Plan a vehicle purchase or trip with free automotive calculators. Work out a car loan payment, trip fuel cost, lease payment, depreciation, or EV charging time, range, and energy cost — formulas shown on every page.
The auto loan calculator uses the standard amortizing-loan formula for monthly payment from vehicle price, down payment, trade-in, APR, and term. It is principal and interest only — add tax, title, and fees separately.
Fuel cost uses distance, efficiency, and price. Units follow the selected currency (mpg or L/100km). Match the numbers you enter to the units shown beside each field.
The EV suite estimates charging time and cost, range, monthly energy cost, battery kWh and C-rate, home and solar charging, charger sizing, and operational CO₂ versus petrol (2.31 kg CO₂/L petrol).
