TACOS = (Ad Spend ÷ Total Sales) × 100. Unlike ACOS, TACOS shows how advertising affects your entire business, including organic sales. Track TACOS over time to see if ads are scaling the whole brand profitably.

How it works

1

Enter ad spend

Total Amazon PPC spend for the period.

2

Enter total sales

All sales (organic + ad attributed) for the same period.

3

Read your TACOS

TACOS shows overall ad efficiency. A falling TACOS with rising sales means ads are working.
