Our Mission
Home Energy Cost Calculator was created with a simple goal: to help households understand exactly how much their electrical appliances cost to run — and to reveal the hidden costs of standby power that silently add up on every energy bill.
With UK energy prices having risen dramatically since 2022, understanding your energy consumption has never been more important. Our free calculator gives you instant, transparent cost breakdowns without requiring any sign-up, personal data, or complicated setup.
Why We Built This
Many people are surprised to learn that leaving devices on standby can cost £50–£100 per year, or that a single appliance like a tumble dryer can add over £100 annually to their electricity bill. We built this tool because:
- Energy bills are confusing — most people don't know how to convert watts into pounds and pence
- Small changes add up — switching off standby devices or reducing usage by even 30 minutes a day can save meaningful amounts over a year
- Knowledge empowers action — once you can see the cost, you can make informed decisions about which appliances to use less, replace, or switch off
How Our Calculator Works
Our calculator uses the standard formula used by energy companies worldwide:
Daily cost = (Watts × Hours used) ÷ 1,000 × Price per kWh
This is the same calculation your energy meter performs. We simply make it accessible and instant, so you can check any appliance in seconds. All calculations run locally in your browser — nothing is sent to any server.
