How to Use the Open World Completion Calculator
Aiming for 100% completion in an open world game? It can be hard to track areas, collectibles, quests, and achievements all at once. This calculator lets you enter total and completed counts for up to 5 categories, then calculates per-category completion rates, the overall completion percentage, and how many items remain.
Category names are fully editable β rename them to match your game exactly. The overall rate is calculated by combining all categories, so categories with more items have proportionally more weight on the overall score.
Completion Rate Formula
Category Rate = Completed Γ· Total Γ 100 | Overall = Sum of all completed Γ· Sum of all totals Γ 100
Frequently Asked Questions
No β categories with more items naturally have more influence on the overall rate. A category of 200 collectibles counts more than one of 50 areas. This mirrors how most game completion systems work.
Use this calculator for one game at a time. For multiple playthroughs, just update the completed counts as your progress changes.
