About this estimate The estimated 1RM is the average of three formulas (Epley, Brzycki, Lombardi). Estimates are most accurate for sets of 1–5 reps. Heavy deadlift singles carry injury risk — always work up conservatively and ensure your technique is sound.

Deadlift 1RM Calculator

The deadlift is one of the best overall indicators of total-body strength, involving the entire posterior chain. Estimating your 1RM from a working set lets you programme percentage-based training without the high injury risk of a maximal attempt.

Deadlift vs other lifts

Deadlift 1RM estimates tend to be slightly more accurate than bench press because the lift has a simpler movement pattern — a concentric pull from the floor — with less technique variance between individuals. However, grip strength, leverages, and bar path still introduce individual variation.

Warm-up for the deadlift

Unlike the squat and bench press, most deadlift warm-up schemes start at 50% of 1RM (not the empty bar) because the hip-hinge pattern is better grooved with meaningful resistance. Suggested sets: 50% for 5 reps, 65% for 3, 80% for 2, 90% for 1, then your working weight.

Frequently asked questions

Should I use conventional or sumo deadlift numbers?

Use whichever variation you primarily train. The formulas are stance-agnostic; they only require the weight lifted and reps performed. Your 1RM values will naturally differ between stances based on your biomechanics.

Why is my deadlift 1RM much higher than my squat?

This is common, especially early in training. The deadlift engages the entire posterior chain from a mechanically strong hip-hinge position. A 10–20% difference (deadlift higher) is typical; larger differences may indicate a lagging squat pattern rather than an unusually strong deadlift.
