The $781 billion estimate is the 2025 U.S. total cost for Alzheimer's disease and related dementias, disorders that damage memory and daily function, discussed in the National Institute on Aging's 2026 summit report. For family caregivers, the planning lesson is direct: budget beyond medical bills because most of the total reflects unpaid care, lost earnings, and quality-of-life loss.
The figure comes from the USC-led U.S. Cost of Dementia Project funded through an NIA cooperative agreement. About 5.6-6 million Americans lived with dementia in 2025, which helps explain why household effects add up so fast.

What the $781 billion covers
Only $232 billion, about 30%, is medical and long-term care. The remaining $549 billion reflects unpaid care, lost earnings, and quality-of-life loss, according to the USC Schaeffer Center in the 2025 cost analysis.
The National Institute on Aging places that total in context in the 2026 summit report, describing annual dementia costs approaching $781-800 billion including direct care and unpaid caregiving. That framing matters for families because a hospital bill shows only part of the burden.
Why families carry most of the cost
Family members and friends provide about 6.8 billion hours of unpaid dementia care each year. Valued at about $34.50 per paid home-care hour, that time is worth $233 billion.
The largest societal cost is reduced quality of life, estimated at $302 billion for people living with dementia and $6 billion for care partners in 2025. Lost pay adds another layer: caregivers forfeited about $8 billion in 2025 earnings.
What Medicare and Medicaid pay
Medicare paid $106 billion and Medicaid paid $58 billion toward medical and long-term care costs in 2025. Those payments come from the smaller medical-care share, not the larger unpaid-care share.
That split explains a common surprise. Doctor visits and nursing care may have coverage, while daily supervision, rides, meals, missed work hours, and reduced work schedules often do not. Families should track both types of spending from the start.
How to plan for the full cost
List weekly unpaid hours, time off work, travel, home help, supplies, and respite care. Assign the paid home-care rate to unpaid hours to see the hidden household contribution.
- Write down who provides each task and how many hours it takes.
- Estimate lost income from reduced hours, declined shifts, or delayed return to work.
- Review what Medicare and Medicaid pay for medical and long-term care versus daily support.
- Revisit the plan after diagnosis changes, hospital stays, or new behavior symptoms.
What the number still misses
Indirect costs such as long-term financial harm for caregivers and difficulty reentering the workforce remain poorly understood. Future models are expected to add legal, housing, and mental-health costs.
Newer work points higher: the 2026 $818 billion update reports $23 billion in forgone earnings plus $237 billion in unpaid-care value, according to the USC Schaeffer Center in the 2026 cost update. Treat $781 billion as a floor, not a ceiling, when planning savings and backup help.
