Total ownership cost: fuel, insurance, maintenance, depreciation, financing.
🚗 Depreciation (purchase − resale) is usually the single biggest cost — new cars lose 20-30% in year one. Financing interest, parking, tolls and registration are not included; add them to insurance if significant.
The purchase-minus-resale line typically beats every other cost category — new cars shed 20-30% of value in the first year alone. A 3-year-old used car often halves that loss.
Monthly figures hide usage. Dividing total cost by lifetime kilometers (~$0.30-0.60/km for average cars) is the number to compare against trains, buses, and ride-hailing.
Financing interest, parking, tolls, registration, and fines vary wildly by country and driver — add them to the insurance field if they matter to you. Electric cars: swap fuel for electricity at ~2-3¢/km equivalent.
A $25k car kept 5 years typically costs $40-50k all-in. Running the numbers before buying turns "I can afford the payment" into "I know what this actually costs me."

The Car Cost Calculator lets you figure out car cost calculatorinstantly, without reaching for a spreadsheet or doing the math by hand. Whether you're planning a budget, checking a loan, or working through homework, the tool applies the correct formula behind the scenes and shows the result the moment you enter your numbers.
Unlike a static chart or table, this calculator adapts to your exact inputs. You can adjust any value and see the outcome update in real time, which makes it easy to compare scenarios — for example, "what if the rate were 1% lower?" or "what if I paid an extra $50 a month?"
Common uses: people reach for this tool when they need to find a how much does a car really cost per month, true cost of owning a car calculator, cost per kilometer car ownership, or new vs used car 5 year cost.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
The Car Cost Calculator is based on the following formula:
Monthly cost = Loan payment + Insurance + Fuel + Maintenance + Depreciation + Fees Fuel = ( Miles per month ÷ MPG ) × Price per gallon Depreciation = ( Purchase price − Resale value ) ÷ Months owned Per-mile cost = Monthly cost × 12 ÷ Annual miles (divide miles by 1.609 for per-km)
Variables: Loan payment = Monthly financing cost ($) Insurance = Monthly premium ($) Fuel = Monthly fuel spend ($) Maintenance = Oil changes, tires, and repairs averaged per month ($) Depreciation = Value the car loses per month ($) Fees = Registration and taxes averaged per month ($) Monthly cost = True cost of ownership ($ per month) Per-mile cost = Monthly cost × 12 ÷ annual miles ($ per mile)
The loan payment is only part of what a car really costs. Adding fuel, insurance, upkeep, fees, and depreciation gives the true monthly figure, which divides into an honest per-mile or per-km rate.
Worked example: Step 1: Payment $420, insurance $140, fees $15, maintenance $60, depreciation = (30,000 − 18,000) ÷ 60 months = $200. Step 2: Fuel: 1,000 miles per month ÷ 28 MPG = 35.71 gallons × $3.40 = $121.43. Step 3: Monthly cost = 420 + 140 + 15 + 60 + 200 + 121.43 = $956.43. Step 4: Per-mile = 956.43 × 12 ÷ 12,000 annual miles = $0.96. Result: the car truly costs about $956.43 per month, or $0.96 per mile.
