What is a FoE 1.9 Calculator?

The FoE 1.9 calculator is an essential tool for players of Forge of Empires who participate in "1.9 threads" or "1.9 groups." This system is a community-driven strategy designed to efficiently level up Great Buildings (GBs) while ensuring fair rewards for contributors. In essence, it helps players determine the precise amount of Forge Points (FPs) they need to contribute to secure a specific reward spot (1st, 2nd, 3rd, etc.) on a Great Building, based on a multiplier of 1.9 times the FP reward for that spot.

This calculator is primarily used by two types of players:

  • Great Building Owners: To understand how much they need to contribute to "fill" their GBs after others have placed FPs according to the 1.9 rule, ensuring their GBs level up quickly.
  • Contributors: To calculate their optimal contribution to secure valuable blueprints, medals, and Forge Points from other players' GBs without overspending.

A common misunderstanding is that the 1.9 system means contributors pay 1.9 times the *entire spot cost*. Instead, it means they pay 1.9 times the *Forge Point reward* they will receive. The GB owner then covers the remaining FPs required to complete that spot, effectively "sniping" their own GB to ensure it levels up and contributors get their promised rewards.

FoE 1.9 Formula and Explanation

The core principle of the 1.9 system revolves around a simple formula, but its application requires understanding the variables involved. The primary goal is to ensure that a contributor's investment yields a profitable return in FPs, while also providing a strong incentive for the GB owner to complete the level.

The Core Formulas:

1. Your Required Contribution (FPs):
Your Contribution = Desired Spot FP Reward × 1.9 Multiplier

This formula calculates the exact amount of Forge Points you, as a contributor, should place to earn a specific FP reward, assuming the 1.9 system.

2. Owner's Remaining FPs to Fill GB:
Owner's Remaining FPs = Total FPs for Level - Owner's Current FPs - Your Contribution

This formula helps the GB owner (or you, to assess the situation) understand how many FPs are still needed to completely fill the Great Building level after your contribution.

Variables Table:

Variable Meaning Unit Typical Range
Total FPs for Level The total Forge Points needed to complete the current level of the Great Building. FPs 10 - 100,000+
Owner's Current FPs The Forge Points already contributed by the Great Building owner. FPs 0 - Total FPs for Level
Desired Spot FP Reward The specific Forge Point reward offered by the game for the spot you wish to secure (e.g., 1st, 2nd). FPs 1 - 5,000+
Desired Spot BP Reward The Blueprint reward for the spot you are securing. Blueprints 0 - 5
Desired Spot Medal Reward The Medal reward for the spot you are securing. Medals 0 - 10,000+
1.9 Multiplier The agreed-upon factor for contributions, typically 1.9, ensuring profit for the contributor. Unitless 1.0 - 2.5

Practical Examples

Let's illustrate how the FoE 1.9 calculator works with a couple of common scenarios.

Example 1: Securing 1st Place on a New GB Level

You want to secure 1st place on a guildmate's newly leveled Great Building, which currently has no FPs. You've checked in-game, and 1st place offers a reward of 100 FPs, 2 Blueprints, and 500 Medals. The total FPs needed to complete this GB level is 1000 FPs.

Inputs:

  • Total FPs for GB Level: 1000 FPs
  • Owner's FPs Contributed: 0 FPs
  • FP Reward for Desired Spot: 100 FPs
  • Blueprint Reward for Desired Spot: 2 Blueprints
  • Medal Reward for Desired Spot: 500 Medals
  • 1.9 Multiplier: 1.9

Calculations:

  • Your Required Contribution = 100 FPs × 1.9 = 190 FPs
  • Total Current Contributions = 0 FPs (Owner) + 190 FPs (You) = 190 FPs
  • Owner's Remaining FPs to Fill GB = 1000 FPs - 190 FPs = 810 FPs

Results: You would contribute 190 FPs. You would receive 100 FPs (your reward), 2 Blueprints, and 500 Medals. The GB owner would then need to contribute 810 FPs to complete the level.

Example 2: Securing 3rd Place on a Partially Filled GB

A guildmate's Great Building (total 1500 FPs for the level) already has 500 FPs from the owner. You want to secure 3rd place. In-game, 3rd place offers a reward of 25 FPs, 1 Blueprint, and 100 Medals.

Inputs:

  • Total FPs for GB Level: 1500 FPs
  • Owner's FPs Contributed: 500 FPs
  • FP Reward for Desired Spot: 25 FPs
  • Blueprint Reward for Desired Spot: 1 Blueprint
  • Medal Reward for Desired Spot: 100 Medals
  • 1.9 Multiplier: 1.9

Calculations:

  • Your Required Contribution = 25 FPs × 1.9 = 47.5 FPs (round to 48 FPs if game doesn't allow decimals)
  • Total Current Contributions = 500 FPs (Owner) + 47.5 FPs (You) = 547.5 FPs
  • Owner's Remaining FPs to Fill GB = 1500 FPs - 547.5 FPs = 952.5 FPs

Results: You would contribute 47.5 FPs. You would receive 25 FPs, 1 Blueprint, and 100 Medals. The GB owner would then need to contribute 952.5 FPs to complete the level.

