Affordability indexes usually publish percentages. We publish dollars first, because every component here is a real price — posted zone fares, Hudson-crossing tolls, the NYC congestion charge, garage rates, PSE&G-class utility tariffs, DOE/EIA energy data — and dollars are what people search for and what news stories quote. The income share is the badge, not the headline.
HUD income limits are the housing industry’s “AMI” — a median family income benchmarked to a 4-person household. It runs well above the median household figure (avg +47% in this metro vs the CBSA median household), which is why the same county can look affordable on one basis and stretched on another. HUD’s published 80% limit is capped and adjusted — in high-housing-cost areas it can exceed the area’s own median (Jersey City: $117,900 vs $110,100). “My income” recomputes the share client-side from the dollar figures (utility figures stay at the HUD-AMI bracket).

Dollar columns are the monthly cost of a representative household: the county’s median-priced home (tenure-weighted across renters and owners, ACS 2020–2024, utilities stripped out of the housing figure so nothing is counted twice), utility bills for the chosen income bracket (DOE LEAD 2022 trended to 2026 EIA prices, plus FCC/BLS water–broadband–cell figures), and the commute priced door-to-door at the county’s ACS workers-per-household (1.17–1.38) over 22 round-trips a month. Components are rounded to the dollar; totals are computed before rounding. Metro tier is the quintile among the 11 pilot counties at the product default (HUD AMI × utilities-full); 1 = most affordable fifth. The 48% line is the classic 30% housing envelope + 15% commute + 3% utilities, always evaluated on utilities-full.

What this index is
The 30% rule is missing two bills. Housing share is what listings show; the utilities and the commute are what move in with you. The True Lifestyle Cost Index adds all three from primary sources — TLC% = 12 × (H + U + C) ÷ income — and, unlike every percentage-only affordability index, publishes the underlying dollars on every page.
“TLC” has meant True Lifestyle Cost at TLCengine for over 13 years of MLS-integrated affordability analytics. This index rebuilds that heritage on TLCengine’s computed-commute engine: real posted fares, tolls, congestion charges, parking and fuel — not a spending model. Validated against the Center for Neighborhood Technology’s H+T® Index at r = 0.90 on the comparable construct (H+T® data © CNT, comparison only). Full methodology→

The True Lifestyle Cost Index is an independent affordability index published by TLCengine, computed from U.S. Census American Community Survey data, U.S. DOE and EIA energy data, HUD income limits, FCC and BLS consumer surveys, and TLCengine’s own door-to-door commute-cost engine.

Income limits. “HUD AMI” figures are HUD FY2026 area median family incomes and published income limits (huduser.gov); they are 4-person family benchmarks and differ from median household income.
