What Are Slabs in Electricity Billing?
Electricity charges are calculated using slabs. A slab is a range of electricity units with a fixed rate. For example:
| Units | Rate per kWh |
|---|
The more units you consume, the higher the slab rates may apply. This calculator uses telescopic calculation, meaning each slab is charged only for units within that range.
