How Long Can Your Parent Afford Assisted Living? Running the Runway Math

The Question Behind the $6,000 Quote

You have toured three communities. One of them felt right. The director slid a fee sheet across the table and the number at the bottom was $6,000 a month, and now you are sitting in your car in the parking lot doing arithmetic on your phone.

Most families ask the wrong version of the question at this moment. “Can we afford this?” has an easy answer: yes, for a while. The question that actually decides what happens to your parent is “for how long?” Because the failure mode in senior living is almost never the first invoice. It is year six, when the money runs out and a frail eighty-eight-year-old has to move out of the place she has finally settled into.

That gap between “can afford” and “can afford for long enough” is now something the industry measures. In July 2026 the National Investment Center for Seniors Housing & Care released a free affordability calculator built specifically to answer the duration question, and trade press reports that operators, lenders and analysts have already started using it. It is worth understanding what it does, because the same math works on your kitchen table.

What NIC’s New Calculator Actually Measures

Traditional affordability screens are snapshots. They ask whether a household’s income and assets clear the rent on move-in day, and if the answer is yes, the household counts as able to afford assisted living. NIC’s tool adds the missing dimension. It estimates how many years a household can sustain private-pay assisted living once you account for rent that rises every year, income that rises at a different rate, and assets that get drawn down in between.

Run across the 99 markets NIC tracks, using average local rents against median income and net worth for households headed by someone seventy-five or older, the tool put the median affordability duration at roughly eight years and four months as of 2025. NIC’s head of research and analytics, Lisa McCracken, framed the point plainly: affordability is not just about whether older adults can manage costs at move-in, but how long those resources can support care and housing.

Two things about that headline number matter for your family. First, it is a median across markets, and the spread between markets is wide. Second, it describes a statistical household, not yours. Your parent’s runway could be twice that or a third of it. So use the tool, but run your own numbers alongside it.

The Four-Line Version You Can Do on Paper

Before any calculator, get to a rough answer with four lines.

Monthly cost. The all-in quote, not the base rent. Include the care-level fee, the second-person fee if both parents are moving, and any medication management charge.
Monthly income. Social Security, pension, annuity payments, required minimum distributions, rental income.
The monthly gap. Line 1 minus line 2. This is what assets have to cover.
Spendable assets. Savings, brokerage accounts, retirement accounts (after tax), and net home sale proceeds if the house is actually going to be sold.

Divide line 4 by line 3, multiply by twelve, and you have a naive runway in years.

Here is why “naive” is the operative word. Take a parent with a $6,000 monthly quote, $3,000 a month of Social Security and pension income, $180,000 in savings, and a house that will net $250,000 after commissions and repairs. Assets of $430,000 against a $3,000 monthly gap gives a naive runway of just under twelve years. Comfortable.

Now let the rent grow 5% a year while her income gets a 2.5% cost-of-living adjustment. Nothing else changes. The runway drops to about nine years. Three years of care, gone, purely to the arithmetic of compounding. If she moves to a higher care tier in year three that adds $1,200 a month, the runway falls to roughly seven years and eight months. And if the house cannot be sold because your father still lives in it, the runway on savings alone is about four and a half years.

Same family. Same starting quote. Four very different futures, driven entirely by inputs most people never think to vary.

The Inputs That Actually Move the Answer

Annual rate growth is the biggest single lever. NIC’s own data has shown assisted living rents growing faster than independent living, and the sector went from 1.3% annual growth in early 2021 to the highest year-over-year increases in the history of the data collection within two years. Do not model 2% or 3% because that is what general inflation feels like. Ask each community for its actual fee increases over the past three years, in writing, and use the real figure. A community running above 95% occupancy has historically raised rates far more aggressively than one sitting below 80%, so occupancy is a clue about what is coming.

Care level creep is the input families forget entirely. The quote you were given prices your parent’s needs today. Assisted living fees are usually tiered by a points assessment, and points only go one direction. A resident who arrives needing medication reminders and ends up needing two-person transfers can move up two tiers in three years. When you run your projection, assume at least one tier increase, and ask what each tier costs in dollars rather than accepting “it depends on the assessment.”

