How Much Money Does Line-Drying Clothes Actually Save?
Clothes dryers quietly rank among the most electricity-hungry appliances in an average home, which makes line-drying one of the few habit changes that can show up as a real number on a utility bill rather than a vague sense of being more careful.
The short answer
Line-drying instead of machine-drying can save a household a meaningful amount per year, mostly because a dryer draws a large amount of power for the better part of an hour per load. The exact savings depend on how many loads a household runs, local electricity rates, and how often dryer use is actually replaced rather than just occasionally skipped.
Why dryers cost so much to run
A clothes dryer works by heating air and pushing it through tumbling fabric, which takes considerably more energy than the wash cycle that precedes it. Compared to most other household appliances, a dryer is one of the higher electricity draws in the home, run for 40 minutes to an hour at a time, multiple times a week for an average household. Because that energy use is concentrated and repeated, it adds up faster than lower-draw appliances that run briefly or intermittently.
Estimating the savings with simple math
To see the order of magnitude, take a hypothetical household running five dryer loads a week. If switching those to line-drying eliminates most of that appliance’s energy use for the year, the annual savings can be estimated by multiplying loads avoided by an assumed cost per load. Using illustrative numbers — not actual rates, since those are set locally and change over time — a household might estimate something in the range of a modest but noticeable yearly figure, similar in scale to some other small fixed and variable expenses that don’t look like much individually but add up across a year. Writing the estimate down alongside other efforts to lower utility bills makes the potential savings easier to track over time rather than staying a vague impression.
What changes the number
- Load frequency. A single person doing one load a week saves far less in absolute terms than a family running a load nearly every day.
- Local electricity rates. The same number of loads costs more to dry in an area with higher electricity prices than one with lower prices, since rates vary by region and by season.
- Dryer efficiency and settings. Older or less efficient dryers, and habits like over-drying loads “just in case,” push the baseline cost higher, which makes the relative savings from skipping the dryer larger.
The tradeoffs that aren’t about money
- Time and weather dependence. Outdoor line-drying depends on sun and airflow, and doesn’t work the same way in humid or rainy climates or during winter in colder regions.
- Space constraints. Renters and apartment dwellers may not have an outdoor line at all, though indoor drying racks capture some of the same savings on a smaller scale.
- Fabric feel and wear. Some fabrics come out stiffer when air-dried, and some people find the dryer worth keeping for towels or bedding even if lighter garments go on the line.
A realistic way to approach it
Rather than treating it as all-or-nothing, many households land on a partial switch: line-drying easy items like t-shirts and lighter garments while still using the dryer for towels, sheets, or anything needed quickly. This captures a good share of the savings without requiring a full lifestyle change, and it’s a smaller commitment to test than committing to line-drying every single load from day one. Logging the change alongside other habits when you track monthly expenses makes it easier to see whether the switch is actually moving the needle.
The bottom line
Line-drying doesn’t cost anything to try, and the savings scale directly with how many dryer loads it actually replaces — a household that swaps most loads will see a bigger number than one that only occasionally skips the dryer. The honest way to estimate your own savings is to look at how many loads you currently run and multiply by your actual per-load electricity cost, rather than relying on a generic national average.
