Aging in Place vs Assisted Living: The $45,974 NPV Gap When Mortgage Rates Sit Just Below 7% and a Fed Hike Looms (September 2026)
Here's a scenario a reader sent me last week: her father is 78, has one ADL loss (bathing), owns his home outright (worth about $450,000), has $180,000 in savings, and gets $2,400/month in Social Security. She wanted to know: does it make more financial sense to modify the house and bring in help, or start touring assisted living communities now, before things get worse?
That's the right question. It's just not answerable with a rule of thumb — it's answerable with a spreadsheet. So I built one, using her numbers and the economic backdrop as of September 2026.
The Two Paths, Priced Out
Aging in place, for her father, means:
- A one-time $18,000 home modification (walk-in shower, grab bars, stairlift, entry ramp)
- In-home care starting at 20 hours/week for one ADL loss, at roughly $34/hour for a home health aide in September 2026
- Ongoing property tax, insurance, and maintenance of about $9,000/year, which has been climbing faster than general inflation
Facility care, for the same starting point, means assisted living at a median of about $5,900/month ($70,800/year), with the expectation that his ADL losses will eventually push him into memory care or a nursing home.
The two paths diverge sharply once you factor in something most calculators skip entirely: nobody's care needs stay flat. This is the same escalation dynamic covered in the 10-year NPV comparison across aging in place, assisted living, memory care, and nursing home — the ADL decline rate, not the sticker price, is what actually determines your total cost.
Modeling the ADL Escalation Curve
For this example, I used a fairly typical decline curve:
| Year | ADL losses | In-home care hours/week |
|---|---|---|
| 1 | 1 | 20 |
| 2 | 1 | 20 |
| 3 | 2 | 35 |
| 4 | 2 | 35 |
| 5 | 3 | 60 |
By Year 5, 60 hours/week of paid care is nearly round-the-clock — at that point, home care isn't really "aging in place" anymore, it's a private nursing facility inside someone's living room, and it prices out accordingly.
I applied wage growth to the hourly aide rate using the Bureau of Labor Statistics' August 2026 print: average hourly earnings rose $0.10 for the month. On a roughly $35/hour base, that's about a 3.4% annualized growth rate, which I compounded across the 5 years. On the facility side, I used the BLS's August CPI print of +0.4% for the month, which annualizes to roughly 4.9% if sustained — a reasonable stand-in for how fast facility rates and home carrying costs have been rising.
The 5-Year Nominal Cost Comparison
| Year | Aging in Place | Facility Care (AL → Nursing Home) |
|---|---|---|
| 1 | $62,360 | $70,800 |
| 2 | $45,998 | $74,340 |
| 3 | $76,042 | $78,057 |
| 4 | $78,773 | $81,960 |
| 5 | $132,171 | $141,489 |
| Total | $395,344 | $446,646 |
On raw nominal totals, aging in place comes out about $51,302 cheaper over 5 years. But nominal totals ignore the time value of money — a dollar spent in Year 5 isn't as costly, in today's terms, as a dollar spent in Year 1. That's where NPV comes in, and it's exactly the kind of analysis Dorevanti runs for you — so you don't have to build the spreadsheet yourself.
Discounting It: Why the Fed Matters Here
With the Fed weighing a rate hike this year (per the same inflation data pushing that August CPI print), the opportunity cost of keeping money invested rather than spending it goes up too — savers get better yields on the cash they're not burning on care. I used a 4.5% discount rate to reflect that environment.
| Year | Aging in Place (PV) | Facility Care (PV) |
|---|---|---|
| 1 | $59,662 | $67,748 |
| 2 | $42,120 | $68,092 |
| 3 | $66,647 | $68,411 |
| 4 | $66,057 | $68,731 |
| 5 | $106,067 | $113,545 |
| NPV Total | $340,553 | $386,527 |
The NPV gap: $45,974 in favor of aging in place — smaller than the nominal gap, because facility costs are front-loaded and aging-in-place costs back-load into the expensive Year 5 crunch, which gets discounted more heavily.
