Fuel Economy Calculator
Calculate MPG, L/100 km, fuel use, and driving efficiency.
ProCar Loan Calculator
Estimate vehicle payments, total interest, and financed cost.
EV Charging Time Calculator
Calculate the battery energy change, adjust for charging loss, and divide grid energy by charger power for idealized time.
New Car Ownership Comparison Calculator
Reconcile purchase price, fees, entered financing interest, recurring operation, and resale for two vehicles across the identical ownership horizon.
Fleet Replacement Reserve Calculator
Compound purchase and resale values to the replacement date, net the cohort outlay, grow the existing reserve monthly, and solve the ordinary-annuity sinking-fund payment for...
EV Trip Cost Calculator
Multiply distance by rated consumption, add charging loss, value purchased electricity, and include entered tolls and parking.
Electric Car Usable Range Calculator
Start with rated and usable battery energy, reserve arrival state of charge, and apply separately named temperature and speed range factors before route and charging checks.
New Car Ownership Schedule Calculator
Amortize a new-car financed amount, depreciate vehicle value independently, accumulate operating cost, and reconcile the remaining loan with sale proceeds.
Vehicle Depreciation Calculator
Compare current value with purchase price and annualize the value ratio over the entered vehicle age.
ProNew Car Ownership Cost Calculator
Combine acquisition cash, loan amortization, recurring driving costs, remaining loan payoff, and estimated resale proceeds to calculate a net cost over the selected ownership...
Used Car Ownership Cost Calculator
Separate used-car acquisition, immediate work, recurring operations, repair reserve, financing interest, and resale credit across the exact ownership horizon.
Tire Size Calculator
Calculate tire sidewall height, overall diameter, circumference, and the proportional speedometer effect between two metric tire sizes.
Car Lease vs Buy Calculator
Total lease cash outflow and compare it with financed purchase payments plus down payment less estimated resale value.
Repair Shop Work Order Capacity Calculator
Convert scheduled repair work order resources into productive minutes, gross throughput, first-pass completed capacity, buffered design demand, utilization, staffing hours,...
Fleet Fuel Budget Calculator
Convert planned fleet route stops and average load into total load, whole vehicles or trips, utilization, fleet distance, fuel, driver hours, operating cost, and cost per stop.
New Car Performance Calculator
Combine loaded mass with rated power and torque, then calculate transparent aerodynamic and rolling road-load references at one selected steady speed.
Vehicle Replacement Savings Calculator
Project replacement-price inflation and trade-in depreciation on separate curves, add future sales tax and fees, deduct future trade value, then compare the net cash target...
New Car Fuel Calculator
Split annual distance into city and highway segments, calculate fuel use from each segment's efficiency, and compound only the entered fuel-price assumption across the...
New Car Maintenance Calculator
Translate annual mileage into service counts, tire replacements, scheduled maintenance, and a mileage-based repair reserve over the exact ownership horizon.
Used Car Fuel Cost Projection Calculator
Blend city and highway consumption by entered distance share, then independently compound annual distance and fuel price across the projection.
Repair Shop Bay Profitability Calculator
Convert physical bay capacity into billed hours, recognize labor revenue and only the gross-profit portion of parts sales, subtract technician and shop-supply costs, then test...
Used Car Maintenance Projection Calculator
Project routine maintenance and repair reserve with one explicit annual change, while retaining a separate major-service event and mileage reference.
Vehicle Idling Cost Calculator
Convert planned idling-intensive route stops and average load into total load, whole vehicles or trips, utilization, fleet distance, fuel, driver hours, operating cost, and...

Compare vehicles on the same distance and ownership horizon
Automotive calculators compare vehicle purchase, finance, depreciation, fuel, maintenance, idling, travel, and long-term ownership cost. Some answer a single-trip question, while others model several years of ownership.
Match fuel-price and economy units, and keep monthly, annual, and lifetime costs on a consistent horizon. Traffic, load, weather, driving style, insurance, taxes, maintenance history, and resale value can materially change real expenditure.
For purchase decisions, compare the same ownership period and mileage across vehicles. A lower payment can still produce a higher total cost when financing, depreciation, energy, maintenance, or end value differs.
