Health & Fitness Calculators

Free health & fitness calculators: BMI, calorie needs, ideal weight, pregnancy due date and age calculator.

Health numbers are reference points, not verdicts. BMI is a screening tool (muscular people often score “overweight” on it), calorie estimates are starting points, and ideal weight formulas disagree with each other on purpose — they were built for different populations.

These calculators show the formula, the source and the limitations of each result — informational, never a substitute for a professional who can see the whole picture.
