ACoS vs. TACoS: The Metrics Amazon Sellers Must Balance for Profit
Sep 25, 2025
Featured Snippet
TACoS (Total Advertising Cost of Sale) measures ad spend against total sales including organic revenue, while ACoS only tracks ad-attributed sales. A decreasing TACoS signals profitable growth. Aim for 5-15% TACoS. Lower it through listing optimization, targeted exact match campaigns, and ruthlessly cutting wasted spend on non-converting keywords.
Introduction
I audited a $2.8M seller last week.
TACoS: 23%. ACoS: 41%. Monthly bleed: $47,000.
They thought they had an advertising problem.
They had a profit problem.
Here's the thing—99% of sellers obsess over ACoS while their business bleeds out through TACoS. It's like checking your speedometer while your engine's on fire.
The Brutal Truth About TACoS vs. ACoS
ACoS tells you what happened.
TACoS tells you if you'll survive.
ACoS only counts ad-attributed sales. Spend $100, make $400 in ad sales, that's 25% ACoS. Looks decent on paper.
TACoS counts everything.
Same $100 spend, but you made $1,000 total (including organic)?
Now you're at 10% TACoS.
That's the difference between a business and a hobby.
I see this constantly in audits. Sellers celebrating 30% ACoS while their TACoS sits at 25%. They're essentially renting customers from Amazon at premium rates.
Not building a business.
Burning one.
Your TACoS Is High Because Your Organic Sales Suck
Let me be blunt.
If your TACoS is above 20%, you don't have an ad problem.
You have an organic problem.
Last month, I analyzed 47 accounts. The pattern was identical:
High TACoS accounts: 70%+ revenue from ads
Low TACoS accounts: 65%+ revenue from organic
The difference? About $380,000 in annual profit
When TACoS drops, three things are happening:
Your products rank organically (finally)
Customers search for your brand name (not "garlic press")
Your profit margins expand (the whole point)
One client went from 28% TACoS to 11% in four months.
Not by cutting ad spend.
By fixing what actually mattered.
Strategy #1: Your Listings Are Costing You Millions
Your main image converts at 2%.
Your competitor's converts at 5%.
You need 2.5x more traffic for the same sales.
That's not competition. That's charity.
Here's what actually moves the needle:
Images that sell: Lifestyle shots showing the product solving the exact problem. Not your logo. Not features. Solutions.
Titles that rank: Primary keyword in first 5 words. Every time. No exceptions.
Bullets that convert: Benefit first. Feature second. "Sleep through the night (10-hour battery life)" beats "10-hour battery life" every time.
I tested this with a supplements brand. Changed nothing but listing optimization:
Conversion rate: 11% → 18%
Organic rank: Page 3 → Page 1
TACoS: 19% → 12%
Time invested: 6 hours
Six hours for $240,000 in annual profit recovery.
But sellers would rather tweak bids for months.
Strategy #2: Stop Funding Amazon's Retirement Plan
Your broad match campaigns are a disaster.
I guarantee it.
Pulled a search term report yesterday. Client spending $1,200/day.
"Garlic press" triggering "garlic bread recipes"
"Water bottle" triggering "water bottle for dogs"
$18,000 monthly spend. $7,400 completely wasted.
The Exact Match Profit System:
Phase 1: Murder your broad campaigns (or bid them to the floor)
Phase 2: Extract every converting search term
Phase 3: Launch exact match at 2x the bid
Phase 4: Own the terms that actually matter
This isn't complex. It's discipline.
One electronics seller implemented this:
Week 1: Identified 847 wasted terms
Week 2: Launched 73 exact match campaigns
Week 4: TACoS dropped 4 percentage points
Week 12: $67,000 less in ad spend, same revenue

Stop gambling.
Start targeting.
Strategy #3: The Negative Keyword Gold Mine
Every search term report is a profit report in disguise.
Most sellers never look.
The ones who do, look once a quarter.
The profitable ones? Weekly. Like clockwork.
My Monday Morning Ritual:
Download search term report
Sort by spend (high to low)
Find everything with 0 sales after 20+ clicks
Add as negative. Immediately.
Reinvest savings into winners
Last Monday's audit:
312 terms bleeding money
$4,200 monthly waste
45 minutes to fix
TACoS impact: -3.2% in 30 days
Your competitors are spending $4,200 to learn what doesn't work.
You're learning for free from their mistakes.
Who do you think wins?
The $847K Case Study Nobody Believes
Outdoor gear brand. $3.2M annual revenue.
January TACoS: 24%
July TACoS: 9%
What changed?
Month 1-2: Murdered waste. Added 1,847 negative keywords. Freed up $31,000/month.
Month 3-4: Rebuilt listings. Conversion rate jumped from 9% to 14%. Organic traffic doubled.
Month 5-6: Launched Profit Feedback Loop system. Only funded keywords that drove organic rank.
The result?
$847,000 more in profit. Same revenue.
They didn't need more sales.
They needed to stop the bleeding.
Here's what pisses me off:
They'd been bleeding for 18 months. Previous agency kept saying "it takes time" and "ACoS is improving."
Meanwhile, they lost over a million in profit.
Because nobody looked at TACoS.
Your TACoS Benchmarks (Stop Guessing)
After analyzing 400+ accounts, here's reality:
0-10% TACoS: You're printing money. Don't touch anything.
10-15% TACoS: Healthy. Room to scale.
15-20% TACoS: Warning zone. Profits evaporating.
20%+ TACoS: You're working for Amazon. Fix this immediately.
New launches run higher initially. Fine.
But if you're at 25% TACoS after 6 months?
You don't have a business.
You have an expensive hobby.

FAQ: The Questions That Matter
Q: Why is my TACoS higher than my ACoS?
Your TACoS is never higher than ACoS. Ever. If you think it is, you're calculating wrong. TACoS includes all sales (organic + paid), so it's always lower than ACoS unless you have zero organic sales. Which means bigger problems.
Q: What's the fastest way to lower TACoS on Amazon?
Kill your waste. Today. Not tomorrow. Download your search term report, find every term with 20+ clicks and zero sales, add as negative keywords. I've seen TACoS drop 5% in two weeks just from this.
Q: Should I reduce ad spend to improve TACoS?
No. That's like stopping eating to lose weight. You'll die. Instead, redirect wasted spend to high-converting exact match keywords that build organic rank. Same spend, better results.
Q: How long should it take to get TACoS under 15%?
Established products: 60-90 days with proper optimization. New launches: 4-6 months. If it's taking longer, you're either in an impossibly competitive niche or doing it wrong. Usually the latter.
Q: What if my TACoS is good but I'm not profitable?
Then your margins suck or your product costs too much. A 10% TACoS means nothing if you're only making 15% margin. Fix your sourcing or raise your prices. Math doesn't lie.
Stop Bleeding. Start Profiting.
Your TACoS is telling you everything.
Most sellers just aren't listening.
The difference between sellers who exit for 7 figures and sellers who burn out?
One group treats TACoS like a religion.
The other treats it like a suggestion.
