A) What is an Arc Calculator FoE?
An Arc Calculator FoE is an essential tool for players of Forge of Empires (FoE) who own or frequently interact with the "Arc" Great Building. The Arc is one of the most powerful Great Buildings in the game, providing a significant bonus to rewards received from other players' Great Buildings.
This calculator helps players make informed decisions about their Forge Point (FP) investments. It predicts the optimal FP contribution needed to secure a specific spot (P1, P2, P3, P4, P5) on another player's Arc, calculates the resulting FP profit or loss, and details the Blueprint (BP), Medal, and Goods rewards. It's particularly vital for those participating in "1.9 threads" or other guild-based FP exchange strategies.
Who should use this Arc Calculator?
- Arc Owners: To understand the value of their GB and communicate fair prices for spots.
- Investors: To ensure they are making profitable contributions and maximizing their returns.
- Guild Leaders: To help members understand optimal strategies and maintain fair play in FP exchanges.
Common Misunderstandings
Many players confuse the Arc's own bonus with their personal Arc's bonus. The target Arc's level determines the base FP rewards and its multiplier for those rewards. Your own Arc's bonus, however, affects the FPs you get back *on your own contribution*. This calculator accounts for both to provide an accurate net profit.
Another common point of confusion is the "1.9" factor. This isn't a game mechanic but a community-established profit margin for the Arc owner. Our Arc Calculator FoE uses this common factor to determine recommended contributions.
B) Arc Calculator FoE Formula and Explanation
The core of the Arc Calculator FoE lies in understanding how Forge Points are distributed and how your own Arc's bonus impacts your net gain. The calculation aims to determine the "recommended contribution" for a spot in a typical "1.9 thread" scenario, and then your personal profit from that contribution.
The formula can be broken down into several steps:
- Target Arc's Bonus Multiplier: This is derived from the Target Arc's level. The game uses specific formulas for different level ranges.
- Base FP Reward: Each spot (P1-P5) on an Arc has a base FP reward, which depends solely on the Target Arc's level. This is a fixed value from game data.
- Actual FP Reward from Arc: This is the Base FP Reward multiplied by the Target Arc's Bonus Multiplier. This is what the investor *receives* from the Arc itself.
- Recommended Contribution (in a 1.9 thread): In a standard "1.9 thread," the owner aims for a 90% profit (1.9x return) from investors. The recommended contribution is typically calculated as `Ceiling(Actual FP Reward from Arc / 1.9)`. This is the amount of FPs an investor is expected to put in.
- Your Self-Bonus on Contribution: If you have your own Arc, you receive FPs back on *any* FPs you spend. This is `Recommended Contribution * (Your Arc Bonus % / 100)`.
- Total FPs Received: This is the sum of the Actual FP Reward from the Target Arc and Your Self-Bonus.
- Net FP Profit: This is `Total FPs Received - Recommended Contribution`. A positive number indicates profit, a negative number indicates a net cost.

C) Practical Examples
Let's illustrate how the Arc Calculator FoE works with a couple of real-world scenarios:
Example 1: Experienced Investor in a High-Level Arc
- Inputs:
- Target Arc Level: 120
- Your Arc Bonus: 133% (equivalent to L120 Arc)
- Target Spot: P1
Calculation & Results:
At Level 120, the Target Arc has a bonus multiplier of 2.33. The base FP reward for P1 at this level is 300 FPs.
- Actual FP Reward from Arc: 300 FPs * 2.33 = 699 FPs
- Recommended Contribution (1.9 thread): Ceiling(699 / 1.9) = 368 FPs
- Your Self-Bonus on Contribution: 368 FPs * (133 / 100) = 489 FPs
- Total FPs Received: 699 FPs + 489 FPs = 1188 FPs
- Net FP Profit: 1188 FPs - 368 FPs = 820 FPs (Profit!)
- Other Rewards: 2 BPs, 3000 Medals, 150 Goods
In this scenario, with a high-level Arc yourself, investing in a P1 spot on another high-level Arc is highly profitable, yielding a significant FP gain.
Example 2: New Player in a Mid-Level Arc
- Inputs:
- Target Arc Level: 80
- Your Arc Bonus: 0% (no Arc or low level)
- Target Spot: P3
Calculation & Results:
At Level 80, the Target Arc has a bonus multiplier of 1.9. The base FP reward for P3 at this level is 50 FPs.
- Actual FP Reward from Arc: 50 FPs * 1.9 = 95 FPs
- Recommended Contribution (1.9 thread): Ceiling(95 / 1.9) = 50 FPs
- Your Self-Bonus on Contribution: 50 FPs * (0 / 100) = 0 FPs
- Total FPs Received: 95 FPs + 0 FPs = 95 FPs
- Net FP Profit: 95 FPs - 50 FPs = 45 FPs (Profit!)
- Other Rewards: 0 BPs, 500 Medals, 25 Goods
Even without your own Arc, investing in lower spots like P3 on a common L80 Arc can still be profitable, though the FP gain is smaller. This is a great way for newer players to accumulate FPs and other rewards.
D) How to Use This Arc Calculator FoE
Using our Arc Calculator FoE is straightforward and designed for efficiency:
- Enter Target Arc Level: Input the current level of the Arc you are planning to contribute to. Ensure this is accurate, as it significantly impacts rewards.
