The Wilks score normalizes a lifter’s total by bodyweight. First, a coefficient is calculated from bodyweight using a fifth‑order polynomial.
Wilks Score = Total(kg) × Coefficient
W is bodyweight in kilograms. Coefficients differ for male and female categories.

What the Wilks Score Represents
The Wilks score is a normalization method that lets coaches compare strength totals across different bodyweights. It multiplies a lifter’s total by a coefficient derived from bodyweight, producing a single number that helps rank performances in open meets, team trials, and mixed-weight training groups.
Inputs That Influence Your Score
Your sex category, bodyweight, and total lifted drive the calculation. Because the coefficient changes nonlinearly with bodyweight, a small change in weigh‑in mass can shift the score more than expected. For consistent tracking, use the same weigh‑in conditions and record the unit system you used.
Interpreting Coefficient and Total
The coefficient reflects how bodyweight adjusts expected strength potential within the model. A higher coefficient typically appears at lower bodyweights, meaning each kilogram of total adds more points. The total is still the primary performance lever: improving technique, attempt selection, and fatigue management generally moves the score faster than cutting weight.
Using Results for Training Decisions
Treat the score as a trend indicator, not a complete athlete profile. Pair it with objective data such as volume load, rep PRs, and bar‑speed targets. When the score stalls, review recovery inputs, weekly stress balance, and lift-specific weaknesses. In peaking blocks, use score projections to validate opener choices and risk levels.
Reporting and Comparing Athletes
For fair comparisons, export results to CSV or PDF and include the time stamp, bodyweight, coefficient, and total in kilograms. When comparing across sessions, note rule differences, equipment, and meet conditions. The history table supports quick auditing and helps identify whether changes came from strength gains or weigh‑in variation.
In this calculator, the coefficient comes from a fifth‑order polynomial with different constants for male and female categories. Scores compare best when rules and equipment are similar, because judging depth, deadlift hitching calls, and supportive gear can inflate totals.
You may enter a meet total or the three lifts to cross‑check your logbook. Use rounding for cleaner reports, then export CSV or PDF with timestamp, bodyweight, total in kilograms, coefficient, and score. Over time, aim for steady score gains while keeping bodyweight changes deliberate rather than reactive. Across training blocks.
FAQs
Which units should I use?
Use whichever matches your logbook. The calculator converts pounds to kilograms internally, so the score is consistent. Keep the same unit choice when tracking progress over time.
Should I enter a total or the three lifts?
If you already know your meet total, enter it for speed. If you track each lift, use the breakdown option to verify the sum and spot which lift most affects your overall score.
Why is the score zero or missing?
A zero result usually means bodyweight or total was not greater than zero, or the inputs produced an invalid coefficient. Check for empty fields, typos, and negative values, then submit again.
Does a small bodyweight change matter?
Yes. The coefficient is bodyweight‑dependent, so weigh‑in changes can move the score even if your total stays the same. For fair comparisons, use meet‑day bodyweight and similar weigh‑in conditions.
Is this the only scoring method used in strength sports?
No. Some organizations use updated point systems. This calculator uses classic Wilks coefficients, so compare results only with other lifters scored the same way for the same rule set.
How do I export results cleanly?
After calculating, download CSV for spreadsheets or PDF for sharing. The exports include timestamp, bodyweight, total in kilograms, coefficient, and score, plus your recent history for quick review.
