7 Free Car Comparison Spreadsheets for Buying Your Next Car

Here are 7 free car comparison spreadsheet templates to help you compare prices, features, and buying strategies.

Buying a car is equally exciting and stressful.

Exciting, because after all, you’re getting a car that’s new to you. Freedom! Mobility! Independence!

Stressful, because buying a car is complicated. Should you lease or buy? Are you paying too much? Or are you paying too little, and getting a car that will need expensive attention down the road? And does it ever make sense to buy a cheap car with high miles or known issues?

Also, buying a new car has never been more expensive. And as CarDealershipGuy mentions in this interview, prices are unlikely to drop to pre-pandemic levels, because “new vehicle production costs have risen significantly since 2020. The prior price baselines no longer reflect reality…. Prices absolutely WILL decline, but it’s very unlikely that we’ll get back to pre-2020 levels.”

With high prices and endless options, it’s essential to stay organized and focused on the factors that matter most to you.

To help you navigate this process, here are free car comparison spreadsheet templates designed to compare prices, and features, and understand the value of your current car as a trade-in or sale.

About the 20/4/10 Rule for Buying a Car

Buy a car spreadsheet

If you’re going to use a loan to buy your car, the 20/4/10 guideline helps you budget for what you can afford. It recommends making a 20% down payment on a car, taking out a loan for a four-year period, and keeping your total transportation costs under 10% of your monthly income.

This rule is designed to help you buy a car that you can afford to pay for and maintain comfortably with less risk. Here’s how the 20/4/10 rule works:

  • 20% down payment. A 20% down payment means you’ll have to pay 20% of the purchase price of the car upfront before you can even take it home. It’s important to remember that a down payment will reduce the amount of money you’ll have to borrow, and it will also make your monthly car payments lower.
  • 4-year loan. A 4-year loan is a good option for most people. It’s long enough to give you time to pay off the loan, but not so long that you’ll end up paying a lot of interest.
  • Budget 10% of your income for transportation. This includes your car loan payment, insurance, gas, and any other expenses related to your car. If you keep your transportation costs under 10% of your monthly income, you’ll be in a good position to afford your car.

Of course, the 20/4/10 rule is just a guideline. There may be times when it’s not possible to follow this rule, or when it doesn’t make sense for you to do so. But if you can, following the 20/4/10 rule will help you buy a car that you can afford and that will meet your needs.
