Max Bench Press Calculator
- Calculate Your One Rep Max (1RM)
The calculator below can be used to determine your approximate one
repetition
maximum (1RM) weight for the bench press or other exercises. Enter the
weight used (in pounds or kilograms) and the number of reps performed
(≤20)
and press the Calculate button.
This calculator is intended primarily for 1RM bench press calculations
and
uses a composite of the
Brzycki, Epley, Wathan and Mayhew formulas, but it
can be used for other exercises as well. For a more accurate 1RM squat
weight
or 1RM deadlift weight, use the
1RM Squat
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.
