Free powerlifting calculators

Estimate your 1RM from any set, find the weight for any reps at any RPE, score your total with DOTS and pick your meet attempts. Pounds or kilos, no sign-up, and every formula is shown on the page.

• 1RM calculator Estimated one-rep max from weight, reps and RPE, with a rep-max table.
• RPE calculator Load for reps at a target RPE, plus the RPE percentage chart.
• DOTS calculator DOTS score from total, bodyweight and sex, in lb or kg.
• Attempt calculator Opener, second and third attempts from a training max, rounded to 2.5 kg.

The calculators use the same math as the RawLift app: the estimated 1RM and RPE loads come from one function, and so does the DOTS score. A number you see here is the number you will see in your log.
