Foe Great Building Calculator

The Ultimate 1.9 Investment and Safe Spot Tool for Forge of Empires

What is foe great building calculator?

The foe great building calculator is a specialized tool designed for Forge of Empires players to optimize their Great Building (GB) leveling process. In the highly competitive world of FoE, the foe great building calculator serves as the primary method for calculating “1.9 thread” investments. This system relies on players having a level 80 Arc, which provides a 90% bonus to rewards gained from contributing to other players’ Great Buildings.

Who should use it? Every active player from Iron Age to Space Age Venus. Whether you are a “sniper” looking for profit or a guild member participating in 1.9 power-leveling groups, the foe great building calculator ensures you never overpay and your spots remain “safe” from external snipers. A common misconception is that you simply add the FP; however, the math behind “securing” a spot requires precise calculations of the remaining FP pool.

foe great building calculator Formula and Mathematical Explanation

The mathematical foundation of the foe great building calculator revolves around two main concepts: the Boosted Reward and the Safe Spot threshold. The core logic ensures that once a contributor puts in their points, no other player can overtake them, even if the owner adds no more points.

The Core Variables

Variable	Meaning	Unit	Typical Range
Total FP	Cost to complete level	Forge Points	100 – 150,000+
Arc Factor	Bonus multiplier (1 + %/100)	Multiplier	1.0 – 2.0+
Base Reward	Standard game reward for spot	Forge Points	5 – 5,000
Owner Investment	FP contributed by GB owner	Forge Points	Variable

The Step-by-Step Derivation

To determine how much an owner needs to invest to make P1 safe using the foe great building calculator logic:

1. Calculate Boosted Reward: Boosted = Base Reward * (1 + Arc Bonus)
2. Determine Remaining FP: Remaining = Total - Current Owner Investment
3. Safe Threshold: A spot is safe when Remaining - Boosted <= Boosted
4. Simplified Safe Formula: Owner Investment Needed = Total - (Boosted * 2)

Practical Examples (Real-World Use Cases)

Example 1: The Level 10 Arc
Suppose your Arc is moving from level 10 to 11. The total cost is 750 FP. The P1 base reward is 50 FP. Using the foe great building calculator with a 1.9 bonus, the boosted P1 is 95 FP. To make P1 safe, the owner must put in 750 - (95 * 2) = 560 FP. Once the owner has 560 FP in, P1 can take the spot for 95 FP, and no one can snipe them.

Example 2: High-Level Alcatraz
A level 60 Alcatraz requires 3,500 FP. P1 base is 600 FP (1,140 boosted). The owner uses the foe great building calculator and sees they need to invest 3,500 - (1,140 * 2) = 1,220 FP. This allows the owner to save over 2,200 FP by using contributors instead of self-leveling.

4. Input Base Rewards: These are found by clicking the rewards icon (chest) on the GB screen.
5. Analyze Results: The foe great building calculator will instantly show you how much more you need to pay for each spot (P1 through P5).
6. Copy Results: Use the "Copy" button to get a pre-formatted text string for your guild's 1.9 boost thread.

Key Factors That Affect foe great building calculator Results

• Arc Level: The higher your Arc, the lower your personal cost to level buildings, as you can take higher spots in others' GBs for profit.
• Building Type: High-reward buildings like the Arc or Castel del Monte reach "safe" points much faster than low-reward buildings.
• Sniping Risk: If you don't use a foe great building calculator, neighbors might put in just enough FP to take a top spot at a cost lower than the 1.9 rate, stealing your rewards.
• Guild Rules: Some guilds use 1.92 or 1.94 threads, which changes the Arc Factor used in the foe great building calculator.
• Self-Leveling: Putting in too many FP early is "wasteful" but safe; putting in too few makes you a target for snipers.
• Reward Rounding: FoE always rounds boosted rewards UP to the nearest whole number, a calculation our foe great building calculator handles automatically.

Frequently Asked Questions (FAQ)

Why does the 1.9 thread exist?

It is a symbiotic relationship where high-level players get medals and blueprints for free, while the GB owner gets their building leveled at a 1.9x discount compared to the base reward value.

What does "safe" mean in the foe great building calculator?

A spot is safe when the remaining FP required to finish the level is less than or equal to twice the contributor's reward. This prevents anyone else from outbidding them.

Can I use this calculator for 1.8 threads?

Yes, simply change the "Arc Bonus Percentage" field to 80 instead of 90.

Why is the total owner cost so high on low levels?

On lower levels, the rewards are small relative to the total cost, so the owner must bridge a larger gap. As the GB levels up, rewards scale faster than costs.

Does the foe great building calculator handle sniping?

Yes, by calculating the "Safe Spot," it specifically identifies the threshold where sniping becomes impossible.

What if someone puts in more than the 1.9 rate?

This is usually a donation or a mistake. The owner benefits, but in most guilds, you should only ask for the exact 1.9 amount.

Is the Arc 90% the maximum bonus?

No, level 80 provides 90%. Levels above 80 continue to increase the bonus (e.g., Level 180 provides 100% or 2.0x), but 1.9 is the standard community baseline.

How often should I use the foe great building calculator?

You should use it for every single level of every Great Building to maximize your FP efficiency.
