What Is The Ore Chance Calculator?
The Ore Chance Calculator is a free tool for The Forge (Roblox) that calculates precise ore drop probabilities from any rock type. Enter your pickaxe power and luck stats to see which rocks are mineable, view base ore drop rates (1/N format), apply rock luck multipliers, and get your final ore drop chance after all pickaxe luck bonuses. Perfect for finding the best rocks for specific ores and optimizing your mining efficiency.
This pickaxe luck calculator uses verified game data to show exact ore probabilities, helping you understand why some ores drop more frequently from certain rocks. Combine it with The Forge Calculator to plan your complete crafting strategy, or check the complete ore guide for detailed ore locations and crafting recipes.
How The Ore Chance Calculator Works
Select your pickaxe from the dropdown menu. Each pickaxe in The Forge has a base power (mining damage) and base luck percentage. The ore chance calculator automatically determines which rocks are mineable based on your pickaxe power requirement, highlighting available mining options.
Configure your total pickaxe luck by entering your runes luck bonus percentage and selecting active buffs. Available luck bonuses include Achievement luck, Angel/Archangel Race (+30%), Luck Potion (+20%), Totem (+25%), Christmas Potion (+25%), Fungi Potion (+15%), and Weekend Boost (+100%). The calculator sums all bonuses to calculate your final pickaxe luck multiplier.
Use the ore filter to search for a specific ore type. The calculator filters the rock list to show only rocks that can drop your selected ore, automatically sorted by highest drop probability. This feature helps you quickly identify the best rock type and mining location for any target ore in The Forge.
Expand any rock card to view detailed ore drop probability calculations. Each ore displays its base drop rate (1/N), the probability after applying the rock luck multiplier, and your final ore drop chance after all pickaxe luck bonuses. Results show both minimum and maximum spawn count probabilities. Rocks are automatically marked as "Mineable" or "Not mineable" based on your current pickaxe power level.
Frequently Asked Questions
How accurate is the Ore Chance Calculator?
The calculator uses the same data tables and formulas that power the in-game mining system. All drop rates, rock luck multipliers, and pickaxe stats are based on verified game data, ensuring accurate probability calculations for your mining strategy.
What is the difference between rock luck and pickaxe luck?
Rock luck is a multiplier specific to each rock type (e.g., x50) that boosts all ore drop chances from that rock. Pickaxe luck is your personal stat (from your pickaxe base, runes, achievements, and buffs) that further multiplies those chances. Both work together to determine your final ore drop probability.
Can I use this to find the best rock for a specific ore?
Yes. Use the ore filter dropdown to select a specific ore, and the calculator will show only rocks that can drop it, sorted by the best drop chances. This helps you quickly identify which rock type gives you the highest probability for your target ore.
Why are some rocks marked as "Not mineable"?
Each rock has a minimum pickaxe power requirement. If your pickaxe power is below that threshold, you cannot mine that rock in-game, so the calculator marks it as not mineable. Upgrade your pickaxe or check the rock requirements to unlock more mining options.
How do buffs like Luck Potion or Weekend Boost affect results?
All active buffs (Luck Potion, Totem, Weekend Boost, etc.) add to your total pickaxe luck percentage. The calculator combines your base pickaxe luck, runes luck, achievement luck, and all active buffs to calculate the final luck multiplier that affects every ore drop chance.
Where can I find more information about ores and mining?
Check the complete ore guide in the wiki to see where each ore can be found, their uses in crafting, and detailed drop locations. You can also use The Forge Calculator to see how these ores affect your crafting results.
