Typical electricity cost
How much does a Garbage Disposal cost to run?
Based on typical usage
A Garbage Disposal typically uses about 700 watts, costing around $0.11 per hour at $0.15 per kWh.
At typical use (0.1 hours per day), that's about $0.32 per month and $3.83 per year.
Based on
- 700 watts
- 0.1 hours per day
- $0.15 per kWh
What affects cost most
- Average hours used per day
- Electricity rate in dollars per kWh
- Preheat time, cooking temperature, and batch size
How it works: Daily cost uses wattage, hours per day, and electricity rate. Monthly uses daily × 30; yearly uses daily × 365.

Get a better estimate and keep costs down
Defaults are a starting point. Real cost changes most when runtime, wattage, and your electricity rate differ from the benchmark assumptions.
What changes cost most
- Average hours used per day
- Electricity rate in dollars per kWh
- Preheat time, cooking temperature, and batch size
How to get a better estimate and lower cost
- Replace the default electricity rate with the actual rate from your latest power bill.
- Adjust daily runtime to match how long you actually use the equipment.
- Run the disposal only long enough to clear waste.
- Avoid overloading it with fibrous or bulky scraps.
- Keep blades and chambers clean for efficient operation.
- Compost appropriate scraps to reduce disposal use.
