About Auto & Transport Calculators

These tools break a car's real cost into the numbers you actually decide on: not just the sticker price, but what you'll spend to drive, fuel, register, and eventually replace it. They're built for anyone weighing a purchase, a lease, a longer commute, or a switch to electric, where small per-mile differences compound into thousands of dollars a year.

Run the Car Payment Affordability Calculator before you visit a dealer to see what monthly payment fits your income, and the Lease vs Buy Car Calculator when you're torn between lower payments and long-term ownership. The Fuel Cost Calculator and MPG Calculator translate gas prices and efficiency into a per-trip number, while the Commute Cost Calculator shows what a job change or move does to your yearly driving budget.

Use the EV vs Gas Savings Calculator when an electric model's higher price has to be justified by lower running costs and any federal clean-vehicle credit administered by the IRS. The Car Depreciation Calculator estimates resale value and trade-in timing, and the Vehicle Registration Fee Estimator reflects that title and plate fees are set by each state's DMV, not the federal government.

Frequently Asked Questions

Is leasing or buying a car cheaper in the long run?
Leasing usually means lower monthly payments but no ownership, so over many years buying and keeping the car is typically cheaper because the payments end while the vehicle still has value. Leasing can make sense if you want a new car every few years, drive under the mileage cap, and value predictable costs over equity. The Lease vs Buy Car Calculator compares total out-of-pocket cost across the period you actually plan to keep the vehicle.
How much car payment can I afford on my income?
A widely used guideline keeps total monthly auto costs, including the payment, insurance, and fuel, under about 15 to 20 percent of your take-home pay, with a down payment of roughly 20 percent on a new car. Lenders also look at your overall debt-to-income ratio, so an affordable payment depends on your rent or mortgage and other loans, not the car alone. The Car Payment Affordability Calculator works backward from your income to a target payment and loan amount.
Does buying an electric car still save money compared to gas?
The math depends on your local electricity rate versus gas prices, how many miles you drive, and whether the model qualifies for the federal clean-vehicle credit, which the IRS ties to assembly location, battery sourcing, and buyer income limits. EVs generally cost less per mile to fuel and need less routine maintenance, but a higher purchase price and home-charging setup can offset that for low-mileage drivers. Confirm current credit eligibility on the IRS website, since the rules and qualifying-vehicle list change.
Why are vehicle registration fees so different from state to state?
Registration, title, and plate fees are set by each state's Department of Motor Vehicles, not by any federal agency, so the same car can cost very differently to register depending on where you live. Some states charge a flat fee, while others base it on the vehicle's value, weight, age, or a combination, and a few add a personal property tax at renewal. The Vehicle Registration Fee Estimator gives a ballpark, but your state DMV is the authoritative source for the exact amount.
How fast does a new car lose value?
A new vehicle commonly loses a large share of its value in the first year and continues depreciating each year after, with most of the drop happening in the first three to five years of ownership. Actual rates vary widely by brand, model demand, mileage, and condition, so a reliable model can hold value far better than the average. The Car Depreciation Calculator estimates resale value over time, which helps with timing a trade-in and avoiding owing more on a loan than the car is worth.
