$746K/Month in Health & Household — What Did They Actually Keep?

A seller shared their dashboard publicly — approaching $1 million per month. $746,542 in May 2026 across 34,774 units. Health & Household. 4.55% TACOS. Five SKUs, hero-SKU focused.

The dashboard also shows a year-over-year comparison. Same month last year: $661,318 on 32,403 units. Revenue up 12.89%. ASP barely moved — $25.07 to $25.16. A nine-cent increase.

That nine cents tells a story most sellers never read.

The fee stack

Same methodology. Published rates. Nothing estimated. ASP from the dashboard: $25.16.

Fee	Per unit	Monthly	Rate card
Referral fee (15%)	$3.77	$131,098	Source
FBA fulfilment (Large Std, 8–12 oz)	$4.20	$146,051	Source
Inbound placement	$0.30	$10,432	Source
Professional plan	—	$40	Source
Platform total	$8.27	$287,621

Platform take: 38.5% of revenue. The highest in this series.

Look at the two biggest lines. The FBA fulfilment fee ($4.20) is higher than the referral fee ($3.77). At $25.16 per unit, Amazon charges more to pick, pack, and ship the product than it charges as a commission on the sale.

That's the opposite of every other seller in this series. The beauty brand at $46.66 paid $7.00 in referral and $3.95 in fulfilment — referral was nearly double. The supplements seller at $28 paid $4.20 for each. This seller at $25.16 has crossed to the other side.

The crossover

There's a price point where the referral fee and the FBA fulfilment fee are equal. For a Large Standard product at 8–12 oz, that crossover is $28.

ASP	Referral (15%)	FBA (8–12 oz)	Which dominates	Combined %
$20	$3.00	$4.20	FBA	36.0%
$25	$3.75	$4.20	FBA	31.8%
$28	$4.20	$4.20	Equal	30.0%
$30	$4.50	$4.20	Referral	29.0%
$35	$5.25	$4.20	Referral	27.0%
$47	$7.05	$4.20	Referral	23.9%

This matters because it determines which optimisation lever has the biggest impact.

Below the crossover ($28): The flat per-unit FBA fee eats the largest share. Weight reduction and packaging optimisation have the highest payoff. Pricing changes have diminishing returns because 15 cents of every extra dollar goes to the referral fee.

Above the crossover: The percentage-based referral fee dominates. Pricing strategy matters more. A $5 price increase generates $4.25 for the seller and only $0.75 for Amazon. Weight reduction still helps — but the referral fee is the bigger line to manage.

This seller at $25.16 is below the crossover. Every ounce of product weight matters more here than for a $47 beauty product. Moving from the 8–12 oz band ($4.20) to the 4–8 oz band ($3.95) saves $0.25 per unit — $8,694 per month, $104,322 per year. (Source)

Most sellers don't know which side of the crossover they're on. The answer determines which lever matters most — and it's different for every product at every price point.

The silent rate increase

The year-over-year comparison reveals something the seller may not have noticed.

The seller raised their average selling price by $0.09 — from $25.07 to $25.16. That's a 0.36% increase. Measured and conservative.

Amazon raised the FBA fulfilment fee by $0.05 per unit across every weight band for 2026. (Source)

	Seller	Amazon
Price change per unit	+$0.09	+$0.05
Share of the increase	44%	56%

Amazon captured 56% of the seller's price increase. The seller raised their price by nine cents. Five of those cents went straight to the higher FBA fee. The seller kept four cents.

At 34,774 units per month, the FBA rate increase alone costs this seller $1,739 per month — $20,868 per year. The seller didn't opt into this cost. It appeared in January when the new rate schedule took effect. No notification in the dashboard. No line item flagging the change. The rate simply updated, and every unit shipped from that point forward cost $0.05 more.

The seller's YoY comparison shows 12.89% revenue growth. It doesn't show that the platform's cut per unit grew at the same time — silently, automatically, on every unit.

What rate monitoring would show

Amazon updates its FBA fee schedule annually. The 2026 changes took effect on January 15. Every weight band, every size tier, every price band — hundreds of individual rate cells — shifted. Some went up. Some stayed flat. The inbound placement fee structure changed entirely, with new weight breakpoints and revised ranges.

A seller who doesn't track these changes per-SKU won't know the impact until it shows up in their margins — weeks or months later. A system that monitors every published rate card and recomputes the fee stack when any input changes would surface the impact on the day it takes effect. Not in the P&L review three months later. On the day it hits.

This seller's margins compressed by $0.05 per unit on January 15, 2026. They may not know it yet.

The gap

Each seller in this series is priced differently. The fee structure treats each one differently.

The beauty brand at $47 pays a platform take of 25%. This seller at $25 pays 38.5%. The same category. The same fulfilment method. Thirteen percentage points apart — driven entirely by the interaction between a percentage-based referral fee and a flat per-unit fulfilment fee.

Where your product sits relative to the crossover determines which costs dominate, which levers matter, and how much of every price increase you actually keep.

This seller's margins compressed by $0.05 per unit on January 15, 2026 — $20,868 per year — and they may not know it yet. The dashboard shows revenue. It doesn't show which side of the crossover you're on, or when the line moved.
