A Deep Dive into the Foe Great Buildings Calculator
This article provides a comprehensive guide to using a foe great buildings calculator, understanding the underlying mechanics, and optimizing your Forge of Empires strategy for rapid Great Building leveling.
What is a Foe Great Buildings Calculator?
A foe great buildings calculator is an essential tool for any serious Forge of Empires player. It’s designed to compute the exact number of Forge Points (FPs) a Great Building (GB) owner must contribute to level up their building when utilizing player-driven contribution systems, famously known as “1.9 threads”. These threads, named after the 90% bonus a level 80 Arc provides, allow players to help each other level GBs efficiently. The calculator removes the complex manual math, prevents costly errors, and ensures both the owner and contributors get a fair deal. Anyone regularly leveling Great Buildings, especially beyond level 10, will find a foe great buildings calculator indispensable for managing their forge points. A common misconception is that these tools are only for high-level players, but even players with lower-level Arcs using different rate threads (like 1.85 or 1.8) can benefit immensely.
Foe Great Buildings Calculator Formula and Mathematical Explanation
The core logic of a foe great buildings calculator revolves around a simple principle: the owner covers the portion of the leveling cost not paid for by patrons. Here’s the step-by-step math:
- Calculate Patron Cost: For each reward position (P1 to P5), the cost for a patron to “buy” that spot is determined. Formula: `Patron Cost = Reward FP * Contribution Rate`. For a standard 1.9 thread, the rate is 1.9.
- Sum Patron Contributions: The costs for all five positions are added together to get the total FPs provided by contributors. Formula: `Total Patron Contribution = Sum of all Patron Costs`.
- Calculate Owner’s Share: The final step is to subtract the total patron contribution from the total FP cost of the level. Formula: `Owner’s Cost = Total FP Cost for Level – Total Patron Contribution`.
This calculation ensures that every single Forge Point is accounted for. Using a foe great buildings calculator automates this process, saving time and preventing miscalculations that could lead to lost FPs or sniped positions.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total FP Cost | The total Forge Points required to complete the current GB level. | Forge Points | 50 – 10,000+ |
| Contribution Rate | The multiplier applied to rewards (e.g., from an Arc bonus). | Multiplier | 1.8 – 1.95+ |
| PX Reward | The Forge Point reward for securing position ‘X’ (1-5). | Forge Points | 0 – 5,000+ |
| Owner’s Cost | The net Forge Points the GB owner must personally invest. | Forge Points | Varies Greatly |
Practical Examples (Real-World Use Cases)
Let’s see the foe great buildings calculator in action with two common scenarios.
Example 1: Leveling an Arc from 80 to 81
An Arc going to level 81 has a high cost and massive rewards, making a foe great buildings calculator crucial.
- Inputs:
- Total FP Cost: 1,725 FP
- P1 Reward: 845 FP, P2: 280 FP, P3: 90 FP, P4: 30 FP, P5: 10 FP
- Contribution Rate: 1.9
- Outputs (from Calculator):
- P1 Patron Cost: 845 * 1.9 = 1606 FP
- P2 Patron Cost: 280 * 1.9 = 532 FP (Note: this is more than the remaining cost after P1 is taken, so it’s not a real scenario. The calculator handles this.)
- Total Patron Contribution (correctly calculated): ~1656 FP
- Owner’s Final Cost: 1725 – 1656 = 69 FP
- Interpretation: By selling all spots in a 1.9 thread, the owner only needs to pay 69 FPs to complete a very expensive level. The foe great buildings calculator shows this incredible efficiency.
Example 2: Leveling a Château Frontenac (Low Level)
Even at lower levels, a foe great buildings calculator helps.
- Inputs:
- Total FP Cost: 260 FP
- P1 Reward: 45 FP, P2: 15 FP, P3: 5 FP, P4: 0 FP, P5: 0 FP
- Contribution Rate: 1.9
- Outputs (from Calculator):
- Total Patron Contribution: (45*1.9) + (15*1.9) + (5*1.9) = 85.5 + 28.5 + 9.5 = 123.5 (rounded to 124 FP)
- Owner’s Final Cost: 260 – 124 = 136 FP
- Interpretation: The owner effectively gets the level for about half price. The foe great buildings calculator instantly provides the numbers needed to post in a thread.
How to Use This Foe Great Buildings Calculator

Key Factors That Affect Foe Great Buildings Calculator Results
Several factors can influence the outcomes from a foe great buildings calculator and your overall leveling strategy.
- The Arc Bonus: This is the single most significant factor. A higher Arc bonus means a higher contribution rate (e.g., 1.9+), drastically reducing the owner’s share of the cost. Leveling your Arc is the best investment for long-term growth. See our guide to the Arc bonus.
- GB Level: As a GB’s level increases, the ratio of reward FPs to total cost changes. Some levels are more “profitable” to level via contribution threads than others. Our foe great buildings calculator helps identify these sweet spots.
- Sniping: A “sniper” is a player outside your group who contributes to your GB for a profit, disrupting your plans. The calculator’s “Secure Cost” feature is vital for preventing this by showing how many FPs you must add to make sniping unprofitable for others. Check our sniping calculator.
- Guild vs. Public Threads: Guild threads are generally safer and more reliable. Public threads can be faster but carry a higher risk of sniping or non-payment.
- FP Inventory: Having a healthy stock of Forge Points allows you to “secure” your GB spots quickly, making them available for your contributors without delay. A tool like a goods calculator can help you trade for more FPs.
- Overall Strategy: Your choice of which GBs to level impacts your progress. Attack buildings, FP-producing buildings, and special buildings like the Château or Blue Galaxy all have different priorities. A foe great buildings calculator is a tactical tool within your broader strategic plan.
Frequently Asked Questions (FAQ)
1. Why is the Owner’s Cost sometimes negative?
A negative cost (profit) can occur on very high-level GBs where the rewards, when multiplied by a high Arc rate, exceed the total cost of the level. This is rare but is a primary goal for advanced players. A foe great buildings calculator will accurately show this profit.
2. What does “securing a spot” mean?
Securing a spot means adding enough of your own FPs so that it’s impossible for another player to contribute and take the spot from your intended contributor for a profit. Our foe great buildings calculator determines this critical value for you.
3. Can I use this calculator for rates other than 1.9?
Absolutely. The “Contribution Rate” field is fully customizable. Whether your group uses 1.8, 1.85, 1.92, or any other rate, the foe great buildings calculator will provide the correct numbers.
4. What if a position offers zero FP reward?
If a reward is 0, the patron cost will also be 0. This spot cannot be “sold” in a contribution thread, and the owner is responsible for covering those FPs. The calculator handles this automatically.
5. How do I find the total FP cost and rewards?
Click on your Great Building in your city, and go to the “Levels” tab. It will show the total FP cost for the next level and the rewards for the top 5 contributors once the level is complete.
6. Is a higher-level Arc always better?
Yes. A higher Arc directly increases the profitability of contributing to others’ GBs and reduces your costs when leveling your own via a foe great buildings calculator. There is no downside to a higher Arc, besides the leveling cost itself. See this GvG strategy guide to see how a strong Arc helps.
7. Why does the chart show ‘Patrons’ as one group?
The chart simplifies the visualization by aggregating all contributions from P1 to P5 into a single “Patrons” bar. This provides a clear, at-a-glance view of the cost split between you (the owner) and everyone else helping you.
8. What’s the best strategy if I can’t afford the secure cost?
If you can’t afford to secure a spot, you can try to “fast-level” it by asking multiple contributors to add FPs simultaneously. However, this is risky. The safest method is to wait until you have enough FPs, a process made easier by planning with a foe great buildings calculator.
