Forge of Empires Great Building Calculator & 1.9 Thread Planner

Welcome, fellow strategists of Forge of Empires! Whether you're a seasoned veteran or just starting your journey through the ages, managing your Great Buildings (GBs) is paramount to your city's success. This interactive calculator is designed to help you efficiently plan your GB leveling, especially when participating in or hosting a 1.9 thread.

Understanding Great Buildings in Forge of Empires

Great Buildings (GBs) are the cornerstone of any thriving city in Forge of Empires. These monumental structures provide significant bonuses, resources, and boosts that are crucial for progression, military strength, and economic prosperity. From generating Forge Points (FPs) and goods to boosting attack and defense, GBs are indispensable assets.

Why Use a GB Calculator?

While the concept of leveling a GB is straightforward – contribute FPs until it reaches the next level – optimizing this process can be complex. A GB calculator, particularly one focused on the "1.9 thread," offers several key benefits:

• Efficient FP Spending: Plan exactly how many FPs you need to contribute to your own GB or to secure a profitable spot on another player's GB.
• Maximize Returns: For contributors, identify the most profitable spots to invest your FPs, ensuring you get the highest possible return.
• Streamline 1.9 Threads: As a GB owner, easily determine the exact contributions needed from others to fill your GB, minimizing your own cost and ensuring smooth guild participation.
• Prevent Sniping: By knowing the precise lock-in amounts, you can protect your GB spots from "snipers" who might try to take a spot for less than the agreed-upon 1.9 rate.
• Strategic Planning: Helps in long-term planning for your GB progression and resource management.

The 1.9 Thread Explained

The "1.9 thread" is a fundamental cooperation mechanism in Forge of Empires guilds, primarily facilitated by players who own a high-level Arc Great Building (Level 80 or higher). An Arc at level 80 provides a 90% bonus to blueprint and medal rewards from contributing to other players' GBs. This means for every Forge Point reward you receive, your Arc effectively doubles it (100% base + 90% bonus = 190% total, or 1.9 times the base reward).

In a 1.9 thread, a GB owner with a high-level Arc offers their GB spots to guildmates (or trusted friends) at a rate where the contributor puts in FPs equal to (Reward FPs / Owner's Arc Bonus). For an Arc 80 owner, this is Reward FPs / 1.9. This ensures the contributor makes a profit, and the owner efficiently fills their GB spots with minimal personal FP investment.

For example, if a P1 spot offers a 50 FP reward, and the owner has an Arc Lvl 80 (1.9 bonus):

• A contributor puts in ceil(50 / 1.9) = 27 FPs.
• The contributor receives 50 FPs back, making a profit of 50 - 27 = 23 FPs.
• The owner "pays" the difference for that spot, ensuring their GB gets filled.

This system creates a symbiotic relationship where both the GB owner and the contributors benefit, accelerating GB progression for everyone involved.

How to Use This Calculator

1. GB Name & Level: Enter the name of your Great Building and its current level for easy tracking.
2. Total FPs for THIS Level: Input the total Forge Points required to complete the current level you are working on (e.g., to go from Level 10 to 11).
3. FPs Currently on GB: Enter any FPs already contributed to the current level.
4. P1-P5 Reward FPs: Look up the specific FP rewards for 1st, 2nd, 3rd, 4th, and 5th place for your GB at its current level. These values are crucial for accurate calculations. You can find these on FoE wikis or in-game.
5. Your Arc Bonus: Enter your Arc's bonus multiplier. For an Arc at Level 80, this is 1.90. Adjust if your Arc is higher or lower.
6. Click "Calculate": The calculator will instantly show you the remaining FPs, the required 1.9 contributions for each spot, the profit for contributors, and your own remaining cost.

Tips for Effective GB Leveling & 1.9 Participation

• Join an Active Guild: A strong guild with established 1.9 threads is your best asset for rapid GB progression.
• Prioritize Your Arc: Leveling your Arc to at least 80 should be a top priority. It unlocks the full potential of 1.9 threads for both hosting and contributing.
• Know Your GBs: Understand which GBs provide the most benefit for your playstyle and age. Not all GBs are equally valuable at all stages.
• Collect FPs Religiously: Log in frequently to collect FPs from your Town Hall, GBs, and event buildings.
• Communicate: Always communicate in your guild's 1.9 thread. State which GB you are putting up, what level, and confirm spots before contributing.
• Use External Resources: FoE wikis and community sites often have detailed tables for GB FP costs and rewards per level.

Conclusion

The Forge of Empires Great Building Calculator is an indispensable tool for maximizing your efficiency and profitability in the game. By leveraging the power of the 1.9 thread and strategic planning, you can accelerate your city's growth, strengthen your military, and dominate the continent map. Happy forging!
