- Usage hours per day
- Days used per month
- Electricity tariff (₹ per kWh or unit)
🧮 How to Use the Electricity Expense Calculator
- Enter appliance wattage (e.g. 1000W for a 1kW heater)
- Input daily usage in hours
- Select days of use per month
- Enter your electricity rate (e.g. ₹8 per unit/kWh)
- Click Calculate
📊 You’ll get:
- Monthly units consumed (kWh)
- Cost per appliance
- Total electricity expense
- Annual cost (optional)
🧠 Example:
| Appliance | Power (W) | Hours/Day | Days/Month | Rate (₹/kWh) | Monthly Cost |
|---|---|---|---|---|---|
| Air Conditioner | 1500W | 5 hrs | 30 days | ₹8 | ₹1,800 |
| LED TV | 100W | 4 hrs | 30 days | ₹8 | ₹96 |
