market equilibrium & surplus
Controls
Presets
Where the downward demand curve crosses the upward supply curve, the market clears: that price and quantity are the equilibrium. Shifting either curve moves it. The shaded triangles are consumer and producer surplus — the total gains from trade. A per-unit tax lifts the supply curve, raising price, cutting quantity, and creating deadweight loss.
