Frequently asked questions
What is marginal revenue?
Marginal revenue is the extra revenue from selling one more unit. If revenue rises $5,000 when 200 more units sell, marginal revenue is $25 per unit.
What is it used for in practice?
Firms maximise profit where marginal revenue equals marginal cost. Tracking it shows whether selling more is still adding to the bottom line.
