Understanding your **credit card processing fees** is vital for maintaining profitability in a consignment or resale shop. Most payment processors charge an interchange fee (a percentage of the transaction) plus a fixed fee (a small, flat amount per transaction). For example, a common rate might be 2.9% + $0.30. This calculator helps you quickly determine the **exact cost** of accepting cards for any sale amount, ensuring you accurately track your margins.
For consignment shops, which often operate on thinner margins due to revenue splits with consignors, minimizing payment processing costs is crucial. High fees can quickly erode the profit from lower-value transactions. Regularly using this calculator helps you compare quotes from different processors and understand the **effective rate**—the true percentage cost when both the percentage and fixed fees are accounted for. This insight allows you to negotiate better rates or adjust pricing strategies.
