Explanation: The total bill is calculated by multiplying energy consumption by the rate per unit, then adding any fixed service charges that apply regardless of usage.
Details: Understanding electricity bill calculation helps consumers budget effectively, identify high consumption patterns, and make informed decisions about energy usage and conservation.

Q4: Why is my actual bill different from this calculation?
A: Actual bills may include taxes, surcharges, tiered pricing, time-of-use rates, or other fees not accounted for in this basic calculation.
Q5: How can I reduce my electricity bill?
A: Use energy-efficient appliances, turn off unused devices, optimize heating/cooling settings, and consider shifting usage to off-peak hours if available.
