The core equation (Max PITI = min(GrossMo × 0.28, GrossMo × 0.36 - MonthlyDebt); Max Price = MaxLoan + DownPayment) computes exact pre-tax nominal figures using double-precision floating-point math, calibrated against Federal Reserve H.15 Selected Interest Rates, CFPB Regulation Z (Truth in Lending Appendix J), IRS Publication 590 & SEC Investor.gov Compounding Methodology. To model after-tax or inflation-adjusted real returns, reduce the rate input by your marginal tax or CPI rate.
