Fiber is an essential nutrient that plays a key role in maintaining a healthy digestive system, supporting weight loss, and reducing the risk of chronic diseases. But how much fiber do you need daily? Our Daily Fiber Intake Calculator helps you determine the exact amount of fiber required based on your age, gender, and dietary needs. Whether you want to improve digestion, lose weight, or follow NHS fiber recommendations, this calculator makes it easy to achieve your daily fiber goals.

How Much Fiber Do You Need Per Day?

The recommended daily fiber intake varies based on factors such as age, gender, and health goals. According to general guidelines:

Age GroupRecommended Fiber Intake (Grams/Day)
Children (1-3 years)19g
Children (4-8 years)25g
Males (9-13 years)31g
Males (14-50 years)38g
Males (51+ years)30g

Fiber Intake Calculation Formula

The general formula to calculate fiber intake follows:

Daily Fiber Intake (g) = Age Factor + Gender Factor + Health Goal Factor

Where:

  • Age Factor is based on the recommended dietary guidelines.
  • Gender Factor adjusts fiber needs for males and females.
  • Health Goal Factor increases fiber intake for weight loss or digestion improvements.

For example, an adult female (25 years old) would need 25g of fiber daily, while an adult male (30 years old) would need 38g of fiber daily.
