How these calculators work
Every number comes from a published rule, not a guess. The high school tools use the NFHS model that most state associations follow: a hydration test first, then a body fat test that sets your minimum weight, then a limit on how fast you may lose weight, about 1.5% of your body weight per week. Where a state does something different, such as its own hydration limit or growth allowance date, the tool uses that state's handbook. The college tool uses the NCAA weight management rules, and the combat sports tools use the limits and weigh-in times each governing body publishes.
Each calculator page explains the formula, works through a full example and links the official source, so you can check the math yourself or show it to your coach.
What the calculators will not do
They will not tell you to cut faster than the rules allow, and they never suggest dehydrating to make weight. If a result says your goal is too aggressive, the safer move is a later weigh-in, a higher class, or a slower plan. The tools also do not replace your official certification: your school or state runs the real test and its number is the one that counts.
