Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your food processor.
This setup uses about 1 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 0.05 | $0.11 |
| Page example | 0.1 | $0.23 |
| Longer runtime | 0.15 | $0.34 |
Same 400-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
0.4 kW × 0.1 hr × $0.1883 = $0.01 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
Food processors have strong motors but run for mere seconds per task, resulting in negligible energy consumption over a year.
Use this as a baseline until you can check the label or measure the food processor directly. Model, settings, condition, climate, and household routine can all change the result.

- 03
Length of processing time
Ways to spend less
- Pulse the blade instead of running it continuously.
- Chop larger vegetables into chunks before processing.
- Unplug the appliance when stored on the counter.
