Use the Appliance Running Cost Calculator
Running cost comes from power use, time used and electricity price. Always-on devices can matter because the hours stack up.
How much does this appliance cost to run?
Estimate appliance running cost from watts, hours and electricity price, with daily and yearly context.
Things to double-check
- Watts are accurate for the appliance mode used.
- Electricity price is entered per kWh.
- Standby use may be different from active use.
Quick checklist
- Find the wattage label or estimate.
- Enter hours used per day.
- Use your electricity price per kWh.
- Compare daily, monthly and yearly cost.
- Check always-on appliances separately.
Common mistakes
- Ignoring time used.
- Using watts as if they were kWh.
- Forgetting devices that run every day.
Why appliance cost is a time problem
A powerful appliance used briefly may cost less than a smaller device running all day. That is why watts and hours must be calculated together.
How to use the estimate
Use the result to decide whether a habit is worth changing. A tiny daily cost can still be meaningful over a year if the device runs often.
What to calculate next
Use the electricity cost calculator for simple one-device checks and the home energy audit planner for a wider room-by-room review.

How to use this page
Pick the link or tool that matches the question you are trying to answer. Use one real example first, then open a related guide or worksheet only if you need more detail.
Keep it simple
You do not need every link on the page. Start with one result, change one important input if you want to compare options, and use the answer to choose your next step.
Useful next places
Decision guides can help when you know the question but not the tool. Number tools is there when you already know the calculation you need.
How to use the answer
Estimate appliance running cost from watts, hours and electricity price, with daily and yearly context. Use the first result as a starting point, then change one important input if you are comparing options. The second answer usually tells you whether the decision is sensitive to price, time, rate, target, deadline or another assumption.
Before relying on the result, check the unit, date range, percentage base and whether the figure is daily, monthly, yearly or total. If the answer will affect a bill, purchase, study target, health routine or official decision, treat it as a planning estimate and verify the important inputs from a reliable source.
