**Question: **

How to calculate our electricity cost?

**Answer:**

To calculate the electricity cost($) of operating an appliance, you would need to multiply the electricity consumption(kWh) by the tariff rate (say 20 cents/kWh).

To get the energy consumption (kWh), multiply the appliance wattage (kW or W) by the number of hours you use.

For example, if you use a 300W television for 4 hours per day, you are using 1200Wh or 1.2kWh per day. In one month the consumption cost will be 1.2kWh x 30 days x 0.20 $/kWh) = $7.20.
