Lorenz Curve & Gini Coefficient — Progressive vs Flat Tax Simulator

Generate a population income distribution, apply progressive, flat or regressive taxation with a flat redistributed benefit, and watch the Lorenz curve bend toward equality while the Gini coefficient drops live.

Economics & Social Systems3DModerate60 FPS

Generate a population's pre-tax income distribution, choose a tax structure — progressive, flat or regressive — and watch the live Lorenz curve compare pre-tax and post-tax-and-transfer income shares against the perfect-equality diagonal, with a running Gini coefficient for both.

⚙ Under the hood

Generate a population income distribution and apply progressive, flat or regressive taxation with an equal flat-benefit redistribution. Watch the live Lorenz curve bend toward the equality diagonal and the Gini coefficient drop for progressive tax, while flat or regressive taxes leave the curve nearly as bowed.
