Saw A Spike In Electricity Bills? Here’s How You Can Calculate Your TNB Bills By Your Own

Understand your bills.
As temperatures soar, Malaysians are experiencing a surge in electricity consumption, leading to higher electricity bills. To understand these costs, it’s important to learn how to read your electricity bill and calculate the charges yourself.

Every electricity bill provides details on your previous and current meter readings. By subtracting the previous reading from the current one, you can determine your monthly electricity usage.
