€456.00

Of €2,000.00 heating costs in the building, you pay €456.00 (22.8%): €336.00 by consumption and €120.00 by floor area.

Consumption costs€336.0074%
Base costs€120.0026%

Consumption costs of the building (70%): €1,400.00
Base costs of the building (30%): €600.00
Your share of total costs: 22.8%

How this was calculated

Consumption = €2,000.00 × 70% × 1,200 / 5,000 = €336.00

Base = €2,000.00 × 30% × 80 / 400 m² = €120.00

The split follows Section 7 of the German Heating Costs Ordinance (50–70% by consumption, the rest by floor area). Hot water is billed separately under Section 8 and is not included here.
