Great Building Leveling Calculator

What is a Forge of Empires Great Buildings Calculator?

A Forge of Empires Great Buildings Calculator is an essential tool for any serious player looking to efficiently level up their Great Buildings (GBs). In Forge of Empires (FoE), Great Buildings are monumental structures that provide significant bonuses to your city, ranging from increased production and military boosts to additional Forge Points (FPs) and goods. Leveling these GBs requires a substantial investment of Forge Points, which can be contributed by the owner and other players.

This Forge of Empires Great Buildings Calculator helps players determine the optimal distribution of Forge Points for a specific GB level. It calculates how many FPs the GB owner needs to contribute to “secure” the level (i.e., cover the rewards given to contributors) and how many FPs each of the top five contributors should put in to receive their rewards at a predetermined rate, often referred to as “1.9,” “1.92,” “1.93,” “1.95,” or “1.98” threads.

Who Should Use This Forge of Empires Great Buildings Calculator?

• GB Owners: To plan their leveling strategy, ensure they don’t overspend, and attract contributors by offering fair rates.
• Contributors: To quickly identify how many FPs to put into a GB to secure a specific reward spot at a desired rate.
• Guild Leaders: To manage guild GB leveling threads and ensure fair play and efficient progress for all members.
• New Players: To understand the mechanics of GB leveling and contribution, helping them make informed decisions early on.

Common Misconceptions about Forge of Empires Great Buildings Calculator

One common misconception is that a Forge of Empires Great Buildings Calculator eliminates the need for personal judgment. While it provides precise numbers, market conditions, guild rules, and personal goals still influence the best strategy. Another misconception is that higher contribution rates (e.g., 1.98) are always better. While they offer more profit to the contributor, they also require the owner to put in more FPs, which might not always be feasible or desirable.

Forge of Empires Great Buildings Calculator Formula and Mathematical Explanation

The core of the Forge of Empires Great Buildings Calculator lies in balancing the total Forge Points required for a level with the rewards given to contributors, adjusted by the owner’s Arc bonus and the desired contribution rate.

Step-by-step Derivation:

1. Determine Arc Multiplier: Your Arc Great Building significantly boosts the FP rewards you receive from contributing to other players’ GBs. This bonus also applies to the rewards you give out.
   Arc Multiplier = 1 + (Your Arc Bonus Percentage / 100)
2. Calculate Actual Rewards: Multiply the base FP rewards for each place (1st, 2nd, 3rd, 4th, 5th) by your Arc Multiplier. These are the FPs that contributors will actually receive.
   Actual Reward (Nth Place) = Base Reward (Nth Place) * Arc Multiplier
3. Calculate FPs for Each Contributor Spot: This is where the “rate” (e.g., 1.9, 1.95) comes in. This rate signifies that for every 1 FP a contributor puts in, they expect to get 1.9 FPs back (1 FP original investment + 0.9 FP profit). Therefore, the profit portion is (Rate - 1). To find out how many FPs a contributor needs to put in for a spot, you divide the actual reward by this profit portion.
   FPs for Nth Spot = Actual Reward (Nth Place) / (Contribution Rate - 1)
4. Calculate Total FPs from Contributors: Sum up the FPs required for all five contributor spots.
   Total FPs from Contributors = FPs for 1st Spot + FPs for 2nd Spot + FPs for 3rd Spot + FPs for 4th Spot + FPs for 5th Spot
5. Calculate Owner’s FPs to Secure Level: Subtract the total FPs expected from contributors from the total FPs needed to complete the level. This is the amount the owner must contribute to ensure the level is completed without losing FPs.
   Owner's FPs Needed = Total FPs Required for Level - Total FPs from Contributors

Practical Examples (Real-World Use Cases) for Forge of Empires Great Buildings Calculator

Understanding how to use the Forge of Empires Great Buildings Calculator with real numbers is key to mastering your GB strategy.

Example 1: Leveling an Arc to 80

You are leveling your Arc from level 79 to 80. This level requires 1900 FPs. Your Arc is currently at level 70, giving you a 170% bonus. The base rewards for this level are: 1st: 150 FPs, 2nd: 75 FPs, 3rd: 30 FPs, 4th: 15 FPs, 5th: 8 FPs. You want to offer a 1.92 contribution rate to attract contributors.

