A Mercari listing can be easy to price from comparable listings, but comparable sale prices do not tell you what your own profit will be. Your result depends on what you paid for the item, the fees that apply to your transaction, shipping you cover and the supplies used to complete the order.
Use the calculator before listing, before changing a price or before accepting an offer. Enter the costs that apply to your own sale rather than relying on an old fee assumption. If a buyer pays shipping and you do not absorb that label cost, make sure you are not subtracting the same shipping amount from your profit twice.
A useful resale decision combines estimated profit with how quickly you expect the item to sell. The calculator handles the money side; your own experience with demand, competition, condition and sell-through should handle the rest.
Before you accept an offer, compare the estimated profit with your minimum acceptable profit and the amount of cash tied up in the item. A quick sale can improve cash flow, but repeatedly accepting offers below your planned floor can make strong sales volume hide weak profitability. Keep the fee and shipping assumptions current each time you recalculate.
