Electricity Bill Calculator

Whether you call it an electricity bill calculator or an energy bill calculator, this free tool estimates your monthly and annual bill from three numbers: your kWh usage, your rate per kWh, and any fixed charge. Enter your own figures from your latest bill, or use the built-in US, UK, Canadian, or Australian averages.

How this is calculated

Your electricity bill has two components: the energy charge (based on what you use) and fixed charges (flat fees regardless of usage).

Monthly Bill = (kWh used × Rate per kWh) + Fixed monthly charge

Example: (899 kWh × $0.1820) + $10.00 = $173.62
Annual Bill = Monthly Bill × 12

Assumptions

  • A single flat rate applies to all usage (no tiers or time-of-use pricing)
  • Fixed charge is constant every month
  • Excludes taxes, fuel adjustment charges, and delivery/distribution fees
  • Annual figure assumes the same usage every month

How to use this electricity bill calculator

You only need three numbers, all printed on your latest statement:

  1. Monthly kWh used — labelled "Total kWh" or "Energy consumed" on your bill. The US average is about 899 kWh a month.
  2. Rate per kWh — your unit price. Pick your country for the current average, or type the exact rate from your bill.
  3. Fixed monthly charge — the service, standing, or meter fee you pay before any usage (typically $5–$20 in the US, or a daily standing charge in the UK).

The calculator multiplies usage by rate, adds the fixed charge, and shows your monthly and annual total instantly — no sign-up, and every figure is editable.

What's included in your electricity bill

Almost every electricity bill in the US, UK, Canada, and Australia is built from two parts — exactly what this energy bill calculator models:

  • The energy (usage) charge — your kWh used × your rate per kWh. This is the part you shrink by using less.
  • The fixed charge — a flat fee (US "service charge", UK "standing charge") you pay no matter what. In the UK this is a daily standing charge (around 57p/day in 2026); in the US it is usually a monthly service fee.

Real bills then add items this estimate deliberately leaves out so the core maths stays clear: sales tax or VAT, delivery and distribution charges, fuel-adjustment riders, and — on some tariffs — tiered or time-of-use pricing where the rate changes with how much, or when, you use power.

Average electricity bill by country (2026)

Typical monthly electricity bill for an average household at each country's 2026 average rate. Your bill depends heavily on where you live — see the full electricity prices by state & region map.

US figure includes a $10 fixed charge; UK includes ~£17/mo standing charge. National averages — your rate, usage and season will vary.

How to lower your electricity bill

Because your energy charge is just usage × rate, every kWh you cut comes straight off the bill. The highest-impact moves:

  • Kill phantom load — devices on standby can add 5–10% to a bill. See what yours costs with the phantom load calculator.
  • Target the biggest users first — heating, cooling, water heating and the fridge dominate. Our study ranks which appliances use the most electricity.
  • Shift usage off-peak if you're on a time-of-use tariff, and switch any remaining bulbs to LED.
  • Nudge the thermostat 1–2°: model the saving with the smart thermostat calculator.

Frequently asked questions

How is my electricity bill calculated?

Your electricity bill = (kWh used × your rate per kWh) + any fixed monthly charge. For example, 899 kWh at $0.1820/kWh is $163.62 of energy, plus a $10 service charge = $173.62 a month. This calculator uses exactly that formula; real bills may add tax, delivery fees, and tiered or time-of-use rates.

What is the average electricity bill?

The average US household uses about 899 kWh a month, which is roughly $174 a month (around $2,100 a year) at the 2026 average rate of 18.2¢/kWh. UK electricity bills average about £76 a month, Canada about C$140, and Australia about A$138 — though all vary widely by region and season.

Is this an energy bill calculator too?

Yes — "electricity bill calculator" and "energy bill calculator" are used interchangeably for estimating the electricity part of your energy bill, which is what this tool does. If your home also uses gas, that is billed separately at a gas unit rate and is not included here.

What is a fixed charge on my electricity bill?

A fixed charge (US "service charge", UK "standing charge") is a flat fee you pay regardless of usage, covering grid maintenance and metering. In the US it is typically $5–$20 a month; in the UK it is a daily standing charge (around 57p/day in 2026).

Where do I find my kWh usage?

Your monthly kWh is printed on your electricity bill, usually labelled "Total kWh used" or "Energy consumed." If you only have an annual figure, divide it by 12. The US average is about 899 kWh a month (EIA).

How much does electricity cost per kWh in 2026?

2026 national averages are about 18.2¢/kWh in the US (EIA), 26.11p/kWh in the UK (Ofgem price cap), 14¢ in Canada (NRCan), and 33¢ in Australia (AER). Rates vary a lot by region — pick your country for the average, or type the exact rate from your bill.

Why does my actual bill differ from this estimate?

This calculator uses a single flat rate. Real bills can include tiered pricing (higher usage costs more per kWh), time-of-use rates, sales tax or VAT, fuel-adjustment charges, and delivery or distribution fees that vary by utility.

How do I lower my electricity bill?

Because the energy charge is simply usage × rate, every kWh you save comes straight off the bill. The biggest wins are switching to LED lighting, cutting phantom/standby load, running high-draw appliances off-peak if you have time-of-use pricing, and nudging your thermostat by 1–2°.

Does this calculator work for the UK, Canada and Australia?

Yes. Choose your country from the dropdown to load the current average rate (UK Ofgem, Canada NRCan, Australia AER) and the correct currency symbol, or type your own unit rate from any country.

Is the electricity bill calculator free?

Completely free, with no sign-up or email required. Every formula is shown and every rate is sourced from official regulators. You are also welcome to embed the calculator on your own website.
