A powerlifting RPE load chart is an essential tool that helps athletes balance intensity and recovery by linking the Rate of Perceived Exertion (RPE), repetitions, and percentage of one-rep max (1RM). It provides a clear visual guide showing how much weight to lift based on effort levels—allowing lifters to train smart rather than simply heavy. By referencing a powerlifting load chart, athletes can estimate their 1RM, plan progressive overload, and adjust daily loads according to performance and fatigue, ensuring consistent strength gains and reduced injury risk.

How to Read the Chart
- Find your number of reps in the first column.
- Move across to your target RPE column.
- The percentage value shows roughly what portion of your 1 Rep Max (1RM) you are lifting.
Example:
If you’re doing 5 reps at RPE 8, you’re lifting about 78% of your 1RM.
If your 1RM is 150 kg, your working weight ≈ 150 × 0.78 = 117 kg
How to Use Powerlifting RPE Load Chart with the Calculator
- Enter your actual set (weight, reps, and RPE) into the “Have” side of the calculator to find your E1RM.
- Then, use the “Want” side or this chart to predict weights for future sets at different RPE levels.
FAQs
| 1. How to Calculate RPE? Use this simple formula: RPE = 10 − Reps in Reserve (RIR) Reps in Reserve (RIR) means how many reps you could still perform before reaching failure. Example: You lifted 100 kg for 5 reps, and you felt you could have done 1 more rep. → RIR = 1 → RPE = 10 − 1 = 9 RPE 9 means you had one rep left before failure. 2. How to Calculate 1RM? 1RM (One-Rep Max) is the maximum weight you can lift for one repetition. It can be estimated using a submaximal set (weight, reps, and RPE) with this formula: Estimated 1RM = Weight ÷ (% of 1RM for that reps and RPE) You get the percentage from an RPE load chart. Example: You lifted 100 kg × 5 reps @ RPE 8. From the chart, 5 reps @ RPE 8 ≈ 78% of 1RM. So, 1RM = 100 ÷ 0.78 = 128 kg (approx.) Your estimated 1RM = 128 kg. |
