What is the Arc 1.9 Calculator?
The Arc 1.9 calculator is an essential tool for players of the online strategy game Forge of Empires. It helps players determine the Forge Point (FP) rewards for contributing to other players’ Great Buildings (GBs) when they have “The Arc” Great Building, which provides a bonus to these rewards. The “1.9” refers to a common practice where players with a 90% Arc bonus (resulting in a 190% total return, or 1.9 times the base reward) contribute to each other’s GBs. This calculator helps you figure out the rewards for the top 5 contributor spots and the net cost for the GB owner.
Arc 1.9 Calculator Formula and Explanation
The formula for the Arc 1.9 calculator is straightforward. It calculates the reward for each of the top five contributor spots on a Great Building, and the total cost to the owner after these contributions.
Reward Calculation:
Reward = Base Reward for Position * Arc Bonus Multiplier
Owner’s Cost Calculation:
Owner’s Cost = Total FP to Level – Sum of Rewards for all 5 Positions
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total FP to Level | The total number of Forge Points required to level up a Great Building. | Forge Points | 100 – 5000+ |
| Arc Bonus | The percentage bonus received from “The Arc” Great Building. | Percentage or Multiplier | 1.8 (80%) to 1.9 (90%) and higher |
| Reward | The number of Forge Points a contributor receives for securing a spot. | Forge Points | Varies based on GB and level |
| Owner’s Cost | The net cost in Forge Points for the owner to level their Great Building after contributions. | Forge Points | Varies |
Practical Examples
Example 1: Leveling a Statue of Zeus
Let’s say a player is leveling their Statue of Zeus from level 9 to 10, which costs 410 Forge Points. With a standard 1.9 Arc bonus for all contributors, the rewards for the top 5 spots would be:
- P1 Reward: 75 * 1.9 = 142.5 (rounded to 143)
- P2 Reward: 25 * 1.9 = 47.5 (rounded to 48)
- P3 Reward: 10 * 1.9 = 19
- P4 Reward: 5 * 1.9 = 9.5 (rounded to 10)
- P5 Reward: 0
Owner’s Cost: 410 – (143 + 48 + 19 + 10) = 190 Forge Points
Example 2: Leveling an Observatory
A player is leveling their Observatory from level 7 to 8, at a cost of 320 Forge Points. With a 1.9 Arc bonus:
- P1 Reward: 50 * 1.9 = 95
- P2 Reward: 15 * 1.9 = 28.5 (rounded to 29)
- P3 Reward: 5 * 1.9 = 9.5 (rounded to 10)
- P4 Reward: 0
- P5 Reward: 0
Owner’s Cost: 320 – (95 + 29 + 10) = 186 Forge Points

Key Factors That Affect Arc 1.9 Calculations
- Great Building and Level: The base rewards for each position are determined by the Great Building and its current level.
- Arc Bonus Level: The higher the contributor’s Arc bonus, the higher the reward.
- “Sniping”: This occurs when a player with a higher Arc bonus contributes to a GB, taking a spot from a player with a lower bonus for a lower cost. This calculator assumes all contributors have the selected Arc bonus.
- Guild Agreements: Many guilds have specific rules about which Arc bonus levels are used for contributions.
- Rounding: Forge of Empires rounds rewards to the nearest whole number. This calculator does the same.
- Securing a Spot: A contributor must put in enough FPs to ensure no one can take their spot for a lower cost. This is often referred to as “securing” a spot.
FAQ
What is “The Arc” in Forge of Empires?
The Arc is a “Great Building” that provides a bonus to the rewards earned when a player contributes to another player’s Great Buildings.
Why is 1.9 a common standard?
A 1.9 multiplier (a 90% bonus) is a high-level Arc bonus that provides significant rewards, making it a popular and efficient way for players to help each other level their Great Buildings.
What happens if a contributor has a different Arc bonus?
If a contributor has a different Arc bonus, their reward will be different. This calculator allows you to select from a few common bonus levels to see the effect on rewards.
What is “sniping” and how does it relate to the Arc 1.9 calculator?
“Sniping” is when a player with a higher Arc bonus can secure a spot on a Great Building for fewer Forge Points than a player with a lower bonus. This calculator doesn’t account for sniping, as it assumes all contributors have the same bonus level.
Are the rewards shown in the calculator always exact?
The rewards are based on the base rewards for each position and the selected Arc bonus. The game rounds rewards to the nearest whole number, which this calculator also does.
How do I know the base rewards for a Great Building?
The base rewards for each Great Building level are fixed and can be found in the Forge of Empires Wiki or other fan-made resources.
Is it always best to use a 1.9 bonus?
While a 1.9 bonus is very efficient, the “best” bonus to use depends on your guild’s rules and the specific situation.
How does the owner’s cost get calculated?
The owner’s cost is the total Forge Points required to level the Great Building, minus the sum of the rewards received by all five contributors.
