Scope and definitions
This guide owns the informational intent; linked calculator pages continue to own interactive calculator intent.
The guide supports Poshmark Fee Calculator. Keep the numerator, denominator, cost categories, fee base, and time period consistent from the first input through the final comparison.
Calculation method
| Step | Calculation or rule |
|---|---|
| 1 | if final_order_price < $15: seller_fee = $2.95 else: seller_fee = 20% × final_order_price seller_earnings = final_order_price - seller_fee - seller_paid_shipping_discount |
Formula / rule
if final_order_price < $15: seller_fee = $2.95
else: seller_fee = 20% × final_order_price
seller_earnings = final_order_price - seller_fee - seller_paid_shipping_discount
Worked example
At a $50 final order price with no seller shipping discount, seller fee = $10 and seller earnings = $40, an effective marketplace fee of 20% before other business costs.
Practical reference
Record the relevant scenario fields together before calculating. The implementation brief calls for these comparison fields: Component, Amount. Using one record prevents values from different periods or scopes from being mixed.
