The direct answer
Home care becomes more expensive than assisted living when paid care reaches approximately 40 hours per week — though the exact crossover point varies significantly by state. In Ohio, the crossover occurs at approximately 41 hours per week. In South Dakota it arrives as early as 26 hours. In Hawaii, where assisted living costs are unusually high relative to home care rates, it doesn't occur until nearly 68 hours per week.
The difference is driven entirely by your state's hourly home care rate relative to its assisted living monthly median — two numbers that vary by as much as 300% across the country.
If a family member currently needs — or is approaching — 40 hours of paid care per week, the financial case for staying home may already be gone.

What is the 40-hour rule in long-term care?
The 40-hour rule is a widely cited rule of thumb in long-term care planning: when a person needs approximately 40 or more hours of paid home care per week, the monthly cost of that care typically equals or exceeds the monthly cost of assisted living in the same state.
The logic is straightforward. At the national median home care rate of $35 per hour in 2025, 40 hours per week costs approximately $6,062 per month — nearly identical to the national median assisted living rate of $6,200 per month. At that point, assisted living offers something home care does not: 24-hour staffing, meals, housekeeping, and social programming, all bundled into that same monthly figure.
The rule of thumb holds broadly but masks significant variation. The crossover point is not 40 hours everywhere. It is a calculation — and the inputs to that calculation differ by state, by housing situation, and by individual circumstance.
How the crossover point is calculated
The simple calculation
The basic crossover formula divides the assisted living monthly median by the weekly home care rate:
Crossover threshold (hours/week) = Assisted Living Monthly Median ÷ (Hourly Rate × 4.33)
For Ohio in 2025:
- Assisted living median: $6,103/month
- Home care rate: $34/hour
- Crossover threshold: $6,103 ÷ ($34 × 4.33) = 41.5 hours/week
For South Dakota in 2025:
- Assisted living median: $4,900/month
- Home care rate: $44/hour
- Crossover threshold: $4,900 ÷ ($44 × 4.33) = 25.7 hours/week
For Massachusetts in 2025:
- Assisted living median: $9,600/month
- Home care rate: $40/hour
- Crossover threshold: $9,600 ÷ ($40 × 4.33) = 55.4 hours/week
The difference between South Dakota and Massachusetts is nearly 30 hours per week — the equivalent of a full-time caregiver shift. A family in Sioux Falls and a family in Boston face entirely different financial timelines even if the care needs are identical.
The corrected calculation — why housing costs matter
The simple calculation overstates how quickly home care becomes more expensive. It compares the full cost of assisted living — which bundles housing — against home care alone, ignoring the fact that a person aging in place is already paying for housing separately.
A more accurate comparison asks: what does home care cost versus the care component of assisted living, since housing costs exist on both sides of the equation?
Corrected crossover threshold = (AL Monthly Median − Monthly Housing Cost) ÷ (Hourly Rate × 4.33)
For a family in Ohio paying $1,750/month in housing costs:
- Effective AL care cost: $6,103 − $1,750 = $4,353
- Corrected crossover threshold: $4,353 ÷ ($34 × 4.33) = 29.6 hours/week
For the same Ohio family who owns their home free and clear:
- Effective AL care cost: $6,103 − $0 = $6,103
- Corrected crossover threshold: $6,103 ÷ ($34 × 4.33) = 41.5 hours/week
The difference is 12 hours per week — entirely determined by housing cost. Whether a family rents, carries a mortgage, or owns free and clear changes when the financial case for a housing transition actually arrives. This is why two families in the same state with the same care needs can reach completely different conclusions from the same crossover calculation.

What the crossover point looks like in your state
Care costs vary significantly by state and are updated annually in LTCareNav's state care cost database — which reflects the CareScout Cost of Care Survey, the longest-running cost of care study in the United States.
To illustrate the range, here are five representative states across the cost spectrum:
South Dakota
Home care rate: $44/hour | AL median: $4,900/month | Simple crossover: 26 hours/week
Among the earliest crossover points in the country, driven by high home care rates relative to a low AL median.
Ohio
Home care rate: $34/hour | AL median: $6,103/month | Simple crossover: 41 hours/week
Close to the national average crossover, representing a broadly typical Midwestern market.
Texas
Home care rate: $30/hour | AL median: $5,666/month | Simple crossover: 43 hours/week
A large state with regional variation — major metros like Dallas and Houston trend above the state median.
California
Home care rate: $40/hour | AL median: $7,000/month | Simple crossover: 40 hours/week
Higher costs on both sides produce a crossover near the national average despite significantly elevated absolute figures.
Hawaii
Home care rate: $41/hour | AL median: $12,096/month | Simple crossover: 68 hours/week
The highest assisted living costs in the country mean home care stays financially competitive far longer than in any other state.
These figures reflect 2025 CareScout data via LTCareNav's state care cost database. Costs change annually. For current figures in your state, see your state's complete cost guide.
