This retirement living expense has nowhere to go but up. The annual cost of a private room in a nursing home has cracked the six-figure mark, according to Genworth Financial. The national annual median cost of a private room in a nursing home is $100,375, the insurer found in its 2018 Cost of Care study. Overall, the rising cost of care has outpaced inflation. The Consumer Price Index for all urban consumers was 2.1 percent for the first half of 2018. The annual median cost of a room at an assisted living facility grew by 6.67 percent between 2017 and 2018. Meanwhile, the cost of a shared room in a nursing home jumped by 4.11 percent.

"These costs are outpacing the U.S. inflation rate, which is becoming greater competition when it comes to our wallet share," said Gordon Saunders, senior brand marketing manager at Genworth. Here's a breakdown of the costliest places to seek care.

Alaska is home to the most expensive location for care in a nursing home. There, the annual median cost of a nursing home stay in a private room is $330,873, Genworth found. The District of Columbia has the highest price tag for a stay in a one-bedroom dwelling at an assisted living facility: The annual median cost is $111,195. Assisted living facilities offer residents more independence and less medical care and assistance than nursing homes. Finally, for individuals who'd like to receive care at home and still live largely on their own, there's the option of having a home health aide come to visit. This service costs the most in Hawaii. Patients can expect to pay a median annual cost of $68,640 for 44 hours a week of home-health service.

With an estimated 10,000 boomers turning 65 every day, experts say the growing demand for support services is raising the cost of care. "With people living longer, we're seeing a greater demand for that care and assistance as we age," said Saunders. "This is an issue of supply and demand." "Some factors we start to see that are impacting the home care business is competition for caregivers and minimum wage increases in some states, which affects businesses bottom line," he said. Indeed, home-health aides are expected to be a growing job sector, with a projected growth rate of 41 percent from 2016 to 2026, but median annual wages of $23,210, according to the Bureau of Labor Statistics.
