RPE Calculator: Powerlifting

About RPE Calculator: Powerlifting

Hit the right weight on every set — including the ones nobody else calculates.

RPE Calculator is the free tool for powerlifters, strength athletes and anyone training with RPE-based programming. Enter one set and get your estimated 1RM and the exact weight for the next one. Then go further than any other calculator: paused, tempo, deficit and board work, priced properly.

THE VARIATION CALCULATOR (Pro)
Every other RPE calculator assumes you are doing the competition lift. Real training is not like that.

• Pick the variation: front, high bar, pin or box squat, close grip, Larsen, Spoto press, 1-, 2- or 3-board press (4, 8 and 12 cm), deficit deadlift, rack pull, snatch grip
• Add pauses anywhere in the range of motion — chest, 1 cm off, a few cm off, mid, in the hole, below the knee — and up to three in the same rep
• A pause suspended off the chest is priced harder than one resting on it, because it is: no contact, worst leverage
• Save the combinations your coach keeps prescribing, under a name
• Set the descent and the ascent, second by second — 3 seconds down and 3 seconds up is one row each
• The bar path only offers the stops you can actually make: with a board under the bar, the chest is not one of them
• Get one weight for your target reps and RPE — not a percentage you still have to work out
• Calibrate it: tell the app what you actually lifted on a variation and it learns your own coefficient, then remembers it for every future session

The model multiplies the leverage, the pauses and the tempo instead of adding them, and the pause curve is concave — the first second costs the most, the following ones progressively less, exactly like it feels under the bar. A slow ascent is charged more per second than a slow descent: refusing to accelerate out of the sticking point is harder than lowering under control.
