GB Calculator
This tool helps you level your Great Buildings using a 1.9 support (or any custom value).
It calculates how many Forge Points (FPs) you need to invest to secure supporter spots, allows you to copy contribution values to the clipboard for sharing in chat, and checks if supporters have contributed correctly.
Menu Overview
The Self-Contribution Calculator interface is structured top-to-bottom as follows:
Header menu
Building name
Owner info including a link to the player's page on foe.scoredb.io
Current level & target level – Use the arrow to simulate future levels
Buttons to toggle reward percentages
Table breakdown:
Sequence – Who contributes when; e.g., owner starts with 28,862 FP to secure 1st and 2nd places
FPs – Required contribution
Done – Already contributed amount
Blueprints – Received from contribution with current Arc bonus
Medals – Received from contribution with current Arc bonus
Ext – Detects externally filled positions and arranges them
Arc – Arc bonus percentage per spot, editable per spot (eg. 1st and 2nd to be set as 2.0 contribution)
Key values:

Usage
As soon as you start investing Forge Points into your GB, the calculator will recognize it. Once you've contributed some FPs, they will appear under Done. For example, after contributing 19,476 FP, continue until the value under FPs in the first row reaches 0 (to be added by owner 28,862 FPs) After the contribution of the remaining value, P1 and P2 will be secure and can be filled by others.
Next, continue with the next row (e.g., 604 FP). Always go in order — top to bottom — to ensure the GB remains secure from sniping:
If a Donator overpays or your GB is in the "push zone" (roughly levels 30–60), where no self-contribution is required to secure places, Donator spots may be vulnerable.
A sniping attacker could claim a spot by contributing less than the required amount and still not be overtaken.
In that case, a red warning message appears: danger (xxFP) – showing how much profit a sniper would gain.
In the example below, a sniper could profit 327 FP. You would need to contribute those yourself to secure the spot:
