What is Time Value of Money?

Time Value of Money (TVM) is the concept that the value of money itself changes over time. Having a dollar today is worth more than a dollar tomorrow. Solving for present value, future value, amount, interest rate and term are some common time value of money calculations. The above online Ultimate Financial Calculator is capable of performing any of these calculations with regular or irregular amounts on any date for savings or loan cash flows.

  1. Hey Karl,

    Just wanted to say Thanks! The attorney for the person doing an owner finance mortgage for me used your site to give me an amortization schedule, and now I have used it to print a schedule for the extra payments I plan to make. The tutorial for setting up the schedule was very easy to follow. I appreciate the use of your site!

  2. Thank you! Is this at all available as an excel template?

    • You’re welcome.

      It’s not. One of the features I’m thinking about adding is the ability to export the schedule to Excel. Would that help?

      In the meantime, it is possible to select the schedule in the print preview and copy/paste to Excel. If you try it, you’ll probably need to do a Paste Special in Excel and paste without the formatting. (Generally works best with IE.)

      • Hi Karl,

        This is a great resource for my financing business. Thank you!

        I had a hard time finding something that accounts for the delay in 1st payment over the loan date.

        If you do a template/export option, it would be even more appreciated.

        Thanks again!

        Daniel

        • Thank you. Setting loan date and first payment date separately is a popular feature.

          I’m thinking about adding an export to Excel feature. But I have a lot of other items on the list to do first. In the meantime, it is possible to copy/paste to Excel (if that’s helpful) from the print preview window. You will most like have to use Excel’s "Paste Special&quote feature without formatting. But each value will be in it’s own cell. From there, you can add back in any formatting you like.

  3. Karl,
    Your amortization schedule is wonderful.
    I am a business law and real estate attorney . I have been practicing for 50 years.
    I just came across your financial calculator web site. Where has it been for the last 50 years?
    Oh yea, computers and software were in their infancy.
    It is now in my “favorites” category.

    Peter Abbo

    • Well, thank you! I appreciate the nice words. As you noted, I wouldn’t have been able to help you out 50 years ago, but I did write my first calculator in March 1983 (for an Apple IIe), and I’ve just not been able to stop. 🙂

      Please tell your colleagues about this site. I could use the traffic for bragging rights.

  4. I tried to use the shortcode for calculator plus so I use it to solve for the interest rate but it had another calculator? Could you tell me what is the correct shortcode?

    • Hi Chris, I see I have an error in the documentation that I need to fix.

      For this plugin FC Loan Calculator Plus, this is the shortcode example:

      [fcloanplusplugin sc_size="medium" sc_custom_style="no" sc_add_link="Yes" sc_brand_name="Your Brand Name Here If Desired" sc_hide_resize="No" sc_loan_amt="31500" sc_n_months="60" sc_rate="5.75" sc_pmt="0.0"]

      This is the minimum:

      [fcloanplusplugin]

      Make sure you have downloaded the plugin from the above link (not from what’s in the WordPress Plugin directory).

  5. THANK YOU!!
    Providing this calculator helped me figure out the payments on a current loan I have, had been applied incorrectly (as I suspected).
    I can, now, take my findings and prove to the loan company they owe me a couple thousand dollars – not to mention, my chart shows that my extra payment (when applied properly) shortened my loan payments by one year.
    I can’t thank you enough for providing such a tool for those of us who “know better” but aren’t quite sure how to apply the proper math to get the results we are seeking – God Bless You!!

  6. Karl, I love this calculator and am using it to track my periodic extra principal payments on my mortgage. I noticed that the schedule after applying an extra principal payment doesn’t adjust the “last payment due” date to when you’ve paid the last payment (it should be earlier than the original date) and the “total all payments” shouldn’t include those payments when the balance goes below zero – are you thinking of making these adjustments?

    • Well thank you. I’m rather partial to it too. 😉

      About adjusting the last date, there are several details to understand. First, if you have not expanded the rows, that is, the last row has a value in the "# Periods" greater than one, just set this to "Unknown" after you enter the extra payment and recalculate. The term will be readjusted to reflect your extra payments.

      If you have expanded the rows so that each row represents a single payment, then there is no way for the calculator to reliably drop off the end payment(s). The calculator is designed so users can record individual payments on the dates they are made. If a payment results in an overpayment, then we want the calculator to reflect that with a negative balance. This is why the calculator doesn’t remove single payments, even when fewer payments are needed.

      So probably what you want to do is to add your extra payments and after the last extra payment, add one more row with the regular payment amount and with an unknown number of periods. Calculate and that will give you a nice clean schedule.

      Will that work for you?

  7. Karl,

    Is there a tutorial I can look at to calculate IRR with uneven cashflows? Ideally something that shows how to incorporate additions and withdraws. Thanks

    • Hi Andrew, No, there isn’t one single tutorial for that. However, to calculate the IRR, click on "Settings" and then "Analytics" and check the "IRR" option. This causes the IRR to be calculated and visible on all schedules.

      Read tutorial #1 for an overview of the calculator. Then tutorial #25 discusses irregular cash flow with a mortgage as an example. You can apply the technique to an investment cash flow as well. Let me know if you have questions.
