Example Calculation
You want to compare fuel costs for a car that gets 28 MPG over 15,000 miles per year at $3.50 per gallon.
Step-by-step calculation
- 1
Annual miles = 15,000 - 2
MPG = 28 - 3
Price per gallon = $3.50 - 4
Gallons per year = 15,000 ÷ 28 = 535.7 gallons - 5
Annual fuel cost = 535.7 × $3.50 = $1,875 - 6
Monthly fuel cost = $1,875 ÷ 12 = $156.25
Result: At 28 MPG, driving 15,000 miles per year costs about $1,875 in fuel, or roughly $156 per month. If a more efficient car gets 35 MPG, the annual cost drops to $1,500 — a $375 yearly savings.

Common Mistakes to Avoid
Not including the opportunity cost of a down payment when comparing leasing versus buying
Forgetting to factor in the cost of consumables like tires, brakes, and wiper blades that need periodic replacement
Underestimating repair costs for older vehicles, which tend to increase non-linearly as mileage accumulates
Using the manufacturer's towing capacity without accounting for payload, passengers, and cargo that reduce the available towing margin
Not considering resale value when calculating the total cost of ownership for different vehicle options
Frequently Asked Questions
Pro Tips for Better Results
Calculate your annual mileage accurately before estimating fuel and maintenance costs — most people underestimate their actual driving distance
When comparing loan terms, look at total interest paid, not just monthly payments — a longer term lowers payments but dramatically increases total cost
Use the calculator to evaluate whether an extended warranty is worth the cost based on your vehicle's expected repair history
Factor in the cost of accessories, taxes, and registration when budgeting for a vehicle purchase — these can add 10-15% to the sticker price
When calculating fuel costs for a road trip, add a 10% buffer for detours, traffic, and idling that reduce real-world efficiency below calculated values
