Forge Of Empire Calculator

Calculate the exact Forge Points (FP) needed to secure your Great Building spots using the 1.9 boost standard.

Position	Base Reward	1.9 Boosted	Owner Safe Spot

* Safe Spot Calculation: The total investment the owner must have for that specific position to be locked (un-snipeable).

What is a Forge of Empire Calculator?

A forge of empire calculator is a specialized utility designed for players of the strategy game Forge of Empires. Its primary purpose is to calculate “safe spots” for Great Building (GB) investments. In high-level play, guilds often operate “1.9 Boost Threads” where players with level 80 Arcs contribute to each other’s buildings for no profit, simply to help everyone grow faster.

Who should use it? Any player who owns a Great Building and wants to ensure they don’t get “sniped” (where an outsider takes a top reward spot for less than the 1.9 value). It is also vital for contributors to know exactly how much to pay. A common misconception is that the calculator only matters for the Arc; however, it is essential for every building from the Statue of Zeus to the Space Carrier.

Forge of Empire Calculator Formula and Mathematical Explanation

The math behind the forge of empire calculator relies on the interaction between the base reward, the multiplier, and the current progress. To calculate if a spot is “safe,” we use a formula to determine when the remaining Forge Points needed for a level are less than double what a contributor would pay.

Variable	Meaning	Unit	Typical Range
Total Level Cost	Total FP to level up	Forge Points (FP)	100 – 100,000+
Base Reward	Default FP reward for spot	Forge Points (FP)	5 – 5,000
Boost Factor	Arc multiplier used	Decimal	1.8 – 1.95
Safe Spot	Owner investment threshold	Forge Points (FP)	Calculated

The core logic: Owner Investment Needed = (Total Level Cost + Others Invested) – (2 * Boosted Reward). If the result is less than current owner investment, the spot is safe.

Practical Examples (Real-World Use Cases)

Example 1: The Arc Level 30
Suppose your Arc requires 1500 FP to level. P1 base reward is 200 FP. Using a 1.9 forge of empire calculator, P1 needs 380 FP (200 * 1.9). To make P1 safe, you need to add FP until: (1500 – (2 * 380)) = 740 FP. Once you put in 740, P1 is secure.

Example 2: Sniping Prevention
A neighbor has put 100 FP into their building. The level costs 1000. P1 reward is 100. If you use the forge of empire calculator, you see that if you put in 450 FP, you “lock” the spot because the remaining 450 is now impossible for anyone else to match while you hold the top rank.

How to Use This Forge of Empire Calculator

1. Input Total FP: Look at your Great Building and find the total amount required for the current level.
2. Enter Your Progress: Type in how many Forge Points you have already contributed.
3. Check Other Investments: If neighbors or guildmates have already added points, enter that total.
4. Set the Boost: Most guilds use 1.9. If your guild uses 1.8 or 1.85, adjust the factor accordingly.
5. Analyze Results: The forge of empire calculator will show you exactly how much more you need to add to secure each of the 5 reward positions.

Key Factors That Affect Forge of Empire Calculator Results

• Arc Level: Your own Arc level determines the rewards you get, but the calculator helps you determine what others with level 80+ Arcs should pay you.
• Great Building Type: Different buildings (e.g., Cape Canaveral vs. Oracle of Delphi) have vastly different reward scales.
• Level Range: The “Sweet Spot” (levels 30-60) usually requires the owner to pay very little, while early and late levels require high self-investment.
• Guild Rules: Some guilds mandate a 1.9 rate, while others might allow profit-taking or higher boosts like 1.92.
• Neighbor Sniping: If you don’t use a forge of empire calculator, neighbors can steal rewards, costing you hundreds of FP in the long run.
• Investment Speed: Calculating safe spots quickly allows you to post in threads before neighbors notice an open building.

Frequently Asked Questions (FAQ)

Why is it called a 1.9 calculator?

Because a Level 80 Arc provides a 90% bonus (1.9x) to all Great Building rewards. This has become the global standard for fair trade.

What does “Locking a spot” mean?

It means the owner has put enough FP in so that no matter what any other player does, the contributor’s spot cannot be overtaken.

Can I use this for 1.8 or 1.85 threads?

Yes, simply change the “Boost Factor” input in our forge of empire calculator to 1.8 or 1.85.

Does this calculator work for all Great Buildings?

Yes, the logic of Forge Points and rewards is consistent across every Great Building in Forge of Empires.

What if the “Safe Spot” result is negative?

It means the spot is already safe! You don’t need to add any more FP for that specific position to be secure.

Is sniping illegal in the game?

No, it is a game mechanic. However, using a forge of empire calculator helps you protect yourself from it.

Why do some levels cost more for the owner?

In the early levels (1-20) and very high levels (80+), the base rewards are small compared to the total cost, requiring more “self-invest.”

How often should I use the calculator?

Every time you are about to level up a building or post in a guild 1.9 thread.
