Aging in Place vs Assisted Living: The $59,109 NPV Gap VA Aid & Attendance Can't Close (September 2026 Calculator Walkthrough)

The scenario: Dorothy, 78, one ADL loss, and a spreadsheet nobody handed her

Dorothy is 78. She owns her home outright ($420,000, no mortgage), has $180,000 in CDs, collects $2,100/month in Social Security, and recently started needing help bathing — her first ADL (activities of daily living) loss. Her daughter is doing what a lot of adult children do right now: pulling up assisted living brochures and a home health aide quote and trying to figure out which number is smaller.

The honest answer is that neither brochure nor quote tells you that. What tells you is a net present value (NPV) comparison that accounts for how Dorothy's care needs will escalate, what benefits she can stack on top, and how a Medicaid spend-down clock starts ticking the moment she needs facility-level care. Below is that math, built with real September 2026 economic inputs. Your numbers will come out differently — that's the point.

Three numbers from this week's data that actually move your math

Before the scenario, three figures from the Bureau of Labor Statistics and NerdWallet's mortgage coverage matter more than they look:

  • CPI rose just 0.1% in July 2026 — one of the cooler monthly readings this year. If you're using headline CPI to project how fast your care costs will grow, you'll underestimate.
  • Average hourly earnings rose $0.10 in August 2026, with unemployment holding at 4.1% and payrolls up 162,000. A $0.10 monthly gain annualizes to roughly 3.3% wage growth — and home health aide wages track labor market tightness, not the CPI print. That 3.3% is the number that should drive your in-home care cost escalation, not the 0.1% CPI figure.
  • Mortgage rates rose through the week on Fed-hike expectations, then eased slightly by Friday, September 4. If you're financing home modifications with a HELOC, the rate you lock in depends on which day you apply — a detail that's easy to miss when you're focused on the bigger facility-vs-home decision.

This is exactly the kind of variable-tracking that makes rule-of-thumb answers unreliable. Dorevanti pulls current wage growth, CPI, and rate data into your projection automatically instead of asking you to eyeball it.

Building Dorothy's 5-year NPV

Assumptions (all labeled as example inputs, not universal defaults):

  • Home modification (grab bars, walk-in shower, stairlift): $18,000, one-time, Year 0
  • Home health aide: $33/hour, 20 hrs/week at 1 ADL loss, growing 3.3%/year (from the BLS wage data above)
  • Home carrying costs (property tax, insurance, maintenance): $9,000/year, growing 3%/year
  • ADL escalation: 2 ADL losses by Year 3, pushing in-home care to 40 hrs/week
  • Assisted living: $70,800/year base, growing 5%/year, plus a 15% care-tier surcharge once she hits 2 ADL losses
  • Discount rate: 3.51% — Dorothy's after-tax CD yield (4.5% APY taxed at her 22% bracket, per NerdWallet's CD tax math), representing what her money would otherwise earn
YearAging-in-Place (nominal)Assisted Living (nominal)
0$18,000 (mod)—
1$43,320$70,800
2$44,724$74,340
3$82,785$89,766
4$85,484$94,254
5$88,275$98,967

Discounted at 3.51%, the 5-year NPV totals come out to:

  • Aging in place: $324,966
  • Assisted living: $384,075

That's a $59,109 gap in favor of aging in place — driven almost entirely by what happens in Years 1–2, before the ADL escalation and care-tier surcharge hit. This is the same dynamic explored in Aging in Place vs Assisted Living: The $81,700 NPV Gap at 2 ADL Losses, where wage growth cooling to 3% widened the gap in the home-based option's favor. Building this table by hand takes a while — this is the kind of analysis Dorevanti runs for you, so you don't have to build the spreadsheet yourself.

The VA Aid & Attendance insight nobody points out

Say Dorothy's late husband was a veteran, and she qualifies for a Survivor's Pension with Aid & Attendance — an example benefit in the $1,400–$1,800/month range depending on marital and asset status. The instinct is to apply that benefit and recheck who wins.

Here's the part that surprises people: if the same monthly benefit is available regardless of which path she chooses, it doesn't change the winner. Subtracting an identical income stream from both the aging-in-place total and the assisted living total shifts both NPVs down by roughly the same discounted amount — the gap stays close to $59,000. VA Aid & Attendance lowers Dorothy's out-of-pocket cost either way; it doesn't tip the scale between the two options.

