This calculator uses a formula that is optimized for calculcating your 1RM squat weight. It uses a composite of the Brzycki and Lander formulas and the National Strength and Conditioning Association (NSCA) squat coefficients. For a more accurate 1RM bench press weight or 1RM deadlift weight, use the 1RM Bench Press Calculator or the 1RM Deadlift Calculator. For an explanation of how the various 1RM formulas work and the differences between them, visit the 1RM Formulas page.

1RM calculators are typically accurate to within 5% of your actual 1RM weight for calculations using 10 reps or less.  The accuracy of the formulas diminshes past 10 reps, and calculators such as this one should not be relied upon at all past 20 reps.  Keep in mind that this calculator is not 100% accurate and is only intended to be a good starting point for exercise programs that use your 1RM.
