How we work it out
- We price the month with today’s tariff for homes, from the calculator’s official rates.
- Then we apply the prepaid rules of the state order: a rebate, prepaid rates, and the time-of-day rates of smart meters.
- Units used earlier in the month decide the slab of the new units.
- Discoms take money each day, but the slabs count the whole month. Your daily balance can differ from our figures for the month.
Questions
How many units do I get for a Rs 500 recharge in Kerala?
At today’s tariff, about 102 units, if it is the first recharge of the month and it also pays the fixed charge. Later in the month, the units depend on the slab you are in.
Is prepaid cheaper than post-paid?
We found no prepaid rebate in the current tariff order. The calculator uses the normal tariff.
Why do I get fewer units late in the month?
The slabs count the units of the whole month. Units late in the month can fall in a higher slab, so each unit costs more.
