The Amazon marketplace continues to accelerate, with over 11.2 million active sellers worldwide (Statista, Q1 2025), and rising competition is putting profit margins under unprecedented pressure. Amazon’s latest fee structure updates have increased FBA costs by an average of 6.8% year-over-year (Marketplace Pulse, 2025), while advertising costs continue to rise, with the average TACoS reaching 24.3% across major categories (Perpetua, 2025).
Alarmingly, 65% of Amazon sellers reported declining profitability in 2025 despite revenue growth (Jungle Scout Seller Survey 2025). This “profit paradox” makes weekly financial health checks more critical than ever.
