Before and after
What the numbers say
Where each bill goes
Every charge on the statement, in rand. Hover or tap a bar to see each item as a share of the bill. Click a name in the legend to hide it.
What each unit really costs
All in cost per kWh (charges plus VAT) against the energy rate alone. The gap is fixed charges.
Billed, paid and owing
Interest on overdue accounts shows up where payments trail the bill.
