Great question. Most banks make money off fees they charge their customers. In 2017, Big Banks made $34 billion on overdraft fees alone. Good Money doesn’t charge you ridiculous fees. We make money off the interchange fee that Mastercard charges your merchant every time you use Good Money card. Then Mastercard gives us a portion of the interchange, at no expense to you. For example, if you buy groceries with your Good Money card, Mastercard will change your grocery store a few cents to process the transaction, then they give a percentage of those few cents.
