Forge of Empires 1.9 Calculator

What is the Forge of Empires 1.9 Calculator?

The Forge of Empires 1.9 Calculator is a specialized tool designed for players of the popular strategy game, Forge of Empires (FoE). It helps Great Building (GB) owners and contributors optimize their Forge Point (FP) investments and returns, primarily within the context of "1.9 threads" or "1.9 groups."

At its core, the "1.9" refers to a common agreement among players where contributors pay 1.9 times the base FP reward for a spot on a Great Building. This ratio is specifically tied to the Arc Great Building, which, at level 80, provides a 90% bonus to collected FPs, effectively making the "break-even" point for a contributor 1.9x the reward (1 FP reward + 0.9 FP bonus = 1.9 FP total return). This calculator simplifies the complex calculations involved in managing these contributions.

Who should use it? Any Forge of Empires player who owns Great Buildings and wants to level them efficiently, or any player who actively participates in 1.9 contribution groups. It's particularly useful for those looking to:

• Determine their own FP contribution to secure top spots (1st, 2nd, 3rd, etc.) on their GBs without overpaying.
• Calculate the remaining FPs that need to be filled by other players in a 1.9 thread.
• Understand the net profit or loss from securing specific spots on their own GBs.

Common misunderstandings: Many players confuse the "1.9" with a fixed, universal rule. While it's a common standard, it's tied directly to the Arc's bonus. A player with an Arc below level 80 will have a lower multiplier, and those with an Arc above level 80 will have a higher one (e.g., 1.92, 1.95, 2.0+). This calculator allows you to adjust the multiplier to match your specific Arc level, ensuring accurate results.

Forge of Empires 1.9 Calculator Formula and Explanation

The primary purpose of this forge of empires 1.9 calculator is to determine the owner's contribution for specific Great Building spots and the remaining FPs needed from the public, based on a given Arc bonus multiplier. The core formula revolves around calculating the cost to "lock" a spot for yourself at a profitable rate.

The Core Formula:

Owner's Contribution for Spot = Base FPs Reward for Spot × Your Arc Bonus Multiplier

This formula calculates the amount of Forge Points an owner needs to put into their own Great Building to secure a specific spot (e.g., 1st place) such that if another player were to take that spot, they would pay this amount according to the 1.9 rule. By paying this amount themselves, the owner effectively "buys" the spot from the perspective of the 1.9 thread dynamics, making it safe for others to fill the remaining FPs.

The calculator then sums these individual spot contributions to find the Total Owner Contribution and subtracts this from the Total FPs Needed for GB Level to determine the FPs Remaining for Public.

Practical Examples for Forge of Empires 1.9 Calculator

Let's illustrate how the forge of empires 1.9 calculator works with a couple of real-world scenarios from the game.

Example 1: Standard 1.9 Contribution

You are leveling your Observatory to level 10. It requires 2000 FPs for the next level. The base rewards for the top 5 spots are: 1st (100 FPs), 2nd (50 FPs), 3rd (20 FPs), 4th (10 FPs), 5th (5 FPs). Your Arc is at level 80, giving you a 1.9 Arc Bonus Multiplier.

• Inputs:
  • Total FPs Needed: 2000 FPs
  • Arc Multiplier: 1.9
  • Reward 1st: 100 FPs, Reward 2nd: 50 FPs, Reward 3rd: 20 FPs, Reward 4th: 10 FPs, Reward 5th: 5 FPs
• Calculation:
  • Owner Contrib. 1st = 100 FPs × 1.9 = 190 FPs (Net Loss: 90 FPs)
  • Owner Contrib. 2nd = 50 FPs × 1.9 = 95 FPs (Net Loss: 45 FPs)
  • Owner Contrib. 3rd = 20 FPs × 1.9 = 38 FPs (Net Loss: 18 FPs)
  • Owner Contrib. 4th = 10 FPs × 1.9 = 19 FPs (Net Loss: 9 FPs)
  • Owner Contrib. 5th = 5 FPs × 1.9 = 9.5 FPs (Net Loss: 4.5 FPs)
  • Total Owner Contribution (Top 5): 190 + 95 + 38 + 19 + 9.5 = 351.5 FPs
  • FPs Remaining for Public: 2000 FPs - 351.5 FPs = 1648.5 FPs
• Results: You need to contribute 351.5 FPs to secure the top 5 spots for yourself according to the 1.9 rule, leaving 1648.5 FPs for other players to contribute. Your total net loss for securing these spots is 167 FPs (90+45+18+9+4.5).

Example 2: Higher Arc Multiplier and Fewer Spots

You are leveling your Cape Canaveral to level 60, requiring 5000 FPs. The rewards are: 1st (200 FPs), 2nd (100 FPs), 3rd (50 FPs), 4th (25 FPs), 5th (15 FPs). Your Arc is at level 100, giving a 1.94 Arc Bonus Multiplier (you can input this exact value).

