What is EVE Online Reprocessing?
EVE Online reprocessing is the crucial industrial process of converting raw ore or ice into usable minerals, which are the fundamental building blocks for almost everything in the game, from ships and modules to structures and ammunition. It's a cornerstone activity for any aspiring industrialist or miner looking to maximize their profits in the vast universe of New Eden.
Who should use an EVE Online reprocessing calculator? This tool is invaluable for:
- Miners: To understand the true value of their hauls before selling raw ore or reprocessing it themselves.
- Industrialists: To calculate the cost of materials for manufacturing and ensure profitability.
- Structure Owners: To set competitive reprocessing tax rates and attract users to their Upwell Structures.
- Traders: To identify arbitrage opportunities between raw ore and refined minerals.
Common misunderstandings about EVE Online reprocessing often revolve around the final yield percentage. Many players mistakenly believe that having "100% Reprocessing" means they get all minerals back. In reality, the base yield for raw ore is 50%, and all bonuses (skills, implants, structures, rigs, standings) multiply this base, never reaching 100% of the *original* mineral content in the ore. The reprocessing tax also directly reduces the final mineral output, not just the ISK value.
EVE Online Reprocessing Formula and Explanation
The EVE Online reprocessing yield calculation can seem complex due to the various factors involved. Here's a simplified breakdown of the formula used in this EVE Online reprocessing calculator:
First, we establish the base yield and apply skill bonuses:
Base Yield % = 50% (for raw ore)
Reprocessing Skill Factor = Reprocessing Skill Level * 0.03
Scrapmetal Processing Skill Factor = Scrapmetal Processing Skill Level * 0.02
Initial Yield % = Base Yield % * (1 + Reprocessing Skill Factor + Scrapmetal Processing Skill Factor)
Next, we incorporate additional bonuses from implants, structures, rigs, and standings:
Implants Factor = Implant Bonus Percentage / 100
Structure Factor = Structure Bonus Percentage / 100
Rig Factor = Rig Bonus Percentage / 100
Standing Factor = Standing Bonus Percentage / 100
Effective Reprocessing Percentage (before tax) = Initial Yield % * (1 + Implants Factor + Structure Factor + Rig Factor + Standing Factor)
Finally, the reprocessing tax is applied:
Reprocessing Tax Rate = Reprocessing Tax Percentage / 100
Actual Yield % (after tax) = Effective Reprocessing Percentage (before tax) * (1 - Reprocessing Tax Rate)
This Actual Yield % is then multiplied by the base mineral quantities found in the ore to determine the final mineral output. The total ISK value is the sum of (reprocessed mineral quantity * mineral unit price) for all minerals.

Key Factors That Affect EVE Online Reprocessing
Achieving optimal EVE Online reprocessing yields requires understanding and maximizing several key factors:
- Skill Levels: Your Reprocessing and Scrapmetal Processing skills are foundational. Training them to V is the first and most impactful step to increasing your mineral yield. These skills directly multiply your base yield.
- Implants: Reprocessing implants, such as the Priceless Reprocessing Implant or various grades of ORE Reprocessing Implants, provide direct percentage bonuses. While costly, they are essential for high-end reprocessing.
- Structure Type & Service Module: Upwell Structures equipped with a Reprocessing Service Module are critical. Raitarus, Azbels, and Sotiyos offer a 50% bonus, while the Athanor, a dedicated refinery, provides an even higher 54% bonus. NPC stations offer a much lower base yield and bonus.
- Reprocessing Rigs: Installing Reprocessing Efficiency Rigs (Type I or Type II) in your Upwell Structure further boosts the yield. Type II rigs offer a slightly higher bonus but come with a higher cost.
- Faction/Corp Standings: High standings with the faction or corporation owning an NPC station can provide a small but noticeable bonus to reprocessing yield. This is less relevant for player-owned structures.
- Reprocessing Tax Rate: This is a direct percentage reduction from your final mineral output, set by the structure owner. Always seek out structures with low or zero taxes for maximum profit.
- Mineral Prices: The market value of minerals fluctuates constantly. Monitoring EVE Online mineral prices is paramount, as even a perfect reprocessing setup will yield low ISK if the minerals are cheap. This calculator allows you to input current prices for accurate valuation.
Frequently Asked Questions about EVE Online Reprocessing
- Q: What's the best reprocessing yield I can get in EVE Online?
- A: With max skills, implants, a T2 rigged Athanor, and 10.0 standings, you can achieve around 87-88% actual yield (before tax). This means you get 87-88% of the *potential* minerals in the ore, not 87-88% of the raw ore's volume.
- Q: How do I improve my reprocessing skills?
- A: Train the "Reprocessing" skill and the "Scrapmetal Processing" skill (for ore) to Level V. Also, train specific ore reprocessing skills (e.g., Veldspar Processing) to Level V for each ore type you frequently reprocess.
- Q: Does system security status affect reprocessing in player structures?
- A: No, system security status primarily affects the base reprocessing yield in NPC stations. Player-owned Upwell Structures have a fixed base yield modifier, regardless of the system's security status.
- Q: Why are my calculator results different from in-game or other tools?
- A: Discrepancies can arise from several factors: slight differences in formula implementation, rounding errors, outdated mineral prices, specific game mechanics not precisely modeled (e.g., specific ore compression impacts), or incorrect input values. Ensure your mineral prices are up-to-date.
- Q: What is the "base yield" of ore in EVE Online?
- A: The theoretical base yield for raw ore is 50%. All skills, implants, and structure bonuses then multiply this base yield to arrive at your effective reprocessing percentage.
- Q: How does reprocessing tax work?
- A: The reprocessing tax is applied as a percentage reduction to your final reprocessed mineral quantity. For example, a 10% tax means you receive 90% of the minerals you would have otherwise obtained.
- Q: Can I reprocess compressed ore?
- A: Yes, compressed ore can be reprocessed just like raw ore. The mineral yield calculations are the same; compression is primarily for logistics and reducing volume.
- Q: What's the difference between Reprocessing and Scrapmetal Processing?
- A: "Reprocessing" is a general skill that provides a bonus to all reprocessing. "Scrapmetal Processing" is a specialized skill that provides an additional bonus specifically when reprocessing ore and scrap metal, making it crucial for miners and industrialists.
