How Much Does It Cost to Run a Dishwasher in Canada? (2026)

A dishwasher draws heavy power only while heating water and during the drying phase. Over a full cycle it averages 1 to 2 kWh, which is usually cheaper than washing the same dishes by hand with hot water.

A typical dishwasher (1,500 W) costs C$0.21 per hour, or about C$6.30 per month at 1 hours a day in Canada (average). Average running cost

Electricity price region Hours used per day

Wattage	Per hour	Per day	Per month	Per year
Low (1,200 W)	C$0.17	C$0.17	C$5.04	C$61.32
Typical (1,500 W)	C$0.21	C$0.21	C$6.30	C$76.65
High (2,400 W)	C$0.34	C$0.34	C$10.08	C$122.64

Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1 h/day ≈ 548 kWh per year.

In Canada, with electricity at C$0.14 per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical dishwasher costs C$0.21 per hour and about C$76.65 per year at 1 hours a day. Each C$1.00 of electricity buys roughly 4.8 hours of use.

How to lower the cost of running a dishwasher

Skip the heated dry option and open the door at the end of the cycle instead.
Only run full loads, and use the eco program.
Scrape plates but do not pre-rinse under hot water.
Connect to cold water if your dishwasher has its own heater and your hot water is electric.

In standby it draws about 1 W, which adds roughly 9 kWh (C$1.23) per year if it is never unplugged.
