Gas heating cost calculator

Estimate gas heating costs based on usage, price and living space.

Inputs

Calculate now

Estimate how much gas heating may cost.

Use the annual consumption from your latest bill or a realistic estimate for your home or apartment.
Enter the unit price from your tariff. Even small price changes can have a strong effect on annual heating cost.
The living area helps you evaluate heating cost per square meter and compare apartments or homes more easily.
The base fee is a fixed cost block and often remains even when consumption falls.
Typical heating systems also create recurring maintenance costs, which matter in the total cost picture.
Use this field for additional fixed charges such as metering, service or smaller recurring costs.
Guidance

Gas heating cost calculator:

Use the result as a scenario comparison, not only as a single number. For energy calculators, runtime, price assumptions, efficiency and seasonal effects usually drive the biggest differences.

How to use the result better

  • Calculate one realistic and one efficient scenario.
  • Compare monthly and annual values so small daily amounts are not underestimated.
  • Check inputs against real tariff, consumption or device data.

Common mistake

The most common mistake is an overly optimistic usage profile: runtimes too short, prices too low or missing base costs.

How exact is the result?

It is a solid estimate when inputs are realistic. Bills may differ because of tariff details, weather, usage and supplier factors.

Why calculate several scenarios?

Scenarios show which input has the strongest impact, and that is usually where optimization should start.

Formula

How the result is calculated

Annual energy cost = annual consumption × price per kWh
Annual fixed cost = base fee + maintenance + other fixed costs
Total annual heating cost = energy cost + fixed cost
Monthly heating cost = total annual heating cost ÷ 12
Heating cost per m² per year = total annual heating cost ÷ living area
Effective cost per kWh = total annual heating cost ÷ annual consumption

Example

Worked example

Example: 14,000 kWh × €0.12 results in €1,680 in pure energy cost. With a €180 base fee, €120 maintenance and €60 in additional fixed cost, total fixed cost comes to €360. This produces total heating cost of €2,040 per year or €170 per month. With 90 m² of living area, that equals about €22.67 per m² per year.

When is this calculator useful?

Use it before switching tariffs, moving home or checking monthly payments.
