How to make money

Denarii come from satisfied residents. GameRant and TheGamer both point at the Island Income panel, under the island’s name, as the place that shows which building is the surplus and which is the loss. Start there before you add another production chain.

Multipliers that are actually in the guides

Specialists such as Gaius Julius Lupus extend market income range. An actuary adds income on residences directly. Area buildings such as the spinner add income to buildings in range, and a building only receives that bonus once, so overlapping circles waste the second copy. A gambling house pays +3 income per building in range and costs 2 fire safety, which is why stacking them starts fires.

About the “money glitch” search

I am not hosting a trainer, a table, or a step list for infinite denarii. The official modding FAQ says mods break across updates, and memory editors break for the same reason: the next patch moves things. Legal levers in the two money guides are trade surplus, lower upkeep, and income or upkeep discoveries.

Per-building income numbers are not in those articles. The panel is. Use the panel on your save rather than a number I would have to invent.
