How this IBKR valuation is built
The model projects ten years of Interactive Brokers Group Inc's free cash flow to the firm and discounts each year at its own cost of capital. Rather than assuming today's growth and margins persist forever, a moat-scoring step — weighing Interactive Brokers Group Inc's ROIC-versus-WACC spread, gross-margin trend, and reinvestment efficiency — decides how many years the business holds its edge before its economics mean-revert toward the Damodaran NYU benchmarks for its industry.
WACC is rebuilt each year from an unlevered-then-relevered beta and the company's evolving capital structure; terminal value uses the Gordon growth model with a reinvestment rate tied to the return earned on new capital (goodwill stripped out to reflect operating efficiency). Every assumption — growth, margins, tax, leverage, convergence timing — is editable, and running the full interactive model adds a 10,000-draw Monte Carlo simulation and WACC-versus-terminal-growth sensitivity heatmaps.
