Factory ROI formula
Mini War factories use transparent calculations: income per cycle equals production amount times resource sell value. Income per minute equals income per cycle times 60 divided by production interval. Base ROI time equals purchase cost divided by income per minute. Income per civilian equals income per minute divided by civilian slots. Income per tile equals income per minute divided by building area.
