# What is the difference between monopoly profit and monopoly rent?

I understand that monopoly profit is the return on capital (=profit) of the monopolist, which is larger than the normal profit in a competitive market. As monopoly rent I understand the income in excess of the factor cost (=rent) of the monopolist.
In this sense both would refer to the same thing. Is this correct?

$$\text{Producer Surplus}=\text{Profit}+\text{Fixed Cost}$$