That's a genuinely useful thing to know before you spend an afternoon on VA paperwork expecting it to change your decision. It changes your affordability, not your comparison. For the mechanics of applying VA benefits inside a full NPV formula, see How to Calculate Your Aging-in-Place vs Assisted Living Cost Crossover: The 5-Step NPV Formula.

Where Medicaid spend-down changes everything: nursing home, not assisted living

This is where the math genuinely diverges by facility type, and it's the piece most cost calculators skip entirely.

Dorothy has $180,000 in countable assets. Most state Medicaid programs require spend-down to roughly $2,000 before covering long-term care — but that coverage is structured very differently depending on the setting:

  • Nursing home care is broadly covered by Medicaid in every state once you spend down.
  • Assisted living is covered by Medicaid in only some states, usually through a Home and Community-Based Services (HCBS) waiver with waitlists — not a guarantee.
  • Aging in place may qualify for limited HCBS waiver hours, but rarely enough to replace private-pay care hours once ADL losses stack up.

Run Dorothy's spend-down clock for a nursing home scenario: if nursing home costs run $9,700/month and her income ($2,100 SS + modest pension, say $3,600 total) covers part of it, she'd draw roughly $6,100/month from savings. At $178,000 spendable ($180,000 minus the $2,000 Medicaid asset floor), that's:

$178,000 ÷ $6,100/month ≈ 29 months (about 2.4 years) until Medicaid eligibility kicks in.

After that point, the state picks up the nursing home bill — a floor that simply doesn't exist for the assisted living or aging-in-place paths in most states. This is exactly the crossover mechanic detailed in Aging in Place vs Nursing Home: When the 10-Year Cost Flips at 3 ADL Loss Levels — the nursing home NPV curve doesn't rise forever, it plateaus once Medicaid takes over. Assisted living's curve keeps climbing on your own dime the whole time.

The life expectancy adjustment that changes your horizon

At 78, Dorothy's individualized life expectancy — not the generic actuarial average, but one adjusted for her actual health status and ADL trajectory — might run another 8–11 years, not the 5-year window used above. Extend the model to 10 years and two things happen simultaneously:

  1. The aging-in-place path likely crosses into 24/7 care territory (3+ ADL losses) somewhere around Year 6–7, at which point hourly aide costs can exceed facility costs on a pure cash-flow basis.
  2. The nursing home path's Medicaid floor (kicking in around Year 2.4 in this example) means its NPV growth slows down relative to assisted living's, which has no such floor.

That combination is why a 5-year snapshot and a 10-year snapshot can point to different answers for the same person. If your own timeline is longer or shorter than Dorothy's, your crossover year moves — sometimes by a lot. The full 10-year, four-way comparison (aging in place, assisted living, memory care, nursing home) with sensitivity to ADL decline rate is broken down in Aging in Place vs Assisted Living vs Memory Care vs Nursing Home: The NPV Gap Ranges From -$116,000 to +$298,000.

Your numbers will differ — here's why that's not a caveat, it's the whole point

Dorothy's $59,109 gap depends on inputs that are specific to her: her home is paid off (no mortgage rate exposure), her CD yield sets her discount rate, her ADL decline timeline assumes 2 losses by Year 3, and her state's Medicaid waiver availability is unknown in this example. Change any one of those and the crossover year moves:

  • A HELOC-funded modification instead of cash from CDs adds financing cost at whatever rate you lock in this week — and this week's rate moved up, then down, in a matter of days.
  • A slower ADL decline pushes the crossover further out, favoring aging in place longer.
  • A state with a robust assisted living Medicaid waiver closes part of the gap that nursing home currently has to itself.
  • A different tax bracket changes your discount rate, which changes every downstream NPV number.

That's why "assisted living costs $70,800 a year, in-home care costs $34,320" isn't actually an answer — it's the first two data points of a much longer calculation involving escalation curves, benefit stacking, and spend-down timing. You can model this for your specific situation, with your home value, your ADL trajectory, your state's Medicaid rules, and this month's actual rate and wage data, at Dorevanti.
