Goal Weight for Target BMI Calculator

About this calculator

Body Mass Index is calculated as weight divided by height squared, so working the formula in reverse — weight equals target BMI times height squared — gives the exact body weight needed to land on a chosen BMI value at a fixed height. It's the same relationship as a standard BMI calculator, just solved for the opposite variable.

This calculator takes your height and a target BMI value and returns the weight that would produce it, which is useful for setting a concrete weight goal tied to a BMI category boundary (such as the threshold between “overweight” and “normal” ranges) rather than working with an abstract BMI number that's harder to picture on a scale. It's a planning tool, not a substitute for a doctor's assessment of a healthy weight for your individual situation.
