How to Use the RPE Load Calculator

Enter the weight you lifted, the number of reps performed, and your RPE for that set in the "Have" section
Your estimated one-rep max (E1RM) will be calculated automatically based on the Tuchscherer RPE model
Enter your target reps and desired RPE in the "Want" section to calculate your recommended training weight
Use 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.

RPE Calculation Methodology

Our calculator uses Mike Tuchscherer's RPE chart, which has been widely adopted in the powerlifting community. The formula converts your weight, reps, and RPE into an E1RM, then calculates target weights based on that estimation.

Frequently Asked Questions

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 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.

Training Recommendations

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.

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.
