What is the EVE Online Reprocessing Calculator?

The EVE Online Reprocessing Calculator is an essential tool for any capsuleer involved in mining, industry, or market trading in New Eden. It allows players to accurately predict the amount and value of minerals they will receive when reprocessing raw ore, ice, or salvage. Reprocessing, often referred to as refining, is the process of converting these raw materials into their constituent minerals, which are then used for manufacturing, research, or sold on the market.

This EVE Online Reprocessing Calculator takes into account a multitude of factors that influence your final yield, including your character’s skills, active implants, the bonuses provided by the reprocessing facility (station or Upwell structure), and any applicable taxes. By providing a precise estimate of mineral output and market value, it empowers players to make informed decisions about what to mine, where to reprocess, and when to sell.

Who Should Use the EVE Online Reprocessing Calculator?

• Miners: To determine the most profitable ores to extract and the best locations to reprocess them.
• Industrialists: To calculate the true cost of minerals obtained through reprocessing versus buying them directly from the market.
• Traders: To identify arbitrage opportunities by comparing raw ore prices with the value of their reprocessed minerals.
• New Players: To understand the mechanics of reprocessing and how to efficiently train skills for better yields.
• Corporation Leaders: To set fair reprocessing service fees for their members or evaluate the profitability of deploying reprocessing structures.

Common Misconceptions about EVE Online Reprocessing

• “All stations give the same yield”: Incorrect. NPC stations have a base yield, but Upwell structures (Citadels, Engineering Complexes, Refineries) with specific service modules and rigs can offer significantly higher yields, especially in low-security or null-security space.
• “Only Reprocessing skill matters”: While crucial, it’s not the only skill. Specific ore processing skills (e.g., Veldspar Processing), Reprocessing Efficiency, and even certain implants play a vital role in maximizing your EVE Online Reprocessing Calculator results.
• “Higher security status always means better yield”: Not necessarily. While high-sec offers safety, the highest reprocessing yields are often found in 0.0 null-security space or wormholes within well-rigged Refineries, due to system bonuses and advanced rigs. However, these areas come with increased risk.
• “Reprocessing is always profitable”: Not true. Market fluctuations can sometimes make selling raw ore more profitable than reprocessing it, especially if your skills are low or taxes are high. Always use an EVE Online Reprocessing Calculator to check current profitability.

EVE Online Reprocessing Formula and Mathematical Explanation

The core of the EVE Online Reprocessing Calculator lies in its formula, which combines various bonuses and penalties to determine your final mineral yield. Understanding this formula is key to optimizing your reprocessing operations.

Step-by-Step Derivation of the Reprocessing Yield

The reprocessing yield in EVE Online is calculated multiplicatively, meaning each bonus factor builds upon the previous ones. The base yield for raw ore in an NPC station is typically 50%.

1. Base Yield: Starts at 50% for raw ore in NPC stations. This can be higher in certain Upwell structures.
2. Structure & Implant Bonus: The base yield is first modified by the facility’s bonus (from rigs, service modules, system security) and any active reprocessing implants.
   Base Yield * (1 + Structure Bonus / 100) * (1 + Implant Bonus / 100)
3. Skill Multipliers: Your character’s skills then further multiply this value.
   • Reprocessing Skill: Each level adds 3% to the base yield.
   • Specific Ore Reprocessing Skill: Each level adds 2% to the base yield for that specific ore type.
   • Reprocessing Efficiency Skill: Each level adds 2% to the base yield.

   Skill Multiplier = (1 + Reprocessing Skill * 0.03) * (1 + Specific Ore Reprocessing Skill * 0.02) * (1 + Reprocessing Efficiency Skill * 0.02)

4. Total Raw Yield Percentage: This is the percentage of minerals you would receive before any taxes.
   Total Raw Yield % = Base Yield * (1 + Structure Bonus / 100) * (1 + Implant Bonus / 100) * Skill Multiplier
5. Reprocessing Tax: Finally, any reprocessing tax charged by the facility is applied as a reduction to the total raw yield.
   Final Yield % = Total Raw Yield % * (1 - Reprocessing Tax / 100)

The minerals produced are then calculated by multiplying the base mineral content of the ore by this Final Yield % and the Ore Quantity.

Key Factors That Affect EVE Online Reprocessing Results

Maximizing your reprocessing profits in EVE Online requires a deep understanding of the various factors that influence your yield. The EVE Online Reprocessing Calculator helps you model these effects.

