How to Use This BMI & Calorie Calculator
This tool gives you a quick snapshot of where you currently stand. Enter your age, height, weight, gender and how active you are on a typical week. When you hit “Calculate Results”, we estimate:
- Your Body Mass Index (BMI), a basic ratio of weight to height.
- Your daily calorie needs to roughly maintain your current weight.
- Two calorie targets for gradual and faster weight loss.
These numbers are estimates, not strict rules. Use them as a starting point for conversations with your doctor, dietitian, or trainer – especially if you have any existing medical conditions.
What Your BMI Result Really Means
BMI is widely used because it’s quick to calculate, but it has important limitations. It does not distinguish between muscle, fat and bone, and it can be misleading for athletes, older adults, or people with certain health conditions.
Think of your BMI as a conversation starter, not a final verdict. If your result falls outside the “normal” range, that’s simply a signal to look more closely at your lifestyle, nutrition, movement and overall health with a qualified professional.

Quick FAQ
Is this calculator only for people in the United States?
No. Anyone can use it, but WordMitr focuses on everyday life in the US, so examples in our articles may use American food portions, work patterns and lifestyle habits.
How accurate are the calorie numbers?
Calorie needs vary from person to person. The equation used here is a widely accepted estimate for adults, but your actual needs can be higher or lower. Treat the result as a helpful benchmark, not a strict limit.
What should I read next after using this tool?
After checking your BMI, consider exploring slow, sustainable changes: slightly more movement, better sleep and small food swaps. You can also bookmark this page and re-check your numbers in a few weeks to see how your progress looks.
