This week, I responded to a post in the r/Frugal forum on Reddit asking, "What's your lowest payoff frugal tip?" That "lowest" is not a typo; the questioner was interested not in learning tricks to save a bundle of money, but in hearing about frugal habits that are "more about principle than the actual savings." Comments included things like reusing plastic bags, cutting dryer sheets in half, and saving packaging items like twist ties and rubber bands—a habit one commenter said has saved them "tens of cents."
I chimed in to talk about how I always hang my laundry, weather permitting, even though the savings are minimal. Each load I hang instead of running it through the dryer saves about a quarter-therm of gas, which is currently worth about 40 cents—more than the 24 cents it cost when I first wrote about it in 2012, but still far from impressive. Since it takes at least 15 minutes to hang the laundry in the morning and take it down in the evening, that works out to $1.60 an hour. That's barely 10 percent of New Jersey's current minimum wage of $15.92 an hour, making line-drying an even worse financial deal than it was in 2012. And it reduces my carbon footprint by a mere three pounds.
In my 2012 post, I concluded that the real reason I hang laundry is because it makes me feel good, even if the practical benefits are small. But when I commented about it on Reddit, another Redditor replied to point out that there is another practical benefit as well: "you’re extending the life of your clothes by hang drying them instead of blasting them in the dryer." Now, in theory, I knew this already, but I'd never been sure just how significant a perk it really was. After all, how could I tell how much longer my clothes were lasting as a result of being hang-dried? Short of buying two identical garments and line-drying one while tumble-drying the other, how would I even test it?
But just one day after seeing that Reddit post, I hit on what economists call a natural experiment. I was darning up some holes in my blue knit shorts, the pair I'd bought at Sears back in 2015 when there still was a Sears, and it occurred to me that at the time I bought them, I hadn't expected them to last very long. In college, I'd owned a few pairs of sport knit pants from the same company, and I'd quit buying them because they always developed holes within a matter of months. But now, here were these shorts just getting their first little holes after 11 years. So either Lands' End had started using much sturdier fabric some time between 1995 and 2015—not a very likely scenario—or line-drying had made the difference.
However, it isn't quite fair to say these shorts lasted 11 years when their predecessors lasted less than 1. Being shorts, they were only worn during the summertime, or about 3 months out of every 12. Still, that means they remained intact over 33 months of use, while the knit pants I owned in college never made it more than 6 months. In other words, line-drying the shorts had prolonged their lifespan more than fivefold.
I wouldn't go so far as to extrapolate from this that all my clothes are lasting five times as long thanks to line-drying. These shorts are a knitted cotton fabric, like a T-shirt, and some of the other comments in the Reddit thread suggest these are particularly vulnerable to dryer damage. However, probably about half the garments in our typical laundry load are knitted items, including T-shirts, socks, and undies. If all these garments are lasting five times as long, we're saving 80 percent of what we'd otherwise spend on them. That's roughly a 40 percent savings on clothing as a whole, even if the other half of our clothes gains no benefit at all from line-drying.
How much is this in dollar terms? Well, according to my budget spreadsheet (yes, of course I have a budget spreadsheet), Brian and I spend an average of $389 per year on clothing and shoes. Let's assume shoes, which don't go in the laundry, account for $89 of that, leaving us a nice round $300 a year for clothing. If this figure has had 40 percent knocked off it by line drying, that means our clothing budget without line-drying would be $500, or $200 higher. We do a little over one load of laundry per week—say 60 loads per year—and we line-dry about three-quarters of them, or 45 loads. So that means each load I hang on the line is saving us not just a measly 40 cents on fuel, but also about $4.44 on clothing costs. Add it all up, and that's a savings of $4.84 per load for roughly 15 minutes of work, or $19.36 per hour—well above our state minimum wage, and more than 2.5 times the paltry federal minimum wage of $7.25 per hour.
Mind you, knowing all this isn't likely to change my behavior in any meaningful way. I'll still line-dry my clothes in nice weather and resort to the dryer only if it's freezing cold or rains for days on end. But now, each time I do it, I'll have the satisfaction of knowing that it actually is saving us money. Spending 15 minutes out in the sun and fresh air will be just the cherry on top.
