What is marginal revenue?
Marginal revenue is the additional revenue generated from selling one more unit of a good or service. Comparing it to marginal cost helps businesses decide the profit-maximizing level of output or pricing.
How this calculator works
Enter total revenue and quantity sold at two different sales levels. The calculator divides the change in total revenue by the change in quantity to find the average marginal revenue per additional unit over that range.
Marginal revenue can fall as more units are sold, particularly if a lower price is needed to sell additional volume. This tool is for general business and economics education purposes.
