Bank

The Bank is a building in Cookie Clicker and one of the later midgame structures, notable for being the first building with an initial cost above one million cookies. Like other buildings, it contributes to cookies per second and can be leveled up with sugar lumps after reaching its first level.

A leveled-up Bank is not only useful for increasing production and helping with achievements, but also because higher levels improve its interest rate. This makes it a building with value beyond raw CpS, since upgrading it can increase the return from its banking-related mechanics.

• It is the first building whose base price exceeds 1,000,000 cookies.
• After its first level, further sugar lump upgrades continue to provide benefits, including better interest rates.
• Its associated gallery assets include the Bank itself, a background, and Banker Grandma.
