RPE Calculator

An RPE calculator is a tool that helps you determine various aspects of your workout based on your RPE (Rate of Perceived Exertion). There are two main functionalities.

  • Estimating 1RM (one-rep max): You input the weight you lifted for a certain number of reps and your RPE for that set. The calculator then estimates your one-rep max weight based on that information. This helps you gauge your overall strength and plan future workouts with appropriate weight selections.

  • Calculating target weights: You input your desired RPE for a specific set or exercise. The calculator then provides you with the estimated weight you should lift to achieve that RPE level. This is useful for designing workouts that target specific intensity zones.

Monitor both your exercise intensity and blood glucose levels for comprehensive health management. Use our  RPE Calculator to gauge exercise intensity and our HbA1c Calculator to track long-term blood sugar control.


Q: What is RPE?

RPE stands for Rate of Perceived Exertion. It’s a way to measure your workout intensity based on how hard you feel you’re working, on a scale from 1 (very easy) to 10 (maximally exerted).

Q: What does the RPE calculator do?

This calculator uses your RPE to help you with two main things:

  • Estimate your 1RM (one-rep max): Tell it the weight you lifted for a certain number of reps and your RPE for that set. It will estimate your one-rep max based on that information.
  • Find the right weight for your workout: Input your desired RPE for a specific exercise, and the calculator will recommend a weight to lift to achieve that intensity level.

Q: Is the RPE calculator accurate?

The calculator provides estimates based on your input. For best results, be honest about your RPE and use the tool consistently over time to learn how RPE feels for you at different intensities.

Q: Who can benefit from the RPE calculator?

This calculator is helpful for both beginners and experienced lifters. Beginners can learn how to gauge their effort and avoid overexertion. Experienced lifters can use it to design workouts with specific intensity goals.

Q: Are there any limitations to the RPE calculator?

The calculator is a guide. It’s important to listen to your body and adjust weights or intensity as needed during your workout. Factors like sleep, nutrition, and fatigue can also affect your RPE.
