Question 1

How is the electricity bill calculated?

Accepted Answer

The calculator determines the monthly energy consumption of each appliance in kilowatt-hours (kWh) by using the formula: (Wattage × Hours Used Daily × 30) / 1000. It then sums the kWh for all appliances and multiplies it by the average electricity tariff for your country to estimate the variable energy cost.

Question 2

Why is my actual bill different from this estimate?

Accepted Answer

This is an estimate of the usage-based portion of your bill based on average tariffs. Actual bills also include fixed daily supply charges, tiered pricing, taxes, and other fees which are not included here. Rates also vary significantly by state and provider.

Question 3

What if my appliance isn't listed?

Accepted Answer

You can add a custom appliance by clicking the 'Add Custom Appliance' button. You will need to find its wattage, which is usually listed on the appliance's label or in its manual.
