Details: Accurate electricity cost estimation is crucial for budgeting, comparing energy tariffs, identifying energy-saving opportunities, and managing household or business expenses effectively.
Tips: Enter your energy consumption in kWh, electricity rate in GBP per kWh, and daily standing charge in GBP. All values must be non-negative numbers.
Q1: What is a standing charge?
A: A standing charge is a fixed daily amount you pay to your energy supplier for being connected to the electricity network, regardless of how much energy you use.

Q4: Can I use this for business electricity?
A: Yes, the same formula applies, though business tariffs may have different rate structures and additional charges.
Q5: How accurate is this calculation?
A: This provides a good estimate for standard tariffs. For precise calculations, refer to your actual energy bill which may include tiered pricing or time-of-use rates.
