Calculate your cost
Start with a representative input, then edit all three numbers.
This setup uses about 54 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 0.5 | $5.08 |
| Starting point | 1 | $10.17 |
| Longer runtime | 1.5 | $15.25 |
Same 1,800-watt input and 18.83¢/kWh rate; only runtime changes.
The quick formula
1.8 kW × 1 hours × $0.1883 = $0.34 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
A dishwasher's peak draw comes from water heating and heated drying, not from the circulation pump alone. The listed watts are therefore most useful as an average cycle assumption rather than a continuous draw.
The starting values keep this page useful before you have a label or meter reading. They do not describe every model, climate, operating mode, or household.
What changes the cost?
- 01
Cycle duration, water-heating stages, and heated dry
- 02
Incoming water temperature and appliance efficiency
- 03
Load frequency and selected soil setting
Ways to spend less
- Run a full load and choose an appropriate eco cycle.
- Skip heated drying when air drying works for the load.
- Clean the filter so repeated or heavy cycles are less likely.
