What is 1.9 calculator foe?
The 1.9 calculator foe is a specialized utility used by players of the popular strategy game Forge of Empires. It allows players to determine exactly how many Forge Points (FP) are required to secure a position in a Great Building (GB) and how much an investor with a Level 80 Arc should contribute. In modern FoE gameplay, the “1.9 Thread” has become the gold standard for efficient leveling.
Who should use it? Any player looking to level their Great Buildings without losing Forge Points or any player looking to help guildmates while breaking even. A common misconception is that the 1.9 calculator foe is only for high-level players; in reality, even new players benefit significantly by using these mathematical ratios to avoid being “sniped” by predatory neighbors.
1.9 calculator foe Formula and Mathematical Explanation
The math behind the 1.9 calculator foe is straightforward but critical for precision. The contribution is calculated by multiplying the base reward of a position by 1.9. To “secure” or “lock” a position, the owner must invest enough FP so that no other player can contribute more than the 1.9 amount and take the spot.
The derivation for securing a spot is: Owner Investment = Total Level Cost - (2 × 1.9 × Base Reward). If other players have already invested, their contributions are subtracted from the result.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total Cost | Total FPs for the GB level | FP | 50 – 50,000+ |
| Base Reward | Reward for P1-P5 | FP | 5 – 5,000+ |
| 1.9 Factor | The standard Arc multiplier | Multiplier | 1.9 (Fixed) |
| Securing Amount | Amount owner must pay to lock | FP | 0 – Total Cost |
Practical Examples (Real-World Use Cases)
Example 1: Leveling The Arc
Suppose you are leveling your Arc to Level 30. The total cost is 1,200 FP. The P1 base reward is 200 FP. Using the 1.9 calculator foe, the investor contribution is 200 × 1.9 = 380 FP. To secure P1, you need to calculate: 1,200 - (380 × 2) = 440 FP. Once you put in 440 FP, P1 is safe to be taken in a 1.9 thread.
Example 2: Low-Level Zeus
For a Statue of Zeus, the total level cost is 100 FP. P1 base reward is 10 FP. 1.9 contribution is 19 FP. The owner needs 100 - (19 × 2) = 62 FP to secure. This ensures that even if a neighbor puts in 20 FP, they cannot overtake the person contributing 19 FP because the remaining FP are insufficient to bypass the 1.9 investor.
How to Use This 1.9 calculator foe Calculator
- Step 1: Enter the ‘Total FP Cost’ for the current level of your Great Building.
- Step 2: Look at the Reward list for your building and enter the ‘Base Reward’ for the position you want to fill (P1, P2, etc.).
- Step 3: Input any existing Forge Points you have already added and any points added by other players.
- Step 4: The 1.9 calculator foe instantly shows the ‘Contribution Amount’. This is what your donor should pay.
- Step 5: Check the ‘Amount to Secure’. If this number is positive, you must add that many Forge Points before posting in a 1.9 thread.
Key Factors That Affect 1.9 calculator foe Results
Several factors influence the outcome and safety of your Great Building investments:
- Arc Bonus Level: While 1.9 is standard, players with Arcs above Level 80 might offer 1.92 or 1.94, changing the 1.9 calculator foe math.
- Sniping Risk: Neighbors can often see when a building is “primed.” Using the 1.9 calculator foe ensures they cannot profitably steal a spot.
- Neighbor Investments: If a neighbor has already put in points, it reduces the amount the owner needs to invest to secure.
- GB Level Range: In the “Sweet Spot” (usually level 30-60), base rewards are so high that buildings often secure themselves with zero owner investment.
- Guild Thread Speed: High-speed guilds require you to use the 1.9 calculator foe accurately to prevent building stalls.
- Reward Rounding: FoE always rounds rewards down. The 1.9 calculator foe should account for these decimal differences to ensure exact contribution totals.
Frequently Asked Questions (FAQ)
Q: What does 1.9 mean in Forge of Empires?
A: It refers to the 90% bonus a level 80 Arc provides. 1.0 (base) + 0.9 (bonus) = 1.9 multiplier.
Q: Is 1.9 calculator foe better than a swap thread?
A: Yes, 1.9 threads are mathematically superior for leveling efficiency and protecting your investment from snipers.
Q: Can I use 1.9 for any Great Building?
A: Absolutely. Any GB that offers Forge Point rewards as a placement prize can be managed using the 1.9 calculator foe.
Q: What happens if I don’t secure the building?
A: A “sniper” could put in fewer Forge Points than the 1.9 amount but enough to ensure no one else can overtake them, causing you to lose FP efficiency.
Q: Does the 1.9 calculator foe handle rounding?
A: Yes, standard practice is to round up for contributions to ensure the owner doesn’t lose out, or follow the game’s floor rounding for rewards.
Q: Why do some players ask for 1.92?
A: Players with Arcs level 100+ have a higher bonus and may offer a “profit” to the owner by paying 1.92x instead of 1.9x.
Q: How do I find my building’s base reward?
A: Open your Great Building, click the “i” or reward chest icon, and look at the reward for positions 1 through 5 without your own Arc bonus applied.
Q: Is the 1.9 calculator foe allowed by the game rules?
A: Yes, it is simply a mathematical tool to help with manual planning. It does not automate the game.
