Weight-Cut Calculator
Plan a safe weight cut from your current walking weight to your fight-weight target. Estimates the fat-loss vs water-cut split, fluid loading volumes, and rehydration targets. Not medical advice — use under a coach who has supervised real cuts.
Inputs
Read the methodology
This calculator uses the methodology described in our full weight-cut guide: phase-based fat then water, never the reverse; gender- and body-fat-adjusted ceilings; oral rehydration protocol after the scale. The numbers are conservative coach defaults — they replace neither a real coach nor a real cut-history conversation.
