It's very dependent. The more aggressive your guild wants to "play" in GbG (meaning: how many sectors you want to swap each 4 hours, especially on the waterfall (larger) map...) it can cost a guild doing this every 4 hours about 100,000 goods from the treasury PER DAY - or 1 million goods/10 day season. This 100K/day is a rough gauge for you swapping the map with someone else (1 other guild), that's one of the most costly scenarios. If you're swapping 1/2 of the map (North/South with a swap partner guild, while East/West is done by 2 OTHER guilds...), it's more reasonable that 100K/day.
Yes there are many swap designs. Serpentine, Checkerboard, Quadrant, etc. Some are more costly than others, and it also depends on how deep you choose to go toward the edge of the board. Most swaps concentrate on Ring 1-3, and a bit of 4. The less you swap actively, the less expense you incur.
As Inno is constantly changing GbG to surreptitiously remove buildable slots (to create
more attrition for players), so this 100K cost could have cooled a bit. But those number were accurate to the GbG "original/old map" and held up when the new map (waterfall) was introduced. I found 100K/day as consistently quoted math for many of the Sr. Diamond guilds I played in, and what leadership communicated about their own treasury draw.
You can't do this type of Sr. Diamond class playing as a guild, without understanding and strategically planning where your input comes from. If you choose to use an EI GbG game design, (EI = Era Islands goods generation), much of the problem evaporates, because you move to both known production, and known draw. Much easier to manage that, mathematically.
Why?
Simply because when GBG starts, it checks each member of the guild for era. GbG WILL NOT allow goods to be taken from the treasury for ANY buildings or use in an ERA - IF there are 0 members of the guild are in that ERA. If just 1 member is in an era, that era is now fair game for treasury draw for building costs in GbG.
So, with that in mind, here's what Era Islands did.
EI comes in 3 classes:
1) Perfect - all guild members are in the
SAME era
2a) Strong: Guild members choose just a few (1-4) eras, with 4 members as a minimum in EACH era.
2b) Managed: Guild members suggest they'd like to move UP-ERA, and their timing to do so is optimzed in the EI framework.
When anyone, can be in any era, at any time, you're potentially increasing the risk of your swaps stopping because you can't fund the buildings if you have randomly obtained a serious draw for an SC from an underfunded type of good, each 4 hours.
In EI - an era can have at a safe minimum,
3-4 people depending on the robustness of the GB generation, and their trinkets (those smaller non-GB buildings that make guild goods...).
Trinkets, surprisingly, added nearly
23K goods each day of the 120K we made each day, in a mature guild of 51 people with the lower EI era being Industrial.
Here's a quick snapshot of our 51 people, and their generation by buildings - on 1/3/22:
1/3/22 | Arc + OBS = 90,510 | Arc, Obs + Atom = 95,860 | Trinkets = 23,505 | Total/day 119,365 |
Just so you know or conversely, as you might expect..., the multiple Level 8 SOH's in each members city made 19,000 of the 23,505 each day (80%). We were SOH heavy, for sure. Level 7 SOH's delivered about 1200 goods more, as well.

PS: This is actual GB/trinket data/day.
It doesn't include ANY voluntary goods manually donated, which was an rough average BOOST of 2-3K more (over time) to the 119,365/day (meaning, 121-122K/day). Member in our guild were EXCEEDINGLY selfless in that regard - always dropping in goods to the treasury, tacitly.
