Input your estimated one-rep max (1RM), and let our calculator do the heavy lifting, providing you with a clear, actionable plan for progressive overload across your main lifts.

Calculate Your 5/3/1 Program

Estimated 1 Rep Max (1RM) (kg/lbs):

Enter your best estimated 1 Rep Max for a specific lift (e.g., Squat, Bench Press).

Training Max (TM) Percentage (%):

Typically 90% of your 1RM. Adjust if you prefer a more conservative or aggressive approach.

Weight Rounding Increment (kg/lbs):

Weights will be rounded to the nearest increment (e.g., 2.5 for standard plates).

Your 5/3/1 Cycle Results

Training Max (TM): 0 kg/lbs

Estimated 1RM: 0 kg/lbs

Training Max Percentage: 0%

Rounding Increment: 0 kg/lbs

The Training Max (TM) is calculated as your Estimated 1RM multiplied by the Training Max Percentage. All working sets are then derived as percentages of this Training Max, rounded to your specified increment.

What is a 5/3/1 calculator?

A 5/3/1 calculator is an essential tool for anyone following Jim Wendler’s popular 5/3/1 strength training program. This program is renowned for its simplicity, effectiveness, and focus on consistent, long-term progress. The core principle of 5/3/1 revolves around using a “Training Max” (TM), which is typically 90% of your estimated one-rep max (1RM), rather than your true 1RM. This conservative approach helps prevent overtraining, allows for consistent gains, and reduces the risk of injury.

The 5/3/1 calculator automates the complex percentage-based calculations required for each week of the program. Instead of manually figuring out 65% of your TM, then 75%, and so on, the calculator provides all the precise weights you need for your main lifts (Squat, Bench Press, Deadlift, Overhead Press) across a four-week cycle. It ensures accuracy, saves time, and allows you to focus purely on your training.

Who should use a 5/3/1 calculator?

Beginners and Intermediates: Those new to structured strength training or looking to move beyond novice programs will find the 5/3/1 program and its calculator invaluable for building a strong foundation.
Experienced Lifters: Even advanced athletes use the 5/3/1 program for continued strength gains, especially when recovering from plateaus or injuries, or when focusing on long-term, sustainable progress.
Powerlifters and Bodybuilders: The program’s emphasis on the main compound lifts makes it ideal for powerlifters, while its progressive overload principles support muscle growth for bodybuilders.
Anyone seeking structured progression: If you’re tired of guessing your weights or hitting plateaus, a 5/3/1 calculator provides a clear, scientific path forward.

Common misconceptions about the 5/3/1 program

It’s only for advanced lifters: While popular among experienced athletes, 5/3/1 is highly adaptable and beneficial for lifters of all levels.
You must hit PRs every week: The program emphasizes slow, consistent progress. The “plus” sets are for pushing, but not necessarily for new 1RM attempts.
Assistance work isn’t important: Wendler provides various templates for assistance work (e.g., Boring But Big, FSL, BBB Challenge) which are crucial for overall development.
The Training Max is your actual 1RM: This is a critical distinction. The TM is a sub-maximal weight (usually 90% of 1RM) to ensure sustainable progress and reduce burnout.

5/3/1 calculator Formula and Mathematical Explanation

The core of the 5/3/1 program, and thus the 5/3/1 calculator, lies in its simple yet effective percentage-based calculations. It all starts with your Training Max (TM).

Step-by-step derivation:

Determine your Estimated 1 Rep Max (1RM): This is the maximum weight you can lift for one repetition. If you don’t know your true 1RM, you can estimate it using a one-rep max calculator based on a set of reps (e.g., 5 reps at a certain weight).
Calculate your Training Max (TM): The TM is the foundation of the entire program. It’s typically 90% of your estimated 1RM.

