Purpose and context
What does the Squat 1RM Calculator do?
The squat estimate uses general repetition equations, so consistent depth, bar position and technique are important when comparing sessions.
Who it supports: Adults performing consistent barbell squat technique.
Transparent calculation
Formula and calculation method
The shared 1RM engine calculates both equations from squat load and repetitions, then builds the training-percentage table from the selected estimate.
Worked calculation example
A 100 kg squat for 5 reps gives an Epley estimate of about 116.7 kg.
The live calculator retains greater internal precision and rounds only when presenting the result.
How to use the Squat 1RM Calculator
- Use a challenging set with consistent squat depth.
- Enter load and valid repetitions.
- Compare formulas before using the training table.
Understanding your result
The result card identifies the value, unit, method, supporting values and an accuracy notice. Estimated and predicted outputs are labelled so that apparent precision is not mistaken for certainty.

Accuracy, assumptions and limitations
Depth, equipment, bar position, fatigue and repetition speed can alter performance and equation accuracy.
Common input and interpretation mistakes
- Comparing different squat depths as equivalent.
- Including assisted or failed repetitions.
- Using a high-repetition conditioning set as a precise max test.

Frequently asked questions about Squat 1RM Calculator
Yes. The equation sees only load and reps, so depth must be consistent for meaningful comparison.
They are different exercises and should be tracked separately.
They model the load-repetition relationship differently, especially as reps increase.
Round to a load supported by available plates and appropriate for the training plan.