• Inputs:
  • Total FPs Needed: 5000 FPs
  • Arc Multiplier: 1.94
  • Reward 1st: 200 FPs, Reward 2nd: 100 FPs, Reward 3rd: 50 FPs, Reward 4th: 25 FPs, Reward 5th: 15 FPs
• Calculation:
  • Owner Contrib. 1st = 200 FPs × 1.94 = 388 FPs (Net Loss: 188 FPs)
  • Owner Contrib. 2nd = 100 FPs × 1.94 = 194 FPs (Net Loss: 94 FPs)
  • Owner Contrib. 3rd = 50 FPs × 1.94 = 97 FPs (Net Loss: 47 FPs)
  • Owner Contrib. 4th = 25 FPs × 1.94 = 48.5 FPs (Net Loss: 23.5 FPs)
  • Owner Contrib. 5th = 15 FPs × 1.94 = 29.1 FPs (Net Loss: 14.1 FPs)
  • Total Owner Contribution (Top 5): 388 + 194 + 97 + 48.5 + 29.1 = 756.6 FPs
  • FPs Remaining for Public: 5000 FPs - 756.6 FPs = 4243.4 FPs
• Results: With a higher Arc, your individual spot contributions are higher, leading to a larger total owner contribution of 756.6 FPs to secure the top 5 spots. This leaves 4243.4 FPs for your guildmates or friends in the 1.9 thread. Your total net loss for securing these spots is 366.6 FPs.

How to Use This Forge of Empires 1.9 Calculator

Using this forge of empires 1.9 calculator is straightforward and designed to provide quick, accurate insights into your Great Building leveling strategy.

1. Enter Total FPs Needed for Next GB Level: Find this number in your game by clicking on your Great Building and viewing its current level information. It's the total amount of FPs required to reach the next level.
2. Input Your Arc Bonus Multiplier: This is crucial. If your Arc is level 80, use 1.9. If it's higher (e.g., 90, 100, 180), consult a FoE wiki or an Arc bonus table to find your exact multiplier (e.g., 1.92, 1.94, 2.08). Enter this decimal value.
3. Enter FPs Rewards for Each Spot: For each of the top 5 spots, input the base Forge Point reward your Great Building offers. You can find these rewards listed in your GB's contribution window in-game. These values are specific to the GB type and its current level. If a spot doesn't exist (e.g., only 3 spots available), enter 0 for the non-existent spots.
4. Review Results: The calculator updates in real-time.
   • FPs Remaining for Public: This is the primary result, showing how many FPs other players need to contribute to fully level your GB after you've secured the top 5 spots.
   • Total Owner Contribution: The sum of FPs you (the owner) would contribute to secure the top 5 spots at your specified Arc multiplier.
   • Total Owner Net Profit/Loss: The overall profit or loss you incur by taking these spots yourself, compared to their base FP rewards.
   • The detailed table breaks down contributions and net profit/loss for each individual spot.
5. Interpret the Chart: The bar chart provides a visual representation of how the total FPs required are split between your contribution for the top 5 spots and the FPs left for the public.

Remember that the "1.9 rule" is a community convention. While this calculator helps you adhere to it, always communicate with your guild or contributing players about expectations.

Key Factors That Affect Forge of Empires 1.9 Calculations

Understanding the factors that influence the forge of empires 1.9 calculator's output is crucial for effective GB management and strategy.

1. Your Arc Great Building Level: This is the most significant factor. The higher your Arc's level, the higher your bonus multiplier. For instance, an Arc at level 80 gives a 1.9 multiplier, but an Arc at level 180 can give over a 2.0 multiplier. A higher multiplier means you contribute more FPs to secure a spot for yourself (or others contribute more to take a spot from you) but also means higher FP returns on spots you take on others' GBs.
2. Total FPs Needed for the GB Level: The overall cost of the GB level directly impacts the "FPs Remaining for Public." Higher-level GBs often require thousands of FPs, making the 1.9 calculation essential for managing large sums.
3. Base FPs Rewards for Each Spot: Different Great Buildings and different levels of the same GB offer varying FP rewards for 1st, 2nd, 3rd, 4th, and 5th spots. Accurately inputting these values is vital for precise calculations. A GB with higher base rewards will require a larger owner contribution (at the specified Arc multiplier) to secure those spots.
4. Number of Spots the Owner Secures: This calculator assumes the owner secures the top 5 spots. However, in practice, an owner might only secure the 1st and 2nd spots, leaving more FPs for the public to fill. Adjusting your strategy will change the total owner contribution and public FPs.
5. Community & Guild Rules: While the 1.9 is a common standard, some guilds might use slightly different multipliers (e.g., 1.85 or 1.92) or have specific rules about how many spots the owner should fill. Always conform to your guild's practices.
6. Other GB Rewards: While this calculator focuses on FPs, GB spots also grant blueprints, medals, goods, and other resources. These non-FP rewards influence the overall value of a spot but are not directly factored into the FP contribution calculation.
