Amazon TACOS Guide
Amazon TACOS, or Total Advertising Cost of Sales, is ad spend divided by total revenue. Unlike ACOS, which only evaluates ad-attributed sales, TACOS shows whether advertising is improving the whole business, including organic sales, repeat orders, and total SKU growth.
TACOS vs ACOS
- ACOS is tactical: keyword-level and campaign-level efficiency.
- TACOS is strategic: total revenue impact and growth quality.
- ACOS can improve while TACOS worsens if organic sales fail to scale.
TACOS Decision Matrix
| Signal | Meaning | Action |
|---|---|---|
| ACOS stable and TACOS falling | Ads may be supporting organic growth | Maintain spend and monitor margin |
| ACOS improving but TACOS rising | Ad efficiency is improving but total sales are not scaling | Review organic rank, conversion, and product demand |
| TACOS rising with flat total revenue | Ad spend is not creating incremental growth | Cut low-contribution campaigns and review search terms |
| TACOS high during launch with rank movement | Possible short-term growth investment | Set a time-boxed test and margin guardrail |
Set TACOS Targets by Stage
- Launch stage: tolerate higher TACOS while building rank and review velocity.
- Growth stage: TACOS should trend down as organic sales contribute more.
- Mature stage: keep TACOS within profit guardrails and cashflow limits.
Weekly Review Loop
- Track 7-day and 28-day TACOS trends to avoid reacting to noise.
- Review organic share, repeat-order mix, and ranking movement together.
- Use the profit calculator to align TACOS decisions with break-even ACOS and net-margin thresholds.
- If TACOS rises without organic growth, cut low-contribution terms first.
Common Mistakes
- Chasing low ACOS while ignoring total sales and organic contribution.
- Overreacting to short promotion windows before trend confirmation.
- Reviewing TACOS only at account level and missing SKU-level loss pockets.
Takeaway
ACOS and TACOS should be used together. ACOS manages tactical efficiency. TACOS validates long-term growth quality. Margin modeling should remain the final decision layer before scaling spend.
FAQ
What is Amazon TACOS?
Amazon TACOS is total ad spend divided by total revenue. It shows how much total sales rely on advertising, not just how efficient ad-attributed orders are.
What is a good TACOS?
A good TACOS depends on product margin, launch stage, repeat purchase behavior, and organic sales share. It should generally trend down as a product matures.
Can ACOS improve while TACOS gets worse?
Yes. ACOS can improve inside campaigns while total revenue stays flat or organic sales decline. That is why TACOS should be reviewed with total sales and margin.
How often should TACOS be reviewed?
Review 7-day and 28-day trends weekly. Avoid making large decisions from one noisy day unless there is a clear spend anomaly.
