How is the running cost calculated?

Watts ÷ 1,000 × the electricity rate gives cost per hour; the yearly figure uses 0.15 h/day, 365 days a year at 2,400 W.

Does a higher star rating cut the cost?

Yes — efficiency ratings reduce the draw or energy per use, which scales the cost directly; the low–high wattage band spans efficient to inefficient models.

Why does the state matter?

Each state's usage rate differs, so the same hour costs $0.66–$1.01 depending on the state.

At typical draw · official state tariffs

$0.66–$1.01 per hour at 2,400 W

Typical household use — 0.15 h/day, 365 days a year at 2,400 W — runs $36–$55 a year depending on your state's tariff.

Wattage basis: Standard 1.7 L household kettles rate 2,200–2,400 W; travel kettles 1,000–1,500 W; high-performance up to 3,000 W.

Cutting the cost

Only boil what you'll actually pour. A kettle filled to the brim wastes most of its heat warming water you'll tip away, so fill it from the cup you're about to use. Descale it now and then, since scale on the element slows the boil. And an electric kettle heats water more efficiently than a pot on the cooktop.

Frequently asked questions

How is the running cost calculated?: Watts ÷ 1,000 × your electricity rate = cost per hour. A kettle drawing 2,400 W on a 33.1c/kWh tariff costs $0.80 an hour — the calculator above lets you change every input.
Does a higher star rating cut the cost?: Yes — the star rating compresses the power draw or energy per use, which scales this page's figures directly. The low–high band in the table (1,000–3,000 W) roughly spans efficient to inefficient models.
Why does the state matter?: The appliance draws the same power everywhere — but each state's reference usage rate differs, so the same hour of running costs $0.66 in the cheapest state and $1.01 in the dearest. Pick your state above for exact figures.
