Core US Dropshipping Unit Economics Formulas (2026 Standard)
Unlike domestic e-commerce, cross-border US dropshipping operated via a US LLC + Stripe / Shopify Payments stack requires accounting for payment gateway fixed fees, dispute reserves, and foreign exchange (FX) repatriation spreads before calculating your allowable Customer Acquisition Cost (CPA).
CM_pre = AOV - (COGS + Ship_3PL + Fee_Stripe + Reserve_Refund + Fee_FX)
Represents the exact dollar pool remaining from an order before spending $1 on Meta or TikTok ads.
CPA_Breakeven = CM_pre ÷ (1 + Tax_AdAccount)
When billing ads to a US LLC (Tax_AdAccount = 0%), your Breakeven CPA equals your full Contribution Margin.
ROAS_Breakeven = Gross_AOV ÷ CPA_Breakeven
Any ad campaign operating above ROAS_Breakeven generates positive contribution profit per order.
WC_14 = (Orders_Daily × 14) × (COGS + Ship_3PL + CPA_Effective)
Calculates the liquid cash or credit limit required to fulfill orders while Stripe holds payouts during initial rolling reserves.

US LLC Dropshipping, Stripe Fees & Breakeven ROAS FAQ
1. How do you calculate Breakeven ROAS for US dropshipping? ↓
To calculate Breakeven ROAS in US dropshipping, first compute your Contribution Margin Before Ads: subtract Product COGS, 3PL US Line Shipping, Stripe/Shopify Payment Gateway Fees (2.9% + $0.30), Refund/Chargeback Allowance (3.5%), and Cross-Border FX Repatriation Fees (1.2%) from your Gross Order Value (AOV). Your Maximum Breakeven CPA equals this Contribution Margin divided by (1 + Ad Tax Rate). Finally, Breakeven ROAS = Gross AOV ÷ Breakeven CPA. On a $39.99 product with $12.50 landed COGS and $3.34 in gateway/refund/FX fees, your Contribution Margin is $24.15, giving a Breakeven ROAS of 1.66x.
2. What is a good profit margin for Shopify US dropshipping in 2026? ↓
In 2026, a healthy net profit margin for a scaled US Shopify dropshipping store operating via a US LLC and Stripe is between 15% and 24% of gross revenue after accounting for paid social Customer Acquisition Cost (CPA on Meta or TikTok Ads), landed 3PL shipping (YunExpress/CJ Dropshipping), payment processing fees, a 3.5% refund reserve, and monthly SaaS overheads.
3. How much working capital is needed for US LLC Stripe dropshipping? ↓
Starting US dropshipping properly with a US LLC and Stripe requires $1,400 to $2,200 (approx. ₹1.20 Lakhs to ₹1.85 Lakhs INR) in total capital. This covers three pillars: (1) $250–$300 for Wyoming/Delaware LLC formation, EIN, and Shopify setup; (2) $500–$750 for creative testing across 4 to 6 products on Meta/TikTok Ads; and (3) $600–$1,150 in 14-day working capital float to pay suppliers and ad platforms upfront while new Stripe/Shopify Payments accounts settle on a 7-to-14-day schedule.
4. What are Stripe and Shopify Payments fees for non-US residents with a US LLC? ↓
When a non-US resident forms a US LLC with an EIN and opens a US business bank account (Mercury or Relay), domestic US card processing rates apply on Shopify Payments and Stripe: 2.9% + $0.30 on Shopify Basic, 2.7% + $0.30 on Shopify Grow, and 2.5% + $0.30 on Shopify Advanced. If using a non-US Stripe account or accepting cross-border cards, an extra 1.5% fee applies (up to 4.4% + $0.30), plus a 0.8%–1.5% FX spread when transferring USD profits via Wise or Payoneer.
5. How does CPA affect net profit in Meta and TikTok Ads for dropshipping? ↓
Customer Acquisition Cost (CPA) is typically the largest expense in US dropshipping, consuming 35% to 50% of gross order revenue. Every $1.00 increase in CPA directly reduces net profit per order by $1.00 (or $1.18 if paying 18% unrecovered ad tax on a domestic ad account). Increasing Average Order Value (AOV) via quantity bundles or post-purchase upsells is the most reliable lever to absorb rising CPAs.
6. Why do international dropshippers use a US LLC Ad Account instead of a domestic ad account? ↓
Billing Meta or TikTok Ads to a domestic entity in countries like India, the UK, or the EU incurs 18% to 20% GST/VAT on top of ad spend. Billing ads directly to a US LLC with a US business card incurs 0% VAT/GST on ad spend, immediately preserving 6% to 8% of gross store revenue in cash flow.
