Dropshipping Margin Calculator

Written out

Gross margin on a dropshipped product is (price − supplier cost − supplier shipping) ÷ price. Net margin subtracts payment fees, advertising and refunds as well.

The gap between the two is unusually wide in this model, because advertising is a variable cost per order rather than a fixed marketing budget.

Gross margin is what determines whether there is room to advertise at all, so it is the first number to establish.

Running the numbers

At $29.99 with $9.00 of landed supplier cost, gross margin is 70%. After the $1.17 payment fee it is 66%.

That 66% is what funds advertising, refunds and profit. At a $12 acquisition cost, 40% of revenue, and 7% for refunds, net margin is 19%.

Now the same product sold at $19.99 with the same costs: gross margin is 55%, and after payment fees 51%. The same $12 acquisition cost is now 60% of revenue, and net margin is under 4%.

A $10 price difference moves the business from viable to not, which is why dropshipping price points cluster where they do.

What gets missed

High gross margins in this model are necessary rather than generous. A 70% gross margin sounds excellent against retail benchmarks and is close to the minimum this cost structure requires.

Comparing dropshipping margins against conventional ecommerce margins misreads both. The dropshipper has no inventory cost and no fulfilment operation, and pays for that with an acquisition cost on every single order.

What to do next

Set a minimum gross margin threshold before sourcing rather than after. Most experienced operators will not touch a product below about 65% to 70% gross, because everything below that leaves too little to advertise with.

Then work backwards from the acquisition cost you can realistically achieve in the category, rather than forwards from the supplier price. If the category's cost per acquisition is $18, a product needs well over $18 of gross contribution before it is worth testing.

The three-times rule and where it comes from

The common guidance to sell at three times the landed cost is a rough expression of this arithmetic. At 3× landed, gross margin is 67%, almost exactly the threshold the cost structure requires.

It is not a pricing principle so much as a break-even constraint working backwards. A 2× multiple gives 50% gross margin, which leaves roughly $15 on a $30 product to cover a $12 acquisition cost, payment fees and refunds, and that does not work.

Where a product cannot support 3× at a price the market will pay, the honest conclusion is usually that it is not a dropshipping product. It may be a perfectly good product to sell with inventory, a brand and organic traffic, where the acquisition cost per order is a fraction of what cold paid traffic charges.

It is worth separating the margin on first orders from the margin on repeat ones. A repeat customer costs nothing to acquire, so their contribution is the full $17.72 rather than $5.72, three times better.

Any mechanism that produces repeat purchases therefore improves the blended margin dramatically, and in a model where every first order is bought, the second order is where the profit actually is.
