Supply & Demand Market Simulator

Start at the original equilibrium E₀ (P₀, Q₀). Shift demand and/or supply, predict the new equilibrium, then reveal the outcome.

For this symmetric introductory simulator, slider values represent relative shift size. When both curves shift, the larger shift is treated as dominant; equal-sized opposing effects can leave price or quantity unchanged.
