For Buildings in the current version of Cookie Clicker, see Buildings.

Buildings are the foundations of Cookie Clicker Classic. Buildings are items that gradually gain you more cookies for buying more buildings. Each building has an individual CpS (Cookies per Second) and increase in price each time you buy one. Cookie Clicker Classic Contains 9 buildings, including the Elder Pledge. Unlike in the newest version of Cookie Clicker, Buildings produces cookies every 5 seconds.

Each building's price is calculated with the following formula, rounded to the nearest integer:

${\displaystyle \text {Price} = \text {Base cost} \times 1.1 ^ M}$
where M = number of that type of building currently owned.

Therefore, the cumulative price for N buildings is calculated as a finite geometric series:

${\displaystyle \text {Cumulative price} = \frac { \text{Base cost} \times ( 1.1 ^ N - 1 )}{0.1}}$

Multiple copies of these items have no effect on Grandma cookie output. This allows a maximum output of 25 cookies per 5 seconds per grandma without Elder Pledge in effect.

As of the 0.1251 update, when the Elder Pledge is purchased, Grandma output increases by +0.5 for each portal purchased. Each fully upgraded grandma produces cookies according to the following formula, rounded to the nearest integer: ${\displaystyle \text {Cookies/5 seconds} = 25 + \text {amount of Portals} \times 0.5 }$

Or equivalently: ${\displaystyle \text {CpS} = 5 + \text {amount of Portals} \times 0.1 }$

### Cursor

As of the 0.1251 update, when the Elder Pledge is purchased, Cursor output increases by x1.5 for each cursor purchased. Each cursors produces cookies according to the following formula, rounded to the nearest integer: ${\displaystyle \text {Cookies/5 seconds} = \text {amount of Cursors} \times 1.5 }$

Or equivalently: ${\displaystyle \text {CpS} = \text {amount of Cursors} \times 0.3 }$

## Trivia

• Elder Pledge is considered a "building", as in the game there were no upgrades. However, it does not fully behave like one.
• Grandma Types are unlocked when you buy the related building.
• The initial cost of a time machine is all the numbers from 1 to 9.
• The Pledge grandma appears somewhat like the Portal grandma, except only having a head.
• Cursors, grandmas, and time machines are the only buildings to share a base cost with the corresponding object of the live version, as of 1.0466. As of version 2, only cursors and grandmas share a price with the corresponding building in the live version.
• No building shares its CpS with the corresponding building in the live version, however factories, shipments, and portals give 20, 100, and 6666 cookies per 5 seconds, the same as the corresponding buildings' CpS in the live version up to 1.0466. As of version 2, no buildings have this property.
• The images from the shop are very different from the ones in actual gameplay, with the exception of cursors.
