WASHINGTON, D.C. — In 2024, the cost of achieving a basic but secure American life increased by 4.4%, further stretching household budgets as wages fail to keep pace, according to new data released today by the Ludwig Institute for Shared Economic Prosperity (LISEP).
LISEP’s True Living Cost (TLC) Index and Minimal Quality of Life (MQL) Index show the price of both essential needs and upward mobility increased 4.4% in 2024. Although lower than the sharp spikes recorded in 2023 — 9.9% for TLC and 9% for MQL — the increases still outpaced the 3.9% growth in median weekly earnings for full-time workers, resulting in a 0.4% erosion of purchasing power.
Unlike the Consumer Price Index (CPI), which measures overall price changes across a basket of more than 80,000 goods and services, LISEP’s indices focus specifically on the costs that determine whether households can meet essential needs and build toward long-term stability. The TLC tracks the change in cost for the essential goods and services needed to maintain a basic standard of living, including housing, medical care, transportation, food, childcare, technology, and miscellaneous (e.g. clothing, personal care, and household items).
The MQL expands on the TLC to include the costs necessary for well-being, growth, and upward mobility, such as education savings, modest leisure, and other quality-of-life expenditures. Because these indices emphasize the expenses that weigh most heavily on working families, they often show stronger and more sustained cost pressures than headline inflation measures.
While the CPI has risen 77.2% from 2001 to 2024, the TLC has increased 106% and the MQL 108.1% over the same period. On an annual basis, both the TLC and MQL have grown at an average rate of 3.2% since 2001, compared to 2.5% for the CPI. Between 2019 and 2024 alone, the TLC increased 31.3%, averaging 5.6% annually, and the MQL increased 30.9%, or 5.5% annually.
The 2024 increase in the TLC was driven primarily by a 10.6% increase in housing and a 7.7% increase in childcare — the largest annual increase in childcare on record and the second-largest increase in housing since 2001. Grocery costs rose 2.9% in 2024, while medical costs increased 1.2% and transportation costs rose 1.3%. Although medical cost growth slowed significantly from 2023, healthcare remains the fastest-rising expense over the long term, increasing at an average annual rate of 4.9% since 2001.
“The pace of inflation has eased, but the affordability challenge hasn’t,” said LISEP Chairman Gene Ludwig. “After back-to-back years of sharp increases, the cost of essentials continues to rise faster than wages. And the gap between headline inflation and the real cost of living remains significant, especially for low- and middle-income Americans with little margin for error.”
The MQL, which expands beyond basic necessities to include the costs associated with well-being, opportunity, and long-term mobility, also rose 4.4% in 2024. The annual cost of maintaining a minimal quality of life now stands at $47,100 for a single adult; $121,100 for a couple with two children. In addition to the essentials tracked in the TLC, cost drivers within the MQL include: college savings (up 3.6%), eating out (up 7.1%), television subscriptions (up 12.7%), and weekend leisure (up 6.7%).
“Headline inflation numbers don’t fully capture what families experience,” Ludwig said. “When housing and childcare rise at double-digit or near-double-digit rates, those increases compound quickly. Slower inflation doesn’t undo the cumulative pressure households have absorbed over the past several years.”
