How do you calculate deadlift max from reps?

Enter the weight you pulled from the floor and reps completed (1–10). The calculator applies a 1RM formula. Epley (default): 1RM = weight × (1 + reps/30). Example — 140 kg × 5 reps: 140 × (1 + 5/30) = 163.33 kg estimated max. Brzycki: 140 × 36/(37−5) = 157.5 kg. Lombardi: 140 × 5^0.10 ≈ 164.45 kg. Pick one formula and stay consistent; all three are shown so you can compare programming loads.

What is a good deadlift max?

“Good” depends on body weight, sex, stance (conventional vs sumo), and training age. A rough male conventional guide: beginner ~0.75× bodyweight 1RM, novice ~1.0×, intermediate ~1.25×, advanced ~1.5×, elite ~2.0×+. An 80 kg lifter at intermediate might deadlift ~100 kg max; 225 lb × 5 (Epley) estimates ~262.5 lb 1RM — solid intermediate territory. Women and teens use lower multiples; powerlifters compare DOTS/Wilks on total (squat + bench + deadlift), not deadlift alone.

Which formula is best for deadlift — Epley or Brzycki?

For 3–8 rep sets near failure, Epley and Brzycki usually land within ~5% of each other. Our default (140 kg × 5): Epley 163.33 kg, Brzycki 157.5 kg, Lombardi 164.45 kg. Brzycki can read lower at higher reps; Lombardi sometimes reads highest. Many coaches use Epley in apps; Brzycki is common in powerlifting spreadsheets. Use the same formula when tracking block-to-block progress.

How accurate is an estimated deadlift 1RM?

Typical error is ±5–10% vs a true max test when the set is 3–6 reps with good form, full lockout, and near-max effort. Errors grow above 8 reps or if grip fails before back/legs. 100 kg × 8 (Brzycki) → ~124.14 kg estimated vs 180 kg × 3 (Epley) → ~198 kg — the heavy triple is usually a tighter guess. Treat output as programming weight, not a competition attempt without a full warm-up and belt setup.

What percentage of deadlift max should I train at?

Common zones from this calculator’s table: 50–60% for technique and speed pulls, 70% (~114.33 kg in the default example) for hypertrophy volume, 80–85% for heavy sets of 3–6, 90–95% for strength peaking. Default 140 kg × 5 → 1RM ~163.33 kg: 70% = 114.33 kg, 85% = 138.83 kg. Adjust by RPE (reps in reserve) — percentages are starting points, not mandates.

How many reps should I use to estimate deadlift max?

Best: 2–6 reps on a heavy top set with 0–2 reps in reserve. Acceptable: 7–10 (supported here but less accurate). Do not use 12+ rep sets — grip endurance and lower-back fatigue skew formulas. 180 kg × 3 reps → ~198 kg (Epley), often closer to a true max than a 10-rep set at the same RPE.

Does conventional vs sumo change my deadlift max estimate?

Yes. Most lifters have different maxes in conventional and sumo because hip and back demands differ. Log the stance you tested; comparing a sumo triple to a conventional program will misload the bar. Trap bar and rack pulls are separate lifts — do not mix them into one “deadlift max” number.

Is it safe to test a true one-rep deadlift max?

Max singles carry higher lower-back and biceps risk than submaximal work. Requirements: full warm-up, collars, mixed grip or hook grip decision, belt if you use one in training, and experience with heavy singles from the floor. Many lifters never test true 1RM and only use calculators from 3–5 rep PRs — that is valid for year-round training.

Can I use this for Romanian deadlift or rack pulls?

No — this page is for barbell pulls from the floor (competition-style deadlift). RDLs, rack pulls, and block pulls use different ranges of motion and loads. Track each variation separately. For bench or squat estimates, use our bench press max or squat max calculators.

How often should I update my deadlift max estimate?

After a block when you hit a new rep PR (e.g. 140 kg × 6 instead of × 5), or every 4–8 weeks. Do not recalculate from every warm-up set — daily readiness swings 2–5%. If estimates jump 10%+ in one week, verify bar weight (20 kg/45 lb bar included?) and rep count. A jump from 140×5 to ~163 kg 1RM to 150×5 would re-estimate higher — that is expected.

How do I convert deadlift max between kg and lb?

The calculator converts internally (1 kg = 2.205 lb). Example: 163.33 kg estimated max ≈ 360.1 lb. 405 lb × 3 (Brzycki) → ~428.82 lb 1RM. Enter lifts in the unit you train in; switch display unit in settings to see the table in lb or kg.
