How Can You Calculate the Bill Yourself?
You can easily calculate your electricity bill by following a simple step-by-step process based on your consumption and tariff category.
First, check your current month’s meter reading to determine total units consumed. Then identify your applicable tariff type, such as domestic or commercial, since billing rates differ for each category. Domestic consumers are further classified into protected and non-protected groups, which also affects the final bill calculation.
Next, refer to the relevant bill slab according to your consumption. Multiply the total units by the applicable tariff rate. After that, include government taxes such as sales tax along with fixed charges like meter rent.
Finally, add all charges together to get your total electricity bill amount.
