Energy Cost Formula:
From: | To: |
This Energy Calculator, inspired by Martin Lewis, helps you calculate the cost of electricity consumption based on kilowatt-hours (kWh) used and the rate per kWh. It provides a quick and accurate way to estimate your energy expenses.
The calculator uses the simple formula:
Where:
Explanation: The calculation multiplies the amount of electricity used (in kWh) by the unit rate (price per kWh) to determine the total cost.
Details: Understanding your energy costs helps with budgeting, comparing energy tariffs, identifying energy-saving opportunities, and managing household expenses effectively.
Tips: Enter your electricity consumption in kWh and the current rate per kWh in GBP. Both values must be positive numbers. The calculator will provide the total cost in British Pounds.
Q1: Where can I find my kWh usage?
A: Your electricity bill or smart meter display will show your consumption in kilowatt-hours (kWh).
Q2: How do I find my current energy rate?
A: Check your latest energy bill or your energy supplier's website for the current rate per kWh.
Q3: Does this include standing charges?
A: No, this calculator only calculates the cost based on consumption. Standing charges are typically added separately to your bill.
Q4: Can I use this for gas calculations?
A: This calculator is designed for electricity. Gas calculations may require conversion from cubic meters or cubic feet to kWh first.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise based on the inputs provided, but actual bills may include additional charges like VAT, standing charges, or seasonal variations.
