EV vs Gas Cost by State

This guide helps readers compare the driving cost of electric vehicles and gas cars across U.S. states. It shows how local gas prices and residential electricity rates can change the cost of traveling the same distance. This kind of comparison is useful for commuters, families, car shoppers, and people planning a move. It gives a clearer view of where EV driving is more affordable and where the gap is smaller. Instead of looking at fuel prices alone, readers can understand how state-level energy costs affect day-to-day driving expenses in a practical and easy-to-read format.

Assumptions: Gas car = 30 MPG. EV = 29 kWh/100 miles. Home charging rates.

How to Use This Comparison

1

Start by choosing the state you want to review

Energy costs vary by state, so location plays a big role in the comparison.

2

Look at the gas vehicle driving cost

This shows the estimated amount a gas car may spend to travel a fixed distance.

3

Check the EV driving cost

This shows the estimated electricity cost for driving the same distance.

4

Compare both values side by side

This helps you quickly see which option is cheaper to drive in that state.

5

Review the savings column

This shows how much lower the EV driving cost is compared with the gas vehicle.

6

Compare multiple states if needed

This is helpful for relocation planning, travel research, or broader market analysis.

7

Use the result as a practical benchmark

It gives a useful cost snapshot, but real-world expenses can still vary by vehicle, driving habits, and charging method.

What This Comparison Measures

This comparison measures the estimated cost of driving an electric vehicle and a gas vehicle over the same distance in each state. The goal is to make energy costs easier to compare.

Gas cost by state

Gas prices are different across the country. A state with higher fuel prices will usually show a higher driving cost for gas vehicles.

Electricity cost by state

Electricity rates also change by location. That affects how much it costs to charge an EV at home.

Gas vehicle efficiency (MPG)

Miles per gallon — how many miles a gas vehicle can travel on one gallon of fuel.

EV efficiency (kWh/100 mi)

Kilowatt-hours per 100 miles — how much electricity an EV uses to travel that distance.

Cost for the same distance

Both vehicle types are measured over the same driving distance so the comparison stays fair and easy to understand.

Estimated savings

The difference between the gas driving cost and the EV driving cost. It helps show where EV driving has a stronger cost advantage.

Formula and Logic

The logic is simple. It compares how much energy each vehicle needs to travel the same distance and then matches that energy use with local state prices.

For a gas car, the comparison uses:

  • Fuel efficiency (MPG)
  • Local gas price
Gas driving cost = (100 / MPG) × gas price per gallon

For an EV, it uses:

  • Electricity use (kWh/100 miles)
  • Local electricity rate
EV driving cost = kWh per 100 miles × electricity rate per kWh

EV savings:

EV savings = gas driving cost − EV driving cost

This format works well because it compares equal distance, not different fuel types on their own. That makes the results easier to understand for everyday drivers.

Example Comparisons

Example 1: Lower electricity cost, average gas price

Inputs

Gas price$3.60 per gallon
Electricity rate$0.12 per kWh
Gas vehicle efficiency30 MPG
EV efficiency29 kWh per 100 miles

Result

Gas vehicle cost for 100 miles~$12.00
EV driving cost for 100 miles~$3.48
Estimated EV savings~$8.52

In a state with lower home electricity rates, EV driving can be much cheaper than gas driving.

Example 2: Lower gas price, higher electricity rate

Inputs

Gas price$3.10 per gallon
Electricity rate$0.18 per kWh
Gas vehicle efficiency30 MPG
EV efficiency29 kWh per 100 miles

Result

Gas vehicle cost for 100 miles~$10.33
EV driving cost for 100 miles~$5.22
Estimated EV savings~$5.11

The EV still costs less to drive, but the gap is smaller when electricity is more expensive and gas is less expensive.

Example 3: Less efficient gas vehicle

Inputs

Gas price$3.50 per gallon
Electricity rate$0.15 per kWh
Gas vehicle efficiency22 MPG
EV efficiency29 kWh per 100 miles

Result

Gas vehicle cost for 100 miles~$15.91
EV driving cost for 100 miles~$4.35
Estimated EV savings~$11.56

The lower the gas vehicle's fuel efficiency, the more noticeable the EV cost advantage can become.

Understanding Your Results

The results are easiest to read when you focus on three main numbers.

Gas Driving Cost

Estimated fuel cost for a gas vehicle to travel the set distance.

EV Driving Cost

Estimated electricity cost for an electric vehicle to travel the same distance.

Savings Difference

How much lower the EV cost is than the gas cost.

A wider savings gap means EV driving is much cheaper in that state.

A smaller gap means the cost advantage is still there, but it is less dramatic.

The more miles a person drives, the more meaningful the savings may become over time.

For low-mileage drivers, the monthly difference may feel smaller even if the EV still costs less per distance traveled.

This comparison focuses on energy cost, not every ownership expense. Insurance, maintenance, vehicle price, charging setup, and resale value are separate factors.

Common Mistakes to Avoid

Looking only at gas prices and ignoring electricity rates

Assuming all EVs use the same amount of electricity

Assuming all gas cars get the same MPG

Treating energy cost as the full cost of ownership

Forgetting that public charging can cost more than home charging

Ignoring how weather and traffic affect efficiency

Comparing one state without checking nearby alternatives

Misreading savings as fixed long-term numbers

Frequently Asked Questions

What does EV vs gas cost by state mean?
It means comparing the estimated driving cost of an electric vehicle and a gas vehicle in each state using local energy prices.
Why does the cost change by state?
Because each state has different gas prices and electricity rates. Those local prices affect driving cost.
Is this comparison useful before buying a car?
Yes. It helps car shoppers understand how state energy costs may affect day-to-day vehicle expenses.
Why is distance-based comparison so helpful?
Because it compares both vehicle types over the same travel distance, which makes the cost difference easier to understand.
Is an EV cheaper to drive in every state?
Not always in the same way, but many state comparisons show EVs costing less to drive than gas vehicles.
Does this reflect home charging or public charging?
Most state-based EV cost comparisons are based on residential electricity rates, which usually reflect home charging.
What does kWh per 100 miles mean?
It means how much electricity an EV uses to drive 100 miles.
What does MPG mean?
MPG means miles per gallon. It shows how far a gas vehicle can travel using one gallon of fuel.
Why might my real cost be different from the comparison?
Your actual result may vary based on your vehicle, speed, weather, road conditions, traffic, and charging habits.
Can this help people moving to another state?
Yes. It gives a useful snapshot of how vehicle driving costs may change after relocation.
Does this include maintenance savings?
No. It focuses on energy cost only, not service, repairs, or long-term maintenance.
Why do efficient gas cars narrow the gap?
Because they use less fuel, which lowers the cost difference compared with an EV.
Why do higher electricity rates matter so much?
Because they raise the cost of home charging and reduce the EV savings gap.
Is this useful for commuters?
Yes. Commuters can use it to understand how daily travel costs compare between EV and gas driving.
Can high yearly mileage make a big difference?
Yes. Even modest savings per 100 miles can add up when someone drives a lot each year.
Should I compare more than one vehicle type?
Yes. It helps to compare different gas vehicle MPG ratings and different EV efficiency levels.
Can public charging reduce the savings?
Yes. Frequent public fast charging may cost more than home charging and can reduce overall EV savings.
Is this comparison good for budgeting?
Yes. It is a useful starting point for understanding transportation energy costs.
Does cheaper gas always mean gas is the better choice?
No. The full comparison depends on both gas prices and electricity rates together.
Who benefits most from this kind of comparison?
Commuters, rideshare drivers, delivery drivers, households with multiple vehicles, and people researching lower driving costs.
