   1 · How we calculate it

   Ad-attributed sales divided by ad spend, on Amazon.

   Amazon ads ROAS=Ad-attributed sales÷Ad spend

   We divide the sales Amazon credits to your ads by your Amazon ad spend, over the last 12 complete months.

   Amazon decides which sales an ad gets credit for. We keep its default attribution windows.
