TACoS Tracking —
When to Scale,
When to Pause
ACoS shows campaign efficiency. TACoS shows business health. Most sellers track one and ignore the other — and that is exactly why they scale too late, pause too early, or throw money at ads that can never work.
Your ACoS looks fine. Your campaigns are running. But is your business actually growing — or are you just paying for sales that should be coming organically? TACoS is the only metric that answers this question. And most Amazon sellers have never calculated it even once.
TACoS at a Glance — What Every Range Tells You
TACoS is a traffic light for your Amazon business. Each range carries a clear signal — and a clear action. Here is the complete reference.
| Metric | Scenario A — Healthy | Scenario B — Dangerous | What to Do |
|---|---|---|---|
| Total Revenue | ₹5,00,000 | ₹2,00,000 | Pull from Seller Central Business Reports |
| Ad-attributed Revenue | ₹2,00,000 | ₹1,80,000 | Pull from Advertising Reports |
| Total Ad Spend | ₹40,000 | ₹40,000 | Same spend — different business reality |
| ACoS | 20% Looks fine | 22% Looks fine | ACoS alone does not reveal the problem |
| Organic Revenue % | 60% Healthy | 10% Critical | Key difference — organic contribution |
| TACoS | 8% Excellent | 20% Danger | TACoS reveals the real picture |
| Action | Scale budget confidently | Fix listing — pause scaling | Different decisions from same ACoS |

Four cards — TACoS formula, two real business scenarios, and a monthly tracking system you can implement today.
TACoS = Ad Spend ÷ Total Revenue × 100
Organic % = (Total Revenue − Ad Revenue) ÷ Total Revenue × 100
Ad Revenue = ₹1,80,000 (90% of total!)
Ad Spend = ₹40,000
TACoS = 40,000 ÷ 2,00,000 = 20%
TACoS flat → monitor — optimise listing
TACoS rising → listing problem — pause scaling
Calculate: ACoS, TACoS, Organic %
Falling TACoS = healthy growth → scale
| Month | Total Revenue | Ad Spend | ACoS | TACoS | Organic % |
|---|---|---|---|---|---|
| Jan | ₹3,00,000 | ₹45,000 | 30% | 15% | 50% |
| Feb | ₹3,50,000 | ₹45,000 | 28% | 12.9% | 54% |
| Mar | ₹4,20,000 | ₹48,000 | 28% | 11.4% | 60% |

Each card contains the formula, a real scenario, and a key decision guide. Here is a free preview of the core TACoS formula:
Total Revenue = Ad Revenue + Organic Revenue
Example: ₹40,000 ad spend on ₹5,00,000 total revenue = 8% TACoS — excellent. The same ₹40,000 on ₹2,00,000 total = 20% TACoS — dangerous. Same spend, completely different business health.

What You Learned in Module 4
ACoS measures campaign efficiency. TACoS measures business health. You need both — but TACoS is the one that drives scaling decisions.
Formula: Ad Spend ÷ Total Revenue × 100. Pull Total Revenue from Business Reports and Ad Revenue from Advertising Reports every month.
A falling TACoS means organic is growing — safe to increase budget. TACoS stuck above 25% after 90 days means your listing is not converting. Fix images, bullets, and reviews first.
One month of data is not enough. The direction of change is what matters. A simple monthly spreadsheet gives you the confidence to scale — or the warning to pause — before it is too late.
