- Divide the daily wattage by 1000 to convert it to kilowatts.
- Multiply by the average number of cycles you use per week to get the weekly consumption in kWh.
- Estimate Monthly Costs:
- Multiply your weekly consumption by 4 to find the monthly consumption.
- To find out how much this costs, multiply your monthly kWh by the cost per kWh from your utility provider.
Impact on Electricity Bills
When considering your household budget, it’s essential to factor in the energy consumed by your dishwasher. Given an average cost of $0.12 per kWh, let’s dissect what this means for your finances.
Example Calculation
For instance, let’s say you have a dishwasher with the following details:
– Voltage: 120V
– Amperage: 10A
– Using it 4 times a week
Calculation:
– Wattage = 120V x 10A = 1200W = 1.2 kW
– Daily usage: 1.2 kW x 1 cycle = 1.2 kWh
– Weekly usage: 1.2 kWh x 4 = 4.8 kWh
– Monthly usage: 4.8 kWh x 4 = 19.2 kWh
– Cost: 19.2 kWh x $0.12 = $2.30 per month
This example illustrates how influential the energy consumption of your dishwasher is on your overall electric bill.
