Relationship between marginal cost and marginal product. Marginal cost is the additional cost attributed to an additional unit produced. Marginal product is the increase in the total product due to an additional resource allocation. The marginal cost and marginal return have an inverse relationship and can almost be represented as mirror images of each other. The peak of the marginal product corresponds with the lowest point of the marginal cost. Thus as marginal product increases