Training Max (TM) = Estimated 1RM × Training Max Percentage (e.g., 0.90)
Calculate Weekly Working Sets: Each week of the 5/3/1 cycle uses specific percentages of your TM for the main working sets. These percentages are fixed:
- Week 1 (5s Week): 65% x 5 reps, 75% x 5 reps, 85% x 5+ reps
- Week 2 (3s Week): 70% x 3 reps, 80% x 3 reps, 90% x 3+ reps
- Week 3 (1s Week): 75% x 5 reps, 85% x 3 reps, 95% x 1+ reps
- Week 4 (Deload Week): 40% x 5 reps, 50% x 5 reps, 60% x 5 reps
The “+” sign indicates “as many reps as possible” (AMRAP) on the final set, aiming to beat previous rep records.
Round Weights: To ensure practicality in the gym, all calculated weights are rounded to the nearest plate increment (e.g., 2.5 kg or 5 lbs). This is where the 5/3/1 calculator truly shines, as manual rounding can be tedious.

Practical Examples (Real-World Use Cases)

Let’s walk through a couple of examples to see how the 5/3/1 calculator works in practice.

Example 1: Bench Press Progression

John wants to improve his Bench Press. He recently hit 120 kg for a single rep, so his estimated 1RM is 120 kg. He’ll use the standard 90% Training Max and round to the nearest 2.5 kg.

Input: Estimated 1RM = 120 kg, Training Max Percentage = 90%, Rounding Increment = 2.5 kg
Calculation:
- Training Max (TM) = 120 kg * 0.90 = 108 kg
- Week 1 (5s Week):
  - Set 1: 108 kg * 0.65 = 70.2 kg → 70 kg x 5
  - Set 2: 108 kg * 0.75 = 81 kg → 80 kg x 5
  - Set 3: 108 kg * 0.85 = 91.8 kg → 92.5 kg x 5+
- Week 2 (3s Week):
  - Set 1: 108 kg * 0.70 = 75.6 kg → 75 kg x 3
  - Set 2: 108 kg * 0.80 = 86.4 kg → 87.5 kg x 3
  - Set 3: 108 kg * 0.90 = 97.2 kg → 97.5 kg x 3+
- Week 3 (1s Week):
  - Set 1: 108 kg * 0.75 = 81 kg → 80 kg x 5
  - Set 2: 108 kg * 0.85 = 91.8 kg → 92.5 kg x 3
  - Set 3: 108 kg * 0.95 = 102.6 kg → 102.5 kg x 1+
- Week 4 (Deload Week):
  - Set 1: 108 kg * 0.40 = 43.2 kg → 42.5 kg x 5
  - Set 2: 108 kg * 0.50 = 54 kg → 55 kg x 5
  - Set 3: 108 kg * 0.60 = 64.8 kg → 65 kg x 5
Interpretation: John now has a precise plan for his next 4 weeks of Bench Press training. He knows exactly what weights to load, ensuring he’s working effectively without overshooting his capacity. After this cycle, he’ll typically add 2.5 kg to his 1RM for the next cycle and recalculate using the 5/3/1 calculator.

Example 2: Deadlift Progression with a Conservative TM

Sarah is training for a powerlifting meet and wants to be conservative with her Deadlift to avoid burnout. Her estimated 1RM is 400 lbs. She decides to use an 85% Training Max and rounds to the nearest 5 lbs.

Input: Estimated 1RM = 400 lbs, Training Max Percentage = 85%, Rounding Increment = 5 lbs
Calculation:
- Training Max (TM) = 400 lbs * 0.85 = 340 lbs
- Week 1 (5s Week):
  - Set 1: 340 lbs * 0.65 = 221 lbs → 220 lbs x 5
  - Set 2: 340 lbs * 0.75 = 255 lbs → 255 lbs x 5
  - Set 3: 340 lbs * 0.85 = 289 lbs → 290 lbs x 5+
- Week 2 (3s Week):
  - Set 1: 340 lbs * 0.70 = 238 lbs → 240 lbs x 3
  - Set 2: 340 lbs * 0.80 = 272 lbs → 270 lbs x 3
  - Set 3: 340 lbs * 0.90 = 306 lbs → 305 lbs x 3+
- Week 3 (1s Week):
  - Set 1: 340 lbs * 0.75 = 255 lbs → 255 lbs x 5
  - Set 2: 340 lbs * 0.85 = 289 lbs → 290 lbs x 3
  - Set 3: 340 lbs * 0.95 = 323 lbs → 325 lbs x 1+
- Week 4 (Deload Week):
  - Set 1: 340 lbs * 0.40 = 136 lbs → 135 lbs x 5
  - Set 2: 340 lbs * 0.50 = 170 lbs → 170 lbs x 5
  - Set 3: 340 lbs * 0.60 = 204 lbs → 205 lbs x 5
Interpretation: By using an 85% TM, Sarah ensures her working weights are slightly lighter, allowing for better recovery and technique focus, which is crucial leading up to a competition. The 5/3/1 calculator provides her with the exact weights, removing any guesswork.

