GymNoteDeadlift calculator (1RM)
Enter the weight and reps from your last deadlift set to see your max and what to lift at 60–95%.
1 to 12. Fewer reps give a closer estimate.
How to estimate your deadlift max
Deadlift technique breaks down faster than on other lifts, especially late in a long set. So use a shorter set of 2–5 reps rather than the usual 3–5.
- Start every rep from a dead stop without bouncing the plates off the floor.
- End the set when your back starts to round. Only count the reps before that point.
- Always test with the same grip and the same style, conventional or sumo.
What to do with your result
Deadlifts are tiring, so keep heavy sets above 85% of your max less frequent than on the squat. For most sessions 70–80% is plenty.
| % of max | Weight | Reps to failure |
|---|---|---|
| 100% | 154 kg | 1 |
| 95% | 146.3 kg | ~2 |
| 90% | 138.6 kg | ~3 |
| 85% | 130.9 kg | ~5 |
| 80% | 123.2 kg | ~8 |
| 75% | 115.5 kg | ~10 |
| 70% | 107.8 kg | ~13 |
| 65% | 100.1 kg | ~16 |
| 60% | 92.4 kg | ~20 |
How do I calculate my deadlift max?
Do a set of 2–5 reps with a neutral back and enter the weight and reps. For example, 140 kg × 3 reps gives an estimated max of about 154 kg.
Do straps or a mixed grip change the result?
They can, because your grip stops being the limit. Note what you used and test the same way each time.
Does it work for Romanian or stiff-leg deadlifts?
It gives a max for that variation, but the number will not transfer to a conventional deadlift.
