Squat Max Calculator
This calculator estimates your one rep max squat from a set you have already completed, then builds training percentages and a four-week plan around that number. Enter the weight lifted and the reps you managed to get started.
High-rep squat sets tend to underestimate a true 1RM more than other lifts, because breathing, bracing, and general conditioning become limiting well before your legs reach their true strength ceiling. For the most accurate estimate, use a set of 3 to 6 reps rather than a long grinding set.
How the estimate is calculated
The calculator averages three formulas, Epley, Brzycki, and Lombardi, to project your max from the weight and reps you enter. Averaging them reduces the bias any single formula carries and gives a steadier number to train from.
Squat standards are commonly expressed as a bodyweight multiple for adult men: roughly 0.75x bodyweight is untrained, 1x is novice, 1.25x is intermediate, 1.75x is advanced, and 2.25x is elite. A 200 lb man squatting 250 lb therefore sits at an intermediate level.
Frequently asked questions
What is a good squat for my bodyweight?
For adult men, squatting 1.25x bodyweight is a reasonable intermediate standard, 1.75x is advanced, and 2.25x is elite. These are population averages, so leg length and training age will move any individual off the line.
Do high-rep squat sets give accurate 1RM estimates?
Not as reliably as other lifts. Breathing, bracing, and conditioning fatigue limit a long squat set before your legs reach their true maximum, which makes the estimate read low. Use a set of 3 to 6 reps for a closer projection.
Should I count depth-questionable reps in my estimate?
No. Only count reps that reach at least parallel (femur level with the floor); powerlifting judges apply the stricter below-parallel standard, hip crease below the top of the knee. Shallow reps let you move more weight than a full-depth single, so including them inflates the estimate.
How often should I test my squat max?
You rarely need to test a true squat single at all, since this estimate updates every time you set a rep record. If you do test, once every 8 to 12 weeks is plenty, because a max attempt is fatiguing and offers little that a good estimate does not.
