Fitness & Health Calculators
Tools to help you stay fit and monitor your health
Body Mass Index (BMI) Calculator
Body Mass Index (BMI) is a simple calculation using a person’s height and weight. The formula is BMI = kg/m² where kg is a person’s weight in kilograms and m² is their height in meters squared.

Key Fitness Calculators Explained
1. Body Mass Index (BMI)
BMI helps assess whether you fall within a healthy weight range.
Formula: BMI = Weight (kg) / Height (m)^2
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5–24.9 | Normal weight |
| 25–29.9 | Overweight |
| 30 and above | Obese |
While BMI is easy to calculate, it doesn't consider muscle mass, bone density, or body composition.
2. Basal Metabolic Rate (BMR)
BMR estimates the number of calories your body burns at rest. Knowing your BMR can help you plan your diet and caloric intake more accurately.
Popular Equation: Mifflin-St Jeor
- Men: BMR = 10weight(kg) + 6.25height(cm) - 5*age + 5
- Women: BMR = 10weight(kg) + 6.25height(cm) - 5*age - 161
3. Calorie Burn Calculator
This tool helps you estimate calories burned during activities like running, cycling, or swimming.
Example: A 70kg person running for 30 minutes burns around 300 calories.
Use this Calories Burned Calculator for activity-specific data.
4. Body Fat Percentage Calculator
This is more precise than BMI in measuring fitness. Methods include:
- Skinfold calipers
- Bioelectrical impedance
- DEXA scans
Online calculators use measurements like waist, neck, and hip circumference to estimate fat percentage.
5. Target Heart Rate Calculator
Knowing your heart rate zones helps maximize cardio efficiency.
Formula: (220 - Age) * Desired Intensity (%)
Example: For a 30-year-old targeting 70% intensity:
- (220 - 30) * 0.70 = 133 bpm
Use this Target Heart Rate Calculator to personalize zones.
Practical Examples: Fitness in Action
Case Study: Sarah, a Busy Professional
Sarah is a 35-year-old marketing executive aiming to lose weight. By using:
- BMI Calculator, she realizes she’s in the overweight category.
- BMR Calculator, she learns she needs 1600 calories daily to maintain her current weight.
- Calorie Burn Calculator, she adds 30 minutes of brisk walking, burning 150 calories.
With real-time feedback, Sarah tailors her diet and workout without hiring a personal trainer.
Case Study: Mark, a Beginner Lifter
Mark wants to bulk up. He uses:
- Macronutrient Calculator to get the right balance of protein, carbs, and fats.
- BMR Calculator to know he needs 2800 calories/day to gain mass.
- Body Fat Calculator to ensure gains are lean muscle, not fat.
He avoids "dirty bulking" thanks to the precision of digital tools.
Comparing Tools: Pros & Cons
| Calculator Type | Pros | Cons |
| BMI | Easy, Fast | Doesn’t reflect muscle mass |
| BMR | Great for calorie planning | May not account for activity accurately |
| Body Fat % | More specific | Requires accurate measurement |
| Calorie Burn | Activity-based | Estimates can vary |
