How it works
The calculator converts appliance power into kilowatts, multiplies by hours of daily use to get kilowatt-hours (kWh), then multiplies by your electricity rate to estimate cost.
Monthly cost uses your billing days input, and annual cost assumes the same daily usage pattern repeated across 365 days.
The starting rate above reflects the average residential electricity price reported for Massachusetts. Actual rates vary by utility provider and rate plan, so check your bill for the most accurate figure.
