Why did my bill go up?

Dollars change when you use more kilowatt-hours, when the price per kilowatt-hour changes, or both. Enter last month and this month and the checker separates those two effects. It does not see your account.

State Utility

The utility list loads when you choose a state. ZIP-to-utility matching needs an NREL key and is not in this build. Needs verification.

Last month, kWh Last month, dollars This month, kWh This month, dollars

What else changed?

The weather was hotter or colder The bill says the read was estimated A rate, fuel charge, or rider changed I am on a time-of-use plan I added an EV, electric heat, or a pool I switched supplier or plan I moved, or the home was empty I think data-center load is involved

Why did my electric bill go up?

What if I only know the dollar total?

The split needs both months of kilowatt-hours and dollars. The dollar total alone cannot tell usage from price.
