Calculator Inputs
Formula Used
Rank Factor = (Current Rank + 1) / 9
Positive Count Factor = 1.30 for one positive, 1.10 for two positives, and 0.90 for three positives.
Positive Value = Benchmark × Disposition × Roll Quality × Positive Count Factor × Negative Boost Factor × Rank Factor.
Negative Value = Negative Benchmark × Disposition × Roll Quality × Negative Factor × Rank Factor.
Net Weighted Score = Sum of positive weighted values − negative penalty.
Score Percent = Net Weighted Score / Potential Positive Score × 100.
This is an estimator. Change benchmark values and weights to match your own build logic.

About This Riven Mod Stat Calculator
A Riven mod can change a weapon in a strong way. It may add damage, critical chance, multishot, status chance, elemental power, or other useful values. This calculator helps you estimate those values with clear inputs. It is made for review, comparison, and record keeping. It does not claim to copy a hidden game table. Instead, it uses editable benchmark values and transparent multipliers.
Why Stat Mix Matters
Riven rolls often feel hard to compare. Two positive stats can look larger than three positive stats. A harmless negative can also make the positive lines stronger. Disposition then raises or lowers the total range. Because of this, a simple total is not enough. The calculator gives every stat a weight. Strong stats can receive higher weights. Weak or unwanted stats can receive lower weights. This makes the final score more practical.
Using The Score
The score is a guide, not a trade price. Start with the weapon name and disposition. Choose the mod rank and roll quality. Enter each positive stat name, benchmark value, and weight. Then add a negative stat if the roll has one. Use severity to decide how harmful that negative line is. A harmless negative can have a small severity. A bad negative can have a large severity.
Roll Planning
The tool also shows a capacity estimate and a reroll cost estimate. These fields are editable, so you can match your own planning method. Use the CSV download when you want spreadsheet records. Use the PDF button when you want a simple report. The example table shows typical review cases. Replace those numbers with your own target build.
Best Practice
Compare several rolls before making a decision. Look at net weighted value, grade, and notes together. A high number is not always best. The best Riven supports the weapon build you actually use. For example, critical chance is less useful on a weapon with poor critical stats. Status chance is better when the weapon applies effects often. Always judge the result beside your build, not alone. Keep old outputs in one folder. Over time, those records show which stat patterns give steady value for your preferred weapons and later builds too.
FAQs
What does this calculator estimate?
It estimates Riven stat values, weighted score, grade, capacity drain, and reroll cost planning values. It helps compare rolls with the same method.
Is this an exact game formula?
No. It is a transparent estimator. You can adjust benchmark values, weights, roll quality, and boost settings to fit your preferred method.
Why do two positive stats sometimes score well?
Fewer positive lines may give larger individual values. The calculator reflects this with a stronger positive count factor for fewer positive stats.
Why can a negative stat improve the result?
A negative line can raise positive stat strength. If the negative is harmless for your weapon, the roll may become more valuable.
What is negative severity?
Negative severity measures how harmful the negative stat is. Use low severity for harmless negatives. Use high severity for build-breaking negatives.
How should I set stat weights?
Give important stats higher weights. For example, use higher weights for critical stats on critical weapons, or status stats on status weapons.
Can I export the result?
Yes. Use the CSV button for spreadsheet data. Use the PDF button after calculation for a simple printable result summary.
Does the score decide market price?
No. Market price depends on demand, weapon popularity, platform, timing, and buyer preference. The score only helps compare stat quality.
