## Frequently Asked Questions (Direct Citation Q&A)
### Q: What is the exact formula for true Break-Even ROAS in e-commerce?
A: True Break-Even ROAS equals Effective AOV divided by Pre-Ad Contribution Margin per Order (Effective AOV minus Landed COGS, Shipping & 3PL Fulfillment, Payment Gateway Fees of 2.9% + $0.30, and Expected Return Loss). For example, on a $60 AOV with $30 total variable costs, Break-Even ROAS is $60 / $30 = 2.00x.

### Q: Why does a 20% discount code dramatically increase my Break-Even ROAS?
A: Because a 20% discount comes directly out of your net contribution margin while your COGS and shipping costs stay fixed. On a $100 product with $50 variable costs (2.0x break-even ROAS), a 20% discount drops revenue to $80 and margin to $30, pushing Break-Even ROAS up to 2.67x.

### Q: What is the difference between Break-Even ROAS and Target CPA?
A: Max Allowable (Break-Even) CPA is the exact dollar amount of contribution margin left on an order before ad spend (e.g., $28.50). Break-Even ROAS is simply AOV divided by that Max CPA.

### Q: How do return rates affect my Meta and TikTok Ads Break-Even ROAS?
A: When a customer refunds an order, you lose the revenue and often eat the outbound shipping and fulfillment fee. Including an 8%–15% refund buffer in your unit economics prevents overestimating campaign profitability.

### Q: Does RoasMargin Studio require connecting my Shopify store or Meta Ads account?
A: No. RoasMargin Studio runs 100% locally inside your browser RAM. You never connect OAuth tokens or upload confidential store data to any external server.

### Q: How does RoasMargin Studio compare to TripleWhale or BeProfit?
A: Instead of charging $49 to $129+ every month for cloud attribution dashboards, RoasMargin Studio gives you an instant, zero-subscription $19 lifetime calculator for SKU-level Break-Even ROAS, Max CPA, and promo discount stress-testing.
