Deadlift 1RM Calculator — estimate your deadlift 1RM (2026)
The deadlift lets you move more weight than any other lift, which makes your deadlift one-rep max the truest test of total-body strength. Enter a recent deadlift set and this deadlift calculator estimates your 1RM using seven proven formulas.
What is a good deadlift?
Deadlift standards run higher than other lifts: about 2× bodyweight is a common intermediate mark for men and 2.5× is advanced, while pulling your bodyweight is an early milestone. Women deadlifting 1.5–2× bodyweight are strong.
Why low reps matter for the deadlift
Grip and lower-back fatigue make high-rep deadlift sets drop off fast, so a set of 8–10 underestimates your max. For the most accurate deadlift 1RM, use a heavy set of 1–4 clean reps with consistent form, conventional or sumo.
Deadlift calculator — frequently asked questions
How much should I be able to deadlift?
Pulling 2× bodyweight is a strong intermediate benchmark for men, with 2.5× bodyweight marking advanced lifters. For women, 1.5–2× bodyweight is impressive.
Is a 1RM calculator accurate for deadlifts?
It is most accurate at low reps. Because grip and back fatigue cap deadlift rep performance, estimate from a heavy set of 1–4 reps rather than a high-rep burnout set.
What is a one-rep max (1RM)?
Your one-rep max is the heaviest weight you can lift for a single repetition with good form. It is the standard measure of maximal strength and the reference point for setting training percentages.
How many reps should I use for the best estimate?
Use a challenging set you took close to failure at 2–6 reps. That range balances accuracy and safety — heavy enough to predict your max well, light enough to perform without undue risk.
Is it safe to test my true one-rep max?
Maximal singles carry more injury risk and need a thorough warm-up and ideally a spotter. For most lifters, estimating your 1RM with a calculator is safer and accurate enough for programming.
