Size the Runway to One Household: Count the Months Before You Pick the Hours
Your care runway is a count you can make from your own statements, and it changes every time the hours, the income, or the household changes.
A care runway is the number of months your available money covers the gap between the cost of care and what the family can carry without paid help. Most families size it by feel. This piece asks you to size it from your own statements, so the answer moves when the numbers move.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Write down the income that actually arrives
List each monthly deposit that will keep coming: the Social Security benefit as shown on the statement from the Social Security Administration, any pension or annuity, rental income, and any VA benefit the parent receives. Use the amount that actually lands in the account after deductions. Note the household too, because a spouse's income is counted differently from a parent's depending on the program. Medicaid eligibility and VA pension each count the household on their own rules, so do not assume one count carries over to another program. Missouri DSS and the VA publish their own household rules.
List the money you can reach
Separate money you can reach quickly from money that takes time. Checking, savings, and money market balances are easy to count. Retirement accounts may be taxed when withdrawn, and the IRS sets the tax treatment of withdrawals, so count the after-tax figure rather than the balance. Home equity is real but slow to convert. Some assets are excluded from Medicaid eligibility under federal and state rules, and a benefits counselor can tell you which ones. Count only what you can reach before the care bills come due.
Set the monthly gap
Take the monthly cost of the care plan you are sizing for, using the quoted hours or the charges on an actual invoice, then subtract the income from the first step. Any hours the family will cover at no cost should come out of the care plan, but record them as family hours, not as money. The result is the monthly gap. If the gap is zero or negative, the runway is not your constraint, and your question becomes whether the plan fits the budget at all.
Divide, then test against the calendar
Divide the reachable money by the monthly gap to get the months of runway. Then compare that number with the time it will take to get a benefit decision, because a benefit that arrives after the money runs out does not protect you. Ask the agency handling the application for its processing time in writing. A runway that covers the months before a decision gives you room to act. One that does not is a warning to start the application now.
Tax treatment of care costs
Some care expenses may be deductible if you itemize, and the IRS publication on medical and dental expenses explains what counts. Not every care cost qualifies, and the result depends on the household's full return, so treat any tax benefit as a planning input and confirm it with a tax preparer. Keep the runway figure as your planning number and note any tax benefit separately beside it.
Where the count goes wrong
The usual mistakes are counting gross income as if it were spendable, counting home equity as cash, and forgetting that the monthly gap grows whenever the hours go up. Recount whenever the care plan changes, not once at the start. For the whole picture of who pays for what, see Who Pays for Care at Home in St. Louis.
