Electric vs Gas Car Savings Calculator

Electric vs Gas Car Savings Calculator: Which Is Cheaper to Own?

The electric vehicle revolution is here, but is it actually cheaper than a traditional gasoline car? The answer isn’t as simple as comparing sticker prices. You must consider fuel costs, maintenance, tax credits, and—crucially—resale value. Our Electric vs Gas Car Savings Calculator does all that and more. It calculates the total cost of ownership for both types of vehicles over any period, adjusts for inflation on fuel and energy prices, and even shows you the exact year when the EV becomes the cheaper option. This is the tool you need to make a smart, data-driven decision.

Why You Need This Calculator

Buying an electric car often costs more upfront, but lower running costs can make it cheaper over time. However, the math depends on your mileage, local electricity and gas prices, maintenance requirements, and how well each car holds its value. Many people make the switch without realizing they might actually lose money if they don’t drive enough. This calculator gives you the complete financial picture in seconds.

How the Calculator Works

You enter:

• Annual Mileage – how many miles you drive per year.
• Gas Car Purchase Price – the negotiated price.
• EV Purchase Price – the negotiated price.
• Gas Car Fuel Economy (MPG) – miles per gallon.
• EV Efficiency (kWh per mile) – typically 0.25–0.35.
• Gas Price per Gallon – current average or your local price.
• Electricity Price per kWh – your utility rate.
• Ownership Period (Years) – how long you plan to keep the car.
• Annual Gas Maintenance – oil changes, filters, etc.
• Annual EV Maintenance – typically lower.
• EV Tax Credit – any federal or state incentive.
• Gas Car Resale Value (%) – expected value after the period.
• EV Resale Value (%) – expected value after the period.
• Fuel/Energy Inflation (%) – assumed annual increase in prices.

The calculator then computes:

• Annual fuel/energy cost for both cars (Year 1).
• Total cost over the period for both cars, including maintenance, tax credit, and subtracting resale value.
• Net savings – whether the EV saves you money or the gas car does.
• Break-even year – the exact year when the EV’s total cost falls below the gas car’s.

Example: Sarah’s Commute

Sarah drives 15,000 miles a year. She’s comparing a gas SUV ($35,000, 25 MPG, maintenance $1,200/year, resale 45%) and an electric SUV ($45,000, 0.28 kWh/mile, maintenance $700/year, resale 50%, tax credit $7,500). Gas is $3.50/gal, electricity $0.13/kWh. She plans to keep the car for 6 years, and assumes 2.5% annual energy price inflation.

• Gas annual fuel (Year 1): (15,000 / 25) × 3.50 = $2,100
• EV annual electricity (Year 1): 15,000 × 0.28 × 0.13 = $546
• Gas total cost (6 years, incl. resale): $35,000 + (2,100 + 1,200) × 6 (inflated) – 35,000×0.45 ≈ $44,800
• EV total cost (6 years, incl. resale): $45,000 – 7,500 + (546 + 700) × 6 (inflated) – 45,000×0.50 ≈ $39,300
• Savings with EV: $5,500
• Break-even year: The EV becomes cheaper in Year 4.

Sarah discovers that despite the $10,000 higher price tag, the EV will save her over $5,000 over 6 years. The calculator gives her the confidence to go electric.

Real-World Case Study: Mike’s Truck vs. Tesla

Mike drives a pickup truck 20,000 miles a year. He’s considering switching to an electric pickup. Here’s his data:

• Gas truck: $50,000, 18 MPG, maintenance $1,500/year, resale 40%
• EV truck: $55,000, 0.30 kWh/mile, maintenance $800/year, resale 50%, tax credit $7,500
• Fuel prices: Gas $3.80/gal, Electricity $0.15/kWh
• Period: 8 years, inflation 3%

Using our calculator, Mike finds:

• Gas annual fuel: (20,000/18)×3.80 = $4,222
• EV annual electricity: 20,000×0.30×0.15 = $900
• Gas total cost: $50,000 + (4,222+1,500)×8 (inflated) – 20,000 = $87,200
• EV total cost: $55,000 – 7,500 + (900+800)×8 (inflated) – 27,500 = $65,600
• Savings with EV: $21,600
• Break-even: Year 2

Mike is shocked at the massive savings. The calculator made it clear that the EV is a no-brainer for his high-mileage usage.

The Impact of Resale Value

Resale value is a critical factor often overlooked. Some electric cars hold their value better than gas cars, especially with recent battery technology improvements. Our calculator lets you input separate resale percentages, so you can use real data from Edmunds or Kelley Blue Book for your specific models.

Why Inflation Matters

Fuel and electricity prices don’t stay constant. Gas prices can fluctuate wildly, while electricity rates tend to rise slowly. Our calculator lets you set an annual inflation rate for energy costs. This ensures that long-term projections are realistic. For example, if gas prices rise faster than electricity, the EV becomes even more attractive.

How to Use This Calculator for Smart EV Shopping

Advanced Features

Inflation Adjustment

Our calculator applies the same inflation rate to both fuel and energy costs, but you can change it to simulate different scenarios. If you expect gas prices to spike, increase the inflation rate to see how it affects the comparison.

Resale Value Input

We added separate fields for resale value percentages for both vehicles. Use your research or the vehicle’s projected residual value from leasing companies.

Break-Even Year

This is the most powerful feature. It tells you exactly when the EV becomes financially better than the gas car. If the break-even year is after your intended ownership period, the EV might not be worth it.
