# How is my bill calculated?

### How is my bill calculated?
### 

Your bill is based on:

1. **Energy supply charges** – the cost of electricity or gas you actually use (measured in kWh or therms) multiplied by your plan’s rate.
2. **Delivery charges** – set by your local utility, covering maintenance of wires, pipes, and infrastructure.
3. **Taxes and fees** – state/local regulatory charges.

You’ll see a breakdown on every bill showing supply vs delivery.
