American Dream Ledger: Lifetime Household Cost

## What this measures

The sum of eight components, each its own signal: a home bought with a 30-year mortgage, cars over an adult lifetime, raising two children, public college for both, health care for two adults, the savings needed for retirement, vacations and pets. Built only from public data and recomputed every month. Dollars, monthly.

## Why it matters

It puts the big costs of a middle-class life in one number that updates with prices and mortgage rates, and can be read against what a household earns over a working life.

## How to read it

Higher means the same life costs more. Compare it with the median household's lifetime income (a separate signal): when the cost runs ahead of income, the dream is getting harder to afford. The component signals show what moved.

## What it does not say

It is a ledger of typical costs, not a budget: averages and stated assumptions, not any one family. Weddings, maintenance, food and everyday living costs outside these components are not included. Each component's methodology lists its limits.

## How it is priced

Each month is priced in that month's dollars. Annual public figures (a BLS Consumer Expenditure Survey year, an NCES academic year, a CMS health-spending year) are the average for their own period: a month inside the period is the figure × the matching CPI-U index for the month ÷ its average over the period, and months after the newest published period carry that figure forward by the same index until the next edition replaces it. Nothing is projected forward and nothing is discounted: it is the price tag at today's prices. A month is written once its CPI and a full month of mortgage rates exist. October 2025 has no reading because BLS published no CPI for it.

## Assumptions

Assumptions used across the American Dream Ledger: an adult lifetime of 60 years (18 to 78, about the remaining period life expectancy at 18 in SSA's life tables); a working lifetime of 40 years (25 to 64); two adults and two children; a 30-year fixed mortgage with 20% down; four years of public in-state college per child; retirement of 20 years from 65 (about SSA's period life expectancy at 65, men and women averaged) at 70% of median household income. Weddings are left out: no public-domain source measures what a wedding costs.
