What drives an electric bill in Indiana
Electricity in Indiana averages about 15.5¢/kWh — about 8% below the U.S. average of 16.8¢. Every kilowatt-hour your home uses is billed at that rate, so Indiana's rate sets the baseline for what every appliance costs to run.
The bill is dominated by high-wattage, long-running loads. In Indiana, running central AC works out to about $99/month and an electric water heater around $57/month; electric heat and EV charging land in the same tier. Small electronics barely move the needle by comparison — it's the heating, cooling, and water loads that decide a Indiana bill.
You have two levers. The first is the rate itself — where Indiana allows supplier or plan choice, shopping it can shave the 15.5¢ baseline. The second is usage: trimming hours on the biggest draws saves far more than unplugging phone chargers. Enter any appliance in the calculator to see its exact cost at Indiana's rate.
