Item Upgrade Material Estimator

How to Use This Tool

Follow these steps to generate an accurate material estimate for your in-game item upgrades:

1. Enter a name for the material you need (e.g. "Void Steel", "Mana Shard") or leave it blank to use the default "Material" label.
2. Input your item's current level and target upgrade level, making sure the target is higher than the current level.
3. Select your game's upgrade system type: Fixed Cost (guaranteed success per level) or RNG-Based (chance of failure per upgrade attempt).
4. If using RNG-Based, enter the success chance percentage for a single upgrade attempt (e.g. 75 for 75% chance).
5. Enter how many materials each upgrade level or attempt costs, then specify how many items you plan to upgrade.
6. Click the Calculate button to see your detailed material breakdown, or Reset to clear all inputs.

Formula and Logic

The calculator uses two core formulas depending on your selected upgrade system:

Fixed Cost Upgrades

For games where each upgrade level costs a set number of materials with 100% success rate:

Materials Per Item = (Target Level - Current Level) × Materials Per Level

Total Materials = Materials Per Item × Number of Items

RNG-Based Upgrades

For games where each upgrade attempt has a random chance of success, and failed attempts consume materials:

Expected Attempts Per Level = 100 ÷ Success Chance Percentage

Expected Attempts Per Item = (Target Level - Current Level) × Expected Attempts Per Level

Materials Per Item = ⌈Expected Attempts Per Item × Materials Per Attempt⌉

Total Materials = ⌈Materials Per Item × Number of Items⌉

All RNG values are rounded up to the nearest whole number to reflect that you cannot use partial materials in most games.

Practical Notes

Keep these gaming-specific factors in mind when using your estimate:

• Many games adjust upgrade costs or success rates in balance patches: always check your current game version's values before planning large material grinds.
• RNG-based estimates are statistical averages: you may need more or fewer materials than calculated due to variance, especially over small sample sizes.
• Some games have "pity" systems that guarantee success after a set number of failed attempts: add 1-2 extra materials per item to account for this if your game uses pity mechanics.
• Competitive games often have meta shifts that change which items are worth upgrading: prioritize materials for items that are currently viable in the meta to avoid wasting resources.
• For tabletop RPGs, upgrade costs may vary by GM ruling: confirm material costs with your game master before finalizing your estimate.

Why This Tool Is Useful

This estimator solves common pain points for gamers, designers, and streamers:

• Gamers can plan material grinds in advance, avoiding mid-grind shortages that stall progress.
• Game designers can balance upgrade systems by testing how material costs scale with item level and success rates.
• Streamers can share accurate upgrade costs with their audience instead of guessing live on stream.
• Competitive players can calculate exactly how many materials they need to upgrade gear before a tournament or ranked season.

Frequently Asked Questions

What if my game has a mix of fixed and RNG upgrade levels?

Calculate each segment of fixed and RNG levels separately, then add the total materials together. For example, if levels 1-10 are fixed and 11-15 are RNG, run two separate calculations and sum the results.

How do I account for material bonuses from buffs or events?

If you have a 20% material cost reduction buff active, multiply your final total materials by 0.8 (or the relevant reduction percentage) to get the adjusted estimate.

Can I use this for tabletop game item crafting?

Yes, the tool works for any system with per-level or per-attempt material costs. For tabletop games with variable material costs based on dice rolls, use the RNG mode with the average success chance of your dice roll.

Additional Guidance

Use these tips to get the most out of your material estimate:

• Always cross-check material costs with your game's official wiki or patch notes to ensure values are up to date.
• If you are upgrading multiple items of different levels, run a separate calculation for each item type to avoid overestimating or underestimating.
• For RNG-based systems, consider adding a 10-15% buffer to your total materials to account for unlucky streaks, especially if you are close to a ranked season or tournament deadline.
• Game designers can use the RNG mode to test how different success rates affect player grind time, helping balance progression pacing.