• Inputs:
  • Total FPs Required: 1900
  • Arc Bonus Percentage: 170
  • Base Reward 1st: 150
  • Base Reward 2nd: 75
  • Base Reward 3rd: 30
  • Base Reward 4th: 15
  • Base Reward 5th: 8
  • Contribution Rate: 1.92
• Outputs (from Forge of Empires Great Buildings Calculator):
  • Owner’s FPs to Secure Level: 1000 FPs
  • FPs for 1st Place Contributor: 312.5 FPs
  • FPs for 2nd Place Contributor: 156.25 FPs
  • FPs for 3rd Place Contributor: 62.5 FPs
  • Total FPs from Contributors: 900 FPs (approx)
• Interpretation: You need to put in 1000 FPs yourself. The remaining 900 FPs will come from contributors who will get a 1.92x return on their investment. This ensures your Arc levels up efficiently while providing good returns for your guildmates.

Example 2: Leveling a Castel del Monte for Goods

You are leveling your Castel del Monte from level 10 to 11. This level requires 500 FPs. Your Arc is at level 80, giving you a 190% bonus. The base rewards for this level are: 1st: 30 FPs, 2nd: 15 FPs, 3rd: 5 FPs, 4th: 2 FPs, 5th: 1 FP. You want to offer a standard 1.9 contribution rate.

• Inputs:
  • Total FPs Required: 500
  • Arc Bonus Percentage: 190
  • Base Reward 1st: 30
  • Base Reward 2nd: 15
  • Base Reward 3rd: 5
  • Base Reward 4th: 2
  • Base Reward 5th: 1
  • Contribution Rate: 1.9
• Outputs (from Forge of Empires Great Buildings Calculator):
  • Owner’s FPs to Secure Level: 350 FPs
  • FPs for 1st Place Contributor: 96.67 FPs
  • FPs for 2nd Place Contributor: 48.33 FPs
  • FPs for 3rd Place Contributor: 16.11 FPs
  • Total FPs from Contributors: 150 FPs (approx)
• Interpretation: You need to contribute 350 FPs. The remaining 150 FPs will be covered by contributors at a 1.9 rate. This is a common scenario for smaller GBs or lower levels where the owner covers a larger portion.

How to Use This Forge of Empires Great Buildings Calculator

Using our Forge of Empires Great Buildings Calculator is straightforward and designed to help you quickly get the information you need for efficient GB leveling.

Step-by-step Instructions:

1. Input Total FPs Required for Next Level: Find this information on your Great Building’s detail screen in FoE, or on a FoE wiki. Enter it into the first field.
2. Enter Your Arc Bonus Percentage: Check your Arc’s current level and its corresponding bonus percentage. An Arc at level 80 gives a 90% bonus, so you’d enter “90”.
3. Input Base FP Rewards (1st-5th Place): These are the standard rewards for the current GB level, visible on the GB’s detail screen. Enter them for each place.
4. Select Desired Contributor Rate: Choose the rate at which you want contributors to profit. Common rates are 1.9, 1.92, 1.93, 1.95, or 1.98. This is often dictated by guild rules or community standards.
5. View Results: The calculator will automatically update as you input values. The “Owner’s FPs to Secure Level” will be prominently displayed, along with the FPs needed for each contributor spot and the total FPs from contributors.
6. Use the Chart: The dynamic chart provides a visual breakdown of the FP distribution, helping you quickly grasp the overall picture.
7. Reset or Copy: Use the “Reset” button to clear all fields and start over with default values. Use the “Copy Results” button to easily share the calculated values with your guild or friends.

How to Read Results:

• Owner’s FPs to Secure Level: This is the minimum amount of FPs you, as the GB owner, need to contribute to ensure the level is completed and all contributor rewards are covered. If this number is negative, it means the total rewards (after your Arc bonus) exceed the total FPs needed for the level, which is highly unlikely unless you have an extremely high Arc and very low level GB.
• FPs for Nth Place Contributor: These are the exact FPs a player needs to put into your GB to secure that specific spot and receive their reward at the chosen contribution rate.
• Total FPs from Contributors: The sum of FPs expected from the top 5 contributors.

Decision-Making Guidance:

The Forge of Empires Great Buildings Calculator empowers you to make informed decisions. If the “Owner’s FPs to Secure Level” is too high for your current FP budget, you might consider:

• Waiting until you have more FPs.
• Asking guildmates for a lower contribution rate (if allowed).
• Focusing on other GBs first.

Conversely, if your owner FPs are very low, it indicates a highly attractive GB for contributors, making it easier to level up quickly.

Key Factors That Affect Forge of Empires Great Buildings Calculator Results

Several critical factors influence the output of a Forge of Empires Great Buildings Calculator and, consequently, your GB leveling success. Understanding these can help you optimize your strategy.

