How to Estimate Your Electricity Bill
· 5 min read
Turn watts and hours into units, find your real rate per unit from your bill, and see which appliances matter most in a Pakistani home.
Units are kilowatt-hours
Your meter counts units, and one unit is one kilowatt-hour: 1,000 watts for one hour. So units = watts × hours ÷ 1,000.
Find your real rate per unit
Tariffs change and depend on your slab, so don't rely on a number you read online. Take your latest bill, divide the total payable by the units consumed, and use that all-in rate in calculators.
What uses the most
- Air conditioners — a 1.5 ton non-inverter AC running 8 hours a day can use around 400 units a month.
- Water pumps, irons and kettles — high wattage, but short use.
- Fridges and freezers — modest wattage, but they run all day.
- Fans and lights — small individually, but there are many of them for long hours.
Quick wins
- Set ACs to 26 °C and clean filters regularly.
- Replace old ceiling fans with DC inverter fans.
- Watch the slab thresholds — a few extra units can raise the rate on the whole bill.
