How many carbs should I eat per day?

For most people, 45–65% of total calories from carbohydrate is a commonly cited moderate range, though needs vary widely based on activity level, goals, and personal preference.

What counts as a low-carb diet?

Diets under about 25% of calories from carbohydrate (and often much lower) are generally considered low-carb, with very low intakes associated with ketogenic approaches.

Does carb intake affect weight loss?

What matters most for weight loss is total calorie balance; carb intake mainly affects which foods fit your calorie and macro targets and how you may feel on different eating styles.

How it works

The calculator takes the percentage-of-calories range for your chosen carbohydrate level and converts it into grams, using the standard conversion of 4 calories per gram of carbohydrate.

Formula & methodology

Carbs (g) = (total calories × carb percentage) ÷ 4.

Worked example

On 2,200 calories with a Moderate carb level (45–65%), that works out to roughly 248–358 g of carbohydrate per day.
