Frequently Asked Questions
Where do I find the wattage of my appliance?
Check the appliance's nameplate label (usually on the back or bottom), the user manual, or the manufacturer's website. Most appliances list power consumption in watts (W).
How do I find my electricity rate?
Check your utility bill for the 'rate per kWh' or 'cost per kilowatt-hour'. It's usually listed in the billing section. Rates vary by location and utility provider.
Is this calculation accurate?
Yes, the calculation uses the standard formula: (Wattage × Hours) / 1000 = kWh, then kWh × Rate = Cost. Results are accurate for consistent usage patterns.
Can I track multiple appliances?
Yes! Add as many appliances as you want. The calculator shows individual costs and totals for easy comparison.
What if my appliance uses a range of wattages?
Use the average wattage listed on the label. For appliances with variable power (like ovens or space heaters), use the maximum wattage for a conservative estimate.
