Frequently Asked Questions
How do I calculate my monthly car loan payment?
Use the car loan calculator by entering the vehicle price, down payment, loan term in months, and annual interest rate. The tool applies the standard amortization formula to give you your monthly payment, total interest paid, and total cost of the loan. Comparing different terms helps you balance monthly affordability against total interest.
How fast does a new car depreciate?
A new car typically loses 20-25% of its value in the first year and around 15% each subsequent year. By year five, most vehicles are worth about 40% of their original price. Our car depreciation calculator lets you model this decline based on purchase price, age, and annual mileage to estimate current or future resale value.
How do I calculate fuel cost for a road trip?
Enter the total trip distance, your vehicle's fuel efficiency (MPG or L/100km), and the current fuel price per gallon or liter. The fuel cost calculator divides distance by efficiency and multiplies by price. The road trip calculator adds multi-stop planning and estimated drive time.
Are electric vehicles really cheaper to run than gas cars?
In most cases, yes. Electricity costs per mile are typically 50-70% less than gasoline. Our EV savings calculator compares annual fuel costs, maintenance savings, and purchase price differences to show your break-even point and long-term savings when switching from a gas vehicle to an electric one.
