Free deadlift max calculator to estimate your barbell deadlift one-rep max from a submaximal set. Enter weight and reps, choose Epley, Brzycki, or Lombardi, and get an estimated deadlift 1RM plus percentage loads. Browse our fitness & lifestyle calculators or compare with the one rep max calculator for any lift.

Use a crisp set with solid positions off the floor—avoid grinding reps with a rounded back when estimating.

Note: Estimates assume a standard barbell deadlift from the floor. Trap-bar, block pulls, and stiff-leg variations use different leverages—track them separately. For coaching on form, see a qualified trainer.
Best rep range
About 3–8 reps
Heavier sets with fewer reps usually give tighter estimates than very high-rep deadlifts.
Popular picks
Epley & Brzycki
Switch formulas in settings to see how your estimated deadlift max shifts.
Typical zones
50%–100% of 1RM
Use the table for speed pulls, volume blocks, and heavy singles—match to your program.
Same tool, different lifts
Track separately
Sumo and conventional maxes differ—log the style you use for each estimate.
Heavy pulls
Stop before form breakdown
Estimated max is not permission to load blindly—use progressive overload and recovery.
Equipment
Standard deadlift pattern
Trap bar, RDL, and rack pulls are tracked separately from competition-style deadlift max.
If you deadlift 140 kg for 5 reps using the Epley formula, your estimated deadlift max is about 163.3 kg (rounded). Open the calculator to match your own numbers.
Input
140 kg × 5 reps
Estimated 1RM (Epley)
~163.3 kg
This tool estimates your deadlift one-rep max from a set you already completed—weight multiplied by repetitions. The same one-rep max relationships used in strength coaching (Epley, Brzycki, Lombardi) translate that performance into a predicted single-rep maximum, then into percentage loads for training.
Epley: 1RM = weight × (1 + reps / 30)Brzycki: 1RM = weight × (36 / (37 − reps))Lombardi: 1RM = weight × reps^0.10We convert to kilograms internally for the math, then show your deadlift max in your chosen display unit.
Use consistent technique when comparing estimates over time.
A deadlift max estimate helps you choose loads for volume, strength, and peaking phases without pulling a true max every week. Pair it with recovery planning using our TDEE calculator when you are dialing in nutrition around hard training blocks.
Pair with bench press max estimates for upper/lower balance and DOTS for meet-style comparisons.

Use 70–85% of this value for many volume weeks; reserve 90%+ for planned overload weeks.