- Enter Your Arc Bonus (%): Provide the bonus percentage your *own* Arc provides. For example, an Arc at level 80 gives a 90% bonus, so you would enter "90". If you don't have an Arc or it's very low level, you can enter "0".
- Select Target Spot: Choose the position you intend to take (P1, P2, P3, P4, or P5).
- Click "Calculate Arc Profit": The calculator will instantly process your inputs and display a detailed summary of your potential investment.
- Interpret Results:
- The large Net FP Profit shows your overall gain or loss in FPs.
- Recommended Contribution is the FPs you should spend for the spot in a 1.9 thread.
- Actual FP Reward from Arc is what the Arc provides directly.
- Your Self-Bonus on Contribution is the FPs you get back from your own Arc.
- The calculator also displays Blueprints, Medals, and Goods for the chosen spot.
- Copy Results: Use the "Copy Results" button to easily copy all calculated values to your clipboard, useful for sharing in guild chat or tracking your investments.
- Reset: The "Reset" button clears all fields and sets them back to their intelligent default values.
E) Key Factors That Affect Arc Calculator FoE Outcomes
Understanding the variables that influence the Arc Calculator FoE results is crucial for maximizing your profits and optimizing your gameplay:
- Target Arc Level: This is the most significant factor. Higher-level Arcs offer substantially larger base FP rewards and higher bonus multipliers. A level 80 Arc (1.9x bonus) is a common milestone, but Arcs at level 100, 120, or even 180+ offer dramatically increased returns.
- Your Own Arc Level/Bonus: The higher your own Arc's level, the greater the percentage of FPs you get back on *any* FPs you spend. This "self-bonus" directly reduces your net cost and increases your overall profit, making higher-level Arcs even more lucrative for you.
- Target Spot (P1-P5): The first place (P1) always yields the highest base FP, Blueprint, Medal, and Goods rewards, followed by P2, and so on. While P1 offers the most profit, lower spots can still be profitable, especially for players with lower Arc levels or those looking for specific BPs.
- Community Profit Factor: While our calculator defaults to the common "1.9 thread" factor, some guilds or players might use slightly different profit margins (e.g., 1.92, 1.85). This factor directly influences the recommended contribution for each spot.
- Blueprint Needs: Sometimes, the value of a spot isn't just about FPs. If you desperately need specific Blueprints for your own Great Buildings, taking a lower-profit spot that grants the needed BP might be worth it.
- Event and Quest Requirements: Certain in-game events or quests might require you to spend a specific amount of FPs or collect certain rewards. Using the Arc Calculator FoE can help you plan your contributions to fulfill these requirements efficiently while still aiming for profit.
F) Frequently Asked Questions about Arc Calculator FoE
Q: What is a "1.9 thread" in Forge of Empires?
A: A "1.9 thread" is a common guild strategy where players contribute Forge Points (FPs) to each other's Great Buildings (GBs), specifically the Arc, with the understanding that the Arc owner aims to receive 1.9 times their investment back from the investors. This ensures a 90% profit for the owner and provides a clear, fair system for contributions, often making it profitable for investors as well, especially if they have their own Arc.
Q: How does my own Arc's level affect the calculation?
A: Your own Arc's level determines your "self-bonus." When you spend FPs on any Great Building (including your own Arc or others'), your Arc returns a percentage of those FPs to you. A higher Arc level means a higher percentage return, significantly boosting your net profit from investments calculated by the Arc Calculator FoE.
Q: Can I use this calculator for non-optimal contributions (e.g., sniping)?
A: Yes, you can. While the calculator provides "recommended contributions" based on a 1.9 thread, you can manually adjust your actual contribution in-game. The results section will still show your potential net profit based on the Arc's level and your bonus, allowing you to assess if a "sniped" spot is still profitable for you. For more advanced strategies, consider an FoE Sniping Tool.
Q: Why are the numbers slightly different from other Arc calculators?
A: Minor discrepancies can arise from several factors:
- Rounding: Different calculators might round FP contributions or bonuses at different stages. Our calculator rounds up contributions to ensure the owner's profit.
- Data Source: The exact base FP rewards for various Arc levels can sometimes vary slightly between community data sources.
- Profit Factor: While 1.9 is standard, some communities use 1.92 or other factors.
Q: What are Blueprints (BPs), Medals, and Goods?
A: These are additional rewards you receive when securing a spot on a Great Building:
- Blueprints (BPs): Essential for leveling up your own Great Buildings.
- Medals: Used to purchase expansions in your city and participate in certain events.
- Goods: Resources like iron, cloth, or advanced goods, used for trading, guild treasury, research, and quests.
Q: What is the maximum Arc level?
A: Theoretically, the Arc has no hard maximum level. Players continuously level it up, with some reaching levels well over 200, 300, or even higher, requiring immense Forge Point investments and providing astronomical returns.
Q: Is it always profitable to invest in Arcs?
A: In a well-managed 1.9 thread, and especially if you have your own high-level Arc, investing in other Arcs is almost always profitable in terms of net FPs, BPs, Medals, and Goods. It's one of the most efficient ways to grow in FoE. However, if you contribute outside of a thread or to very low-level Arcs without your own bonus, your net FP profit might be lower or even negative.
Q: How often do Arc rewards or mechanics change?
A: Great Building mechanics, especially for core buildings like the Arc, rarely change. InnoGames (the developer) occasionally balances things, but major overhauls to the Arc's reward structure are uncommon. Our Arc Calculator FoE is updated to reflect any such changes if they occur.
