What is a Foe Great Buildings Calculator?
A foe great buildings calculator is an essential tool for players of the popular strategy game, Forge of Empires. Its primary purpose is to calculate the number of Forge Points (FPs) a player (the owner) must contribute to level up their Great Building (GB) after accounting for contributions from other players. These other players, often called “snipers” or patrons, donate FPs to secure a reward spot (e.g., 1st, 2nd, 3rd place).
This calculator is used by everyone from new players learning the system to seasoned veterans optimizing their Forge Point strategy. A common misunderstanding is that these calculators only show the total cost; in reality, their main strength is breaking down the cost-sharing dynamic, particularly within the context of “1.9 threads” or other established contribution rates. Understanding this is key to efficient leveling and using a good foe 1.9 calculator is a game changer.
Foe Great Buildings Calculator Formula and Explanation
The core calculation is not a single complex formula, but a process of subtraction based on known values. The fundamental principle is:
Owner's Cost = Total FP Cost for Level - Sum of all Patron Contributions
Where the Patron Contribution for each spot is determined by:
Patron Contribution = Reward FPs for Spot * Patron Rate
The “Patron Rate” is the key variable, most commonly 1.9, which represents the 90% bonus FPs a player with a level 80 Arc receives when contributing to another GB. Our foe great buildings calculator automates this entire process for you.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total FP Cost | The total Forge Points required to complete a single level. | Forge Points (FPs) | 30 – 70,000+ |
| Patron Rate | The multiplier used to calculate a patron’s donation. | Ratio (Unitless) | 1.8 – 1.95 |
| Reward FPs | The base number of FPs awarded for securing a top 5 position. | Forge Points (FPs) | 5 – 10,000+ |
| Owner’s Cost | The net FPs the building’s owner must contribute. | Forge Points (FPs) | Negative to Positive |
Practical Examples
Example 1: Leveling a High-Level Arc
A very common scenario is leveling The Arc to 80 to get the 90% rewards bonus. Let’s calculate the final push from level 79 to 80.
- Inputs: Great Building: The Arc, Current Level: 79, Target Level: 80, Patron Rate: 1.9
- Calculation: The total cost is 5,163 FPs. The top 5 reward spots are filled by patrons contributing at the 1.9 rate.
- Results: The calculator shows the owner’s cost is only a fraction of the total, as patrons cover the majority to get the huge FP rewards from the Arc. This highlights why a arc calculator foe is so popular.
Example 2: Leveling a Low-Level Attack Building
A player wants to level their Statue of Zeus from level 6 to 7.
- Inputs: Great Building: Statue of Zeus, Current Level: 6, Target Level: 7, Patron Rate: 1.9
- Calculation: The total FP cost is 260. The rewards are much smaller, so patron contributions are lower.
- Results: The owner will have to pay a significantly larger percentage of the total cost compared to the Arc example. The foe great buildings calculator shows the exact amount needed to “secure” each spot for patrons.
How to Use This Foe Great Buildings Calculator
Using our tool is straightforward and designed for quick insights. Follow these steps for an accurate foe gb cost analysis:
- Select Great Building: Choose your GB from the dropdown list. The data for costs and rewards is pre-loaded.
- Enter Current & Target Levels: Input the starting level and the level you wish to achieve. The calculator can handle multi-level calculations.
- Set the Patron Rate: Enter the contribution rate used by your guild or friends. 1.9 is standard, but 1.8, 1.85, and 1.92 are also common.
- Analyze the Results: The “Total Owner’s Cost” is your primary result. The table below shows the required FPs for each reward spot at the target level and how many FPs the owner must add to make that spot “secure” for a patron.
- Interpret the Chart: The bar chart provides a simple visual of how the total cost is divided between you (the owner) and your patrons.
Key Factors That Affect Great Building Leveling
Several factors influence the cost and strategy of your great building leveling journey.
- The Arc Bonus: This is the single most important factor. Owning a high-level Arc dramatically reduces the net cost of leveling other GBs, as the rewards you gain from sniping exceed your contributions. See our guide on The Arc for more.
- Patronage Rate: The rate (1.9, 1.85, etc.) directly impacts your cost. A higher rate means patrons pay more, and you pay less.
- FP Inventory: Having a large bank of Forge Points allows you to quickly secure spots on your own buildings or take profitable spots on others.
- Guild Membership: A good guild provides access to dedicated 1.9 threads, ensuring you always have patrons available to help level your buildings cheaply.
- Building Priority: The order in which you level buildings matters. Leveling an Arc first is almost always the recommended strategy before focusing on attack or goods buildings. Our list of top 5 Great Buildings can help.
- FP Daily Production: Your ability to generate FPs daily from town hall, event buildings, and other GBs determines the pace at which you can level.
Frequently Asked Questions (FAQ)
A “1.9 Thread” is a dedicated chat or forum thread where players agree to contribute to each other’s Great Buildings at a rate of 1.9 times the spot’s reward. It’s a system built on trust and the mutual benefit provided by high-level Arcs.
A spot is “secure” when the remaining FPs needed to level the building are less than the reward for the next available spot. Our calculator shows a “To Secure” value, which is the amount of FPs the owner must add (after the higher spots are taken) to lock in a specific position for a patron.
A negative cost (a profit) occurs when the sum of patron contributions exceeds the total FP cost of the level. This is common on lower-cost GBs when a high-level Arc owner takes a spot, as their 1.9 contribution is very high.
The consensus strategy is to focus on The Arc first. Get it to level 80. After that, focus on attack-boosting buildings like Zeus, Cathedral of Aachen, and Castel del Monte. Check our full GB list for ideas.
While 1.9 is the standard, there is no single “best” rate. It depends on your guild and your goals. The important part is that everyone in your group agrees on the same rate for fairness.
It calculates the owner cost and patron contributions for each level individually and then sums them up to give you a total cost for the entire range. The detailed table, however, only shows the breakdown for the final target level.
This is the number of Forge Points the owner must contribute to guarantee a spot for a patron. For P1 (1st place), it’s the amount needed to lock out any potential “snipers” from taking P1 from your intended patron. For P2, it assumes P1 is already taken and shows the amount needed to secure P2.
It prevents costly mistakes. Accidentally leaving a spot “un-secured” means a player outside your contribution group can “snipe” the spot for cheaper, disrupting your plans and potentially costing you or your patrons FPs.
