Figures are computed on your device; nothing is sent anywhere.

Formula

১. revenue = sellingPrice × units ২. unitCost = productCost + shippingCost ৩. totalCost = unitCost × units + adSpend ৪. profit = revenue − totalCost ৫. margin = profit ÷ revenue × ১০০

How the calculation works

Revenue is the selling price times units, and the unit cost adds the product and shipping costs.

The total cost multiplies the unit cost by units and adds the ad spend, giving the profit after everything.

The margin is that profit as a share of revenue, which shows how much room there is for error.

Common mistakes

Leaving out the ad spend, which for many dropshipping stores is the largest single cost.
Forgetting return and refund rates, which quietly cut the real margin.

When to use it

Use it to check whether a dropshipping product clears a profit after ads.
It is not a supplier quote; it uses the costs you enter.

Worked example

100 units at 30, product 10, shipping 5 and 500 of ads give revenue 3000, profit 1000 and a 33.33% margin.

Revenue at break-even ৳3,000.00

Total cost ৳2,000.00

Profit ৳1,000.00

Margin per unit 33.33

Common questions

Are ads included?

Yes, total ad spend is subtracted, since it is a real cost of each sale.

What margin should I aim for?

Dropshippers often want 20 to 30%, but the safe figure depends on your return rate.
