Common estimate questions
How is the electricity bill estimate calculated?
The estimator uses the provider, units, protected status, and available tariff, tax, and adjustment rules. It is a planning estimate, not an official bill.
Why can my official bill be different?
Official bills can include fuel price adjustments, quarterly adjustments, arrears, meter-reading date differences, taxes, and provider-specific rounding.
Do I need to create an account?
No. You can run a quick estimate without signup. An account is useful when you want to save bills, compare estimates with real bills, and see trends.
Can I estimate from meter readings?
Yes. You can enter previous and current readings, or enter units directly if you already know your consumed units.
