Mercari Fee & Net Earnings Calculator

A flat selling fee, plus a fixed processing charge

A $32 sale with a 10% selling fee and $0.50 fixed processing fee carries $3.70 total platform fees ($3.20 + $0.50). After also subtracting $4.80 in shipping you paid and $9 item cost, net earnings come to $14.50 -- a 45.31% margin on the sold price.

Mercari's structure is simpler than eBay's tiered-by-category system: one flat percentage plus one small fixed fee, applied to every sale regardless of category, which makes this calculator's math a straightforward two-line formula rather than a lookup table.

Shipping ($4.80) is the largest single deduction after the item cost itself here -- for sellers using Mercari's prepaid label option, that shipping cost is fixed by weight and distance rather than negotiable, so it's worth weighing shipping cost against sale price before listing heavier items.

What's configurable here vs. fixed by Mercari

Uses a configurable selling fee. Promoted listings are extra. The 10% selling fee field is set to Mercari's commonly cited rate, but confirm the current rate on Mercari's seller help page before relying on it for pricing decisions, since platform fee structures change over time.

Promoted listing boosts (an optional visibility feature) are a separate cost not included in this net-earnings figure.

Local pickup or offline sales through Mercari can carry a different, often lower, fee structure than a standard shipped sale -- this model assumes a standard shipped transaction.

Comparing across resale platforms

The same item sold on Poshmark uses a tiered flat-fee-under-$15 structure instead of a flat percentage -- compare on the Poshmark Sales Profit Calculator.

For a higher-value item where eBay's category-specific rates might beat a flat percentage, check the eBay Profit & Final Value Fee Calculator too before choosing a platform.
