Question
Why divide by 4?
Carbohydrates contain about 4 calories per gram, so calorie targets from carbs are divided by 4 to estimate grams.

This carbohydrate calculator helps you estimate how many grams of carbohydrates fit within a daily calorie target based on the percentage of calories you want to allocate to carbs. It is useful for endurance fueling, macro planning, meal prep, cutting and bulking phases, and translating broad nutrition targets into concrete daily numbers.
Formula and method
The calculator multiplies total daily calories by the chosen carbohydrate percentage to estimate calories from carbohydrates, then divides by 4 calories per gram to estimate carbohydrate grams.
Example
If someone eats 2,200 calories per day and wants 45% of calories from carbohydrates, the calculator can estimate carbohydrate calories, total carb grams, a simple per-meal split, and the remaining calories for other macros.
