Mercari vs eBay for Clothes Under $20: Which Platform Keeps You More Money?

The fee structures at a glance

The critical difference: eBay's 13.25% applies to item price plus shipping you charge. Mercari's 10% applies to item price only when the buyer pays shipping separately.

Head-to-head: $15 clothing item, buyer pays shipping

You sell a used t-shirt for $15. Buyer pays $5 shipping separately.

Mercari:

1. Selling fee: $15.00 × 10% = $1.50
2. Total fees: $1.50
3. Your take-home: $15.00 − $1.50 = $13.50

eBay:

1. Fee base: $15.00 item + $5.00 shipping = $20.00
2. Final-value fee: $20.00 × 13.25% = $2.65
3. Per-order fee: $0.30
4. Total fees: $2.95
5. Your take-home: $20.00 − $2.95 − $5.00 shipping pass-through = $12.05

Mercari wins by $1.45 on this sale. That's 10.7% more money in your pocket.

Head-to-head: $15 item, free shipping (you pay $5)

You list the same shirt at $15 with free shipping and eat the $5 postage.

Mercari:

1. Selling fee: $15.00 × 10% = $1.50
2. Your take-home after fees: $13.50
3. After $5 shipping out of pocket: $8.50

eBay:

1. Fee base: $15.00 (free shipping = $0 added)
2. Final-value fee: $15.00 × 13.25% = $1.99
3. Per-order fee: $0.30
4. Total fees: $2.29
5. After $5 shipping out of pocket: $15.00 − $2.29 − $5.00 = $7.71

Mercari wins by $0.79 even when you absorb shipping. The gap narrows because eBay's fee base drops (no shipping charged), but Mercari's flat 10% still beats 13.25% + $0.30.

The shipping trap that widens the gap

Here's where eBay sellers get burned on cheap clothes: eBay fees your shipping charge. Mercari doesn't (when buyer pays shipping separately).

The more you charge for shipping, the more eBay's fee grows while Mercari's stays fixed. Heavy items (jeans, boots, jackets) amplify this effect.

Full profit comparison: thrifted jeans

You buy Levi's at a thrift store for $4, list at $18, buyer pays $6 shipping.

Mercari:

1. Fee: $18 × 10% = $1.80
2. Take-home: $18.00 − $1.80 = $16.20
3. Profit after $4 cost: $12.20
4. Margin: 67.8%

eBay:

1. Fee base: $18 + $6 = $24
2. Fee: $24 × 13.25% + $0.30 = $3.48
3. Take-home: $24.00 − $3.48 − $6.00 shipping = $14.52
4. Profit after $4 cost: $10.52
5. Margin: 58.4%

You keep $1.68 more on Mercari for the same pair of jeans.

When eBay wins despite higher fees

Fees aren't everything. eBay has advantages that can offset the $0.79–$1.68 per-sale gap:

1. Buyer volume. eBay has roughly 130 million active buyers vs Mercari's ~20 million. For niche or vintage clothing, eBay's search traffic finds buyers faster.

2. Auction format. Rare band tees or vintage Levi's can fetch 2–3× fixed price via auction. A $15 fixed-price shirt might hit $35 at auction — even at 13.25% + $0.30, you net more.

3. International reach. eBay's Global Shipping Program handles customs and international logistics. Mercari is US-only for most sellers.

4. Promoted listings. eBay's ad platform can boost visibility on competitive items. The 2–5% ad fee stacks on top of 13.25%, but if it prevents a 20% price drop, it pays for itself.

Decision rule: If your item sells within 7 days on Mercari at full price, stay on Mercari. If it sits 30+ days, cross-post to eBay and accept the higher fee for the sale velocity.

Volume math: 50 items per month

You sell 50 clothing items averaging $15 each, buyer pays $5 shipping.

Over a year, that's $870 more in your pocket by defaulting to Mercari for sub-$20 clothing.

Cross-posting strategy

You don't have to pick one. Here's a practical workflow:

1. List on Mercari first (lower fees, faster listing flow).
2. Cross-post to eBay after 14 days if no sale.
3. Use the Marketplace Fee Comparison to set eBay price $1–2 higher to offset the fee gap.
4. Track which platform sells your inventory type faster — adjust default after 30 days of data.

Next steps

1. Run your average sale price through the Marketplace Fee Comparison to see the exact dollar gap.
2. Check your last 20 sales — calculate how much you'd have saved on Mercari's 10% flat fee.
3. For items over $50, re-run the math — eBay's percentage gap matters more in absolute dollars at higher prices.
4. Compare all three platforms (Mercari, eBay, Poshmark) with the Marketplace Fee Comparison before committing inventory to one app.
