Define your custom slab rates below, then enter your total consumed units.
This universal calculator uses a **progressive slab system** to determine the total energy charge. This method is used by many utility providers globally to encourage energy saving.
In this model, the price per unit is calculated based on which tier (or slab) of consumption it falls into. The cheapest rates are applied to the first block of units, and the rate increases progressively for higher consumption tiers, making it fair for low-volume users.
**Disclaimer:** This tool calculates only the variable energy charge based on your defined rates. Actual utility bills usually include **fixed charges, taxes, meter rentals, and other administrative fees** which are not accounted for here. Use this for estimation only.
