How to Read the RPE Chart

Find your rep count on the left column and your RPE across the top. The intersection gives you the percentage of your 1RM that combination represents. For example, 5 reps at RPE 8 = 81.1% of your 1RM.

Enter your estimated 1RM above to convert all percentages to actual training weights for quick reference during your workouts.

RPE Scale Quick Reference

What each RPE value means in terms of effort and reps left

10
Max effort 0 RIR

Absolute failure. No reps left in the tank.

9.5
Near max 0-1 RIR

Maybe 1 more rep with ugly form.

9
Very hard 1 RIR

Definitely 1 more rep available.

8.5
Hard 1-2 RIR

Definitely 1, maybe 2 more reps.

8
Challenging 2 RIR

Could do 2 more reps. Good working intensity.

7.5
Moderate-hard 2-3 RIR

Could do 2-3 more reps.

7
Moderate 3 RIR

3 more reps. Speed work / technique focus.

6.5
Light-moderate 3-4 RIR

3-4 reps left. Warm-up territory.

6
Light 4+ RIR

4+ reps left. Easy warm-up effort.

Frequently Asked Questions

This RPE chart is based on Mike Tuchscherer's adaptation of Gunnar Borg's RPE scale for resistance training. The percentages represent the relationship between reps performed, perceived exertion, and the corresponding percentage of your one-rep maximum (1RM). It is the most widely used RPE chart in powerlifting and strength training.
Use the chart to determine training weights. If your program calls for 5 reps at RPE 8, find the intersection (81.1%) and multiply by your E1RM. For a 400 lb E1RM: 400 x 0.811 = 324 lb, rounded to 325 lb. This autoregulates your training to match your daily readiness.
Traditional programs use fixed percentages (e.g., 80% for 5 reps) regardless of how you feel. RPE-based training adjusts for daily readiness - if you are feeling great, RPE 8 might be heavier than 80%; if you are fatigued, it might be lighter. This leads to better long-term progress and reduced injury risk.
This is expected and reflects the reality that the same weight can feel different depending on fatigue. For example, 3 reps at RPE 10 (92.2%) is the same as 1 rep at RPE 8 (92.2%). This means a weight you can triple as an absolute max is also your "comfortable single" - both represent 92.2% of your 1RM.

RPE percentages are approximations based on population averages. Individual variation is normal. Use this chart as a starting point and adjust based on your personal experience.
