Health, fitness and clinical calculators with standard formulas — body composition, calories, blood pressure, lipid panels, cardiac scores (CHA₂DS₂-VASc, HEART, TIMI), kidney/liver function (MELD, Child-Pugh), pregnancy and more.

Formula & example

The calculator computes Neck Disability Index from parameters:

Pain intensity (0–5)
Personal care (0–5)
Lifting (0–5)
Reading (0–5)
Headaches (0–5)
Concentration (0–5)
Work (0–5)
Driving (0–5)
Sleeping (0–5)
Recreation (0–5)

Example 1

Pain intensity (0–5) = 2, Personal care (0–5) = 1, Lifting (0–5) = 2, Reading (0–5) = 1, Headaches (0–5) = 2, Concentration (0–5) = 1, Work (0–5) = 1, Driving (0–5) = 2, Sleeping (0–5) = 1, Recreation (0–5) = 2

→ Neck Disability Index: 15

Example 2 (×1.5)

Pain intensity (0–5) = 3, Personal care (0–5) = 1.5, Lifting (0–5) = 3, Reading (0–5) = 1.5, Headaches (0–5) = 3, Concentration (0–5) = 1.5, Work (0–5) = 1.5, Driving (0–5) = 3, Sleeping (0–5) = 1.5, Recreation (0–5) = 3

→ Neck Disability Index: 22.5

FAQ

How is BMI calculated?

BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.

Is BMI accurate for everyone?

No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.

What are the BMI categories?

Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.

What is a better measure than BMI?

Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
