Why the cost differs in Indiana

Indiana has the 32nd cheapest residential electricity of the 51 US states and territories we track, at 18.15¢ per kWh against a national average of 18.44¢. That is -1.6% compared with the national figure. Indiana is midway through a coal-to-gas and coal-to-renewables transition, and the capital cost of that changeover is being recovered through successive rate cases, which is why rates have drifted upward from a historically cheap base. Retail service is regulated. The climate gives a genuine dual peak, with cold winters and humid summers both driving load.

For this appliance specifically, the difference works out to a saving of $0.95 a year against what the same electric lawn mower would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $171 a year; in Idaho it would cost $40.57. That spread of $130 is entirely down to location.

That works out to roughly 3.1% of a typical Indiana household's annual electricity bill - modest individually, though appliances in this range add up.

Indiana sits below the national average, so this electric lawn mower costs slightly less to run here than it would for a typical US household. How you use it will move the number far more than where you live.

Retail service in Indiana is regulated, so most households pay a tariff set through state rate cases rather than a shopped rate. The state average is a reasonable proxy, though your utility's specific tariff still varies.

About running a electric lawn mower

Charging a battery mower costs a few cents per session - a fraction of the fuel cost of a gas equivalent. A typical 5Ah battery holds well under a kilowatt-hour, so even weekly mowing across a full season barely registers on a bill.

What actually changes the cost

  • If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.

How we worked this out

The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:

1200W ÷ 1000 × 0.75h = 0.900 kWh/day × 18.15¢ = $0.163 per day

One honest caveat: Indiana’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.

Questions about electric lawn mower running costs

How many watts does a electric lawn mower use?

A typical electric lawn mower draws about 1200 watts while running, with most models falling between 900W and 1800W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.

How much electricity does a electric lawn mower use per day?

At around 0.75 hours of use a day and a 100% duty cycle, that works out to roughly 0.9 kWh per day, or about 27 kWh a month. Your actual figure depends on your usage and model.

Why does the cost differ so much between states?

Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same electric lawn mower, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.

Is it cheaper to run a electric lawn mower at night?

Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
