About the Poshmark Offer Calculator

The Poshmark Offer Calculator is a free, fast, no-signup tool for resellers. From your list price and shipping choice it builds the full offer-to-likers ladder - the 10, 15, 20, and 25 percent-off prices - and shows what you actually keep on each after Poshmark's commission and any shipping you cover. Enter a target net instead and it works backward to the sale price that hits it, and tells you whether that price still satisfies the 10 percent minimum-discount rule. It runs entirely in your browser; nothing you type is sent anywhere.

Why a whole tool for one offer screen

Because the offer screen hides three interacting decisions behind a single tap: the discount, the shipping you fund, and a commission that switches from a flat fee to a percentage at the $15 mark. Doing that arithmetic in your head, in the moment, is how sellers end up netting far less than they expected, especially when a discount pushes an offer under $15 and the fee rule flips. A tool that lays out the whole ladder, applies the correct fee at each rung, and can run the math in reverse is genuinely more useful than a rule of thumb.

Freshness is the point

Every fee and shipping figure on this site lives in a single dated data module, and that date is shown on the page next to the numbers. The current figures were verified 2026-07-22. Poshmark has changed its fee and shipping structure before, sometimes on short notice, so when it moves we update the table and its date together. You can always see how current the answer you are reading is, and we would rather show you the date and let you judge than present a number with no provenance.

Who runs it

The Poshmark Offer Calculator is operated by Crossroads Technologies LLC, a small independent studio that builds focused, single-purpose web utilities. It is one of a small family of reseller math tools that share a look and a standard of care. There is no account system, no content farm, and no data collection inside the tool.

An important limit

This tool produces estimates for planning. It is not financial or tax advice, it is not affiliated with Poshmark, and it cannot see the full picture of your business. It applies Poshmark's general seller fee and shipping rules; the exact preset shipping discount you are offered can vary, and fees can change. For anything that matters, confirm the live figures on Poshmark before you send an offer. Reach us through the contact page.
