Enter the bone loss level and the healthy bone level into the Calculator. The calculator will evaluate the Bone Loss Percentage. 

Bone Loss Percentage Formula

BLP = BLL / HBL * 100


  • BLP is the Bone Loss Percentage (%)
  • BLL is the bone loss level
  • HBL is the healthy bone level

To calculate Bone Loss Percentage, divide the bone loss level by the health bone level, then multiply by 100.

How to Calculate Bone Loss Percentage?

The following steps outline how to calculate the Bone Loss Percentage.

  1. First, determine the bone loss level. 
  2. Next, determine the healthy bone level. 
  3. Next, gather the formula from above = BLP = BLL / HBL * 100.
  4. Finally, calculate the Bone Loss Percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

bone loss level = 40

healthy bone level = 75


What is bone loss and why is it significant?

Bone loss, or osteoporosis, refers to the decrease in bone density and strength. It is significant because it increases the risk of fractures, which can lead to decreased mobility and other health complications, especially in older adults.

What factors contribute to bone loss?

Several factors can contribute to bone loss, including aging, hormonal changes (especially in women post-menopause), lack of calcium and vitamin D, insufficient physical activity, and certain medications and medical conditions.

How can bone loss be prevented or treated?

Bone loss can be prevented or slowed through lifestyle changes such as maintaining a diet rich in calcium and vitamin D, engaging in regular weight-bearing and muscle-strengthening exercises, avoiding smoking and excessive alcohol consumption, and getting regular bone density screenings. Treatments may include medications, supplements, and lifestyle modifications.

Can the Bone Loss Percentage Calculator help in diagnosing osteoporosis?

While the Bone Loss Percentage Calculator can provide an estimate of bone loss, it is not a diagnostic tool. Diagnosing osteoporosis requires a medical evaluation, including a bone density test (DEXA scan) and a review of the patient’s medical history and risk factors by a healthcare professional.
