Change one assumption at a time to see which inputs have the greatest effect on the estimate.
Worked example
The side-by-side output shows that formulas can disagree.
Limitations
Educational estimate only. This calculator does not diagnose any condition, provide medical advice, prescribe treatment, or replace a doctor or qualified healthcare professional. There is no single medically ideal weight, and these older formulas do not incorporate build, composition, disability, ethnicity, or individual health.
Review this educational estimate against current quotes, official information, and your own budget before making a financial decision.