1. Character Skills:
   • Reprocessing (Rank 6): The foundational skill, increasing base yield by 3% per level. Essential for any serious reprocessor.
   • Specific Ore Processing Skills (e.g., Veldspar Processing, Crokite Processing) (Rank 3): These skills increase the yield of specific ore types by 2% per level. Crucial for specializing in certain ores.
   • Reprocessing Efficiency (Rank 4): Another multiplicative skill, adding 2% per level to your yield.
   • Science/Industry Support Skills: While not directly affecting yield, skills like Industry or Production Efficiency can indirectly help by reducing manufacturing costs if you plan to use the minerals yourself.
2. Implants:

   Certain implants, particularly the Poteque ‘Prospector’ Reprocessing RX series (e.g., RX-802, RX-804), provide direct percentage bonuses to your reprocessing yield. These are often expensive but offer a significant boost, especially for high-value ores. The EVE Online Reprocessing Calculator allows you to factor these in.

3. Reprocessing Facility (Station/Structure):
   • NPC Stations: Offer a base yield (usually 50% for raw ore) with no inherent bonuses, but often high taxes.
   • Upwell Structures (Refineries, Engineering Complexes, Citadels): These player-owned structures can be fitted with Reprocessing Service Modules and Reprocessing Rigs (T1 or T2) to significantly increase yield. T2 rigs offer the best bonuses.
   • System Security Status: Refineries in low-security, null-security, and wormhole space receive additional bonuses to reprocessing yield, making these areas highly lucrative for reprocessing, albeit riskier.
4. Reprocessing Tax/Fees:

   Most public reprocessing facilities, whether NPC stations or player-owned structures, charge a tax on the reprocessed minerals. This tax can range from 0% (in your own structure or a friendly corp’s structure) to 10% or more. This is a direct reduction to your final ISK profit and is a critical input for the EVE Online Reprocessing Calculator.

5. Ore Type and Base Mineral Composition:

   Different ores yield different types and quantities of minerals. High-end ores like Arkonor, Bistot, and Crokite contain valuable minerals like Megacyte and Morphite, making them highly profitable to reprocess, especially with high yields. The EVE Online Reprocessing Calculator accounts for the specific mineral breakdown of each ore.

6. Market Prices of Minerals:

   The final ISK value of your reprocessed minerals is entirely dependent on their current market prices. These prices fluctuate constantly based on supply and demand. Always use up-to-date mineral prices in the EVE Online Reprocessing Calculator to get an accurate profit estimate. A sudden drop in Tritanium price can drastically affect the profitability of common ores.

Frequently Asked Questions (FAQ) about EVE Online Reprocessing

Q: What is the maximum reprocessing yield I can achieve in EVE Online?

A: With max skills (Reprocessing V, specific ore processing V, Reprocessing Efficiency V), a +4% implant, and reprocessing in a fully rigged T2 Refinery in 0.0 null-sec (6% structure bonus) with 0% tax, you can achieve yields upwards of 88-90% for raw ore. The EVE Online Reprocessing Calculator can help you verify this for specific setups.

Q: Is it always better to reprocess than to sell raw ore?

A: Not always. It depends on your skills, the reprocessing facility’s bonuses and taxes, and the current market prices of both the raw ore and its constituent minerals. Use the EVE Online Reprocessing Calculator to compare the ISK value of selling raw ore versus the net mineral value after reprocessing and taxes.

Q: How do I get a 0% reprocessing tax?

A: To achieve 0% reprocessing tax, you typically need to reprocess in an Upwell structure (Refinery, Engineering Complex, Citadel) owned by your own corporation or alliance, where the owner has set the tax to 0% for members. Public structures almost always charge a fee.

Q: What are the best skills for reprocessing?

A: The core skills are Reprocessing V, Reprocessing Efficiency V, and the specific ore processing skills (e.g., Veldspar Processing V, Scordite Processing V) for the ores you frequently handle. These are crucial for maximizing your EVE Online Reprocessing Calculator results.

Q: Do security status and system type affect reprocessing yield?

A: Yes, indirectly. While NPC stations don’t get security status bonuses, Upwell Refineries in low-security, null-security, and wormhole space receive additional yield bonuses, making them more efficient than high-security counterparts, assuming they are properly rigged. This is factored into the “Structure Bonus” input of the EVE Online Reprocessing Calculator.

Q: Can I reprocess salvage or ice with this calculator?

A: This specific EVE Online Reprocessing Calculator is primarily designed for raw ore. While the underlying formula is similar, salvage and ice have different base yields and mineral/component compositions. You would need specific data for those items to use this calculator accurately, or a dedicated calculator for them.

Q: Why are my reprocessing yields so low?

A: Common reasons for low yields include low skill levels, no reprocessing implants, using an un-rigged or poorly-rigged facility, or reprocessing in an NPC station with high taxes. Use the EVE Online Reprocessing Calculator to identify which factors are most impacting your yield.

Q: How often should I update mineral prices in the EVE Online Reprocessing Calculator?

A: Mineral prices in EVE Online can fluctuate daily, or even hourly during peak market activity. For critical decisions, it’s best to update prices just before you plan to reprocess or sell. For general planning, weekly or bi-weekly updates might suffice.
