ACoS stands for Advertising cost of sale, an e-commerce & retail abbreviation.
Amazon advertising metric equal to ad spend divided by sales attributed to ads, expressed as a percentage. An ACoS of 25% means $1 of advertising produced $4 in attributed sales.

ACoS is the inverse of ROAS. Sellers compare it with their profit margin before advertising: an ACoS below that margin is profitable on attributed sales. Pronounced "AY-kos."
