What you get
Every entity page renders from the same build-time HUD dataset — deterministic results with no external calls at render time.
Fair Market Rents
Every Fair Market Rent HUD publishes for the entity's area — studio through four-bedroom — from the HUD FY2026 tables.
Income Limits
The full matrix: extremely low (30% AMI), very low (50%) and low (80%) limits for household sizes 1 through 8.
Area & Comparison
The HUD-defined area each entity is joined to, and how its 2BR Fair Market Rent ranks against other entities of the same geography type in its state.
National context
Purchasing-power context from the official BLS CPI-U series, stored once as a shared national asset. No federal tax withholding is calculated.

Documented sources, documented limits
HUD income limits, Fair Market Rents and Median Family Incomes are published values taken from the official HUD FY2026 tables and reproduced without adjustment. Values GovCalculator derives itself — rankings, medians and the FMR-to-income benchmark — are documented arithmetic over those published figures, not agency determinations.
The BLS CPI-U series is an official-normalized snapshot of the published BLS index. IRS Publication 15-T is cited as an official reference only — GovCalculator does not calculate federal tax withholding.
