Based on the effect of monopoly on the economy, the deadweight loss that arises from a monopoly is a consequence of the fact that the monopoly's "price is higher than the socially-optimal price."
Deadweight Loss in Monopoly is a term that is used to describe the condition which occurs when a monopoly charges a price to consolidate its power above marginal cost. This implies that the price charged by the monopoly is higher than the socially-optimal price.
This, this situation drives a "wedge" between the costs born by the consumer and supplier leading to what is known as a deadweight loss.
