1. What is the Running Cost Calculator?

The Running Cost Calculator helps you determine how much it costs to operate electrical appliances in the UK based on their power consumption, usage time, and current electricity rates.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( W \) — Power consumption in watts
• \( h \) — Usage time in hours
• \( Cost/kWh \) — Electricity cost per kilowatt-hour in £

Explanation: The formula converts watts to kilowatts (dividing by 1000), multiplies by usage time to get kWh, then multiplies by the cost per kWh.

3. Importance of Calculating Running Costs

Details: Understanding appliance running costs helps with budgeting, identifying energy-hungry devices, and making informed decisions about energy efficiency.

4. Using the Calculator

Tips:

• Find wattage on appliance labels or specifications
• For multiple devices, calculate each separately and sum the costs
• Default electricity rate is set to UK average (34p/kWh as of 2023)
• For monthly costs, multiply daily usage by 30

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides estimates based on constant power draw. Actual costs may vary with power fluctuations, standby modes, and tariff variations.

Q2: Where can I find my exact electricity rate?
A: Check your energy bill or contact your supplier. Rates vary by tariff, region, and time of use.

Q3: How can I reduce my running costs?
A: Use energy-efficient appliances, reduce usage time, switch to lower tariffs, and consider solar panels or time-of-use strategies.

Q4: Does this include standing charges?
A: No, this calculates consumption costs only. Add your daily standing charge separately for total costs.

Q5: How do I calculate annual running costs?
A: Multiply daily cost by 365, or weekly cost by 52, adjusting for seasonal variations in usage.