What shifts the crossover point in your favor — and what doesn't
Factors that push the crossover later (home care stays cheaper longer)
High assisted living costs in your state. In Connecticut, Hawaii, Massachusetts, and Alaska, assisted living medians exceed $9,000/month. Home care stays financially competitive well past 40 hours in these states — sometimes to 55–68 hours per week.
Owning your home free and clear. When housing costs are zero, the full AL monthly rate needs to be offset by home care costs. A family in Ohio who owns free and clear doesn't reach cost parity until approximately 41 hours — versus approximately 30 hours for a family paying $1,750/month in housing costs.
VA Aid and Attendance benefit. For eligible veterans and surviving spouses, Aid and Attendance pays up to $1,194/month toward home care costs. This effectively reduces the family's net home care cost, pushing the crossover point later. Most eligible families are not aware this benefit applies to home care. See if you qualify →
Medicaid home and community-based services. In states with robust HCBS waiver programs, Medicaid can pay for a significant portion of home care hours for those who qualify financially and functionally. This dramatically changes the financial picture for eligible families. See what your state covers →
Informal family caregiving. When a family member provides unpaid care alongside paid hours, the effective cost of home care is lower than the paid-hours calculation alone suggests. A family supplementing 15 hours of paid care with 15 hours of unpaid family care is not equivalent to a family paying for 30 hours. The crossover is calculated on paid hours — informal care extends the viability of aging in place, but only as long as the caregiver can sustain it.
Factors that push the crossover earlier (assisted living becomes cheaper sooner)
Low assisted living costs in your state. South Dakota ($4,900/month), North Dakota ($4,729/month), and Alabama ($4,425/month) have among the lowest AL medians in the country. In these states, the crossover arrives meaningfully earlier than the 40-hour national average — roughly 26 hours in South Dakota, 32 hours in North Dakota, and 38 hours in Alabama.
High home care rates. States with high minimum wages — California, Washington, Minnesota, Colorado, Maine — have correspondingly high home care rates of $40–$45/hour. Home care at these rates reaches AL cost parity faster than home care at $25–$30/hour.
Mortgage or rent payments. Families carrying significant housing costs see their corrected crossover threshold drop meaningfully. A family paying $2,500/month in rent in Ohio reaches cost parity at approximately 24 hours of paid care per week — not 41.
Caregiver sustainability. The crossover calculation assumes the informal family caregiver arrangement continues indefinitely. When it doesn't — and caregiver burnout is the most common reason home care arrangements break down unexpectedly — the effective cost of home care rises suddenly and significantly. The corrected crossover accounting for this risk is almost always earlier than families expect.
How to know where your family stands right now
The crossover threshold is a planning tool, not a verdict. Three questions help locate your family on the spectrum:
1. How many hours of paid care are currently provided per week?
Add up all paid caregiver hours — aide, companion, ongoing skilled nursing. Do not include family caregiver hours. The crossover calculation is based on paid hours only.
2. How fast are care needs increasing?
A family at 20 hours whose needs have doubled in six months is in a fundamentally different position than a family at 20 hours who has been stable for two years. The crossover threshold is static — the trajectory toward it is not. Direction of travel matters as much as current position.
3. How sustainable is the current arrangement?
If the informal caregiver is managing but finding it difficult — or if the home environment is becoming harder to navigate safely — the effective crossover may already be closer than the calculation suggests. An honest assessment of caregiver sustainability is as important as the hours count.
What the crossover point does not tell you
The financial crossover is one input into a housing decision — not the whole decision. Several factors legitimately justify staying home past the financial crossover point:
Strong preference for home. Familiarity, routine, and autonomy matter — especially when cognitive changes are a factor. The financial case for a transition does not override a person's clearly expressed wishes.
End-of-life care preferences. Many individuals have strong preferences about where care is received at the end of life. These preferences deserve significant weight in the housing decision.
A short remaining timeline. When life expectancy is limited, the long-term financial calculation carries less weight. Stability and comfort appropriately take precedence.
Exceptional informal care. A family with a capable, willing, and genuinely sustainable family caregiver providing significant hours may find that aging in place remains the right choice well past the financial crossover.
The crossover point answers one question: when does the financial case for a housing transition arrive? It does not answer whether a transition is right for a specific person. That answer requires the full picture — clinical, financial, relational, and deeply personal.
The costs most families overlook on both sides
What home care costs that families rarely budget for
Home modifications. Grab bars, ramp installations, walk-in shower conversions, and stair lifts typically run $8,000–$16,000 depending on state. These are one-time costs that rarely appear in home care budget calculations but directly affect the true cost of aging in place.
Coordination burden. At 30+ hours of paid care per week, managing a home care schedule — coordinating with multiple agencies, handling no-shows, managing caregiver transitions — becomes a significant unpaid job for family members. The time cost is real even when it doesn't appear in the calculation.
Emergency coverage gaps. When a caregiver doesn't show up, someone fills that gap. Usually a family member, usually without notice. The cost is invisible in the crossover calculation but very real in practice.
What assisted living costs that families rarely budget for
Level-of-care tiering fees. $300–$1,500/month added as needs increase. Not included in the base rate quoted during initial conversations or tours. This is the single most financially significant hidden cost in assisted living.
