Bmi Weight Loss Calculator
Target BMI Calculator
The BMI Weight Loss Calculator is an easy-to-use health tool that helps you calculate your Body Mass Index (BMI) and set realistic weight loss goals.
It determines whether your weight is in a healthy range for your height — and helps you estimate how much weight you should lose (or gain) to reach your target BMI.
Whether you’re starting a fitness journey or tracking ongoing progress, this calculator gives you accurate health metrics to plan your weight management effectively.
💡 Understanding BMI (Body Mass Index)
BMI (Body Mass Index) is a number derived from your weight and height, used as an indicator of body fatness.
It’s calculated using this formula: BMI=Weight (kg)Height (m)2\text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}BMI=Height (m)2Weight (kg)
Or, in pounds and inches: BMI=Weight (lbs)×703Height (in)2\text{BMI} = \frac{\text{Weight (lbs)} \times 703}{\text{Height (in)}^2}BMI=Height (in)2Weight (lbs)×703
Your BMI places you in one of these categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
The BMI Weight Loss Calculator helps you find your current BMI, ideal BMI, and the weight difference required to reach your healthy range.
🧭 How the BMI Weight Loss Calculator Works
This calculator uses your:
- Current weight
- Height
- Target weight (optional)
- Gender & age (optional, for better accuracy)
Then it:
- Calculates your current BMI
- Estimates your ideal weight range
- Shows your weight loss or gain goal
- Suggests how much weight you need to lose to reach a healthy BMI
🧮 Example Calculation
Let’s say Maria is 5’6” tall (167.6 cm) and weighs 170 lbs (77.1 kg).
- She enters her height and current weight.
- The calculator computes: BMI=170×703662=27.4\text{BMI} = \frac{170 \times 703}{66^2} = 27.4BMI=662170×703=27.4 So, her BMI is 27.4, which falls in the Overweight category.
- To reach a healthy BMI of 24.9, Maria’s target weight should be: Weight=24.9×662703=155.8 lbs\text{Weight} = 24.9 \times \frac{66^2}{703} = 155.8 \text{ lbs}Weight=24.9×703662=155.8 lbs So she needs to lose about 14 pounds to reach a healthy BMI.
✅ Result:
Current BMI: 27.4 (Overweight)
Target BMI: 24.9
Target Weight: 155.8 lbs
Weight to Lose: 14.2 lbs
