FAQ
Frequently Asked Questions
What is the average gas consumption per household?
Average gas consumption for heating in Germany is about 140 kWh per square meter per year. A 100 m2 apartment uses approximately 14,000 kWh, plus 800-1,200 kWh for hot water.
How can I reduce my gas consumption?
Reduce room temperature by 1 degree (saves about 6%), insulate heating pipes, ventilate properly (brief cross-ventilation), use programmable thermostats, and maintain the heating system regularly.
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.

Quick Answer
The gas consumption calculator computes the annual gas costs and compares your consumption with average values for heating and hot water.
What is the Gas Consumption Calculator?
The gas consumption calculator computes the annual gas costs and compares your consumption with average values for heating and hot water.
How does the Gas Consumption Calculator work?
Enter your gas consumption (kWh or cubic metres) and gas price. The calculator computes annual costs. For cubic metres the conversion to kWh is applied (factor approx. 10). A comparison with average values shows savings potential.
Key Data and Facts
Average gas consumption: approx. 120-160 kWh/sqm/year. Gas price 2026: approx. 10-14 ct/kWh. Conversion: 1 m3 gas approx. 10 kWh (depending on calorific value and condition factor).
Step-by-Step Guide
How to calculate your gas consumption and costs step by step: 1. Read off your gas consumption: read the consumption in kWh from your annual statement. If only cubic metres are given, convert: kWh = m3 x calorific value x state number. Typical calorific value for natural gas H: approx. 10-12 kWh/m3, state number approx. 0.9-1.0. Simplified: 1 m3 ≈ 10 kWh. 2. Enter the gas price: in 2026 the current gas price is approx. 10-14 ct/kWh including all charges. 3. Calculate the annual cost: cost = consumption (kWh) x gas price (EUR/kWh). Add an annual base price (approx. 80-200 EUR). 4. Compare consumption with average values: unrenovated old building: approx. 150-200 kWh/m2/year. Renovated old building: approx. 80-120 kWh/m2. New building under EnEV: approx. 40-60 kWh/m2. 5. Identify savings potential: optimise the heating, lower the room temperature (1 degree less saves approx. 6 % of heating costs).
Calculation Example
Single-family house 120 m2, consumption 18,000 kWh/year (= 1,800 m3). Gas price 0.12 EUR/kWh. Consumption costs: 18,000 x 0.12 = 2,160 EUR. Base price: 150 EUR. Total costs: 2,310 EUR/year.