Move-in fees. Typically $1,000–$5,000, non-refundable, due before move-in. Almost never mentioned until the contract stage.
Annual rate increases. Assisted living rates increase an average of 4–6% annually. A rate that works today may not work in three years — and tiering fees compound on top of the base rate increase as care needs grow.
The national benchmark — how your crossover compares
The national average crossover point — using the simple calculation — is approximately 41 hours per week. This is based on the 2025 national median home care rate of $35/hour and assisted living median of $6,200/month.
States where the crossover arrives significantly earlier than the national average — South Dakota, North Dakota, Wyoming, Idaho, Iowa, Minnesota — are typically states where assisted living costs are low relative to home care rates, often reflecting high minimum wages alongside relatively affordable care communities.
States where the crossover arrives significantly later — Hawaii, Connecticut, Massachusetts, Alaska, Delaware — are states where assisted living is disproportionately expensive, often in high cost-of-living markets.
Your state's crossover relative to the national average is a useful planning benchmark. If your state's crossover is 30 hours and you are currently at 25 hours of paid care, you are close. If your state's crossover is 55 hours and you are at 25 hours, you have meaningful runway — though direction of travel still matters.
The questions that matter when you're near the crossover
When paid care hours are approaching or above the crossover threshold, these are the questions worth getting answers to:
For families evaluating assisted living:
- What is the base rate and what triggers a level-of-care increase?
- Do you accept Medicaid, and at what point in the process?
- What is your current availability and waitlist situation?

For families deciding to stay home longer:
- Is the current caregiver arrangement genuinely sustainable for 12+ more months?
- What is the plan if the primary family caregiver becomes unavailable?
- What home modifications would extend the safety and viability of the current arrangement?

Definitions
- Home care
- Non-medical in-home support with activities of daily living — bathing, dressing, toileting, meals, and companionship. Provided by a home care aide. Distinct from home health care, which is Medicare-covered skilled nursing or therapy.
- Assisted living
- A residential care setting providing 24-hour staffing, meals, housekeeping, and personal care support. Not a nursing home — most assisted living communities are not equipped for complex ongoing medical needs.
- Crossover point
- The hours of paid weekly home care at which the monthly cost equals the monthly cost of assisted living in a given state.
- Level-of-care fee
- A monthly surcharge added to the base assisted living rate as a resident's care needs increase. Typically $300–$1,500/month, assessed in tiers based on the number of daily living activities requiring assistance.
- Aid and Attendance
- A VA benefit paying up to $2,300/month toward care costs for eligible veterans and surviving spouses. Available for both home care and assisted living.
- HCBS waiver
- Home and Community-Based Services waiver — a Medicaid program that pays for home care and other community-based supports for people who meet financial and functional eligibility requirements.
- Activities of Daily Living (ADLs)
- The six fundamental self-care tasks used to measure care need: bathing, dressing, transferring (moving between bed and chair), toileting, continence, and eating. The number of ADL dependencies is the primary clinical measure used to determine care level and Medicaid eligibility.
Frequently asked questions
At what point is assisted living cheaper than home care?
Assisted living becomes financially comparable to home care when paid care reaches approximately 40 hours per week nationally — though the exact crossover varies by state from approximately 26 hours in South Dakota to approximately 68 hours in Hawaii. For families who carry housing costs (rent or mortgage), the corrected crossover accounting for those costs arrives earlier than the simple calculation suggests. Use the LTCareNav Housing Transition Tool for a calculation specific to your state and housing situation.
Is it cheaper to hire a private caregiver than to use an agency?
Private caregivers typically cost $5–$15/hour less than agency caregivers. However, private arrangements carry significant risks: no backup when the caregiver is sick, no workers' compensation coverage if injured in your home, and no supervision or quality assurance. At lower hours levels the savings may be worth the tradeoff. At 30+ hours per week, the coordination and liability risks of private arrangements typically outweigh the cost difference.
Does Medicare pay for home care?
Medicare does not cover ongoing non-medical home care — the kind of regular aide assistance that drives the crossover calculation. Medicare covers short-term skilled nursing and therapy (physical, occupational, speech) when ordered by a doctor, typically following a hospitalization. This is called home health care and is distinct from home care.
Does Medicaid pay for assisted living?
Medicaid covers assisted living in most states through Home and Community-Based Services waiver programs, but coverage varies significantly. Eligibility depends on both functional need (typically 2 or more ADL dependencies) and financial criteria (asset and income limits that vary by state). See Medicaid rules in your state →
What happens when someone can no longer afford assisted living?
When private pay funds are depleted, Medicaid may cover continued care for individuals who qualify financially and functionally. The transition is significantly smoother when planned in advance — Medicaid's 5-year lookback period means planning should begin before eligibility is needed. See the Medicaid planning guide →
How do I find out the home care rate and assisted living cost in my state?
LTCareNav publishes current median home care rates and assisted living costs for all 50 states, sourced from the CareScout Cost of Care Survey and updated annually. See care costs in your state →
