Anyone care to share the build cost formula? I know it was posted somewhere but i cant seem to find it (and im lazy)

Old:
3*land+1500

New:
3*(max(1,land-1500)^1.05)+1500


max(1,land-1500) means the larger number out of (1) and (land-1500). Yes, this means constructions costs are constant until you reach 1501a acres, and you should explore whenever you can to 50% built while under 1500a.


At 100 acres: Old $1800, New $1503
At 500 acres: Old $3000, New $1503
At 1000 acres: Old $4500, New $1503
At 1500 acres: Old $6000, New $1503
At 1600 acres: Old $6300, New $1877
At 1700 acres: Old $6600, New $2282
At 1800 acres: Old $6900, New $2697
At 1900 acres: Old $7200, New $3119

At 4541 acres, the old and new costs become the same (at $15123), and from then 4541 acres onwards, the new construction costs overtakes and increases exponentially compared to the old costs.

At 20k acres, building costs are roughly 50% larger than the old.
At 30k acres, building costs are roughly 58% larger than the old.
It just gets worse from here.

Thanks.

I'm trying to figure out when do I stop getting build cost bonus and go for food booms instead.

I'm still struggling to figure that out since i don't know what acreage to stop at, and how food prices are going to be

Has anyone been successful with using the decay bonus? It seems if one is really good at accessing the bonus, you can get decay to zero with about 10 days left of the set.

Yes, many countries have used it to avoid stocking food. But at the risk of holding 20b cash at home and being topfed.

And getting cash stolen through spy ops