How to Use This 5/3/1 calculator

Our 5/3/1 calculator is designed for ease of use, providing you with accurate results in just a few simple steps.

Step-by-step instructions:

Enter your Estimated 1 Rep Max (1RM): In the first input field, enter your best estimated 1RM for the specific lift you’re planning (e.g., Squat, Bench, Deadlift, OHP). This should be a weight you can lift for one maximal repetition. If you don’t know it, use a one-rep max calculator to estimate it from a heavier set of reps.
Set your Training Max (TM) Percentage: The default is 90%, which is standard for the 5/3/1 program. You can adjust this percentage (e.g., 85% for a more conservative approach, or 95% for a more aggressive one, though 90% is highly recommended by Wendler).
Specify Weight Rounding Increment: Enter the smallest weight plate increment available in your gym (e.g., 2.5 for kilograms, 5 for pounds). This ensures your calculated weights are practical and loadable.
View Your Results: As you enter or change values, the 5/3/1 calculator will automatically update the results.

How to read the results:

Intermediate Results: These confirm your input values (Estimated 1RM, TM Percentage, Rounding Increment) for quick reference.
Detailed Weekly Working Sets Table: This table provides a comprehensive breakdown of the exact weights and reps for each of your three main working sets across the four-week cycle (Week 1: 5s, Week 2: 3s, Week 3: 1s, Week 4: Deload).
Heaviest Working Set Progression Chart: A visual representation of the heaviest set for each week, allowing you to see the progression and deload clearly.

Decision-making guidance:

Consistency is Key: The 5/3/1 program thrives on consistent, incremental progress. Stick to the calculated weights.
“As Many Reps As Possible” (AMRAP): On the final set of Weeks 1, 2, and 3, push for as many quality reps as possible beyond the prescribed minimum. This is where you build strength and gauge progress.
Deload Week: Do not skip the deload week (Week 4). It’s crucial for recovery, preventing burnout, and ensuring long-term gains.
Progression: After completing a 4-week cycle, typically add 2.5 kg (5 lbs) to your upper body lifts’ 1RM and 5 kg (10 lbs) to your lower body lifts’ 1RM, then re-enter these new 1RMs into the 5/3/1 calculator for your next cycle.
Assistance Work: Remember that the 5/3/1 program includes assistance work. While this calculator focuses on the main lifts, ensure you incorporate appropriate accessory exercises as outlined by Jim Wendler (e.g., Boring But Big, First Set Last, Joker Sets).

Key Factors That Affect 5/3/1 calculator Results

While the 5/3/1 calculator provides precise numbers, several factors influence the effectiveness and outcome of your 5/3/1 program.

