How do I calculate net profit per order with the Peptide Dropshipping Margin Calculator?

Subtract your Tier 1 ($397/mo), Tier 2 ($497/mo, 10% off wholesale), or Tier 3 ($697/mo, 25% off wholesale) unit cost plus the flat $15 California blind shipping fee (and optional +$2 custom box) from your retail order price.

How many monthly orders are required to break even on each B2B membership tier?

At an average multi-vial gross profit of $95 to $145 per order, most B2B storefronts break even on their monthly membership within their first 3 to 6 customer orders.

Chargebacks are modelled as full loss of revenue plus the chargeback fee — you lose the sale, the product and the fee. Refunds are modelled as loss of revenue and shipping, with product recovered.

How to read this

The number that surprises most resellers is the gap between gross margin and net. A $31 gross margin routinely lands near $18–$20 once processing, shipping, fulfillment, refunds and chargebacks are taken out — and the chargeback line does the most damage, because a chargeback costs you the revenue, the product, the shipping and a fee of $15–$100.

The sensitivity table matters because your processor discount rate is the input you have least control over and it changes when you switch acquirers or get repriced. Half a point sounds trivial and is not.

For the full picture on rates, reserves and what drives them, see the payment processing guide. For where wholesale cost comes from, see reseller margins.
