Know the number, then move it — the coach programs around your weakest of the three lifts.
What is a Wilks score?
A Wilks score converts a powerlifting total into a single number that can be compared across bodyweights. Bigger lifters move more absolute weight, so a raw total says little on its own; the coefficient scales it so a 59 kg lifter and a 120 kg lifter can be ranked on the same list.
How this calculator works
Wilks (2020) divides 600 by a fifth-order polynomial of your bodyweight in kilograms, then multiplies by your total. DOTS uses the same idea with 500 and a fourth-order polynomial. IPF GL points use an exponential curve, 100 ÷ (a − b·e^(−c·bodyweight)), scaled so an all-time world-best performance lands near 100. All three take your competition total: squat + bench + deadlift, best successful attempt in each.
Wilks vs DOTS vs IPF GL — which one counts?
The IPF and its national affiliates rank lifters on IPF GL points, which replaced the older IPF formula in 2020. DOTS is the default at most non-IPF federations and in online rankings, because its curve treats heavier lifters more fairly than the original 1994 Wilks. Wilks itself is still the number most gyms and lifters quote in conversation, and the 2020 revision is the version you want — its scores run higher than the 1994 original, so never compare the two directly.
Using your score
A relative-strength score is most useful as a trend line. Recalculate it after every meet or mock meet: if your total climbs while your bodyweight holds, the score moves and you got stronger, not just heavier. If it stalls, the answer is usually in the lift that lags the other two.
