Charging the median electric car at home in Indiana costs about $61 a month at 17.51 cents per kilowatt-hour — the 31st cheapest of 51 states, and 5 per cent below the national average. Petrol over the same 1,125 miles costs $170, so the saving is $108 a month, $1,300 a year; on the public side 47 registered cars share each fast-charging plug, against 55 in the typical state.
What electricity costs in Indiana
The EIA published residential average for Indiana is 17.51 cents per kWh (June 2026), against a US average of 18.34. That puts Indiana at 31st of 51 states and DC, cheapest first — the dearer half of the country. The Chevrolet Equinox EV FWD sits in the middle of the 36 cars rated here at 31.1 kWh per 100 miles; in Indiana that is $5.45 per 100 miles and $735 over a year, $-3 a month more than the same car would cost at the national average rate.
Against a 27 mpg car at $4.07 a gallon, electricity stops being the cheaper fuel at about 48 cents per kWh. Indiana is below that line by 30.96 cents, so the saving holds at the state-average rate before any overnight tariff is applied. It is an average across every household and every hour of the month: an overnight window beats it, a summer peak does not. The running-cost calculator takes your own tariff instead of the state’s.
Every EPA-rated car, charged at home in Indiana
Efficiency is worth more in Indiana than in most states: $83 a month separates the Lucid Air Pure RWD from the GMC Hummer EV Pickup 3X, and every car in the table still beats the $170 the petrol car burns through.

Every kWh above is measured at the wall. At 17.51 cents the charging losses alone cost the median driver about $6 a month in Indiana — a real line on the bill, and the reason this site does not quote battery-size arithmetic. Four cars have no US rating; they are in kilometres on the national page.
Public fast charging in Indiana
Indiana has 213 public DC fast-charging sites with 1,012 plugs in the federal AFDC station locator (2026-09-16), for 47,200 battery-electric cars registered in the state at the end of 2025.
There are 47 registered EVs for every public fast-charging plug in Indiana, a little below the 55 of the typical state — 21st of 51 states, fewest cars per plug first. Plug supply is roughly keeping pace with the cars here.
30% of the sites in Indiana have a single plug and the state averages 4.8 plugs per site — enough that a busy stop usually has another bay, not enough to count on it off the interstate.
Tesla is the largest network in Indiana with 53% of the plugs (540 of 1,012), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in Indiana
The plug question in Indiana has a clear answer: 76% of the sites carry CCS1, the connector on almost every non-Tesla EV sold in the US, against 28% carrying the Tesla NACS plug. A CCS car has the run of the state; a Tesla is at home on its own network and needs an adapter elsewhere.
| Connector | Sites in Indiana | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 162 | 76% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 59 | 28% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 68 | 32% | Older Nissan Leaf and Mitsubishi only |
68 sites keep a CHAdeMO plug (32%). Useful if you drive an older Leaf in Indiana; irrelevant to everything else on this page, and the count falls every year as sites are refitted.
Public fast charging does not follow the residential rate. At a typical network price of $0.48 per kWh the median car costs $14.93 per 100 miles — 2.7 times what the same miles cost at home in Indiana, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Indiana should read the home column as optimistic by a factor of 2.7 — that multiple, not the state, is what decides whether the sums work. How long each car takes on a fast charger is on its charging page.
Indiana against its neighbours
Kentucky is cheaper than Indiana; Michigan, Ohio, Illinois are dearer. Same car in every row, so the columns are comparable: Indiana is cheaper than 3 of the 4 states it touches.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Kentucky | 14.26 | 8th | $50 | 460 | 45 |
| Indiana | 17.51 | 31st | $61 | 1,012 | 47 |
| Ohio | 19.19 | 33rd | $67 | 1,535 | 61 |
| Illinois | 19.89 | 36th | $70 | 2,891 | 57 |
| Michigan | 22.99 | 39th | $80 | 1,746 | 64 |
How long the charge itself takes does not change with the state, only what it costs: the Volkswagen ID.7 charging time, Ford Mustang Mach-E charging time and BMW i4 charging time are 27, 32 and 28 minutes from 10 to 80 per cent wherever you plug in, and each of those pages runs the same cost arithmetic as this one at the national average rate rather than Indiana’s.
Frequently asked questions
How much does it cost to charge an electric car in Indiana?
About $5.45 per 100 miles at home for the median EPA-rated car, $61 a month at 1,125 miles, using the EIA residential average of 17.51 cents per kWh. The most efficient car here, the Lucid Air Pure RWD, costs $46 a month; the least efficient, the GMC Hummer EV Pickup 3X, $128.
Is it cheaper to charge an EV than to buy petrol in Indiana?
Yes. At 17.51 cents per kWh the median car costs $61 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $108 a month in favour of Indiana, $1,300 a year.
How many fast chargers are there in Indiana?
213 public DC fast-charging sites and 1,012 plugs in the AFDC locator as of 2026-09-16, for 47,200 registered EVs — 47 cars per plug. Level 2 chargers are not counted here; only DC fast.
Can a non-Tesla use a Tesla charger in Indiana?
Where the site is open to other brands, yes, with the right adapter. 59 of the 213 fast-charging sites in Indiana carry the NACS plug (28%) and 162 carry CCS1 (76%), so a CCS car still has the larger of the two networks to fall back on. The plug on each car is listed on its model page.
Which electric car is cheapest to charge in Indiana?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $4.04 per 100 miles and $46 a month in Indiana. Picking it over the GMC Hummer EV Pickup 3X is worth $83 a month here, which is as much as the Indiana rate ever makes efficiency worth; the full efficiency order is the same in every state.
