Squat 1rm Calculator

Whether you’re a beginner lifter or an experienced athlete, knowing your one-rep max (1RM) for squats is essential for designing effective strength training programs. The Squat 1RM Calculator is a handy online tool that allows you to estimate the maximum weight you can lift in a single squat repetition based on the weight you can lift for multiple reps.

This tool is perfect for tracking strength progress, planning workouts, and ensuring safe, efficient training. Unlike trial-and-error lifting, the calculator gives a precise estimation, saving you time and reducing the risk of injury.

How the Squat 1RM Calculator Works

The calculator uses the Epley formula, a widely recognized method for estimating one-rep max: 1RM=Weight×(1+Reps30)\text{1RM} = \text{Weight} \times \left(1 + \frac{\text{Reps}}{30}\right)1RM=Weight×(1+30Reps​)

Here, “Weight” is the amount you can lift for a certain number of repetitions, and “Reps” is the number of repetitions you can complete at that weight. By inputting these values, the tool instantly calculates your estimated 1RM.

Step-by-Step Instructions to Use the Tool

Using the Squat 1RM Calculator is straightforward and beginner-friendly:

1. Enter the Weight Lifted:
   • Input the amount of weight (in pounds) you can currently lift for your target number of repetitions.
   • Example: 200 lbs.
2. Enter the Number of Repetitions:
   • Input how many reps you completed with that weight.
   • Example: 5 reps.
3. Click “Calculate 1RM”:
   • The tool will show a progress bar while processing.
   • Within seconds, your estimated one-rep max will appear.
4. View Results:
   • The 1RM will be displayed clearly in the results section.
   • You can copy your results or share them with friends or on social media using the provided buttons.
5. Reset if Needed:
   • Click “Reset” to clear your entries and calculate again with different inputs.

Practical Example

Suppose you can squat 200 lbs for 5 reps.

Using the Epley formula: 1RM=200×(1+530)=200×1.1667≈233.3 lbs\text{1RM} = 200 \times \left(1 + \frac{5}{30}\right) = 200 \times 1.1667 \approx 233.3 \text{ lbs}1RM=200×(1+305​)=200×1.1667≈233.3 lbs

Your estimated one-rep max is 233 lbs. This number can guide your training weights for strength programs, hypertrophy, or endurance workouts.
