How It Works — Energy Formula

This calculator uses the standard IEC energy formula, the same formula used by WAPDA and international energy authorities to calculate electricity consumption:

Energy (kWh) = Power (W) × Quantity × Hours/Day × Days/Month ÷ 1000

Enter each appliance’s wattage (found on its label or manual), quantity, daily usage hours, and days used per month. The calculator instantly shows your consumption and estimated electricity costs at your chosen tariff rate. All data is saved in your browser.

📐 Example: 1.5-Ton AC

Standard 1.5T AC (1500W), 8 hrs/day, 30 days:
= 360 kWh/month
At PKR 35/kWh → PKR 12,600/month

💡 LED vs Incandescent

LED (12W) vs Incandescent (60W), 6 hrs/day, 30 days:
LED: 2.2 kWh | Incan: 10.8 kWh
LED saves 80% — PKR 302/month per bulb.

🔄 Inverter AC Savings

Inverter (900W) vs Standard (1500W), 8 hrs/day:
Saves 144 kWh/month
= PKR 5,040/month | ROI in ~18 months.
