Weight Cutting Calculator for Fighters & Wrestlers

Most weight cutting advice is written for pro fighters with a full fight camp and a nutritionist on payroll. You’re cutting for a tournament on Saturday with a day job and a weigh-in format nobody explains until you’re standing in line at the scale. This calculator fixes that.

This tool is for adults only.

Water cutting is banned in most scholastic and youth divisions for good reason: it's dangerous for developing athletes and it doesn't help you win. Compete at your natural weight, eat well, and get strong. The cut game can wait.
