If you’re selling on Amazon—or thinking about it—there’s one thing that will make or break your success:
Your margins.
Not your product. Not your listing. Not even your ads.
👉 Your ability to accurately calculate profit.
The problem?
Most Amazon sellers are guessing.
Why So Many Amazon Sellers Get Profit Wrong
I’ve worked with both new and established Amazon sellers, and I see the same issue time and time again:
They calculate profit like this:
Sell Price – Product Cost = Profit
That’s it.
But this completely ignores:
Amazon fees
PPC spend
VAT (for UK sellers)
Shipping & import costs
Which means…
👉 Products that look profitable are often barely breaking even—or losing money.
The Real Cost of Selling on Amazon (UK)
To understand your true profitability, you need to factor in:
Product cost (including packaging & currency fees)
Shipping & import costs
Amazon fees (referral + FBA)
PPC cost per sale
VAT (20% in the UK)
Reimbursements (often overlooked)
Miss any of these, and your numbers are wrong.

Why I Created This
When I started my Amazon journey, I nearly made the same mistake most sellers do:
👉 Underestimating costs.
Coming from a sales background helped—but I still had to learn how Amazon’s fee structure really works.
Since then:
I scaled my brand to £2M+ turnover
Built a portfolio of 23 products
Successfully exited in 2020
Now, I help other sellers avoid those same mistakes. Check out My Services
