Daily Carb Intake Calculator - Recommended Carbs Per Day
Calculate your recommended daily carbohydrate intake in grams from your total daily calories and desired carb percentage.

How Daily Carb Intake Is Calculated
Enter your total daily calorie target and choose what percentage of those calories should come from carbohydrates. The Dietary Guidelines for Americans recommend 45-65% of total calories from carbohydrates for most adults — this calculator lets you pick anywhere in (or outside) that range and converts it into grams, since carbohydrates provide 4 calories per gram.
If you don't know your daily calorie target, our Macro Calculator can estimate it from your age, weight, height, and activity level, along with a full protein/carb/fat split in one go. This tool is for when you just want a focused answer for carbohydrates alone.
Example
On a 2,000 calorie/day diet at the standard guideline midpoint of 50% carbs, that's (2,000 × 0.50) ÷ 4 = 250g of carbohydrates per day. A lower-carb approach at 30% would work out to 150g per day on the same calorie target.
Common Use Cases
- Setting a daily carbohydrate target for a tracking app like MyFitnessPal.
- Comparing how a lower-carb or higher-carb approach changes your gram target.
- Planning meals around a specific carbohydrate budget.
- Pairing with a protein or fat target to round out a full macro plan.
FAQs
What percentage of calories should come from carbs?
Standard dietary guidelines recommend 45-65% of total calories from carbohydrates for most healthy adults. Athletes with high training volume often sit at the higher end, while people following lower-carb or ketogenic approaches intentionally go well below this range.
How is this different from the Macro Calculator?
The Macro Calculator estimates your full daily calorie target from your stats and activity level, then splits it into protein, carbs, and fat all at once. This calculator is a focused, single-purpose tool for when you already know your calorie target (or want to enter one directly) and just want the carb number.
Should I consult a professional before changing my carb intake significantly?
Yes — this tool is for general planning only. If you have diabetes, a metabolic condition, or are making a major dietary change, talk to a doctor or registered dietitian first.
