What is RPE?
RPE (Rate of Perceived Exertion) is a subjective scale from 1-10 that measures how difficult a set feels. RPE 10 means maximum effort with no reps left in reserve, while RPE 9 means you could have done one more rep.

How to use
How to Use the RPE Load Calculator
- 01Enter the weight you lifted, the number of reps performed, and your RPE for that set in the "Have" section
- 02Your estimated one-rep max (E1RM) will be calculated automatically based on the Tuchscherer RPE model
- 03Enter your target reps and desired RPE in the "Want" section to calculate your recommended training weight
- 04Use the results to plan your training sessions with appropriate load management
RPE stands for Rate of Perceived Exertion - a subjective scale from 1-10 measuring how difficult a set feels. RPE 10 means maximum effort (no reps left in reserve), while RPE 9 means you had one rep left in the tank.

RPE Chart Reference
Use this chart to understand how RPE correlates with reps in reserve (RIR) and to help gauge your RPE during training.
| RPE | Description | Reps Left in Reserve |
|---|---|---|
| 10 | Maximum Effort | 0 |
| 9.5 | Nearly Maximal Effort | 0-1 |
| 9 | Very Hard Effort | 1 |
| 8.5 | Hard Effort | 1-2 |
| 8 | Challenging Effort | 2 |
| 7.5 | Moderate-Hard Effort | 2-3 |
| 7 | Moderate Effort | 3 |
| 6.5 | Somewhat Challenging | 3-4 |
| 6 | Somewhat Easy | 4 |
Advantages of RPE-Based Training
Auto-Regulation
RPE allows you to adjust training loads based on how you feel on a given day, accounting for recovery, stress, and readiness.
Progress Tracking
By monitoring how a specific weight feels over time, you can track progress even without increasing loads.
Injury Prevention
Using RPE helps prevent overtraining by ensuring you're not pushing beyond your recovery capabilities.
Personalization
Unlike fixed percentage-based programs, RPE adapts to your individual response to training stimuli.
Practical Applications
Main Lifts
For compound movements like squats, bench press, and deadlifts, working in the RPE 7-9 range is typically ideal for strength development.
Accessory Work
For assistance exercises, a moderate RPE of 6-8 is often sufficient to drive adaptation while managing fatigue.
Backoff Sets
After your main working sets, calculate backoff sets at RPE 7-8 with higher reps to accumulate volume without excessive fatigue.
Deload Periods
During deloads, target RPE 5-7 to maintain technique and provide recovery while still training with meaningful weights.
Training Recommendations
01
Using RPE Effectively
For most strength development, work in the RPE 7-9 range. RPE 10 should be used sparingly as it carries higher fatigue cost. For beginners, focus on learning proper RPE assessment before relying heavily on it for load selection.
02
Weekly Programming
Consider varying RPE throughout the week: higher RPE (8-9) for main strength days, and lower RPE (6-8) for volume or technique days. This helps manage fatigue while still providing sufficient stimulus.

Frequently Asked Questions
How accurate is E1RM calculation?
E1RM (Estimated 1 Rep Max) calculations are approximations based on the Tuchscherer RPE chart. Accuracy tends to decrease with higher rep ranges (10+ reps). For best results, use sets of 1-5 reps at RPE 8 or higher.
How should I use this calculator?
This calculator serves two main purposes: 1) Estimating your 1RM based on submaximal lifts, and 2) Calculating appropriate loads for planned sets based on your current strength level. It's particularly useful for autoregulating training intensity.
What is the difference between percentage-based and RPE-based training?
Percentage-based training prescribes weights as a percentage of your 1RM. RPE-based training adjusts weights based on your daily readiness and performance. RPE allows for autoregulation on days when you're feeling stronger or weaker than usual.
