What we build
The first tool is an Etsy profit calculator for US sellers using Etsy.com, a US bank account, and USD. It supports order contribution profit, a Payment Account estimate, and target-price scenarios within documented boundaries.
How estimates are handled
Automated marketplace rules are versioned and tied to official source evidence where available. Unsupported or ambiguous scenarios fail closed instead of silently substituting zero or a nearby rule. Product conventions, including cent rounding, are disclosed separately from Etsy-confirmed behavior.
Privacy by design
Calculator arithmetic runs in the browser. MarginGauge does not require an Etsy account connection and is designed so analytics never receives calculator amounts, item details, state selections, coupons, or other financial inputs.
Independence
MarginGauge is an independent product and is not affiliated with, endorsed by, or sponsored by Etsy, Inc. Etsy is a trademark of Etsy, Inc.
