eBay profit calculator — final value fees + promoted listings

Resellers often track gross margin (sale minus COGS). Real eBay profit is what you keep after final value fees (FVF), per-order fees, promoted listing ad rates, and shipping label cost.

eBay fee stack (US business sellers, 2026)

• Final value fee — typically 12.7–15.3% by category (most categories 13.6%)
• Per-order fee — $0.30 if item under $10, $0.40 if $10+
• Promoted listings — optional ad rate (often 2–12% of sale price)
• International fee — +1.65% on cross-border sales (if applicable)
• Your costs — COGS, outbound shipping label, packing, returns buffer

Private US sellers in most categories pay zero FVF since Oct 2024 — this guide targets business/reseller math.

Profit formula

Net profit = Sale price − COGS − Shipping label − FVF − Per-order fee − Promoted fee

FVF = (Item price + buyer shipping) × category % — eBay fees apply to the total sale amount, not item price alone.

Example: $50 resale item with 2% promoted

$50 sale · $20 COGS · $5 ship label · $6.80 FVF (13.6%) · $0.40 per-order · $1 promoted (2%) → net ≈ $16.80 (34%)

At 200 units/month that's $3,360 contribution — if you source at $22 COGS instead of $20, margin drops to ~$12.80 and reorder math changes fast.

Common margin mistakes

• Ignoring buyer-paid shipping in FVF base — free shipping doesn't reduce fees
• Category drift — trading cards (6% on $750+) vs books (15.3%) swing net by double digits
• Promoted listings creep — 8% ad rate on a thin-margin SKU can flip profit negative

When to upgrade from a calculator

At 1,000+ orders/month, Sellerboard ($19+/mo) syncs eBay, Amazon, and Shopify fees automatically. Until then, fast what-if reselling math prevents listing losers.
