The inputs that most influence this result are shown in the breakdown above. Even small changes to key variables can have a significant compound effect over time.
Longer periods amplify both growth and cost. Starting one year earlier or later can change a financial outcome by more than you expect.
Even a 1% change in rate can materially change the outcome over a long period. Use Standard or Advanced mode to model rate sensitivity.
Most financial variables have a non-linear relationship with the result — they compound. The sensitivity table in Advanced mode shows this clearly.
To improve this result, focus on the inputs with the highest leverage. Small changes to the right variable often produce much larger outcomes than large changes to less important ones.
Adjust inputs one at a time. The one that moves the result most is your binding constraint — focus effort there first.
Use the Scenario A/B feature in Advanced mode to compare two situations side by side.
Many financial decisions benefit from timing. Starting earlier, fixing a rate at the right moment, or clearing a debt before applying for new credit can each produce significant improvements.
Depending on what you are planning, these are the natural next steps after reviewing this result.
This calculator shows one part of a financial decision. The related calculators below help you model adjacent factors.

How annual fuel costs are calculated
The fuel cost formula
Annual fuel cost = (Annual miles ÷ MPG) × Fuel price ($/gal). For a car getting 30 MPG, driven 15,000 miles/year at $3.50/gal: (15,000 ÷ 30) × $3.50 = 500 gallons × $3.50 = $1,750/year.
| Annual miles | Fuel economy (MPG) | Price/gal | Annual cost | Weekly cost |
|---|---|---|---|---|
| 12,000 | 35 | $3.50 | $1,200 | $23 |
| 15,000 | 30 | $3.50 | $1,750 | $34 |
| 20,000 | 30 | $3.50 | $2,333 | $45 |
| 15,000 | 25 | $3.50 | $2,100 | $40 |
| 20,000 | 18 | $4.00 | $4,444 | $85 |
Fuel cost examples by vehicle type — United States 2026
Based on average fuel prices of $3.50–$3.80/gal for regular gasoline and $4.00–$4.30/gal for diesel in 2026.
| Vehicle type | Typical MPG | 15,000 mi/year cost | 20,000 mi/year cost |
|---|---|---|---|
| Small car (e.g. Toyota Corolla) | 32–40 | $1,313–$1,641 | $1,750–$2,188 |
| Midsize sedan (e.g. Toyota Camry) | 28–34 | $1,544–$1,875 | $2,059–$2,500 |
| Midsize SUV (e.g. RAV4 gas) | 24–29 | $1,810–$2,188 | $2,414–$2,917 |
| Full-size SUV/pickup truck | 16–20 | $2,625–$3,281 | $3,500–$4,375 |
| Hybrid (e.g. Prius) | 48–56 | $938–$1,094 | $1,250–$1,458 |
| EV (e.g. Tesla Model 3) | 25–30 kWh/100mi | $600–$720* | $800–$960* |
*EV cost at $0.16/kWh home charging rate. Public DC fast charging is 2–3× more expensive.
Electric vehicle vs gas — true running cost comparison
Energy cost comparison
A gas car getting 25 MPG at $3.50/gal costs $1,400 per 10,000 miles. An EV using 30 kWh/100mi at $0.16/kWh (home charging) costs $480 per 10,000 miles — a 66% saving. At public DC fast-charger rates ($0.40–$0.60/kWh), that running-cost advantage shrinks sharply or disappears entirely, so home charging is where EV economics are won.
Total cost of ownership
EVs have lower running costs (fuel, servicing) but usually higher purchase prices. The break-even point depends on the price premium and annual miles. For a $10,000-premium EV: at $1,000/year fuel saving, payback is about 10 years; at $2,000/year saving (high-mileage driver), payback is about 5 years. Falling EV prices and the federal tax credit are narrowing this gap.
