A squat multiple only compares under matched conditions
The same lifter squats very different numbers depending on where the bar sits and how deep the rep goes. A low-bar squat usually moves more weight than a high-bar squat, and shaving a little depth raises the figure again. That limits how far a bodyweight multiple travels between people, and makes your own record, measured with the same stance and the same depth over time, the more useful comparison. This page estimates a 1RM from the weight and reps you enter, then returns the multiple and the weight left to the 1x, 1.5x, 2x and 2.5x milestones.
Both the Epley and the Brzycki formula are applied, and the milestone table runs off the Epley figure, as the label states (as of October 2026). Add a deadlift 1RM and the page divides the squat by the deadlift.
The 80-91% comparison band comes from competition-record analyses and coaching material. It is convention, not an official standard: sources mix ratios measured against the squat with ratios measured against the deadlift, quote medians alongside coaching targets, and therefore disagree with one another, and all of them are secondary analyses rather than peer-reviewed research. Several also note that bodyweight, limb length and technique move the figure.
No level or grade is assigned, and no next target load is prescribed. Failing a squat leaves the bar on your back, so estimating from a set of around five reps is safer than testing a true max. If you do go for a maximum, set the safety bars to the right height first and have a spotter.
Frequently asked questions
Better to settle on one. The two positions move different loads, so mixing them makes the multiple jump around. Pick the variation you want to track and keep the depth standard consistent as well.
No. The strength grade tables quoted online are percentiles of lifts that users of one site uploaded about themselves, and different sites place the same weight at different levels. With no official standard, this page stops at multiples and milestones.
It is not unusual. Build and event-specific skill can flip the order of the two lifts. A ratio above 100% simply means the squat is the heavier of the two, which is not wrong on its own.
