What this calculator does
The 10-Year Vehicle Ownership Cost Calculator gives you a complete financial picture of owning an electric vehicle (EV), hybrid, or gas-powered car over a decade. Instead of focusing only on the sticker price, this tool factors in everything that affects your wallet: depreciation, fuel or charging costs, insurance premiums, routine maintenance, and the resale value you recoup when you sell.
Most car buyers underestimate the true cost of ownership. A gas car with a lower purchase price can easily cost more than an EV over 10 years when you account for fuel savings, lower maintenance, and federal tax credits. Conversely, a high-end EV in a state with expensive electricity may not deliver the savings you expect. This calculator cuts through the noise and shows you the numbers specific to your location, mileage, and driving style.
What's included in the calculation
The calculator considers five major cost categories for each vehicle type:
- **Purchase price**: The initial out-of-pocket cost, adjusted for applicable incentives like the federal \$7,500 EV tax credit. - **Depreciation**: How much the vehicle loses in value over 10 years. EVs and gas cars depreciate differently — this is factored into the net cost. - **Fuel or charging costs**: Gas vehicles use local fuel prices; EVs use your state's average electricity rate multiplied by your annual mileage and vehicle efficiency. - **Insurance**: Annual premiums vary by vehicle type, state, and driving profile. EVs typically cost slightly more to insure due to repair costs; hybrids are often the cheapest. - **Maintenance**: EVs have no oil changes, fewer brake jobs (regenerative braking), and generally lower long-term maintenance costs. Gas vehicles have higher ongoing service needs. - **Resale value**: What you get back when you sell. This reduces the net cost and is a significant factor — especially for models with strong demand.
EV vs Hybrid vs Gas: Key differences
**Electric Vehicles (EVs)** EVs have a higher upfront purchase price but dramatically lower fuel and maintenance costs. The federal \$7,500 tax credit (for qualifying vehicles and buyers) can offset a significant portion of the price gap. EVs are most cost-effective in states with low electricity rates and high gas prices, and for drivers with high annual mileage who benefit most from fuel savings.
**Hybrids** Hybrids offer a middle ground: better fuel economy than a gas car without the range anxiety or charging infrastructure concerns of a full EV. They typically have lower insurance costs and strong resale values. For drivers who frequently travel long distances or in areas without reliable EV charging, a hybrid often delivers the best balance of savings and convenience.
**Gas Vehicles** Gas cars have the lowest upfront cost and the most mature service infrastructure. They depreciate predictably and are widely understood by mechanics everywhere. However, over 10 years, higher fuel costs and more frequent maintenance (oil changes, transmission service, exhaust repairs) add up. In high-gas-price states, the total cost of ownership can substantially exceed that of an EV or hybrid.
How to use
1. Select which vehicle types you want to compare — EV, Hybrid, Gas, or any combination. 2. Choose your state from the dropdown. This determines local electricity rates, gas prices, and insurance averages. 3. Set your annual mileage using the slider. Higher mileage amplifies the fuel cost differences between vehicle types. 4. Select your driving profile (Mostly City, Mixed, or Mostly Highway). City driving favors EVs due to regenerative braking; highway driving narrows the efficiency gap. 5. Choose your purchase price range to get realistic comparisons within your budget. 6. Click "Calculate 10-Year Costs" and wait 10-30 seconds for the AI to run the analysis. 7. Review the results: the cheapest option, per-vehicle breakdown, full cost table, and key insights.
Understanding depreciation
Depreciation is the single largest cost of vehicle ownership for most people — often exceeding fuel costs over a 10-year period. It represents the difference between what you paid and what the vehicle is worth when you sell.
New vehicles typically lose 15-25% of their value in the first year alone. By year five, most vehicles have lost 40-60% of their original value. The rate slows considerably after that.
EVs have historically depreciated faster than gas vehicles due to battery technology concerns and rapid model updates. However, this trend has been reversing as EV adoption grows and battery reliability improves. Popular models like the Tesla Model 3 and Model Y now hold value comparably to top gas vehicles.
Hybrids, particularly Toyota's lineup, tend to hold value exceptionally well. The Prius, for example, has one of the strongest resale value records in the industry.
This calculator accounts for current depreciation curves by vehicle type and price range, giving you a realistic estimate of residual value at the 10-year mark.
FAQs
Q: Does this calculator include the \$7,500 federal EV tax credit? A: Yes. When the AI analysis is run, it factors in the federal EV tax credit for qualifying vehicles and buyers. The credit effectively reduces the net purchase price of eligible EVs, which significantly improves their 10-year cost comparison against gas vehicles.
Q: Why does location matter for vehicle cost comparison? A: Location affects electricity rates (which determine EV charging costs), gasoline prices, insurance premiums, and state-level EV incentives. For example, California has high gas prices but also substantial state EV rebates, while states like Texas have lower electricity costs but fewer state-level incentives. These differences can shift the comparison by thousands of dollars.
Q: How accurate are these estimates? A: The estimates are based on current market data for your selected state and vehicle category. They represent typical ownership scenarios and should be used for comparison purposes. Your actual costs will vary based on your specific vehicle model, driving habits, local insurance rates, and market conditions at the time of purchase or sale.
Q: Why does annual mileage matter so much? A: Higher mileage amplifies fuel cost differences. An EV driven 20,000 miles per year saves significantly more on fuel than one driven 8,000 miles per year. At low mileage, the upfront price premium of an EV may never be fully offset by fuel savings within a 10-year window. At high mileage, the break-even point can come as early as year 3 or 4.
Q: Should I include maintenance costs in my car budget? A: Absolutely. Maintenance is one of the most commonly overlooked ownership costs. A gas vehicle typically requires oil changes every 5,000-7,500 miles, plus transmission service, spark plug replacement, exhaust repairs, and other interval-based service. Over 10 years, this can total \$8,000-\$15,000 depending on the vehicle. EVs avoid most of these costs but may have higher tire wear and battery-related service needs.
Q: Can I compare just two vehicle types? A: Yes. You can uncheck any vehicle type you do not want to include. The calculator will compare only the selected types and still provide a full breakdown for each.
Q: Is the resale value realistic? A: Resale values are estimated based on current depreciation data for your vehicle category and price range. Electric vehicle resale values have been more volatile than gas vehicles due to rapid technology changes and shifting buyer sentiment, so these estimates carry more uncertainty for EVs than for gas or hybrid vehicles.