How to Use This FoE 1.9 Calculator

Using the FoE 1.9 calculator is straightforward. Follow these steps to get accurate results:

  1. Find the Great Building: Navigate to the Great Building in Forge of Empires you wish to contribute to.
  2. Note Total FPs for Level: Look at the GB's current level. The game will display the "Total FPs needed" for that level. Enter this into the "Total FPs for GB Level" field.
  3. Note Owner's FPs: Observe how many FPs the owner has already contributed. Enter this into the "Owner's FPs Contributed" field.
  4. Identify Desired Spot Rewards: Click on the Great Building and check the reward list for each spot (1st, 2nd, 3rd, etc.). Find the spot you want to secure and note down the exact Forge Point reward, Blueprint reward, and Medal reward for that specific spot. Enter these values into the respective fields ("FP Reward for Your Desired Spot", "Blueprint Reward...", "Medal Reward..."). This step is crucial for accurate calculations.
  5. Confirm Multiplier: The default multiplier is 1.9. If your guild or group uses a different agreed-upon multiplier (e.g., 1.85 or 2.0), adjust the "1.9 Multiplier" field accordingly.
  6. Calculate: Click the "Calculate" button. The results will immediately update, showing your required contribution and the owner's remaining FPs to fill the GB.
  7. Interpret Results:
    • Your Required Contribution: This is the amount of FPs you should place to secure your desired spot under the 1.9 system.
    • Owner's Remaining FPs to Fill GB: This tells the owner how many FPs they still need to place to complete the entire GB level after your contribution.
    • Blueprint/Medal Reward: These are reminders of the non-FP rewards you will receive.
  8. Copy Results: Use the "Copy Results" button to quickly grab all the calculated information for sharing with your guild or for your personal records.

Key Factors That Affect FoE 1.9 Contributions

While the 1.9 system provides a clear framework, several factors can influence your strategy and the overall effectiveness of this contribution method:

  • Great Building Level: Higher GB levels often require significantly more FPs to complete, and their reward structures can change, making accurate in-game reward lookup essential.
  • Great Building Type: Different GBs offer different rewards (e.g., Arc gives FPs, Statue of Zeus gives attack bonuses). The value of the FP reward for a spot is central to the 1.9 calculation.
  • Community Multiplier: While 1.9 is standard, some guilds or communities might use a slightly different multiplier (e.g., 1.85 for more profit for the owner, 2.0 for more profit for the contributor). Always confirm the agreed-upon multiplier.
  • Owner's Commitment: The 1.9 system relies on the GB owner "sniping" their own GB to ensure contributors receive their rewards. An uncommitted owner can leave contributors' FPs vulnerable.
  • Availability of Blueprints: For contributors, the primary goal might be to secure blueprints for their own GBs. The 1.9 system guarantees this while providing an FP return.
  • Player's Own FP Generation: Your personal rate of FP generation influences how many GBs you can contribute to and how quickly you can recover your investment.
  • Friends/Guildmates: A strong network of friends and guildmates is crucial for a thriving 1.9 thread, ensuring quick fills and reliable contributions.
  • Arc Bonus: Players with a high-level Arc Great Building receive an FP bonus on all collected rewards, making 1.9 contributions even more profitable for them.

Frequently Asked Questions about the FoE 1.9 Calculator

  • What exactly does "1.9" refer to in Forge of Empires?
    The "1.9" refers to a multiplier. It means that contributors to a Great Building place Forge Points (FPs) equal to 1.9 times the FP reward they will receive for their chosen spot. This ensures a profit for the contributor while encouraging efficient GB leveling.
  • Why is 1.9 used instead of 2.0 or another number?
    The 1.9 multiplier is a community-driven standard that strikes a balance. It provides a healthy profit for the contributor (1.9x investment for 1x return, meaning a 0.9x profit on the reward value), while still making it attractive for the GB owner to "snipe" their own GB (filling the remaining FPs) because it's cheaper than paying full price for every spot.
  • How do I find the exact FP, Blueprint, and Medal rewards for a spot?
    You must look this up directly in the game. Click on the Great Building you want to contribute to. On the GB's information panel, you'll see a list of rewards for 1st, 2nd, 3rd, 4th, and 5th place. These values change with each GB type and level.
  • What if the GB owner doesn't fill the GB after I contribute?
    This is a risk if you're not in a reliable guild or a trusted 1.9 group. In a proper 1.9 system, the owner is expected to fill their GB quickly to ensure contributors get their rewards. If they don't, your FPs are locked, and you won't receive your rewards until the GB levels. Always contribute to trusted players.
  • Can I use a different multiplier than 1.9?
    Yes, some communities or individual agreements might use slightly different multipliers (e.g., 1.85, 2.0). Our FoE 1.9 calculator allows you to adjust the multiplier to fit your specific agreement.
  • What happens if I over-contribute past the 1.9 rule?
    If you contribute more FPs than calculated by the 1.9 rule, you are essentially giving extra FPs to the GB owner, or potentially making the spot less attractive for the owner to fill. It reduces your profit margin or even results in a loss if you significantly overpay. Stick to the calculated amount.
  • Is the 1.9 system always the best way to level Great Buildings?
    For efficient, collaborative leveling, especially for higher-level GBs, the 1.9 system is highly effective. It incentivizes community participation. However, for very low-level GBs, or if you have an abundance of FPs and no active 1.9 group, other methods might be used.
  • Are there other FoE calculators available?
    Yes, there are many other calculators for Forge of Empires, such as event calculators, goods calculators, combat calculators, and more. Each helps optimize different aspects of gameplay.
