FAQ

Frequently Asked Questions

How do I find the cheapest electricity provider?

Use comparison portals, check the total annual cost (not just the unit price), consider the contract term and cancellation period, and be wary of high bonuses that mask expensive tariffs.

What should I look for when switching electricity providers?

Check the contract duration (12 months max recommended), price guarantee period, cancellation notice period, and whether the tariff includes eco-electricity certification. The switch itself is handled by the new provider.

Which electricity prices are baked into the calculation?

An average household electricity price of about 36 ct/kWh is used (Germany 2026). Actual prices vary by provider and tariff — the calculator allows you to enter your own value.

Key Data and Facts

Electricity price 2026: approx. 35-40 ct/kWh. Default supply often more expensive than alternative providers. Switching providers often saves 100-300 euros/year. Notice period: usually 2 weeks to 3 months.

Step-by-Step Guide

How to calculate your electricity costs and savings potential step by step: 1. Determine annual consumption: read off your consumption from your last annual bill (in kWh). If not available, estimate it: 1 person about 1,500 kWh, 2 people about 2,500 kWh, 4 people about 4,000 kWh. 2. Enter your current electricity tariff: the unit price in ct/kWh (on average 35-40 ct/kWh in 2026) and the monthly base price (about 8-15 EUR/month). 3. Calculate annual costs: annual costs = (consumption x unit price) + (base price x 12). 4. Determine the monthly instalment: instalment = annual costs / 12. 5. Carry out a tariff comparison: compare your current tariff with cheaper providers. The basic supply tariff is often 5-10 ct/kWh more expensive than alternative tariffs. 6. Observe the notice period: basic supply 2 weeks, special contracts usually 1-3 months.

Calculation Example

Three-person household, 3,200 kWh/year, unit rate 0.38 EUR/kWh, standing charge 12 EUR/month: annual cost = (3,200 x 0.38) + (12 x 12) = 1,216 + 144 = 1,360 EUR. Monthly instalment: 113 EUR.
