Calculate your electricity bill in seconds — for every country, every currency, every tariff structure.
Electricity bills look different in every country — but the underlying math is universal. Whether you're in Karachi, London, Dubai, or Toronto, your bill comes down to the same core components: energy consumed, fixed fees, taxes, and surcharges. This guide breaks down every line item and teaches you how to estimate your bill accurately anywhere in the world.
A kilowatt-hour (kWh) is the universal unit of electrical energy. One kWh equals the energy consumed by a 1,000-watt appliance running for one hour. Example:
Your electricity meter records the total kWh, and that's the number you're billed on.
Every electricity bill — from any country — follows the same formula:
Total Bill = (Units × Rate) + Fixed Charges + Taxes + Surcharges
| Country | Typical Rate (per kWh) | Notable Feature |
|---|---|---|
| 🇵🇰 Pakistan | PKR 25-45 | Slab-based + FPA + taxes |
| 🇮🇳 India | INR 6-10 | State slabs + fixed charges |
| 🇦🇪 UAE | AED 0.30-0.45 | DEWA/ADDC slabs + fuel surcharge |
| 🇸🇦 Saudi Arabia | SAR 0.18-0.32 | Tiered residential rates |
| 🇺🇸 USA | $0.12-0.25 | State-by-state tiered pricing |
| 🇬🇧 UK | £0.25-0.35 | Standing charge + unit rate + VAT |
| 🇩🇪 Germany | €0.30-0.45 | High taxes & grid fees |
| 🇦🇺 Australia | AUD 0.25-0.40 | State-based tariffs |
Most countries use a slab system where the rate per unit increases as you consume more. For example, in Pakistan:
| Monthly Units | Rate per Unit (Example) |
|---|---|
| 0 – 100 kWh | PKR 18 |
| 101 – 200 kWh | PKR 22 |
| 201 – 300 kWh | PKR 28 |
| 301+ kWh | PKR 35 |
If you consume 250 units in a tiered system, your bill is calculated like this:
Our calculator uses a flat rate for simplicity — but you can enter your average effective rate to match your actual bill.
Suppose a household consumes 320 units in a month. Assume:
Calculation:
A typical US household using 900 kWh per month at $0.15/kWh:
Q: What's the difference between kW and kWh?
A: kW (kilowatt) is power — how much electricity flows at any instant. kWh (kilowatt-hour) is energy — total consumption over time.
Q: Can I use this calculator for any country?
A: Yes. Select your country preset or enter custom rates. The formula is universal.
Q: Why does my bill go up in summer?
A: Air conditioners and fans run longer in hot weather — consumption can double.
Q: Does this include all taxes?
A: It has a tax field and an additional charges field. Enter your tax % and any surcharges to match your bill structure.
Q: Can I use this for commercial buildings?
A: Yes — select "Commercial" as utility type. Rates are usually higher than residential.
Q: Is my data private?
A: Yes — everything runs in your browser. Nothing is uploaded.
