How to Use the Calculator
- Enter your gas consumption in cubic meters (m³)
- Enter the current gas rate per cubic meter (€/m³)
- Enter the VAT rate (default is 21%)
- Enter your standing charge per month (€)
- Click the "Calculate" button to see your estimated gas bill
Understanding the Calculation
The calculator works based on these simple steps:
- Calculate the energy cost by multiplying your consumption by the gas rate
- Add the standing charge (fixed monthly cost)
- Calculate VAT on the energy cost only (not on the standing charge)
- Add all these values to get your total gas bill
Example
If you consumed 200 m³ of gas at a rate of €0.15/m³, with a standing charge of €15 and VAT at 21%:
- Energy cost: 200 × €0.15 = €30.00
- VAT on energy: €30.00 × 21% = €6.30
- Total bill: €30.00 + €15.00 + €6.30 = €51.30
Note: This calculator provides an estimate based on the inputs. For your actual bill, please refer to your gas provider's official statement.
