Poshmark's fee is simple — until it isn't
Poshmark's fee policy fits in two sentences: listing is free, and when an item sells the platform deducts a fee from the final order price — a flat $2.95 under $15, or 20% at $15 and above. There is no separate payment-processing charge, which makes it easier to reason about than most marketplaces. Two details still catch sellers out.
The first is the fee base. Poshmark charges on the item price after your discounts, and buyer-paid shipping sits outside that. This is the opposite of eBay and Mercari, which both charge their commission on the item price plus the shipping the buyer paid. A seller who cross-lists and assumes one rule applies everywhere will misprice on at least one platform.
The second is what the flat fee does to cheap items. Below $15, $2.95 comes off no matter how small the sale, so the effective rate rises as the price falls. At $14 the fee is 21.07% of the sale. At $10 it is 29.5%. At $5 it is 59% — you are handing over well over half the order. The headline "20%" is the best rate on the schedule, not the typical one for low-value inventory, which is why bundling cheap items into one order is standard practice.

The one step in the schedule
Because a flat fee gives way to a percentage at exactly $15, there is a single point where pricing a penny higher pays you less. At $14.99 you pay $2.95 and keep $12.04. At $15.00 you pay $3.00 and keep $12.00 — four cents worse. You have to reach roughly $15.06 before the percentage side beats what the flat side would have paid. It is small, but it is the only place in Poshmark's fee structure where the arithmetic rewards stopping just short.
How this calculator works
It takes the final order price, applies the flat fee or the 20% rate depending on which side of $15 the sale falls, and shows the effective rate so the flat-fee penalty is visible rather than buried. What is left is your payout. Then it subtracts your side: what you paid for the item, any shipping discount you chose to cover, and any other costs you entered.
Profit is the payout minus those costs. Margin is that profit as a share of the order; ROI is the same profit against what you had tied up in the item, which is the number that matters most when you source cheaply. Money is rounded to the cent, and the same function running in your browser is the one the unit tests assert against the worked examples below.
