What is a carbohydrate calculator?

A carbohydrate calculator estimates daily carb intake from calories and macro targets.

How are carbs calculated?

Carbs are calculated from remaining calories after protein and fat: carbs = remaining calories / 4.

How many calories are in carbohydrates?

One gram of carbohydrate contains 4 calories.

Carbohydrates vs protein and fat

Protein and carbs each provide 4 calories per gram. Fat provides 9 calories per gram.

When should you adjust carbs?

Carbs often change based on goals, activity level, and calorie target.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
