Quick question before we start. How much money did you actually make on Amazon last month?
Most sellers can’t answer that in a way they’d bet on. They can tell you their sales. They can tell you what hit their bank account. But “did I actually make money, and on which products?” — that one gets a shrug. If that’s you, you’re not behind. You’re just running into the thing Amazon was never built to tell you.
Your sales number and your bank deposit are both lying to you
There are two numbers every seller reaches for, and neither one is profit.
Your sales number is what customers paid you. It says nothing about what Amazon took out, what your product cost, or what you spent on ads. It’s the top of the funnel, not the bottom.
Your bank deposit feels more honest — it’s real money that actually landed. But it’s a bundle: sales, fees, refunds, ad charges, and account adjustments all mashed together into one biweekly net, before your product cost is ever considered. It’s cash flow, not profit. You can have a healthy deposit and still be losing money on half your catalog.
Profit is a third number neither of those shows you. This whole course is about finding it.
The fees are bigger than you think, and you’re probably not tracking most of them
Once you add in advertising, roughly 30 to 45% of your selling price disappears into Amazon fees. Not your product cost. Just the fees.
And there are more of them than almost anyone tracks. Most sellers add up the referral fee and the FBA fulfillment fee, call it a day, and quietly miss the rest. The result is a profit estimate that’s off in your favor, every single month, until something forces you to look closer.
A healthy “overall margin” hides individual products that lose money
Here’s the part that should bother you. Even if your account looks profitable overall, that average can be hiding products you are literally paying Amazon to sell.
A 15% overall margin sounds fine. But “overall” is an average, and an average can have winners propping up losers. You will never see the losers from the top-line number. You only see them when you go product by product — which is exactly what this course will teach you to do, and the moment most sellers say “I had no idea that one was bleeding.”
Your product cost lives entirely outside Amazon
Last one, and it’s the reason Amazon can never just hand you your profit.
Amazon knows what it paid you and what it charged you. It does not know what your product cost you to buy or make. That number never touches their system. They don’t know if your $30 item cost you $4 or $24 — so they literally cannot calculate your real profit. Only you have that piece.
That’s not a flaw you can fix inside Amazon. It’s a gap you have to fill yourself, which is exactly where the next module starts.
Try this in your account
Open your Seller Labs MCP and ask:
“Show me my total sales last month, my total payout last month, and payout as a percentage of sales, for my main venue.”
Look at that percentage. For most sellers it lands somewhere around 55 to 70% — meaning Amazon’s fees and ads alone eat 30 to 45 cents of every sales dollar before your product cost is even in the picture.
Then sit with the follow-up:
“And that’s before I subtract what the product cost me. So what’s actually left?”
That uneasy feeling is the right one. It’s also fixable. The rest of this course is how.