• Total FPs Required for Level: This is the most fundamental factor. Higher levels and certain GBs (like the Arc or Zeus) require significantly more FPs, directly increasing the total FPs needed from both owner and contributors.
• Your Arc Bonus Percentage: The Arc is arguably the most important GB for leveling others. A higher Arc bonus means the actual FP rewards for contributors are higher. This, in turn, means contributors need to put in fewer FPs to get their desired return, making your GB more attractive and reducing the FPs you, as the owner, need to contribute. This is a core component of any effective Arc bonus calculator strategy.
• Base FP Rewards for Each Place: These rewards vary greatly by GB and level. GBs with higher base rewards naturally require less owner contribution and are more appealing to contributors.
• Desired Contribution Rate (e.g., 1.9, 1.95): This rate dictates the profit margin for contributors. A lower rate (e.g., 1.9) means contributors get less profit, so they need to put in more FPs for a given reward, reducing the owner’s burden. A higher rate (e.g., 1.98) means contributors get more profit, requiring them to put in fewer FPs, but increasing the owner’s FPs needed. This is a crucial aspect of Forge Points strategy.
• Blueprint Availability: While not directly calculated, the need for blueprints for higher levels can influence which GBs you prioritize. If you lack blueprints for a specific GB, even with optimal FP calculations, you can’t level it. This often leads to GB blueprint trading.
• Guild Dynamics and Community: The willingness of your guildmates and friends to contribute to your GBs at specific rates is vital. A supportive community makes leveling much easier. Maintaining a good FoE friends list and guild is beneficial.
• Current FP Economy: The overall availability of FPs in your world can affect how quickly GBs get filled. During events or periods of high FP generation, GBs might fill faster.

Frequently Asked Questions (FAQ) about Forge of Empires Great Buildings Calculator

Q: What is the “1.9” rate in FoE GB leveling?

A: The “1.9” rate (or 1.92, 1.93, 1.95, 1.98) refers to the multiplier of FPs a contributor expects to receive back for every FP they invest. For example, at a 1.9 rate, if a contributor puts in 100 FPs, they expect to receive 190 FPs in rewards (100 FPs original investment + 90 FPs profit). This is a common agreement in guild leveling threads.

Q: Why is my Arc bonus so important for the Forge of Empires Great Buildings Calculator?

A: Your Arc Great Building provides a significant bonus to the FP rewards you receive when contributing to other players’ GBs. Crucially, this bonus also applies to the rewards you give out when your own GB is leveled. A higher Arc bonus means the actual FP rewards for contributors are higher, making your GB more attractive and reducing the FPs you need to put in to cover those rewards.

Q: Can I use this Forge of Empires Great Buildings Calculator for any Great Building?

A: Yes, this Forge of Empires Great Buildings Calculator is universal. You just need to input the correct “Total FPs Required for Next Level” and the “Base FP Rewards” for the specific GB and level you are working on. These values can be found in-game or on FoE wikis.

Q: What if the “Owner’s FPs to Secure Level” is a negative number?

A: A negative number for “Owner’s FPs to Secure Level” means that the total FPs from contributors (at the specified rate and with your Arc bonus) would exceed the total FPs needed for the level. This is highly unusual and typically indicates an error in input (e.g., incorrect base rewards or an extremely high Arc bonus for a very low FP cost level). Double-check your inputs.

Q: How do I find the “Total FPs Required for Next Level” and “Base FP Rewards”?

A: In Forge of Empires, click on your Great Building, then click the “Level Up” button. You will see the total FPs required for the next level and the base FP rewards for 1st, 2nd, 3rd, 4th, and 5th place. Alternatively, FoE wikis provide comprehensive tables for all GBs and levels.

Q: Should I always aim for the lowest “Owner’s FPs to Secure Level”?

A: Not necessarily. While minimizing your own FP investment is often a goal, sometimes offering a slightly higher contribution rate (e.g., 1.95 instead of 1.9) can attract contributors faster, especially for high-level GBs. The optimal strategy balances your FP budget with the speed of leveling and the needs of your guild. This is part of a broader FoE GB leveling guide.

Q: What are the typical ranges for Arc bonus percentages?

A: An Arc at level 0 gives 0% bonus. An Arc at level 80 gives a 90% bonus (1.9x multiplier). The maximum Arc level is 180, which gives a 190% bonus (2.9x multiplier). Most active players aim for Arc level 80 as a significant milestone.

Q: Does this calculator account for blueprints or goods?

A: No, this Forge of Empires Great Buildings Calculator focuses solely on Forge Point distribution. Blueprints and goods are separate requirements for leveling GBs and are not factored into the FP calculations.
