Step 1
Go to an electronics store and look through their calculator section. You can use any type of calculator for car loan work, but a financial one streamlines the process.
-
Step 2
Look at name brand finance calculators for reliability and a good warranty. Any calculator that can handle interest rates and figure loan lifetimes can work as a car loan finance calculator.
-
Step 3
Get a calculator that fits your budget and needs. You probably don't need a professional finance calculator if you're just trying to find the best car loan. You may be able to find a cheaper solar powered calculator that has the functions you need.
-
Step 4
Try out a demo model of the calculator. If you bring some of your loan information with you, you can practice with real figures. Ask a salesperson to show you how to perform basic functions like the number of months it takes to pay off a loan assuming minimum monthly payments and a fixed interest rate.

Step 5
Consider using an online car loan finance calculator. These calculators are often easier to use because all you need to do is plug in your loan information. There are many sites that offer online calculators, like Cars.com (see Resources below).
