Two rules cover everything
Poshmark’s fee structure is the simplest on this site: sell for $15 or less and Poshmark takes a flat $2.95; sell above $15 and it takes 20% of the sale price. That is the entire schedule — no per-order fees, no store tiers, no payment-processing line (it is inside the 20%), no category exceptions. On the default $24 sale: $4.80 fee, net after a $6 cost is $13.20 — a 55% margin. The simplicity is a genuine feature: pricing is one multiplication, and the calculator exists mostly to keep the cliff discipline (below) and the shipping-discount honesty (further below) from quietly eroding it.
The $16-22 trap: where a higher price nets less
The flat-to-20% cliff creates the strangest pricing incentive in resale. A $15 sale nets you $12.05; a $16 sale nets $12.80 — fine. But look at the margin rate, not the dollars: at $15 your fee is 19.7% of revenue, at $24 it is exactly 20%, at $40 it is 20% — smooth. The trap is subtler than “higher price nets less” (it never does); it is that items priced $16-22 sit in the worst of both worlds — full 20% fee on a price too low to carry it. The 20% regime needs prices that can afford it: the practical guidance is to price into the $25+ band whenever the item can carry it (where 20% is 5+ real dollars and worth the platform’s buyer traffic), and to treat sub-$15 listings as volume plays where the flat $2.95 is genuinely cheap — a $10 sale nets $7.05, a 70.5% margin that no percentage-based platform can touch at that price.
Shipping discounts are money out of your pocket
Poshmark’s shipping promos — “discounted shipping” where the seller funds part of the buyer’s label — show up as marketing features and behave like fees. Funding $4 of a buyer’s shipping on the default $24 sale drops net from $13.20 to $9.20: you just paid a 16.7% surcharge for the promo badge. This is not always wrong — funded shipping on a stale listing that needs velocity can be the cheapest marketing you buy — but it must be a decision, not a default toggle. The calculator’s shipping-discount field exists so the promo cost lands in the same column as the fee: if the discounted net falls below your floor, the listing price needs to rise or the promo needs to die.
A worked example: the boutique-loop bundle
Thrifted dress: $8 cost. You list at $28. Sale: 20% fee $5.60, net before costs $22.40, after cost $14.40 — 51% margin. Now the actual play most successful closets run: offer “$15 item + $4.99 shipping” during a shipping-promo window. The $15 sale takes the flat $2.95, nets $12.05 before cost, $4.05 after the $8 cost — worse per unit, but if the promo moves the dress in three days instead of three months, the cash conversion and closet-position gain often beats the 28-dollar sit-and-hope. Run both through the calculator: the difference is $10.35 of gross net per unit. Bundle that decision across 200 listings and the flat-rate regime becomes a pricing strategy, not a quirk.
How Poshmark compares in 2026
At 20%, Poshmark is the most expensive mainstream structure for items over $15 — eBay’s 13.25% + $0.40 crosses 20% only below ~$4 sale prices, and Mercari/Depop now take 0% commission from sellers. What the 20% buys: a social closet experience with a buyer base that expects curation, shipping labels handled end-to-end at a flat buyer rate, and zero fee-structure anxiety. The rational division of labor most full-time resellers land on: move sub-$15 and mid-tier fashion on Poshmark where the flat fee wins the bottom and the audience pays the top, push $60+ items to eBay or Grailed where percentage economics favor them, and keep Mercari as the fee-free overflow. The calculators on this site exist precisely so that mix is arithmetic, not superstition.
