What Is a Good Profit Margin for Reselling?

The honest answer: margin alone cannot tell you if a flip was good.

By reva editorial teamUpdated 5 min read
Three numbers from one worked flip: 44% margin per item, 2 zł per day held, 31% net after hidden costs
Key takeaways
  • No universal margin target exists for reselling: public averages for EU resale are not credible, so set two personal lines from your own last twenty flips.
  • Margin per item must clear your fixed work: one floor number in zł, applied before you buy.
  • Margin per day is the fair way to compare a fast small flip with a slow big one — it prices the time your capital spends in stock.
  • Gross margin flatters; net margin after fees, shipping and supplies is the number that pays for the next buy.
  • A single percentage cannot say whether a flip was good — money, time and hidden costs decide that together.

The honest answer to what is a good profit margin for reselling: no single number exists. There are no trustworthy public averages for EU resale, and the same percentage can be excellent on one flip and pointless on another — margin alone says nothing about the money tied up, the time it sat, or what fees took. Below: the three numbers that do compare flips, and how to set your two personal targets from them.

One worked example runs through the whole page: a jacket bought for 100 zł, sold for 180 zł.

Why "50% margin" answers nothing on its own

A percentage hides its base. Fifty percent on a 40 zł lamp is 20 zł; fifty percent on a 600 zł console is 300 zł — different money, risk and work. The figure is slippery too: most sellers quoting a margin mean sale price minus item cost, before fees, shipping and supplies. So a stranger's margin tells you almost nothing — you need the base and the cost line.

Margin per item: your floor for taking a flip

margin per item = sale price − item cost − direct costs

For the jacket: 180 − 100 = 80 zł, or 44% of the sale price. The useful version is not the percentage but a floor in złoty. Every flip needs photos, a listing, messages and packing — roughly the same hour whether the item sells for 130 or 1,300. If your floor is "at least 30 zł net per item", an 80 zł flip passes twice over; a 12 zł flip fails before the percentage comes up.

Margin per day: comparing a fast flip with a slow one

margin per day = net margin ÷ days you held the item

The jacket held 40 days: 80 ÷ 40 = 2 zł per day. Second flip: a mug bought for 10 zł, sold for 30 zł — 20 zł margin in 5 days. That is 4 zł per day, twice the jacket's rate. Margin per day prices your capital's time — the only fair way to compare the mug with the jacket. It needs your own records of listed and sale dates; the metric behind it is days to sell.

One worked flip, three honest numbers
44%margin per item: 80 zł on a 180 zł salegross, before hidden costs
2 zł/daymargin per day: 80 zł over 40 days heldthe price of slow stock
31%net margin after 25 zł of fees, shipping and supplies55 zł — the number that buys stock
All three come from the same example flip. A flip is only 'good' against your own two target lines.Illustrative example, not market data

Margin after hidden costs: the honest version

net margin = sale price − item cost − fees − shipping you cover − supplies

Say the jacket's marketplace takes 12 zł in fees, you cover 9 zł of shipping, and packing materials cost 4 zł. Net margin: 80 − 25 = 55 zł, or 31% of the sale price instead of 44%. The full inventory of easy-to-forget costs is in hidden costs of reselling. Run your own numbers here:

What is a good profit margin for reselling, then

Your answer is two lines, from your own records rather than anyone's average:

  • A net floor per item — example: 30 zł and 25% of the sale price. Below it, walk away, whatever the category.
  • A target per day — example: 3 zł per day held. This is what makes small fast flips legitimate and slow big ones accountable.

Twenty recorded flips give you enough history to set both — the resale profit calculator and the habits in the resale profit guide get you there. Revisit the lines quarterly: raise them if your sourcing improved; if you set them from hope rather than history, reset them to true. What they protect in the background — money not stuck in stock — is the subject of reseller cash flow.

Frequently asked questions

What is a good profit margin for reselling?
No credible public average exists for EU resale platforms, so the honest benchmark is your own history. Set two lines from your last twenty flips: a net margin floor per item and a margin-per-day target. Example arithmetic only: a jacket bought at 100 zł and sold at 180 zł leaves 80 zł, 44% of the sale price — good or not depends on how long it held and what fees took.
How much profit should I make per item?
Enough to pay for the fixed work every flip needs — photos, listing, messages, packing — because that work costs roughly the same hour whether the item is cheap or dear. If you decide each flip must net at least 30 zł, an item that can only clear 12 zł is a pass unless it sells itself in days. Set the floor from what an hour of your reselling time needs to earn, and apply it before you buy.
Is a higher margin always better?
No. In the worked example, an 80 zł margin (44%) held for 40 days earns 2 zł per day. A 20 zł margin that exits in five days earns 4 zł per day — twice the rate — and frees the money for the next buy sooner. High-margin categories tend to be slower to sell, so the percentage and the time it takes must be read together; margin per day is the fairer comparison between two deals.
How do fees change my real margin?
Marketplace fees, shipping you cover and packing supplies come out before your profit does. In the example flip, 25 zł of those costs turn an 80 zł gross margin (44%) into 55 zł net (31% of the sale price). Compute the net version before you buy, at a price you can realistically achieve — and use your own tracked averages per platform, since fee rules differ by market.
