The Cheapest Time to Do Laundry Is When Everyone Else Is Asleep

If you’ve ever wondered when the most cost-effective time to wash clothes is, the answer might surprise you: very early in the morning or late at night. These off-peak hours—typically before 7 a.m. or after 9 p.m.—are when energy demand drops significantly, and so do electricity rates.

Why does timing matter? Most utility companies use a system called time-of-use pricing, where electricity costs more during peak hours—usually midday to early evening—when everyone’s using appliances, lights, and HVAC systems. Running your washing machine during low-demand periods means it draws power when rates are at their lowest.

Not only does this save money, but it’s also better for the environment. Less energy demand means less strain on the grid, which often relies on fossil fuels during high-usage times. By shifting laundry to quieter hours, you're helping reduce carbon emissions, too.

Modern washing machines make this easy. You don’t have to be awake to benefit—just set a timer. Start a cycle before bed or program it to begin at 5 a.m. Many newer models offer delayed start features, so your laundry finishes right when you wake up.

Of course, keep your neighbors in mind. A loud machine at midnight might not win you any popularity contests. But if your unit is in a basement or utility room, nighttime washing is a quiet, smart move.

Ultimately, a small change in routine can add up to real savings over time—both on your bill and for the planet. So next time you're sorting clothes, think about the clock. The cheapest time to wash isn't when the sun’s up—it’s when it’s not.
