As the cost of assisted living facilities and nursing homes keeps rising, the option of bringing long-term care services into the home keeps getting more attractive.

According to the Genworth 2014 Cost of Care Survey, the national median cost of ALFs has increased by 4.25 percent annually over the past five years, to $3,500 per month. The national median cost of a private room in a nursing home has increased by 4.19 percent annually, to $240 per day ($87,600 per year).

Meanwhile, the national median for homemaker services has increased by only 1.2 percent per year, to $19 per hour; the national median for home health aide services has increased by 1.32 percent, to $20 per hour. (Homemakers clean rooms, make beds, wash laundry and prepare meals. Aides also deliver medication and personal assistance.)
