How often are electricity bills issued, and how do I match this calculator to my bill? +

Billing frequency depends on the utility — most bill monthly, though some bill every two months or quarterly. Use the billing period selector above to match your own utility's cycle: if your bill covers two months of usage, choose the bi-monthly option so the fixed charges and tax are calculated over the correct period instead of being doubled or understated.
