Referral Fee

= $4.50

Amazon charges a referral fee (% of sale price) varying by category. Typical range: 8–15% for most; 45% for Amazon Device Accessories.

FBA Fulfillment Fee

= $3.22

Pick-and-pack fee covers storage retrieval, packing, and shipping. Standard non-media items: $3.06–$7.00+ depending on size/weight.

Storage Cost per Unit

= $0.30

Amazon charges per cubic foot per month. Jan–Sep: $0.78/cf; Oct–Dec: $2.40/cf. Spread across units sold.

PPC Advertising Cost

= $3.00

Pay-Per-Click spend as % of revenue. Competitive categories: 8–20%. Organic rank reduces this over time.

Return Cost (Blended)

= $0.93

When a buyer returns, Amazon refunds the buyer and you absorb the loss plus a return processing fee. Blended across all units sold.

Total Fees Per Unit

= $11.95

The full Amazon fee stack. Every fee is a fixed cost that makes raising your sale price more effective than cutting COGS.

Net Profit Per Unit

= $11.29

What you actually keep after Amazon takes its cut and you recover your investment.

Net Margin

= 0.4%

Healthy FBA margin: 20–30%+. Below 15% leaves little room for fee increases, returns spikes, or price competition.

ROI on Inventory

= 1.7%

ROI measures capital efficiency. Target 50%+ for FBA. Low ROI means slow inventory turns or too much working capital tied up.

Break-Even Sale Price

= $14.31

The minimum price at which you break even. Price cushion = sale price − break-even. Tight cushion = high sensitivity to fee changes.

Monthly Net Profit

= $1,693.92

Total monthly take-home after all fees, COGS, and advertising across your sales volume.

Annual ROI on Capital

= 20.1%

Annual return on inventory investment. Healthy target: 100%+ (double your money annually). Below 50% suggests the capital could work harder elsewhere.
