Deadlift 1RM Calculator

The deadlift is often your strongest lift and the ultimate test of total-body strength. Estimate your deadlift 1RM safely from a moderate set rather than grinding out a risky max attempt. Enter your most recent working set below.

Estimating Your Deadlift Max

Perform a set of deadlifts with a weight you can handle for 3-6 reps with good form (no rounding of the lower back). Enter the weight and reps completed into the calculator. Deadlift 1RM estimates are slightly less accurate than for other lifts because fatigue affects grip and form quickly at higher reps. Keep test sets at 5 reps or fewer for the best accuracy.

Deadlift Strength Standards

For men: beginner (1x body weight), intermediate (1.5x BW), advanced (2.5x BW), elite (3x+ BW). For women: beginner (0.75x BW), intermediate (1.25x BW), advanced (2x BW), elite (2.5x+ BW). These apply to conventional deadlift. Sumo deadlift numbers are typically similar, though individual leverages may favor one style.

Frequently Asked Questions

Conventional or sumo: which deadlift should I calculate?
Calculate whichever style you train with most. Both are valid competition lifts. If you train both, calculate each separately. Most people find one style is naturally stronger due to their body proportions (longer torso favors sumo, longer arms favor conventional).
How can I improve my deadlift 1RM?
Focus on progressive overload with sets of 3-5 reps, strengthen your weak points (common ones: off the floor = quad weakness, at lockout = glute/back weakness, grip = forearm weakness), and ensure adequate recovery between deadlift sessions (48-72 hours minimum). Deadlift responds well to lower frequency but higher intensity.