US EV incentives
The federal Clean Vehicle Credit (IRS) is worth up to $7,500 on eligible new EVs, subject to final-assembly, battery-sourcing, MSRP caps ($55,000 cars / $80,000 SUVs & trucks), and buyer income limits ($150,000 single / $300,000 joint). A separate credit of up to $4,000 applies to qualifying used EVs. Many states add rebates or reduced registration fees, and utilities often offer discounted off-peak EV charging rates — check your state and utility for current programs.
How to reduce your fuel bill — practical strategies
Driving habits (save 10–20%)
Smooth acceleration and braking, maintaining a steady speed on the highway, reducing highway speed by 5–10 mph (saves roughly 10% of fuel), avoiding idling for more than 30 seconds, and keeping tires inflated to the recommended pressure.
Vehicle choice (save 30–60%)
Switching from a 25 MPG SUV to a 50 MPG hybrid saves approximately $1,050/year at 15,000 miles ($2,100 vs $1,050). Fuel economy varies more between models than between brands — check the EPA's official ratings at fueleconomy.gov before you buy.
Using gas price apps
Gas prices tend to rise ahead of weekends and holidays and dip mid-week. Warehouse clubs (Costco, Sam's Club) and some grocery-branded stations are frequently 10–20¢/gal cheaper than the corner station. Apps like GasBuddy, AAA, Waze, and Upside show real-time prices across nearby stations.
True cost of commuting by car vs public transport
Full cost of car commuting
Fuel is only one cost of driving. The full cost per mile includes fuel, depreciation, insurance, registration, maintenance, and parking. The IRS's 2026 standard mileage rate is 72.5 cents/mile for business use — a reasonable proxy for the all-in cost of running a car. (Note: your regular home-to-work commute is not tax-deductible.)
| Commute distance (one way) | Fuel only (25 MPG) | Full cost (72.5¢/mi) | Commuter type |
|---|---|---|---|
| 10 mi each way | $700/year | $3,625/year | Short commute |
| 20 mi each way | $1,400/year | $7,250/year | Typical suburban commuter |
| 30 mi each way | $2,100/year | $10,875/year | Long-distance commuter |
Assumes about 250 commuting days a year (round trips). A 20-mile-each-way commute is roughly 10,000 miles/year.
Public transit comparison
A monthly transit pass in a major US city runs about $70–$130/month ($840–$1,560/year). An equivalent 20-mile-each-way car commute at full cost is $7,250/year. The car-to-transit saving is roughly $5,700–$6,400/year — before parking.
Frequently asked Frequently asked questions
How is annual fuel cost calculated?
Annual fuel cost = (Annual miles ÷ MPG) × price per gallon. For 15,000 miles/year in a car getting 30 MPG at $3.50/gal: (15,000 ÷ 30) × $3.50 = 500 gallons × $3.50 = $1,750.
What is the average fuel economy of a US car?
The average new car sold in the United States gets roughly 28–34 MPG on a combined EPA cycle. Full-size SUVs and pickup trucks typically get 16–20 MPG. Hybrids average 45–55 MPG. EVs are measured in kWh per 100 miles (typically 25–35 kWh/100mi).
How much does an EV cost to run compared to gas?
At home charging rates of $0.12–$0.20/kWh, an EV typically costs $360–$600 per 10,000 miles versus about $1,200–$1,600 for a 25–30 MPG gas car — a saving of roughly 55–70%. Public DC fast charging ($0.40–$0.60/kWh) is 2–3× home rates and can erase the savings.
Can I deduct car costs on my taxes?
If you use your car for business (not your regular home-to-work commute), you can deduct vehicle costs using either the IRS standard mileage rate (72.5 cents/mile for 2026) or the actual-expense method (gas, depreciation, insurance, repairs, prorated to your business-use percentage). The self-employed claim this on Schedule C; keep a contemporaneous mileage log either way.
What is the cheapest day to buy gas in the United States?
There's no strict national cycle, but gas prices commonly rise ahead of weekends and holidays and ease mid-week. Warehouse clubs (Costco, Sam's Club) and grocery-branded stations are often 10–20¢/gal cheaper. Use apps like GasBuddy, AAA, Waze, or Upside to find the cheapest station near you.
