Dropshipping Margin Calculator

Dropshipping margins are notoriously thin, and many new dropshippers discover they are actually losing money on every order once all costs are properly accounted for. The supplier cost and shipping are obvious, but payment processing fees, platform subscription costs, and advertising spend per order often push the real margin below zero. This calculator reveals the complete picture.

The typical dropshipping cost stack includes supplier product cost (often 30 to 50% of selling price), supplier shipping to customer (highly variable depending on origin country and speed), payment processing (2.9% + $0.30 for most processors), and advertising cost per acquisition. On a $40 product with a $12 supplier cost, $4 shipping, $1.46 processing, and $12 in ad cost, your actual profit is $10.53 per order — a 26% margin that feels healthy until you consider refund rates, chargebacks, and customer service costs.

The breakeven ROAS figure is particularly critical for dropshippers because margins are tight. If your margin after all costs except ads is $22.53, and you spend $12 on ads to generate a $40 sale, your ROAS is 3.33x. Your breakeven ROAS is $40 divided by $22.53 = 1.78x. Anything below that loses money.

To improve dropshipping profitability, focus on increasing AOV through bundles and upsells (your supplier cost barely changes but revenue goes up significantly), negotiating better supplier pricing at higher volumes, switching to faster but cost-effective shipping methods that reduce refund rates, and continuously testing ad creatives to lower CPA. The most successful dropshippers eventually transition to holding inventory for their proven winners, which dramatically improves margins and shipping speed.