But your numbers will differ based on your specific situation. Change the discount rate, the starting ADL level, or the pace of decline, and this gap moves — sometimes across zero.
The HELOC Wrinkle
Here's a detail that's easy to miss: that $18,000 home modification has to come from somewhere. If the family doesn't have cash sitting around, they're financing it — and as of Friday, September 11, mortgage and HELOC rates are sitting just below 7%. At 6.98% amortized over 5 years, that $18,000 modification actually costs about $21,378 in total payments — a hidden $3,378 in interest that most people forget to add to the "aging in place" side of the ledger.
Shrink the NPV gap by that amount and you're at roughly $42,596 — still favoring aging in place, but the margin keeps thinning as financing costs rise. This is the same rate sensitivity explored in the HELOC-rate-driven cost crossover analysis — when borrowing costs move a point, so does your break-even.
Medicaid Spend-Down: The Part Nobody Wants to Model
At $180,000 in savings, this family isn't destitute, but they're not insulated either. If ADL losses accelerate faster than modeled — say Year 3 hits nursing-home-level care instead of Year 5 — private-pay nursing home costs of $116,000–$141,000/year would burn through $180,000 in savings in under 18 months. That's the point where Medicaid spend-down planning stops being theoretical.
Facility care, especially skilled nursing, has a clearer Medicaid pathway once assets are spent down. Aging in place has home- and community-based service (HCBS) waivers in most states, but they often carry waitlists — meaning a family that spends down assets while aging in place may face a gap between "broke" and "covered." That gap is real money, and it's rarely in anyone's back-of-envelope math.
VA Aid & Attendance: A Flat Subsidy, Not a Tiebreaker
If the veteran in this scenario qualifies for VA Aid & Attendance with a spouse, the 2026 benefit runs around $2,850/month, or $34,200/year. Applied evenly across both paths — because A&A can apply to in-home care that meets VA criteria, not just facility care — it reduces both totals by roughly $171,000 over 5 years and leaves the relative gap between aging in place and facility care essentially unchanged. That's a genuinely useful and under-appreciated insight: A&A softens the total bill, but it doesn't usually flip which option is cheaper. Confirm your own eligibility specifics with a VA-accredited benefits counselor, since edge cases around in-home qualification do exist — this is covered in more detail in the VA Aid & Attendance NPV gap breakdown.
Two Small But Real Line Items
Caregiving generates its own errand-running costs — more trips for groceries, prescriptions, and appointments as ADL losses pile up, plus gas. A rewards card with strong grocery and gas categories (the kind PenFed's new Defender card is positioning itself around) can offset a meaningful chunk of those recurring costs over a multi-year care timeline. And if a facility move means out-of-town family flying in or booking short-term lodging near the new community, a travel rewards card's trip protections (the value proposition NerdWallet highlights with the Chase Sapphire lineup) can matter more than people expect during a stressful transition. Neither changes the core NPV math — but both are real dollars that show up in the actual experience of either path.
What Actually Determines Your Crossover
This one family's numbers say aging in place wins by about $42,600–$45,974 in NPV terms over 5 years. But the variables that produced that number are all personal:
- Starting ADL level and decline speed — a faster decline curve compresses the timeline to expensive care and can flip the winner
- Home equity and financing costs — cash-in-hand vs. a HELOC at nearly 7% changes the aging-in-place cost meaningfully
- Local aide wages and facility rates — these move independently, and the gap between their growth rates is often the whole ballgame
- Discount rate assumptions — tied to where you think rates go from here, which is exactly what the Fed's next move will help answer
- Life expectancy — a shorter horizon favors whichever option has lower upfront costs; a longer one rewards whichever compounds more slowly
You can model this for your specific situation at Dorevanti — plugging in your own ADL trajectory, local wage data, mortgage/HELOC rate, savings balance, and VA benefit eligibility to get your actual NPV crossover, not a generic estimate built on someone else's numbers.
The math doesn't care which option feels more comfortable. It just tells you, for your household, which one costs less — and by how much.
