The $781 billion dementia economic estimate is the total U.S. cost of Alzheimer's disease and related dementias in 2025, calculated by the NIA-funded U.S. Cost of Dementia Project and later repeated in 2026 federal materials on dementia research progress.
Researchers at USC's Schaeffer Center built the figure from four parts — medical spending, unpaid family care, lost wages, and quality-of-life loss — and a newer 2026 study has already pushed the national number higher. For adult children managing a parent's dementia care, the number is less a headline than a map of where costs actually land. Part of it moves through Medicare and Medicaid. A much larger part moves through families, in hours and forgone income that no agency tracks or reimburses.

Where the $781 billion figure comes from
The estimate comes from the U.S. Cost of Dementia Project, a multi-year research effort based at the University of Southern California and funded through a cooperative agreement with the National Institute on Aging at the National Institutes of Health, with USC's Julie Zissimopoulos serving as contact principal investigator, according to the NIH RePORTER project record. The project published its first full accounting in a 2025 USC Schaeffer Center report, which set the U.S.
economic burden of Alzheimer's disease and related dementias at $781 billion in 2025 dollars. That figure covers roughly 5.6 million Americans living with dementia, including about 5 million people aged 65 and older, per the same report. The 2025 estimate is explicitly the first entry in a planned annual series, so there is not yet a multi-year trend line from this specific project — only a single-year snapshot and, as of 2026, one follow-up update.
How the $781 billion breaks down
The $781 billion splits into four categories, and the split matters more than the total. Direct medical and long-term care spending accounts for about $232 billion, or 30% of the total: Medicare pays $106 billion, Medicaid pays $58 billion, patients and families pay $52 billion out of pocket, and other payers — mostly private insurance — cover $16 billion, according to the Schaeffer Center report. Unpaid family caregivers supplied an estimated 6.8 billion hours of care in 2025, which the researchers valued at $233 billion — making uncompensated family labor roughly as costly as all medical and long-term-care spending combined, public and private.
On top of that, family members who cut back hours or left jobs to provide care lost an estimated $8.2 billion in wages, a category the report notes most earlier dementia-cost estimates left out entirely. The single largest slice is reduced quality of life: $302 billion attributed to people living with dementia and another $6 billion to their care partners, together about 39% of the total. In other words, the two largest components of the $781 billion — quality of life and unpaid care — are borne almost entirely by patients and families, not by any payer system.
Why the number already changed in 2026
A follow-up USC-led study published June 24, 2026 in Alzheimer's & Dementia raised the national estimate to $818 billion for 2026, according to USC's Mann School of Biomedical Engineering. That update breaks down as $320 billion in quality-of-life loss, $237 billion in unpaid care, and $222 billion in medical and long-term care spending.
The 2026 figure updates the 2025 estimate rather than confirming it — the same four-part structure, with each category rising. Readers who see both numbers in circulation should treat $818 billion as the more current figure and $781 billion as the baseline year it grew from, not two competing estimates of the same thing.
What the estimate does not capture
Both the $781 billion and $818 billion totals value unpaid caregiving and quality-of-life loss using economic modeling assumptions — imputed wage-equivalent rates — rather than actual transactions, per the Schaeffer Center's published methodology. That means roughly 70% of the total is not money that changed hands; no one invoiced a family $233 billion for care, and no insurer paid out $302 billion for lost quality of life. The figures describe the scale of the burden, not a bill anyone can submit for reimbursement.
This distinction matters for anyone trying to use the number to plan. The $222–232 billion in direct medical and long-term care spending is a real spending figure, tracked through claims and payments. The quality-of-life and unpaid-care components are estimates of value, built to make an otherwise invisible burden visible — useful for policy and research, but not a figure that translates into an insurance claim or a tax credit.
What this means for adult children providing care
Medicare and Medicaid together cover only about 70% of the medical and long-term-care slice of the total — the $222–232 billion category — leaving patients and families to absorb the remaining 30% out of pocket, according to the Mann School and Schaeffer Center reports. The $233–237 billion in unpaid family care sits entirely outside that public spending.
No federal program reimburses it; the report quantifies it, but nothing in Medicare or Medicaid pays it back. For an adult child weighing how much time, income, or savings to put toward a parent's care, this is the practical takeaway: the hours spent on caregiving and the wages given up to provide it are real, documented costs at a national scale, but they are costs the family carries alone. Confirming what Medicare or Medicaid will and will not cover for a specific parent's situation — before stepping back from paid work — is the one action this data points toward directly.
Frequently Asked Questions
Is $781 billion or $818 billion the correct current figure?
$818 billion is the more current figure, published in June 2026 as an update to the original 2025 estimate of $781 billion, per USC's Mann School of Biomedical Engineering.
Does the $781 billion figure include nursing home and home health costs?
Yes, those costs sit inside the $232 billion medical and long-term-care category, split among Medicare, Medicaid, out-of-pocket family spending, and private insurance, according to the Schaeffer Center report.
Can families claim reimbursement for the unpaid caregiving hours counted in the total?
No. The $233 billion unpaid-care figure and the quality-of-life estimates are modeled values, not actual payments, and no federal program reimburses them.
