Powerlifting calculators.
The maths behind PrimedLifter, free and open to anyone. Same formulas the app uses to build your programs — no signup, works in kg or lbs.
DOTS calculator
Score your total with DOTS, Wilks, and IPF GL Points. Work backwards from a target score to the total you need, and see which of the three lifts is lagging for your sex and bodyweight.
Open the calculator →RPE calculator
Turn weight, reps, and RPE into an estimated 1RM, then read off what to load for any other rep-and-RPE target. Includes a backdown calculator with all five schemes the program builder supports.
Open the calculator →Warmup calculator
Build a warmup ramp up to your opener across as many sets as you have time for, with even jumps or tapered so they tighten as the bar gets heavy — and the plates to load per side.
Open the calculator →Attempt planner
Pick openers and second and third attempts from your current maxes, at conservative, normal, or aggressive risk. Track made and missed lifts and see the total, DOTS, and IPF GL you walk away with.
Open the calculator →Strength standards
Where your lifts sit against everyone else once bodyweight, sex, and age are accounted for — squat, bench, and deadlift plus the movements no standards site covers, like the weighted dip and pull-up. Held back until the numbers behind every lift can be sourced honestly.
Coming soonThe calculators are the small part.
PrimedLifter builds whole training blocks in RPE or percentages, then recalculates every bar weight when your training max moves. Free for self-coached lifters.
