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.
