Editorial Policy & Standards

At LWR Digital, we are committed to providing the most mathematically accurate calculators, guides, and analytical tools for independent creators, e-commerce brand owners, and digital entrepreneurs. Our content and tools are designed to remove financial ambiguity and help sellers optimize their pricing structures and scale their businesses profitably.

1. Accuracy First

E-commerce marketplace fees are constantly shifting. Our core editorial guideline is mathematical and data accuracy. All calculators on our platform (including Etsy, Amazon FBA, eBay, and Shopify calculators) are built using formulas derived directly from official developer API documentations and seller help center fee structures. We verify calculations using rigorous edge-case modeling before any calculator is deployed to production.

2. Data Verification & Sources

We do not rely on second-hand information or forum speculation. We source all calculator rates, percentages, and processing rules directly from the official source channels of the platforms (e.g., Etsy Help Center, Amazon Seller Central, eBay Fee Schedules, and Shopify Pricing). To review the exact source links used to compile our database, please visit our dedicated Data Sources Page.

3. Regular Review and Updates

Our dedicated development team monitors platform policy announcements daily. Whenever a marketplace (such as Etsy, Amazon, eBay, or Shopify) adjusts transaction percentages, processing base fees, or storage rate tiers, we update our database rules instantly. All tools show the "Last Updated" timestamp to ensure full transparency for our users. For details on our calculation formulas, visit our Methodology Page.

4. Independent & Unbiased Analysis

LWR Digital is a completely independent resource provider. We are not owned by, affiliated with, or sponsored by Etsy, Amazon, eBay, or Shopify. Our guides and tools are designed to reflect the real-world financial realities of online selling, highlighting both profit margins and the true cost of selling on these platforms without bias.

5. Editorial Integrity

Our editorial team does not accept paid placements to skew calculator metrics or recommend sub-optimal pricing strategies. If we review or suggest external tools, services, or SaaS solutions in our blog posts, we do so based on rigorous performance audits and seller feedback. Any sponsored content or advertisement slots are clearly labeled in compliance with FTC guidelines.
