The general formula for a cycloalkane is CnH2n.

Explanation:

On the other hand, the general formula of an alkane is CnH2n+2. In cycloalkanes, the ring junction, the extra CC bond has reduced the hydrogen count by 2.

Chemists speak of degrees of unsaturation with respect to organic formulae. Alkanes are conceived to be saturated, and each 2 hydrogens less than the saturated formula corresponds to a so-called degree of unsaturation. See here for further explanation.
