About

RPE Chart turns reps and RPE into a share of your one-rep max. It estimates your 1RM from a set you did, and it shows the weight to lift for any other reps and RPE, rounded to your plates. It works in pounds and kilograms, and in RPE or RIR.

What it does

It answers as you type. Every number in the chart is editable, so you can match the chart your coach uses. The calculator reads your edited values.

How it works

The percentages come from the RPE chart of Mike Tuchscherer of Reactive Training Systems (RTS). The page has two versions, and you pick one: the current RTS table (the default) and the chart from the 2016 RTS article "Customizing Your RPE Chart". They differ by up to 7.6 points at high reps. The Sources section on the home page names where each table was read from. The RPE scale based on reps in reserve comes from Zourdos and colleagues (2016) and Helms and colleagues (2016). The tool divides your weight by the chart percentage to estimate your 1RM. It then multiplies your 1RM by another percentage to get a target weight, and rounds to the plate jump you choose.

The calculator runs in your browser and does not send what you type. We do not ask you to create an account. Your settings and chart edits stay on your device.

A note on safety

The numbers are estimates. This tool is not medical advice and does not replace a coach. If you have a health condition or an injury, ask a doctor before you train hard. Use collars, check your equipment and ask for a spotter on heavy sets.
