distributes these calories according to your selected protein and fat percentages.
The remaining calories are allocated to carbohydrates.
However, a 15% deficit may not be appropriate for everyone.
People with low energy requirements, certain medical conditions, or specialized nutritional needs may require individualized guidance.
Why Is Protein Important During Weight Loss?
Protein supports muscle maintenance and tissue repair.
During weight loss, adequate protein intake may help preserve lean body mass, particularly when combined with resistance training.
Protein may also contribute to fullness.
However, protein alone does not guarantee fat loss.
Overall energy balance, dietary quality, physical activity, and individual circumstances also matter.
Our calculator allows you to select protein percentages up to 35%.
This can help you compare different protein allocations within your calorie target.
Calories and Macro Calculator for Muscle Gain
Building muscle generally requires resistance training, sufficient protein, adequate energy intake, and recovery.
Our calculator applies a 10% calorie surplus when you select Weight Gain / Muscle Building.
For example:
Maintenance Calories = 2,800
Calorie Surplus = 10%
Daily Target = 2,800 × 1.10
Daily Calories = 3,080 kcal
You can then choose your preferred protein and fat percentages.
For example:
Protein = 30%
Fat = 25%
Carbohydrates = 45%
The calculator converts these percentages into daily gram targets.
However, consuming additional calories does not guarantee that all gained weight will consist of muscle.
Training experience, exercise programming, and recovery also influence results.
Calories and Macro Calculator for Weight Maintenance
If your goal is to maintain your current body weight, select Maintain Weight.
The calculator uses estimated maintenance calories without applying a deficit or surplus.
For example:
BMR = 1,650 calories
Activity Multiplier = 1.55
TDEE = 1,650 × 1.55
Daily Target ≈ 2,558 calories
Your selected protein and fat percentages determine the macronutrient distribution.
This allows you to explore different dietary approaches while maintaining the same estimated calorie target.
How Much Protein Do You Need Daily?
Protein requirements vary depending on body weight, age, physical activity, and health.
For many healthy adults, the general Recommended Dietary Allowance is approximately 0.8 grams per kilogram of body weight daily.
People participating in regular resistance training may choose higher protein intakes.
Our calculator determines protein using a percentage of total calories rather than directly using body weight.
For example:
Daily Calories = 2,500
Protein Percentage = 25%
Protein Calories = 625
Protein Grams = 625 ÷ 4
Protein Target ≈ 156 grams
Whether this amount is appropriate depends on individual needs.
Why Are Carbohydrates Important?
Carbohydrates provide energy for daily activities and exercise.
They also help replenish glycogen stores used during physical activity.
Carbohydrate-containing foods can provide fiber, vitamins, and minerals.
Examples include fruits, vegetables, oats, rice, potatoes, and legumes.
Our calculator automatically allocates remaining calories to carbohydrates.
For example:
Daily Calories = 2,500
Protein = 25%
Fat = 25%
Carbohydrates = 50%
Carbohydrate Calories = 1,250
Carbohydrate Grams = 1,250 ÷ 4
Carbohydrates = 312.5 grams
Why Is Dietary Fat Important?
Dietary fat supports essential physiological functions.
It contributes to cell structure, nutrient absorption, and the supply of essential fatty acids.
Our calculator allows you to choose fat percentages between 20% and 35%.
For example:
Daily Calories = 2,500
Fat Percentage = 30%
Fat Calories = 750
Fat Grams = 750 ÷ 9
Fat ≈ 83 grams
The type of dietary fat also matters.
Foods containing unsaturated fats, such as nuts, seeds, olive oil, and fatty fish, can contribute to balanced nutrition.
Understanding Your Macro Distribution Chart
One useful feature of our Calories and Macro Calculator is its visual macro distribution chart.
The chart shows how your daily calories are divided among protein, carbohydrates, and fats.
For example:
Protein = 25%
Carbohydrates = 50%
Fat = 25%
The chart displays three sections representing these percentages.
This makes it easier to understand your selected macronutrient allocation.
The percentages represent calorie contributions rather than gram amounts.

How Accurate Is the Calories and Macro Calculator?
Our calculator uses the Mifflin-St Jeor equation to estimate resting energy expenditure.
It then applies an activity multiplier to estimate maintenance calories.
Although these are commonly used methods, they cannot determine exact energy requirements.
Actual calorie needs vary depending on muscle mass, genetics, physical activity, health conditions, and other factors.
The calculator also uses fixed calorie adjustments:
Weight Loss = 15% deficit
Weight Maintenance = No adjustment
Weight Gain = 10% surplus
These adjustments may not be appropriate for every individual.
Additionally, the calculator calculates protein and fat using selected percentages rather than independently determining body-weight-based nutritional requirements.
It also does not establish a medically appropriate minimum calorie intake.
Therefore, results should be treated as planning estimates rather than medical prescriptions.
Common Mistakes When Calculating Calories and Macros
Several mistakes can affect your results.
Choosing an Incorrect Activity Level
Overestimating activity may produce an inflated calorie target.
Entering the Wrong Measurement Unit
Make sure your height and weight values match the selected units.
Assuming More Protein Is Always Better
Protein requirements vary, and higher intake is not automatically necessary.
Ignoring Carbohydrates
Carbohydrates contribute energy and can support physical activity.
Choosing an Excessive Calorie Deficit
A calorie deficit may be inappropriate if it makes meeting nutritional needs difficult.
Focusing Only on Macronutrients
Meeting macro targets does not guarantee adequate vitamins, minerals, or fiber.
Treating Calculator Results as Exact
Metabolic equations provide estimates.
Actual requirements may change over time.
Tips for Following Your Daily Calorie and Macro Targets
