Amazon FBA, Etsy & Shopify Fee Comparison & Profit Calculator

Amazon & Etsy Profit Calculator 2026: Fees, Margins & Real Take-Home Per Sale

You sell a handmade candle for $24 on Etsy. Etsy takes the listing fee ($0.20), the transaction fee (6.5%), the payment processing (3% + $0.25), and if the buyer found you through an Etsy ad, another 12–15%. Suddenly your $24 sale nets ~$18.50 — before materials, labor, packaging, and shipping. Most sellers discover this math quarterly, when the numbers do not add up. A profit calculator shows the per-sale truth instantly: revenue minus every fee minus costs equals the number that actually matters.

Amazon's fee stack is taller. Referral fee (8–15% by category, 15% for most), FBA fulfillment fees ($3–$6+ per unit by size/weight), monthly professional plan ($39.99), plus optional advertising (TACOS 5–15% for most sellers). A $30 product on FBA: $4.50 referral + $4.50 fulfillment + $39.99/month amortized + materials + freight. Sellers targeting "30% margins" routinely land at 10–15% after the full stack — and that is before returns (Amazon's return rate in some categories exceeds 15%, and you eat the fulfillment both ways).

Etsy's stack is simpler but sneaky. The 6.5% transaction fee applies to the total including shipping charges you set — price shipping "free" and bake it in, or the fee eats your shipping margin too. Offsite Ads (12–15%) are mandatory once you cross $10k/year in sales, and you cannot opt out — factor it as a cost of scale. The $0.20 listing fee renews every 4 months or per quantity sold. None of these are dealbreakers; they are just math that must be in the spreadsheet before pricing, not discovered after.

Pricing strategy flows from the fee math. The 3× materials rule (price = 3× material cost) leaves room for fees, labor, and profit on most handmade goods — $8 in materials → $24 price. For Amazon private label: land cost (product + freight + duties) × 3–4× = viable retail, because the fee stack consumes ~35–45% of revenue. Never compete on price alone against sellers who do not know their costs — they are subsidizing your market education with their losses. Compete on differentiation, then price from math.

The hidden profit levers: shipping (negotiated carrier rates beat retail postage 20–40%; cubic pricing for small heavy items); packaging (polymailers over boxes where possible); returns reduction (accurate photos and sizing cut return rates dramatically — each avoided return saves the full fee stack); and tax (collect/remit correctly — marketplace facilitator laws mean Amazon/Etsy handle most sales tax, but income tax on profits is yours). The calculator models per-unit economics; your job is improving each line.
