VERY IMPORTANT - You must enter a 0 if you want a value calculated. A few users have wondered why this is. They want to know why the calculator does not just recalculate the last calculation if they change one of the inputs such as the amount of the loan.

The calculator operates this way so you can create a payment schedule using whatever inputs you want to use. This behavior is a feature! By not automatically recalculating a payment, this calculator lets those users that do not have a "typical" auto loan create an amortization schedule.

ABOUT DATES - This calculator now allows irregular length first periods. That is, the calculator calculates the exact amount of interest due even when the initial period is shorter or longer than the other scheduled periods. This will result in payment amounts as well as interest charges that do not match other calculators. If you want to match other calculators, then set the "Loan Date" and "1st Payment Date" so that the time between them equals one full period as set in "Payment Frequency." Example: If the "Loan Date" is May 15th and the "Payment Frequency" is "Monthly," then the "1st Payment Date" should be set to June 15th, that is IF you want a conventional interest calculation. See the end of the "Help" text for some more details.

Of course, you can always leave the dates set as they are when the calculator loads.

Auto Loan Amortization with a Difference


Don't let this page's introduction mislead you.

When designing this auto loan amortization calculator, my objective was to create a calculator that would give you, the user, the ability to estimate the total cost of ownership.

The cost of financing is only part of the story.

To get a complete picture, one has to also consider sales tax, insurance, maintenance, periodic registration fees as well as possible loan application fees. This calculator will account for all these potential costs.

You can use this calculator to answer the following questions:

  • What price car can I afford?
  • How much will my car payment be?
  • What car loan rate do I need?
  • How much to put down on a car?
  • How many months to finance a car?
  • NEW - how much will extra payments save in interest?

  • I love the Auto Loan Calculator! However when I enter the URL it takes me to the comment page instead of the calculator. I have even tried copying and pasting the Specialized URL link directly to my desktop, but the link will intermittently return me to the calculator, but usually the discussion instead. Could you send me a download of the calculator program for my PC? Thank you in advance for your time.

    • Hello, financial-calculators.com is back up and running. I’m sorry for the problems you experienced. An automatically applied update went wrong and it eventually brought down the entier site on Tuesday. Unfortunately, I could not figure out the problem and get it fixed until late Tuesday (eastern time USA). Thank you for reporting the problem.

  • I am wanting to use auto loan calculator. I see where I can put our processing fee. When I add the fee, it puts -$ amount under one of the following, trade-in, down pmt. Am I doing something wrong. Thank you for this calculator.

    • Are you saying that you enter a fee in "Loan Fees or Charges" on the "Options" tab and it becomes part of the "down payment" or "trade-in value"? That should not be and it does not happen for me.

      Please try again, and after you click calc, copy and paste to a reply to this comment, the text in the custom URL box found below the calculator. This will give me your inputs and settings so that I can test.

      The only place you should see the fee is in the APR calculation results at the bottom of the schedule if you choose that option as well


      • Lisa Russell says:

        Under loan fee and charges im wanting to put 100$ but when i do it does not calculate it into the total cost.

        • I see what you mean. I have to see what went wrong. I’ll try to release a fix over the weekend. Thanks for taking the time to let me know.

        • Lisa, the problem with the loan fee is fixed. If there is a fee, the calculator will show the customized schedule for auto loans which includes the fee amount. (It always was included on the front of the calculator itself in the total price calculation.)

          You may have to perform a hard refresh of the page if you don’t see the change right away:

          Depending on your operating system all you need to do is the following key combination:

          • Windows: ctrl + F5
          • Mac/Apple: Apple + R or command + R
          • Linux: F5

          Above, from Refresh Your Cache.

          Thank you for reporting the bug. I’m curious, is this calculation a one off for you, or will you be using the calculator regularly, perhaps for business?
