RepolveGet the appDeadlift one-rep max calculator.
Estimate your deadlift one-rep max from a completed set and see its exercise score against Repolve’s deadlift standards.
Calculate your deadlift score
Enter the total barbell weight, including the bar. Use a completed set of 1–12 reps. Inputs stay in your browser.
A worked deadlift example
A 120 kg deadlift for 5 reps produces a 140 kg estimated max, or 1.75× an 80 kg bodyweight. Use the total bar and plates, and keep the start height and rep style consistent when comparing another session.

Illustrative example using 80 kg bodyweight and male standards. Choosing female standards changes the exercise score, not the estimated max. This is one exercise score, not an overall Strength Score.
Deadlift rep-to-max examples
Each row uses a completed set at 120 kg. Enter the total barbell weight, including the bar. These are formula examples, not suggested loads to attempt.
| Completed reps | Estimated 1RM |
|---|---|
| 1 | 120.0 kg |
| 3 | 132.0 kg |
| 5 | 140.0 kg |
| 8 | 152.0 kg |
| 10 | 160.0 kg |
| 12 | 168.0 kg |
A one-rep set uses the entered load. Sets of 2–12 reps use weight × (1 + reps ÷ 30). The result estimates a single repetition; it is not a guarantee that you can lift that weight.
Muscles worked
Back, glutes, and hamstrings, with grip and trunk involvement. In Repolve’s scoring model, this exercise supplies primary evidence for back. Training involvement and scoring coverage are different things.
Make your sessions comparable
Keep the starting height, stance, and use of straps consistent. Reps reset on the floor and touch-and-go reps may not be equivalent. Note these differences when deciding whether two sessions are comparable.
How the estimate works
For a single rep, the estimate is the load entered. For 2–12 reps, the production engine uses the Epley estimate: weight × (1 + reps ÷ 30). It compares the resulting estimated max with bodyweight and the exercise’s sex-specific thresholds. This is an estimate from a completed set, not a prescription for your next attempt.
Deadlift strength standards
These ratios come directly from Repolve’s production standards. They describe exercise benchmarks, not population percentiles or age-adjusted rankings.
| Reference | Score | Male | Female |
|---|---|---|---|
| Beginner | 20 | 1× | 0.5× |
| Novice | 40 | 1.5× | 1× |
| Intermediate | 60 | 2× | 1.25× |
| Advanced | 100 | 2.5× | 1.75× |
| Elite | 125 | 3× | 2.5× |
Enter the total barbell weight, including the bar. The same unit must be used for the lift and bodyweight. Understand the standards
Track progression
Track the set as well as the estimate. In Repolve’s current scoring model, deadlifts provide primary evidence for back. This does not mean your hamstrings or glutes were not involved; it means one lift is not used to invent a full lower-body profile.
Common variations
Romanian deadlifts are a separate exercise with separate standards. Rack pulls and other shortened-range variations should not be entered as full deadlifts to obtain a comparable score.
Deadlift calculator questions
Can I enter a Romanian deadlift or rack pull?
Use the exercise-specific entry in the full calculator for supported variations. A Romanian deadlift has its own standards; a shortened-range rack pull is not interchangeable with a full deadlift.
Why does a deadlift contribute to back in Repolve?
Back is the primary scoring group assigned to this exercise in the current model. That is an evidence-allocation convention, not a claim that deadlifts only train the back.

About this calculator
Written by Repolve to explain its own scoring model. Calculations and benchmark tables use the same engine and exercise standards as the app. Worked examples are illustrative, not customer results. Estimates describe logged performance; they do not directly measure muscle size or diagnose a training imbalance.
