Thrift flipping rules of thumb
Many US resellers use a "3x rule": only buy if it'll sell for at least three times what you pay. Because eBay and Poshmark take a large share, a $5 item selling for $15 on Poshmark leaves you about $7 profit — the calculator shows exactly where your line is.
For low-priced items under $15, Poshmark's flat $2.95 fee takes a big bite. Bundling or selling on Depop can be better value.
