You can use this calculator to answer the following questions:

  • How much 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?

Related You may also like the Mortgage Calculator. It too accepts six inputs, but it asks for a percentage for the down payment rather than an amount.

This auto loan calculator is not limited to solving car loan problems of course. It can be a useful tool whenever money is borrowed to purchase an item requiring a down payment.

  1. I’m looking for something similar to this – but with interest rate generated automatically (likely based on credit score).

    Is this something you have done or seen?

    • Hi, no, sorry to say, it’s not something I’ve seen. Perhaps it’s available. But even given a specific credit score, the rate would vary from lender to lender, so I imagine a site would have to have connectivity and share data with lenders to auto fill in an interest rate.

  2. Good job.

    Thank you for the site and calculations,
    will be very helpful if you can show the formula on those steps, on how you do weekly, bi-weekly part.

    Thank you

  3. Great calculator, glad i found this. It lets me show my nephew and his wife what happens when you adjust any number…

    • Thank you! I’m happy you found it too. I’m not sure why, but this is one of the least used calculators on this site. It needs some love. 🙂

  4. This would have worked for me if I could enter the date the loan began and the date the payments began. Unfortunately I cannot find a place to enter those things. I tried using the amortization schedule but it will NOT accept weekly payments. Every time I tries to enter the weekly payment it changed it to monthly and the loan cost hundred of thousands of dollars.

    I loved the old program I purchased years ago from you. I wish I could still get it but that computer bit the dust.

    • The amortization schedule does accept weekly payments until you have it set for "Canadian" amortization method. If you do, then please set it to normal and set the compounding to semi-annual and the payment frequency to weekly.
