🔌 What Is an Electricity Cost Calculator?
An Electricity Cost Calculator estimates the cost of running an electrical device by using three key inputs:
Device Power (Watts)
Usage Time (Hours per Day)
Electricity Price (Cost per kWh)
From these values, the calculator determines:
Daily energy usage (kWh)
Daily electricity cost
Monthly electricity cost
Yearly electricity cost
This allows you to see the true long-term cost of any device—not just its purchase price.
⚙️ How the Electricity Cost Calculator Works
The calculation is based on a simple and widely used energy formula:
Energy (kWh) = Power (Watts) × Time (Hours) ÷ 1000
Once the energy usage is calculated, it is multiplied by your local electricity rate to determine the cost.
Example Calculation:
Device power: 1500 W
Usage time: 6 hours/day
Electricity price: $0.15 per kWh
Daily energy usage:
1500 × 6 ÷ 1000 = 9 kWh
Daily cost:
9 × 0.15 = $1.35
Monthly cost:
$1.35 × 30 ≈ $40.50
Yearly cost:
$1.35 × 365 ≈ $492.75
