Frequently Asked Questions
How do I calculate Amazon FBA profit?
Amazon FBA profit per unit = Selling Price − Product Cost − Inbound Shipping − FBA Fulfilment Fee − Referral Fee − Storage − PPC Cost per unit. The biggest levers are FBA tier (weight/size), referral fee (8–20% of price), and COGS. Target 20–35% net margin after all costs.
What are Amazon FBA fees in 2026?
FBA fees start at $3.22 for Small Standard (≤ 15 oz) and go up to $7.42 for Large Standard (≤ 20 lb). Small Oversize (≤ 70 lb) is $9.73, Medium Oversize $19.05, Large Oversize $89.98. Plus a referral fee of 8–20% depending on category. Total Amazon fees are typically 25–35% of the selling price.
What is a good Amazon profit margin?
Target 20–35% net margin after all costs. Below 15% is fragile — returns, promotions, or rising PPC costs can quickly turn profitable products unprofitable. Private label brands with strong brand equity and low advertising dependency typically achieve 30–50% margins.
What is TACOS and why does it matter more than ACoS?
ACoS measures ad spend against PPC-attributed revenue only. TACOS measures ad spend against total revenue including organic. TACOS is the true health metric: a declining TACOS means your ads are driving compounding organic rank gains — the goal of every Amazon PPC strategy. Elite brands target TACOS below 8%.
How do I improve my Amazon ROI?
Three levers: (1) Reduce COGS through manufacturing negotiation or sourcing alternatives. (2) Lower ACoS through bid optimisation and negative keyword discipline. (3) Increase selling price through listing quality improvements — A+ Content, main image testing, review velocity. The highest-ROI lever is typically listing conversion rate: a 1% CVR lift generates more revenue than a 20% traffic increase at zero additional cost.