Home sale proceeds are the input most often overstated. The number that belongs in your model is net: after agent commissions, after the repairs a fifty-year-old house needs to sell, after capital gains if applicable, and after any mortgage or home equity line. It also belongs in the model only if the sale will actually happen. If a spouse is staying put, or if a reverse mortgage is funding that spouse, the equity is not runway money. Our complete guide to funding options walks through the ways families bridge the months between move-in and closing.

The Social Security share tells you how fast the squeeze arrives. If income covers 50% of the bill, a 5% rent increase against a 2.5% COLA widens your gap by a manageable amount each year. If income covers only 20%, nearly the whole increase lands on your assets, and the drawdown accelerates every single year. Calculate what percentage of the monthly cost your parent’s guaranteed income covers. That one ratio predicts more about the shape of the runway than the asset balance does.

Sanity-Check the Assumptions Before You Trust the Number

Any calculator, NIC’s included, runs on assumptions you should look at directly.

Check whether retirement accounts are being counted gross. A $180,000 traditional IRA is not $180,000 of rent money once ordinary income tax comes out of every withdrawal. Check the investment return assumption, because a model that grows the remaining assets at 6% will show a dramatically longer runway than one that grows them at zero, and a portfolio being drawn down hard during a bad market does not behave like an average. Check whether the model assumes one person or two, since a couple moving in together pays a second-person fee but does not double the rent.

And check the tax and benefit items that sit outside the calculator entirely: the medical expense deduction that a large share of assisted living costs may qualify for, long-term care insurance benefits with their own daily caps, and VA Aid and Attendance if your parent or their late spouse served in wartime.

Compare the Runway to the Likely Stay, Not to Forever

A nine-year runway is not “not enough” or “plenty” in the abstract. It is only meaningful against how long care is likely to last.

The national median stay in assisted living is about 22 months, and roughly 60% of residents move on to skilled nursing rather than remaining in place. Federal figures put the average duration of long-term care need at 3.7 years for women and 2.2 years for men, with about 20% of people needing care for longer than five years. For most families, a nine-year runway is comfortably longer than the actual stay.

The exception is dementia, and it is a large exception. A parent who moves in at seventy-eight with early cognitive decline may need care for a decade or more, at memory care rates that run well above standard assisted living. If dementia is in the picture, model twelve years, not four, and expect the higher care tier sooner.

When the Runway Comes Up Short

If your projection ends before your parent’s likely lifespan does, you have discovered that early, which is the entire point of doing this. You have real options, and all of them work better with lead time.

Start Medicaid planning years ahead, not months. Most states look back five years at financial transactions, and gifts inside that window trigger penalty periods. An elder law attorney can structure things legally if you begin early. Waiting until assets are nearly gone removes most of the useful moves from the table.

Find out now whether the community accepts Medicaid. Many state Home and Community-Based Services waivers cover assisted living services but not room and board, and plenty of private-pay communities take no waiver residents at all. Ask directly: does this community accept the state waiver, is there a cap on waiver beds, and how many years of private pay do you require first? The answers vary enormously and they are rarely in the brochure.

Price the cheaper settings before you need them. A six to sixteen resident care home often costs meaningfully less than a large branded community for comparable hands-on care. For a dual-eligible parent who qualifies for nursing-home-level care, a PACE program can replace the private-pay bill entirely.

Do not let a marketing badge substitute for a fee history. When a shorter runway forces you to compare communities on price, understand who actually issues the “best senior living” awards before letting a ranking narrow your list.

The Point of Doing the Math Early

Running the runway math is not a pleasant afternoon. It puts a number on something families would rather leave vague, and sometimes that number is uncomfortable. But a family that knows the money lasts seven years can plan for year seven. A family that never ran the numbers finds out in the middle of a crisis, when the only remaining choice is a rushed move for someone who can least tolerate one.

Run NIC’s calculator, then run your own version with your parent’s real rent history and a care-tier bump built in. Then take both to a certified senior care advisor, an elder law attorney, and a financial planner who work with older clients. General guidance can show you the shape of the problem. Only a professional looking at your parent’s actual statements, your state’s rules, and the specific community’s contract can tell you what to do about it.
