Poshmark Sales Profit Calculator

A flat fee below $15, a percentage above it

A $38 sale falls above Poshmark's $15 threshold, so the standard 20% commission applies rather than the flat $2.95 fee: $7.60 in fees. After subtracting an $11 item cost (with no shipping discount funded by the seller), net profit is $19.40 -- a 51.05% margin.

That $15 threshold creates a real pricing cliff: a $14.99 sale pays a flat $2.95 fee (19.7% effective rate), while a $15.01 sale pays 20% straight ($3.00) -- barely different in dollars at that exact boundary, but the effective fee rate structure flips from flat-fee to percentage-based right at $15.

Below the threshold, cheaper items actually carry a higher effective fee percentage: a $10 sale paying the flat $2.95 fee is a 29.5% effective rate, notably worse than the 20% rate on anything at or above $15.

The one line sellers often miss

Default commission is 20% on listings $15 and up, $2.95 under. Confirm current seller terms. Poshmark occasionally runs seller incentive programs or has updated its fee structure over time -- confirm the current rate on Poshmark's own seller terms page before pricing a large inventory around this default.

The shipDisc field lets you model a seller-funded shipping discount (a common promotional tactic) as a direct hit to net profit, separate from the platform commission itself.

Because the fee is commission-based rather than a fee-plus-fixed-cost structure like eBay's, there's no separate 'per-order' fee to add on top of the percentage shown here.

Deciding which platform to list on

For low-value items specifically, the flat $2.95 under-$15 fee can make Poshmark less attractive than a flat-percentage platform -- compare against the Mercari Fee & Net Earnings Calculator for the same low-priced item.

For higher-value items where eBay's category rate might undercut a flat 20%, the eBay Profit & Final Value Fee Calculator is worth checking side by side.
