How Many Days of Your Life Does Your Home Cost?

Having spent years selling and appraising real estate, I’m familiar with the usual measures for valuing a house. Price per square foot, comparisons to similar properties, and the guideline of keeping housing at or below 25 percent of what a household earns are all useful.

Less formally, many of us also measure our homes against those of our neighbors. We notice whether others have more space, a newly remodeled kitchen, professional landscaping, or other high-end features. Of course, we usually have no way of knowing their income, their debt, or whether they lie awake worrying about their mortgage payments.

Comparing your house to a market, a guideline, or someone else’s property does not always have much to do with your family’s life or needs.

Here’s a different way to think about it. Total all the costs related to housing in a year—the mortgage or rent plus taxes, insurance, and upkeep. Divide that number by a single day’s earnings after taxes. The answer is roughly how many days a year you work for the roof over your head.

Here is the arithmetic for a household with take-home pay of $60,000 a year and housing costs of $18,000 a year. Divide $60,000 by 260, the typical number of workdays in a year. The result is $230 per day. Divide the $18,000 housing cost by $230, and you get 78 days, a little more than one-third of your annual workdays. This number aligns with information from Harvard’s Joint Center for Housing Studies that half of all renters and a quarter of homeowners spend 30 percent or more of their income on housing.
