Digital Product Profit Calculator accuracy and testing

Formula source

• Gross revenue = selling price x units sold. Retained sales = units sold x (1 - refund rate). Net revenue = selling price x retained sales. Estimated profit = net revenue - percentage fees - fixed fees - variable costs - production cost - marketing cost.
