Weighted pull-up one rep max calculator
Estimate your one rep max on the weighted pull-up from a set you have already done. All five published equations are shown, because they agree at low repetitions and diverge above ten.

These are estimates from population-level equations, not a measurement of you and not medical advice. Individual results vary widely. Talk to a doctor or a registered dietitian before making significant changes to how you eat or train.
The weighted pull-up specifically
The weighted pull-up adds external load to a bodyweight movement, which changes how a maximum should be calculated.
A caution specific to this movement: the equations need total system load — bodyweight plus added weight — not the added weight alone. Feeding them only the added plate produces an answer that is wrong by the size of the lifter.
- Add your bodyweight to the added load before using any 1RM equation, then subtract it again from the result.
- Because bodyweight dominates the total, small changes in bodyweight move the estimate independently of strength.
- Grip width and whether the chin clears the bar both change the standard; keep them constant between tests.

Estimated weighted pull-up max by weight and reps
Epley estimates in kilograms. Read across from the weight you lifted and down from the repetitions you managed. Columns beyond ten repetitions are shown but are the least reliable.

Questions
- How do I estimate my weighted pull-up max?
- Take a set to or near failure, enter the weight and the repetitions, and the equations do the rest. A heavy triple gives a far more reliable estimate than a set of twelve, because all five equations were validated in the two to ten repetition range.
- Are 1RM estimates accurate for the weighted pull-up?
- The equations need total system load — bodyweight plus added weight — not the added weight alone. Feeding them only the added plate produces an answer that is wrong by the size of the lifter.
- Which formula should I use?
- Wathan and Epley track measured data across the widest range; Brzycki is the most conservative and is exact at a single repetition. The average of all five is a more defensible single number than any one of them, and the spread between them tells you how much confidence the estimate deserves.
- What repetition range suits the weighted pull-up?
- This lift is usually trained in the 3 to 8 repetition range. Estimates taken from within that range are the most trustworthy, because they sit closest to where the equations were fitted.
- Should I test a true maximum instead?
- Only if you need the number for competition, and then with a spotter and a full warm-up. For programming, an estimate from a heavy triple is nearly as useful and costs far less recovery and risk.