Accuracy of Estimated 1RM: The entire program is built upon your 1RM. An overestimated 1RM will lead to weights that are too heavy, causing missed reps, stalled progress, and potential injury. An underestimated 1RM might mean you’re not challenging yourself enough. Use a reliable one-rep max calculator or perform a conservative 1RM test.
Training Max (TM) Percentage: The standard 90% TM is recommended for a reason – it allows for consistent progress without burning out. A higher TM (e.g., 95%) can lead to faster initial gains but also quicker plateaus. A lower TM (e.g., 85%) offers more recovery and can be beneficial during cutting phases or for very advanced lifters.
Consistency and Adherence: The 5/3/1 program is a long-term strategy. Skipping workouts, not following the prescribed percentages, or failing to perform the “plus” sets will undermine the program’s effectiveness.
Nutrition and Recovery: Adequate sleep, proper nutrition (including sufficient protein and calories, which you can track with a macro calculator or calorie calculator), and stress management are paramount. Without these, your body cannot recover and adapt to the training stimulus, regardless of how perfectly your weights are calculated by the 5/3/1 calculator.
Assistance Work Selection: While the 5/3/1 calculator focuses on the main lifts, the assistance work is crucial for addressing weaknesses, building muscle mass, and improving overall work capacity. Choosing appropriate assistance templates (e.g., Boring But Big, First Set Last) is vital.
Progressive Overload Strategy: After each cycle, you’re expected to increase your 1RM (and thus your TM) slightly. Typically, 2.5 kg (5 lbs) for upper body lifts and 5 kg (10 lbs) for lower body lifts. Failing to consistently apply this progressive overload will halt your strength gains.
Deload Protocol: The deload week is not optional. It’s built into the program to manage fatigue and allow for supercompensation. Skipping it can lead to overtraining and injury.
Form and Technique: Lifting with poor form not only increases injury risk but also reduces the effectiveness of the exercise. Focus on perfect technique, even if it means using slightly lighter weights than the 5/3/1 calculator suggests initially.

Frequently Asked Questions (FAQ)

Q: How often should I use the 5/3/1 calculator?

A: You should use the 5/3/1 calculator at the beginning of each new 4-week cycle. After completing a cycle, you’ll typically increase your estimated 1RM for each lift (e.g., 2.5 kg for upper body, 5 kg for lower body) and then recalculate your new Training Max and working weights.

Q: What if I miss reps on a “plus” set?

A: Missing reps on a “plus” set is a sign that your Training Max might be too high, or your recovery is insufficient. It’s often recommended to lower your Training Max by 10% for the next cycle if you consistently miss reps, then build back up. The 5/3/1 calculator can help you adjust quickly.

Q: Can I use different Training Max percentages for different lifts?

A: Yes, you can. Some lifters prefer a more conservative TM (e.g., 85%) for lifts like the Deadlift due to its high recovery demands, while using 90% for others. Our 5/3/1 calculator allows you to input a specific percentage for each calculation.

Q: What’s the difference between 1RM and Training Max?

A: Your 1RM (One Rep Max) is the absolute maximum weight you can lift for one repetition. Your Training Max (TM) is a sub-maximal percentage of your 1RM (usually 90%) used for programming. The TM is a strategic tool to ensure sustainable progress and prevent burnout, making the 5/3/1 calculator crucial for managing this distinction.

Q: How do I choose the right rounding increment?

A: Choose the smallest plate increment available in your gym. If your gym has 1.25 kg plates, use 1.25. If only 2.5 kg plates, use 2.5. For pounds, typically 2.5 lbs or 5 lbs. This ensures the weights calculated by the 5/3/1 calculator are practical.

Q: Is the 5/3/1 program suitable for cutting or bulking?

A: Yes, 5/3/1 is highly adaptable. During a cut, you might opt for a lower Training Max percentage (e.g., 85%) and focus on maintaining strength. During a bulk, you can stick to the standard 90% TM and focus on pushing the “plus” sets. The 5/3/1 calculator helps you adjust your weights accordingly.

Q: What if my 1RM hasn’t increased after a cycle?

A: If your 1RM hasn’t increased, it’s a sign to re-evaluate. This could be due to insufficient recovery, poor nutrition, an overestimated initial 1RM, or inadequate assistance work. Consider a “reset” by lowering your Training Max by 10% and building back up, or re-evaluating your estimated 1RM with a strength training calculator.

Q: Can I use this 5/3/1 calculator for all my lifts?

A: Absolutely! You should use the 5/3/1 calculator for each of your main lifts (Squat, Bench Press, Deadlift, Overhead Press) independently, as each lift will have its own 1RM and progression. Simply input the specific 1RM for each lift to get its unique cycle plan.
