What a real private-label margin looks like after fees

Private label gets sold as a path to fat margins. The reality, after Amazon takes its cuts, is narrower — and that's normal. The trick is knowing the number before you're committed, not after.

Walk through a $30 product

Say you sell something for $30. Start subtracting:

• Referral fee: 15% of the sale, about $4.50.
• FBA fulfillment: roughly $4.41 for a standard-size item around 1–2 lb.
• Your cost (landed): say $8.
• PPC per sale: if you spend $30 to get 10 sales, that's $3.
• Returns and prep: call it $0.50.

Add the costs: $4.50 + $4.41 + $8 + $3 + $0.50 = $20.41. Profit per unit is about $9.59, or roughly 32% net. That's a healthy product.

Where it breaks

Drop the price to $22 to "win" a keyword, and the referral fee falls but everything else stays. Your profit shrinks faster than the price did, because the fee is a percentage and the rest is fixed. At $22 you might be under 10% — and one storage fee bump or a return spike puts you at zero.

The other breaker is PPC. If your real ad cost is $5, not $3, that $9.59 becomes $7.59, and the "healthy" product is mid-pack. Most margin problems trace back to an understated ad cost, not the product itself.

Why 20-35% net

Below 20%, you have almost no room for the things that go wrong: a fee increase, a slower month, a return spike. You're one bad week from red. Above 35%, you're either in a great niche or your cost number is too low. The sane target most private-label sellers actually keep is 20–35% net per unit, before tax and before fixed monthly costs like software and help.

The takeaway

Margin isn't the sale price minus your factory cost. It's the sale price minus everything Amazon and your ads take, times the units you'll really move. Run the full calculation on every product before you order, and trust the result over the optimistic version in your head.
