How to Use This Calculator
Using this carb consumption calculator is simple. Follow these steps:

Formula Used
The carb consumption calculator uses the following formula to estimate your daily carbohydrate needs:
Daily Carb Intake (grams) = (Weight × Activity Factor) + Goal Adjustment
Where:
- Weight is in kilograms
- Activity Factor is based on your activity level
- Goal Adjustment is based on your health objective
The activity factors are:
- Sedentary: 25 grams/kg
- Lightly active: 30 grams/kg
- Moderately active: 35 grams/kg
- Very active: 40 grams/kg
- Extra active: 45 grams/kg
The goal adjustments are:
- Lose weight: -200 grams
- Maintain weight: 0 grams
- Gain muscle: +200 grams
Worked Example
Let's calculate the daily carb intake for a 70 kg person who is moderately active and wants to maintain their weight.
- Weight = 70 kg
- Activity level = Moderately active (35 grams/kg)
- Goal = Maintain weight (0 grams)
Calculation:
Daily Carb Intake = (70 × 35) + 0 = 2450 grams
This person should consume approximately 2450 grams of carbohydrates per day to maintain their current weight.
