Amazon FBA case studies

• This Liquid Vitamin Brand Does $8.15M/Month In Profit On Amazon — MaryRuth's · Their first Amazon listing predates their website's domain by four months — and they built outward from there.

About $7.61 of every $19.52 sale is left, even with Amazon taking 46% of what it sells. · $282,931 profit/mo · 39% margin · $725,873 revenue/mo · about $948 to launch your own, plus fixed costs for a new brand · 15.5 years old

• The Kids' Science Kit Brand Clearing $156.2K/Month In Profit — Doctor Jupiter · Ninety-two listings, but one kit for four-year-olds — boys' and girls' boxes in three editions — made 61% of September.

• This Mahjong Brand Does $91.8K/Month In Profit on Amazon — Virora Mahjong · None of 48 sponsored slots on four searches was theirs, not even on their own brand name.

• How a Montessori Toys Brand Does $49.4K/Month In Profit — KALOTOYS · Their own name is on none of the seller accounts — three US storefronts sell the catalogue — and four name puzzles they listed in March 2026 are now over half of a month's Amazon revenue. · $49,358 profit/mo · 32% margin · $156,692 revenue/mo · about $897 to launch your own, plus fixed costs for a new brand · 2 years old
• How A $12.99 Deck Of Cards Clears $37.2K/Month In Profit — Spite House Games · They built the audience first: the TikTok account opened seven weeks before the first deck was listed, and it now carries 45,400 followers.

• How A Set Of Bamboo Spoons Clears $18.5K/Month In Profit — WOODLANDS USA · Sets titled for film franchises, with no licence shown, made 56% of a $307K December.

• How A $36.99 Baptism Gift Set Does $14K/Month In Profit — Highmark Collective · They have no social accounts anywhere and their own Shopify store charges more than Amazon does, so Amazon US is effectively the whole business — eight listings they are the only seller on, running on a modelled 2.4% of revenue in ads. · $14,030 profit/mo · 27% margin · $51,482 revenue/mo · about $13,815 to launch your own, plus fixed costs for a new brand · 8 months old

• How A $37.50 Activity Doll Clears $7.3K/Month In Profit — Bizzikins · They spend almost nothing on ads — about 0.2% of sales, mostly on long-tail phrases — and let four characters at one price carry the listing.

• Started on Kickstarter doing Board Games, Now $7.3K/Month In Profit On Amazon — Restoration Games · Eight years after its first Kickstarter, it was still leaving Amazon to resellers — until November 2025, when it began selling its own listings.

• How A $24 Scratch-Off Golf Game Clears $6.1K/Month In Profit — Gamblin' Golf · Their first golf betting game was a December gift — 1,000 sold in December 2024, then too few to register for most of 2025.
