Data Sources & Methodology

Methodology & Data Sources — Updated for 2026

1. Overview of Our Analytical Framework

At TrueCostLiving, our goal is to deliver transparent, mathematically rigorous, and realistic living cost projections for 1,000+ American cities. We combine official U.S. federal and state governmental data sets with localized economic benchmarks to compute what households actually spend.

Unlike calculators that rely exclusively on self-reported crowdsourced questionnaires, our model incorporates statutory tax law, Department of Housing and Urban Development (HUD) benchmarks, Bureau of Labor Statistics (BLS) consumer expenditure data, and Department of Agriculture (USDA) dietary nutritional cost plans.

2. Primary Data Sources by Expense Category

Housing & Rent

Housing costs represent the largest expense for most households. We utilize:

  • U.S. Department of Housing and Urban Development (HUD): FY2025–2026 Fair Market Rents (FMR) evaluated at the 50th percentile for Studio, 1-Bedroom, and 2-Bedroom residential units by metropolitan statistical area (MSA) and county.
  • U.S. Census Bureau (ACS): American Community Survey 5-Year Estimates for local home values, homeowner vacancy, and property tax millage baselines.
Taxes & Net Take-Home Pay

Our salary after-tax computations reflect current statutory provisions:

  • Internal Revenue Service (IRS): 2026 Federal Income Tax Brackets, standard deductions (,000 single / ,000 married filing jointly estimated), and applicable phase-outs.
  • FICA (Social Security & Medicare): 6.20% Social Security tax applied up to the statutory wage base limit, and 1.45% Medicare tax (with additional 0.9% high-income surtax where applicable).
  • State Departments of Revenue: Individual state income tax brackets, local municipal earned-income taxes, and state-specific standard deductions.
Groceries & Food

Food expenditures are modeled using standardized nutritional baselines:

  • United States Department of Agriculture (USDA): Official Food Plans: Cost of Food at Home based on the Moderate-Cost Plan for individuals, couples, and children of varying ages.
  • Bureau of Labor Statistics (BLS): Consumer Price Index (CPI) for Food at Home adjustments by geographic region.
Transportation

Transit costs reflect real-world vehicle operation or public transit usage:

  • American Automobile Association (AAA): Your Driving Costs annual survey data for vehicle depreciation, maintenance, insurance, and financing.
  • Energy Information Administration (EIA): State-level retail gasoline prices and fuel excise tax schedules.
  • Metropolitan Transit Authorities: Monthly transit pass pricing for high-transit urban centers.
Healthcare & Utilities
  • Healthcare: BLS Consumer Expenditure Survey healthcare benchmarks combined with state health insurance marketplace silver-plan premium averages.
  • Utilities & Internet: Residential electric and natural gas rates from the EIA, municipal water/sewer averages, and nationwide broadband benchmark pricing.
Moving & Relocation Cost Estimates

Our moving calculator models realistic distance-based interstate and local moving ranges:

  • Weight & Volume Benchmarks: Calibrated inventory weight tiers (Studio: ~2,000 lbs, 1BR: ~3,500 lbs, 2BR: ~5,500 lbs, 3BR: ~8,000 lbs, 4+BR: ~11,000 lbs).
  • Distance & Labor Modeling: Great-circle driving distances, interstate fuel surcharges, loading/unloading hourly crew rates, and equipment wear factors.
  • Service Modalities: DIY truck rental, hybrid moving container (PODS-style), and full-service mover estimates.
Consumer Safety Advisory: TrueCostLiving provides estimates for informational planning only. When booking an interstate move, consumers should always independently verify that their chosen carrier has active USDOT and FMCSA operating authority by searching the official federal registry at safer.fmcsa.dot.gov.
