How much electricity does a dishwasher use per cycle?
Short answer: Most dishwashers use about 0.7–1.5 kWh per cycle: eco programs around 0.7–1.0 kWh and hot or intensive programs 1.2–1.5 kWh. At 20 cycles a month that is roughly 14–30 kWh.

Tip: Running full loads on the eco program is the single biggest dishwasher saving.

Typical residential averages: USA 18.3¢/kWh (EIA, July 2026; California 33.6¢, Texas 15.9¢), UK about £0.25/kWh, Germany about €0.38/kWh, UAE about AED 0.23–0.38/kWh, Canada about C$0.13–0.20/kWh and Australia about A$0.30–0.35/kWh. The kWh result is the same in every country; only the cost changes.

Use this page to estimate dishwasher energy from cycle time and number of monthly cycles. Eco mode and full loads can reduce waste.
This is a preliminary planning estimate. For certified audits, use site measurement and nameplate readings.
FAQ
Is a dishwasher cheaper than washing by hand?
Often yes for full loads, especially compared with hand washing using hot water from an electric geyser, because a modern dishwasher heats only 10–15 litres of water per cycle.
Is this result exact?
It is an engineering estimate using user inputs. Exact result needs actual meter/nameplate data.
Can I use it for audit report?
Yes, as a preliminary calculation and supporting estimate.
Cycle tip
Run full loads and use eco mode when possible. Daily partial loads can increase both water and energy cost.
Accuracy note
The result is a planning estimate. Use nameplate wattage, measured runtime and current tariff for professional-level accuracy.
