Monthly Cost (€):

Where Rate is €0.25/kWh for standard tariff or €0.15/kWh for economy 7 tariff (day rate)

This formula provides a simple estimate. Actual costs may vary based on your specific electricity plan and usage patterns.

Worked Examples

Example 1: Standard Tariff

If you use 15 kWh per day on a standard tariff:

Monthly consumption: (15 × 30) / 30 = 15 kWh
Monthly cost: 15 × €0.25 = €3.75

Example 2: Economy 7 Tariff

If you use 10 kWh per day on an economy 7 tariff:

Monthly consumption: (10 × 30) / 30 = 10 kWh
Monthly cost: 10 × €0.15 = €1.50

Note: Economy 7 tariffs typically have higher night rates, but this calculator uses the day rate for simplicity.
