How to read your electricity bill

Use this quick guide to find the total amount and the optional fixed part on your electricity bill.

1. Check the bill period and the total

The green bar shows the bill period and the green circle shows the total to pay for this bill. That’s the number you put in “Total amount (€)”.

Example bill with billing period and total highlighted

In this case, the bill period is from 27/08/2025 to 26/06/2025 and the total amount to input would be € 129.86.


2. Separate variable vs fixed part

The yellow boxes show the variable part (what changes with how much you use – kWh, m³, etc.). The red area at the bottom shows the fixed part (what stays the same independently of your consumption like taxes, fees and CAV in this example).

Example bill with fixed and variable parts highlighted

In this case, the important parts to input and remember are: The Total bill amount: € 129.86
and the Fixed part (1)+(2)+(3): € 38.01.

The variable part will be automatically calculated by Bill by Days once you input these two numbers. in this case it would be € 91.85, the yellow area.


In Bill by Days you can type the full Total amount (€), and – if you want – the Fixed part (€). We automatically split the variable part across days and roommates for you.
