*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:

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

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

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

## Grandma & Cursor Cookie OutputEdit

### GrandmaEdit

Initially, grandma output is 4 cookies every five seconds. By buying each upgrade, this number will increase.

Building required | Grandma | Increase | Cookies/5 seconds | CpS | Stacked increase | Stacked Cookies/5 seconds | Stacked CpS |
---|---|---|---|---|---|---|---|

Factory | + 1 | 5 | 1 | + 1 | 5 | 1 | |

Mine | + 2 | 6 | 1.2 | + 3 | 7 | 1.4 | |

Shipment | + 3 | 7 | 1.4 | + 6 | 10 | 2 | |

Alchemy Lab | + 4 | 8 | 1.6 | + 10 | 14 | 2.8 | |

Portal | + 5 | 9 | 1.8 | + 15 | 19 | 3.8 | |

Time Machine | + 6 | 10 | 2 | + 21 | 25 | 5 | |

Elder Pledge | + (amount of Portals) x 0.5 | 4 + (amount of Portals) x 0.5 | 0.8 + (amount of Portals) x 0.1 | + 21 + (amount of Portals) x 0.5 | 25 + (amount of Portals) x 0.5 | 5 + (amount of Portals) x 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:

$ \text {Cookies/5 seconds} = 25 + \text {amount of Portals} \times 0.5 $

Or equivalently:

$ \text {CpS} = 5 + \text {amount of Portals} \times 0.1 $

### CursorEdit

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:

$ \text {Cookies/5 seconds} = \text {amount of Cursors} \times 1.5 $

Or equivalently:

$ \text {CpS} = \text {amount of Cursors} \times 0.3 $
