Marginal cost

A monopolist maximizes profit where marginal revenue equals marginal cost — then charges the price the demand curve allows. Because MR lies below demand, the monopoly produces less and charges more than a competitive market (where price equals MC). The red triangle is the deadweight loss: mutually beneficial trades that never happen.

Governing equation

M R = 100 - 2 Q = M C = 30 \Rightarrow Q_{m} = 35.0, P_{m} = $65.0

Reading this result: At MC = $30, the monopolist makes 35 units and charges $65 — a $35 markup over cost. That output is exactly half the competitive 70, and the shaded triangle (613) is the welfare lost to that restraint.

About this simulation

The full Monopoly Pricing tool models a game-theory standoff with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
