Every building and upgrade price we have read in the CONSTRUCTION menu (B), with the HQ level it needs and what it adds. Prices keep the game's own rounding, so $12.0K may not be exactly 12,000.

Reading the table
Bought means we built it and saw the result. Quote means we read the price and effect on the card but did not buy it. Income is what that purchase adds, exactly as the card says (“Upgrade: +9/s base income”).
HQ level 3/5: the next upgrade costs $1.00M for +24/s and unlocks tier 4.
