Total Savings with Electric Car Over 10 Years:
How savings are calculated: This calculator estimates the total cost of ownership for both a gas and an electric car over your specified period. It sums the initial purchase price, one-time EV costs (charger, tax credits), and annual operating expenses (fuel/electricity, maintenance, insurance) multiplied by the ownership years. The "Total Savings" is the difference between the total gas car cost and the total electric car cost. A positive value indicates savings with an EV, while a negative value (shown in red) indicates a higher cost for the EV.

What is a Gas vs Electric Car Savings Calculator?
A gas vs electric car savings calculator is an essential online tool designed to help prospective car buyers and current vehicle owners understand the financial implications of choosing between a traditional gasoline-powered vehicle and a battery electric vehicle (EV). It provides a side-by-side comparison of the total cost of ownership over a specified period, factoring in various expenses that go beyond the initial purchase price.
This calculator is ideal for anyone considering a new vehicle, especially those weighing the environmental benefits and potential fuel savings of an EV against the familiarity and established infrastructure of a gas car. It helps demystify the long-term financial picture, allowing users to make informed decisions tailored to their driving habits and local costs.
Common Misunderstandings:
- Ignoring Charging Infrastructure Costs: Many overlook the one-time cost of installing a home Level 2 charger, which can significantly impact initial EV expenses.
- Underestimating EV Insurance: While maintenance is often lower for EVs, their higher initial purchase price can sometimes lead to higher insurance premiums.
- Neglecting Tax Credits and Rebates: Federal, state, and local incentives for EVs can drastically reduce the effective purchase price, a factor often missed.
- Static Fuel/Electricity Prices: The calculator provides a snapshot, but real-world prices fluctuate. It's important to use average or anticipated long-term costs.
- Units Confusion: Understanding efficiency in MPG vs. L/100km or Mi/kWh vs. km/kWh is crucial for accurate input. Our tool allows you to switch between unit systems for clarity.
Gas vs Electric Car Savings Formula and Explanation
The core of the gas vs electric car savings calculator lies in comparing the total cost of ownership for each vehicle type. The general formula for total cost of ownership is:
Total Cost (Vehicle) = Purchase Price + (Annual Fuel/Electricity Cost + Annual Maintenance Cost + Annual Insurance Cost) × Ownership Years + One-time EV Costs - EV Rebates
The savings are then simply the difference between the total cost of the gas car and the total cost of the electric car:
Total Savings = Total Cost (Gas Car) - Total Cost (Electric Car)
Variable Explanations:
| Variable | Meaning | Unit (US / Metric) | Typical Range |
|---|---|---|---|
| Purchase Price | Initial cost to buy the vehicle. | Currency / Currency | $25,000 - $80,000+ |
| Fuel Price | Cost of gasoline per gallon or electricity per kWh. | $/gallon / €/liter (gas), $/kWh / €/kWh (elec) | $2.50-$5.00 / gallon; $0.10-$0.30 / kWh |
| Fuel Efficiency | How far the vehicle travels per unit of fuel/energy. | MPG / L/100km (gas); Mi/kWh / km/kWh (elec) | 20-40 MPG; 2.5-4.5 Mi/kWh |
| Annual Driving Distance | Total distance driven in a year. | Miles / Kilometers | 10,000 - 20,000 miles (16,000 - 32,000 km) |
| Annual Maintenance Cost | Yearly expenses for servicing, repairs, etc. | Currency / Currency | Gas: $500-$1000; EV: $300-$700 |
| Annual Insurance Cost | Yearly premium for vehicle insurance. | Currency / Currency | $1,200 - $3,000+ |
| Ownership Years | The duration you plan to own the car. | Years / Years | 5 - 15 years |
| EV Charger Installation Cost | One-time cost for home charging setup. | Currency / Currency | $0 - $2,000 |
| EV Tax Credit / Rebates | Incentives reducing EV purchase price. | Currency / Currency | $0 - $7,500+ |
Practical Examples
Let's look at a couple of scenarios using the gas vs electric car savings calculator to understand how inputs affect the outcome.
Example 1: High Mileage, High Gas Prices (Favoring EV)
Inputs (US Customary):
- Gas Car Price: $30,000
- EV Price: $40,000
- Gas Price: $4.50/gallon
- Electricity Price: $0.12/kWh
- Gas Efficiency: 25 MPG
- EV Efficiency: 3.8 Mi/kWh
- Annual Driving: 18,000 miles
- Ownership: 10 years
- Gas Maintenance: $800/year
- EV Maintenance: $450/year
- Gas Insurance: $1,500/year
- EV Insurance: $1,800/year
- EV Charger: $800
- EV Tax Credit: $7,500
Results: In this scenario, the EV would likely show significant savings. The higher mileage and expensive gas make the EV's lower "fuel" cost highly impactful over a decade. The tax credit further reduces the initial EV cost difference, leading to substantial electric vehicle savings.
Example 2: Low Mileage, Cheap Gas (Favoring Gas Car or Smaller EV Savings)
Inputs (Metric System):
- Gas Car Price: €28,000
- EV Price: €42,000
- Gas Price: €1.60/liter
- Electricity Price: €0.25/kWh
- Gas Efficiency: 7.5 L/100km
- EV Efficiency: 6.0 km/kWh
- Annual Driving: 8,000 km
- Ownership: 7 years
- Gas Maintenance: €700/year
- EV Maintenance: €500/year
- Gas Insurance: €1,300/year
- EV Insurance: €1,600/year
- EV Charger: €1,200
- EV Tax Credit: €3,000
Results: Here, with lower mileage and cheaper gas, coupled with a higher electricity price and a smaller tax credit, the EV's upfront cost difference might not be fully offset by fuel savings over 7 years. The "savings" might be minimal, or the gas car could even be cheaper in total. This highlights the importance of using a detailed car ownership cost calculator.

Key Factors That Affect Gas vs Electric Car Savings
Understanding the variables that influence your gas vs electric car savings calculator results is crucial for accurate planning:
- Initial Purchase Price: EVs often have a higher sticker price, which is the largest single factor. However, this is frequently offset by incentives and lower running costs.
- Fuel/Electricity Costs: Local gas prices and electricity rates are major determinants. High gas prices and low electricity rates strongly favor EVs. This is a primary driver of electric vehicle savings.
- Vehicle Efficiency: A gas car with high MPG or an EV with high Mi/kWh (or km/kWh) will naturally incur lower "fuel" costs.
- Annual Driving Distance: The more you drive, the more significant the impact of fuel/electricity cost differences becomes. High mileage drivers see greater potential for EV cost comparison benefits.
- Government Incentives (Tax Credits/Rebates): These can dramatically reduce the effective purchase price of an EV, making them financially competitive much faster.
- Maintenance Costs: EVs generally have fewer moving parts, leading to lower routine maintenance costs (no oil changes, spark plugs, etc.), which contributes to long-term savings.
- Insurance Premiums: EV insurance can sometimes be higher due to the vehicle's higher initial cost and repair complexity, but this varies greatly by model and insurer.
- Home Charging Infrastructure: The one-time cost of installing a Level 2 charger needs to be factored into the EV's total cost, though this is often offset by convenience and lower public charging dependency.
