What does this tool do?
Laundry costs hide in three places: the washer and dryer electricity, the water and sewer charge, and detergent. This calculator adds them into a cost per load, then scales to weekly and yearly spending.
The Formula
Cost per load = kWh × rate + water + detergent; annual = cost per load × loads per week × 52Frequently Asked Questions
Should I use cold water?
Washing in cold water cuts the energy used for heating water and is fine for most everyday loads. Use a warm wash for greasy or heavily soiled items when needed.
Is the dryer the biggest cost?
Usually yes. Drying accounts for a large share of laundry energy, so air drying or cleaning the lint filter and using a shorter cycle saves more than switching detergent.
