About GetShipMargin Tools
Why GetShipMargin Tools exists and how it helps ecommerce operators make clearer day-to-day decisions.
Last reviewed: August 31, 2026
Who we serve
GetShipMargin Tools is built for Amazon, Shopify, eBay, and Etsy sellers, DTC brands, 3PL teams, warehouse operators, and small ecommerce businesses.
Why it exists
Ecommerce operators often spread pricing, advertising, inventory, shipping, and document work across disconnected spreadsheets. GetShipMargin Tools turns common inputs into clear, repeatable decisions a small team can act on.
What you can do
Use free calculators for profit, pricing, advertising, inventory, landed cost, packaging, shipping, and marketplace fees, plus practical generators for common ecommerce documents. Core results are available without registration.
How calculations work
Final calculator outputs use deterministic, versioned formulas. Carrier-specific results require a current verified source. If a source has not been verified, the calculation is disabled rather than guessed.
Report an error
Send the page URL, the result you received, the result you expected, and an authoritative source through the contact or corrections page. Rule changes require review before publication.
