ENERGY COST CALCULATOR

---

The Electrical Cost Calculator is a simple but powerful tool for estimating how much electricity your everyday devices actually use — and what that usage costs you. By entering the wattage, average hours of use per day, and quantity of each device, the calculator instantly shows the daily, monthly, and yearly operating cost. This helps homeowners, renters, and business owners identify which appliances or tools consume the most energy and where savings can be made.

Unlike rough online charts, this calculator lets you enter real-world numbers based on your own habits and electricity rate. You can adjust the cost per kilowatt-hour (kWh) to match your local utility’s rate, add or remove as many devices as you like, and immediately see how each one contributes to your total. It’s ideal for comparing energy-efficient upgrades — for example, swapping halogen bulbs for LEDs or choosing a smaller heater for a workspace.

To use it, simply enter your power rate (usually shown on your utility bill) and fill in each device’s power rating in watts, the number of hours it runs per day, and the quantity you use. The calculator will display each item’s daily energy cost and the overall total for the day, month, and year. You can experiment freely — adjusting hours, wattage, or rate to see how different habits or rates affect your total bill.

Whether you’re trying to cut energy expenses at home, evaluate equipment use on a jobsite, or just understand where your power dollars go, this calculator turns raw data into clear insight. It’s a quick way to see how small changes — a timer, a new bulb, or turning something off for a few hours — can add up to big savings over time.
