Why Most Resellers Don't Know Their Real Profit


Here's a hard truth: most resellers think</strong> they're making money, but they're not actually sure. They see money coming in, but between platform fees, payment processing, shipping, and the cost of the item — the real profit is a mystery.


Let's fix that.


The Real Profit Formula


Your actual profit on any sale is:


Profit = Sale Price - Platform Fees - Payment Fees - Shipping Cost - Item Cost</strong>


Simple, right? But the devil is in the details.




Breaking Down the Fees


Platform Fees by Marketplace



Payment Processing Fees


If the platform doesn't include payment processing:

  • PayPal: ~2.9% + £0.30
  • Stripe: ~2.9% + £0.20
  • Depop Payments: ~2.9% + £0.30

  • Don't Forget Shipping


    If you offer "free shipping," you're paying for it</strong>. Factor it in:

  • Royal Mail 2nd Class Small Parcel: ~£3.20
  • Royal Mail 1st Class Small Parcel: ~£4.20
  • Evri/Hermes: ~£2.90



  • Real Example: £20 eBay Sale


    Let's calculate profit on a £20 item sold on eBay:


  • Sale price: £20.00
  • eBay fee (12.8%): -£2.56
  • Shipping (2nd class): -£3.20
  • Item cost (charity shop find): -£3.00

  • Real profit: £11.24</strong>


    That's a 56% margin</strong> — not bad! But notice how different that is from just seeing "£20" in your account.
