Calculate your Wilks coefficient to compare powerlifting performances across different weight classes
Wilks Calculator is the free tool every serious powerlifter keeps on their phone for one reason: it instantly turns your raw total into a fair Wilks score that finally answers who is truly the strongest. Size stops mattering. Gender stops mattering. A 58 kg woman can pull ahead of a 120 kg male lifter and the Wilks points will prove it without argument. Enter your bodyweight in kg, your total (or individual squat, bench press and deadlift), pick male or female and in seconds you get the one honest score that has ranked powerlifters across different bodyweights and generations since Robert Wilks created it.
A Wilks calculator is a formula calculator that turns your raw total into a fair Wilks score. It lets every powerlifter see who is truly strongest no matter bodyweight or gender.
The Wilks score (or Wilks points) is a number that measures relative strength. You take your competition total in kilograms (squat + bench press + deadlift) and multiply by a special Wilks coefficient that changes with bodyweight and sex. Heavier lifters get a smaller coefficient; lighter lifters get a bigger one — creating a single score that shows absolute strength adjusted relative to bodyweight.
The Wilks calculator was developed by Robert Wilks, CEO of Powerlifting Australia, to let lifters of different bodyweights compete on equal terms. Before Wilks, heavier lifters always dominated. The formula gives every athlete (men and women) a level playing field and is still widely used even after some federations moved to IPF Points or DOTS.
When you calculate your Wilks after every meet or big training day you see real improvement that raw kilos hide. You can compare yourself to elite powerlifters, friends, or your old self. A score above 300 is solid, 400 is very strong, and 500+ is world-class for both male and female powerlifters.
Pick male or female first — the Wilks coefficient changes completely between men and women.
Type your exact bodyweight in kg (morning weigh-in, same as meet day). Every 0.5 kg changes the coefficient and can move your score by 2–5 points.
Enter your best lifts separately in kilograms and the calculator adds them into the official total for you.
After a meet, just type your total (e.g., 550 kg) and skip the individual lifts — fastest method.
Your raw total is multiplied by the exact Wilks coefficient for your bodyweight and gender. Result: your honest Wilks score.
300+ = strong local lifter 350–399 = national level 400–450 = international 450–500 = elite 500+ = all-time great
Score = Total × 500 / (a + b×BW + c×BW² + d×BW³ + e×BW⁴ + f×BW⁵)
Coefficients (a–f) are fixed constants specific to men.
Score = Total × 500 / (a + b×BW + c×BW² + d×BW³ + e×BW⁴ + f×BW⁵)
Women use a completely different set of coefficients.
The denominator produces the Wilks coefficient (0.5–1.0 range). Lighter lifters get a higher multiplier, heavier lifters get a lower one — creating the fair comparison.
The original Wilks (2004 version) is still the most widely accepted and used. Some sites use slight variations or rounding differences — always choose “Original Wilks” for consistency with historical rankings.
Raw kilos lie to lighter lifters and flatter heavier ones. Your Wilks score reveals your true starting point so you train for your actual relative strength level.
350 Wilks points = nationally competitive 450 = international class — true for every weight class and gender.
See exactly how many kilos a realistic 20–30 point jump requires for your size instead of chasing impossible raw total leaps.
A 10-point increase at the same bodyweight is pure strength gain — Wilks cuts through weight-class changes and water cuts.
Shows when you’re already pushing elite relative strength for your size and need to back off before injury.
One click ends every “who’s stronger” debate in the gym — no more arguments.
Programs built on Wilks match your actual strength level instead of copying super-heavyweights.
Punch in total + bodyweight → instant world-wide ranking before you even unrack the bar.
Beginners train for their own relative strength from day one. Pros know exactly how many Wilks points a new program must deliver.
A Wilks calculator is more than a tool — it is the final judge that never lies. Raw totals impress, but only the Wilks score tells the real story of strength. It gives the 58 kg woman and the 120 kg man the same chance to stand on the same podium. Keep it open on your phone, feed it your numbers after every big session, and watch the points climb. That rising score is the only proof you ever need that you are getting stronger — not just bigger.
A free online tool that converts your powerlifting total into a Wilks score so lifters of any bodyweight and gender can be compared fairly.
Wilks Score = Total kg × Wilks Coefficient (coefficient derived from bodyweight and gender via 6th-order polynomial).
300+ = strong 350+ = very good 400+ = national level 450+ = international/elite 500+ = all-time great
Yes — completely separate coefficients.
1. Increase your total 2. Stay as light as possible in your class 3. Train the big three hard 4. Cut water only if lifts stay strong.
A multiplier (≈0.5–1.0) that’s higher for lighter lifters, making the comparison fair.
Some use old coefficients, rounding differences, or switched to IPF Points/DOTS. Choose “Original Wilks” for consistency.
