About This GB FOE Calculator
This GB FOE calculator helps you plan great building investment spots before you add forge points. It is made for players who want clear numbers, fair rewards, and fast planning. The tool compares the target level cost with current progress. It then checks each reward spot with your Arc bonus and desired profit.
Why It Helps
Great building trades can become confusing. A small mistake can reduce profit. It can also leave the owner with an unexpected final cost. This page keeps the process simple. Enter the level cost, the points already placed, and the reward values. Add your Arc bonus. Choose a lock target. The table shows suggested contribution, reward payout, profit, and remaining owner balance.
Advanced Planning
The calculator supports five reward spots. It also allows custom rounding. This matters because different groups may prefer rounded, floored, or ceiled values. A desired profit option helps investors set a safe margin. The lock target lets you reduce the contribution by a set percent. This can support private swaps, guild rules, or low risk agreements.
Owner View
Owners can use the final balance column to know how many points are still needed. This is useful before opening a level to friends or guild members. It also helps when a building is close to leveling. You can compare current progress with planned external contributions. Then you can decide how much to add yourself.
Investor View
Investors can review reward payout and expected gain before placing points. They can test several Arc bonus values. They can also change desired profit. This is helpful for players with different Arc levels. It is also useful when a guild runs many threads. Faster checks reduce delays and improve trust during active swaps.
Good Practice
Always compare the result with the live game screen. Building costs, reward spots, and existing contributions must match. Use the example table as a guide only. Export the result when you want to share a plan with your group. CSV is helpful for spreadsheets. PDF is better for quick records.
Final Note
This calculator does not replace guild rules. It gives a clean estimate. Use it with clear communication. Confirm every spot before placing forge points.
FAQs
What is a GB FOE calculator?
It is a planning tool for great buildings in Forge of Empires. It estimates rewards, contributions, profit, and owner balance for each reward spot.
What does Arc bonus mean?
Arc bonus is the extra reward percentage from The Arc. A 90% bonus means the base reward is multiplied by 1.90 before rounding.
Why is owner balance important?
Owner balance shows how many forge points the building owner still needs after planned investor contributions. It helps avoid accidental leveling mistakes.
Can I use this for all great buildings?
Yes. Enter the correct total cost and reward spots from the game screen. The calculator works with any great building level.
What is desired profit?
Desired profit is the amount an investor wants to keep after placing points. Higher profit lowers the suggested contribution for each spot.
What does lock target percentage do?
It reduces or keeps the suggested contribution by a percentage. Use 100% for full value, or lower values for safer profit planning.
Why are rounding options included?
Different groups may prefer different rounding styles. Round, floor, and ceil help you match your guild or swap thread rules.
Should I confirm values in the game?
Yes. Always check the live game screen before placing points. Existing contributions and level costs must match your calculator inputs.
