The 4 Golden Rules of Dropshipping Unit Economics
Why 82% of beginners lose money on winning products — and the exact financial guardrails top 7-figure stores enforce before launching ads.
Minimum 3.5x — 4.5x Landed Markup
If your landed COGS + shipping is $12, never price below $42–$49. Anything under a 3.0x markup leaves zero room for paid customer acquisition on Meta or TikTok.
Keep Break-Even ROAS Below 1.75x
When your Break-Even ROAS is 1.55x, a standard 2.1x TikTok campaign prints 26% net profit. If Break-Even ROAS exceeds 2.2x, ad auction volatility will eat your margin.
Enforce Strict Max CPC Guardrails
Don't wait until spending $200 to kill a bad creative. Multiply your Max CPA by your store CVR to get your exact Max Kill CPC ceiling and cut losers after 1,500 impressions.
Acquire on Unit 1, Profit on Unit 2
You pay for the click only once. Getting just 20% of customers to buy a $25 bundle add-on adds $5.00 in pure contribution margin to every single order across your store.
