Formula Used
Effective rating: if rating is below the soft cap, full rating is used. If rating is above the cap, extra rating is multiplied by post cap efficiency.
Rating percent: effective rating divided by rating required for one percent.
Total percent: base percent plus rating percent, then adjusted by secondary stat buff.
Weighted score: buffed core stats, weapon DPS, proc average, and converted stat percentages are multiplied by custom weights.
Throughput index: primary gain, weapon gain, critical effect, haste, mastery, versatility, uptime, target modifier, and proc value are multiplied together.
Survival index: buffed stamina becomes health, then versatility and avoidance increase practical durability.
How To Use This Calculator
Enter your current character values first. Add ratings from your character sheet. Adjust rating conversion values if your game version or private rules use different scaling.
Set soft caps when a stat loses value after a threshold. Enter post cap efficiency as a percentage. For example, seventy means extra rating gives seventy percent of normal value.
Change stat weights for your class, role, talents, and encounter. Press calculate. Review the score, converted percentages, and marginal priority table.
Use CSV for spreadsheet comparison. Use PDF for quick sharing or records.

Plan Stat Choices With Evidence
This calculator helps players compare character stats with a structured method. It does not replace logs, sims, or class guides. It gives a fast statistical view before you test gear. You can enter primary attributes, stamina, weapon damage, secondary ratings, buffs, soft caps, and custom weights. The tool then turns raw rating into percentages. It also applies post cap efficiency, so over stacked ratings lose value when you choose that setting.
Why Statistical Weighting Matters
Many players look only at item level. That can hide weak upgrades. A lower item may perform better when its stats fit your build. Weighted scoring solves that problem. Each stat receives a value based on your class, role, talents, and encounter style. A healer may value haste and mastery. A damage dealer may favor critical strike or versatility. A tank may push stamina, avoidance, and versatility. Because weights are editable, the calculator supports many roles without locking one rule set.
Reading The Results
The result area shows converted percentages, weighted contributions, throughput index, survival index, and stat priority. The priority table estimates the next one hundred rating points. That makes upgrade planning easier. If critical strike is already past the soft cap, another stat may win. If haste has higher efficiency, haste may become the next useful upgrade. The index values are best used for comparison. Run several gear sets and compare their scores. Use the CSV and PDF downloads to save results for later review.
Practical Gear Planning
Start with your current character sheet. Add buffs that are always active. Keep temporary effects separate by using proc value and uptime. Use realistic encounter uptime. A fight with long movement phases should not use perfect uptime. Then test one change at a time. Change one item, enchant, gem, or buff. Compare the final score and the marginal priority. This creates a clean decision trail. The calculator is not official game math. It is a planning model. Use it with raid logs and practical testing for stronger choices.
For best accuracy, keep one saved baseline. Update ratings after every upgrade. Record each result. Small changes become easier to explain when every input stays visible, repeatable, and exportable for your team.
FAQs
Is this calculator official game math?
No. It is a flexible planning model. Use it to compare builds, ratings, weights, and buffs. Always confirm important choices with in-game testing, combat logs, and class specific resources.
Can I change the rating conversion values?
Yes. Every rating conversion field is editable. This helps when levels, seasons, private rules, or custom assumptions change how much rating equals one percent.
What is post cap efficiency?
Post cap efficiency controls how much value rating keeps after a soft cap. If efficiency is seventy, extra rating above the cap gives seventy percent of normal value.
Why does the priority table use marginal value?
Marginal value estimates the benefit of the next stat gain. It is useful because a stat can become weaker after caps, buffs, or heavy stacking.
Should I use item level alone?
No. Item level is helpful, but stat mix matters. A lower item can be better when its ratings match your weights, caps, and role needs.
What does throughput index mean?
Throughput index is a comparison score. It combines primary stat, weapon value, critical effect, haste, mastery, versatility, uptime, target modifier, and proc average.
Can tanks use this calculator?
Yes. Tanks can raise stamina, versatility, avoidance, and survival related weights. The survival index also helps compare durability focused setups.
Why export CSV and PDF?
CSV works well for spreadsheets and repeated comparisons. PDF is useful for saving a clean result summary or sharing a build review.
