What is a good profit margin for reselling?

Above 50% is a strong flip. Between 30% and 50% is average but acceptable. Below 30% is generally too thin for most resellers — the time and effort rarely justify it unless the item moves quickly.

Do all categories have the same profit margins?

No. Shoes, electronics, and collectibles often carry higher margins because demand is strong and prices are predictable. Clothing and home goods can be more variable. Category and condition both affect how much markup the market will support.

Why does margin matter more than selling price?

A high selling price means nothing if fees and costs eat the profit. A $100 item that costs $80 to source and $15 in fees leaves you $5. A $20 item sourced for $2 with $3 in fees returns $15. Margin is what you actually keep.

How This Calculator Works

Two simple formulas. Enter your numbers and the calculator does the rest.

Net Profit selling price − item cost − fees

Profit Margin (net profit ÷ selling price) × 100

Margin above 50% is a strong flip. Between 30–50% is average. Below 30% is thin — worth asking whether the time and effort are worth it.

Why Profit Margin Matters

Margin is what you actually keep. A high selling price means nothing if fees and cost eat the profit. Knowing your margin tells you:

Whether the flip is worth your time at this price
How much room you have to negotiate on the buy price
Whether you should source similar items again
Whether marketplace fees make the sale unprofitable at this price
What selling price you need to hit your target margin

Example Profit Calculations

$5 thrifted shirt sold for $25

Item cost: $5 · Fees: $4 · Net profit: $16
Margin: 64% — Excellent return on a low-cost source. This is what a strong resale flip looks like.

Strong flip — 64% margin

$20 shoes sold for $40

Item cost: $20 · Fees: $6 · Net profit: $14
Margin: 35% — Acceptable but not exceptional. Worth listing if the item moves quickly; weigh time cost otherwise.

Average — 35% margin

$15 electronics sold for $30

Item cost: $15 · Fees: $8 · Net profit: $7
Margin: 23% — Too thin for most resellers. Consider a higher price, a lower-fee marketplace, or skip the item entirely.

Thin — 23% margin

Common Profit Mistakes

Forgetting to include shipping costs. If you offer free shipping, the label cost comes directly out of your margin.
Ignoring marketplace fees. A $40 sale on Poshmark leaves you $32 after their 20% — your true profit is $8 less than it looks.
Pricing based on retail tags instead of what items actually list for on the resale market. Retail price and resale value are often far apart.
Underestimating how condition affects price. An item in fair condition may need to be priced 30–40% below good condition to move.
Overvaluing low-demand categories. Some items look high-value but sit for weeks — factor in the cost of your time and storage.
Not comparing net profit across marketplaces. The same item might net $5 more on one platform just by switching channels.
