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.
How do I convert cubic metres of gas into kilowatt hours?
Your gas meter measures cubic metres, but you are billed in kWh: kWh = m³ × condition factor (Zustandszahl) × calorific value (Brennwert). Both factors are shown on your gas bill; the calculator is preset to a condition factor of 0.9024 and a calorific value of 11.2 kWh/m³ for H-gas, while L-gas is around 9.8 kWh/m³. 1,500 m³ therefore becomes 15,160 kWh; with a working price of 12 ct/kWh and a base price of 120 euros, that is 1,939.24 euros a year or 161.60 euros a month.
Guide
What is the Gas Consumption Calculator Germany?
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 Germany 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 GEG: 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.
