Formulas
Simple Mode:
Completion % = (Achievements Unlocked ÷ Total Achievements) × 100
Weighted PlayStation Trophy Mode:
Points Earned = (Bronze × 15) + (Silver × 30) + (Gold × 90) + (Platinum × 300)
Points Total = (Bronzetotal × 15) + (Silvertotal × 30) + (Goldtotal × 90) + (Platinumtotal × 300)
Weighted Completion % = (Points Earned ÷ Points Total) × 100
Assumptions & References
- PlayStation trophy point values are the official Sony weighting: Bronze = 15 pts, Silver = 30 pts, Gold = 90 pts, Platinum = 300 pts (source: PlayStation Network trophy system).
- Simple mode treats all achievements as equal weight, consistent with Xbox Achievements and Steam Achievements systems.
- Weighted mode reflects the relative difficulty/value of higher-tier trophies and gives a more accurate representation of overall game mastery.
- A Platinum trophy typically requires earning all other trophies in a game; only one Platinum is usually available per game.
- Completion grades are illustrative tiers and not official platform designations.
- All inputs must be non-negative whole numbers; earned counts cannot exceed available totals.
