What is the Carbohydrate Calculator?

The Carbohydrate Calculator is a tool designed to estimate daily carbohydrate intake based on weight, height, age, activity level, and fitness goals. Carbohydrates play a key role in energy production, and this calculator helps optimize intake for weight maintenance, muscle gain, or performance enhancement.

Carbohydrate Calculation Formula

Basal Metabolic Rate (BMR) - Mifflin-St Jeor Formula:

For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Daily Caloric Needs:

Calories = BMR × Activity Multiplier × Goal Adjustment

Carbohydrate Needs:

Daily Carbs (g) = (Calories × Carb Ratio) ÷ 4

FAQs

How many carbs should I eat daily?

Your carb needs depend on activity level and goals. The calculator adjusts intake for maintenance, fat loss, or muscle gain.

Are low-carb diets effective?

Low-carb diets can aid in fat loss, but performance athletes may require higher carbohydrate intake for optimal energy.

How does exercise intensity affect carb needs?

Higher intensity workouts require more carbs for energy, while low-intensity activities rely more on fats.

Can I use this calculator for a ketogenic diet?

This calculator is optimized for general carbohydrate needs. A ketogenic diet typically restricts carbs to under 50g per day.
