Deadlift Performance Calculator

Calculate your deadlift one-rep max (1RM) from any rep count. Get estimated 3RM, 5RM, and 10RM using the proven Epley formula.

Calculate your deadlift 1RM and rep maxes using the Epley formula.

About This Calculator

The Deadlift Performance Calculator estimates your deadlift one-rep max—the ultimate test of raw pulling strength. The deadlift engages more muscle mass than any other lift, from your grip down through your posterior chain to your legs. Using the Epley formula, predict your max safely.

The deadlift is often the lift where people can move the most weight. It's a true test of total-body strength and is highly transferable to real-world activities like lifting heavy objects. For most lifters, the deadlift represents their highest competition number.

The Epley Formula

1RM = Weight × (1 + Reps / 30)

For deadlifts, this formula tends to be accurate. High-rep deadlift sets (10+) are less common due to grip fatigue and form breakdown.

Practical Example

If you deadlift 315 lbs for 5 reps: 1RM = 315 × (1 + 5/30) = 315 × 1.167 = 368 lbs. Your 3RM would be approximately 342 lbs (93% of 368).

Tips for Deadlift Progress

  • Conventional vs sumo: choose based on your leverages and comfort
  • Deficit deadlifts strengthen the bottom portion; rack pulls build lockout
  • Grip training (farmers walks, dead hangs) prevents grip from being the weak link
  • Keep the bar close to your body throughout the lift for efficiency

Common Mistakes to Avoid

  • Rounding the lower back: Lumbar flexion under load is the #1 injury risk. Brace core, chest up, and maintain neutral spine throughout.
  • Bar drifting away from body: Keep the bar in contact with your legs (shins, then thighs). Bar drift forward increases lower back stress significantly.
  • Jerking the bar off the floor: Build tension gradually, then push the floor away. Jerking causes bicep tears and back injuries.
  • Ignoring grip training: Grip often fails before back and legs. Use chalk, train mixed grip sparingly, and add direct grip work (dead hangs, farmers walks).

Frequently Asked Questions

How is deadlift 1RM calculated?

Epley formula: 1RM = Weight × (1 + Reps/30). Example: 315 × 5 reps = 315 × 1.167 = 368 lb max. High-rep sets (10+) less accurate due to grip fatigue and form breakdown.

How much should I be able to deadlift?

Male standards: Beginner 1x bodyweight, Intermediate 1.5x, Advanced 2x, Elite 2.75x+. Deadlift is typically your strongest lift. 180lb advanced = 360+ lb deadlift.

Conventional vs sumo deadlift which is better?

Neither—depends on your body proportions. Long torso/short arms favor sumo. Short torso/long arms suit conventional. Try both and use what feels strongest and safest.
