A quick way to estimate an appliance's running cost, or sanity-check your utility bill.
Your rate per kWh is on your electric bill, usually listed as '$/kWh' or similar — rates often vary by time of day (peak vs. off-peak) or season, so a single flat rate here is an approximation, not a perfectly precise bill.
To estimate what a specific appliance costs to run, multiply its wattage by hours used, divide by 1000 to get kWh, then use this calculator — a good way to spot which appliances are actually driving up your bill.
