1RM / Deadlift
Deadlift
Deadlift Calculator
Enter a deadlift set that locked out cleanly. Conventional, sumo, and trap-bar pulls are separate maxes even when the formulas look the same.
Enter a weight and at least one clean rep.
Deadlift estimate
117.5 kg
Median of seven formulas: 116.6 kg, rounded to 2.5 kg.
The formulas run from 112.5 to 119 kg.
Above 10 reps, endurance starts to limit the set. A set of 3–8 reps tracks max strength more closely.

Lock the rep out once
A deadlift rep starts on the floor and finishes with the knees and hips straight. Hitching the bar up the thighs, or bouncing it, adds a rep the formulas were not built to read. Straps and a mixed grip can add load too, so compare weeks that used the same setup.
A Romanian deadlift is a hinge from the hang, not a floor pull. Select it on its own.
Are conventional and sumo the same max?
No. Enter the stance you pulled and keep the other one separate.
Do hitching reps count?
No. Count a rep only when the bar moves once from the floor to a locked stand.
