Time-of-Day Cost Estimator

Calculate the estimated daily cost of household items on our Time-of-Day Rate. 

With our new Time-of-Day (5-8 p.m.) Rate, choosing when to run your appliances is now more important than ever. Explore different seasonal rates, appliances and time periods to find ways to save.

Get started

  1. Select a seasonal rate (summer or non-summer)
  2. Choose a room
  3. Click on an appliance and select the time of day you normally use it
  4. Look for opportunities to save money by shifting use to less expensive time periods



Each item's estimated use per day and the load run time for dishwashers, clothes washers and dryers are based on SMUD data and research.

Appliance Load run time assumption
Dishwasher (standard and high-efficiency) 2 hours
Clothes washer (standard and high-efficiency) 1 hour
Clothes dryer (standard and high-efficiency) 45 minutes

The Time-of-Day Cost Estimator is for illustrative purposes. We use wattage estimates based on our research. Your item’s actual wattage values may vary depending on age and features. To find exact wattage for your item, check your owner’s manual or data plate.
