Saving a Dollar a Day Calculator

Let's show off the flexibility of this calculator and have some fun while we are at it. (This is particularly fun to do with kids.) How much do you think you'll have if you save just a dollar a day for forty years - a working lifetime? What will be the gain on the savings? That is, how much of the final value will be from the daily dollar saved and how much will be from investment gain?

What do you think?

To try the dollar-a-day calculation, set the calculator this way. (Of course, set the dates as needed and change the interest rate to suite.)

	Savings on Hand (PV) (can be 0):    $0.00

	Periodic Savings Amount?:           $1.00

	Number of Periods to Save? (#):    14,600

	Annual Interest Rate?:               4.5%

	Goal Amount (future value)?:        $0.00

	Today's Date?:                 09/01/2019
	First Deposit Date?:           09/01/2019

	Deposit/Investment Frequency?:      Daily
	Compounding?:                       Daily

Note, I selected 4.5% as the interest rate, not that you will earn that on a bank's savings account. But it's about halfway between the rate-of-return on 10-year US treasury bonds and the average return for the US stock market.

I'll leave it to the reader to do the calculation.

But the interest earned from daily compounding is almost twice the amount the user invested!

This savings plan calculator provides the user with enough flexibility that you should be able to test just about any savings plan. You should find it relatively simple to answer the question, "how will my savings grow?"

    how to change currency “$” to INR

    • ‘INR’ is not currently supported. However, I could add it, but there are 2 issues. First, the number of characters that can be entered is limited. So adding INR reduces the number of digits by 2.

      Also, for Rupees, I guess you don’t use the decimal character? These calculators currently require it. Even if I added INR, you would only be able to enter INR100.00.

      Also, the Lakh causes a problem Even if the calculators showed INR, it would not display INR 1,50,000. The best I can presently do without a major rewrite is INR150,000.00

      So I’m not sure if that would be useful or not.

    • I should have also pointed out,that the is an option for no currency character. Perhaps that’s a solution for you?

  • Hello, is it possible to integrate this calculator in my own web page? I have a website made with wordpress and the FC’s Savings Calculator plugin for wordpress adapts perfectly but it would lack to be able to indicate a Savings on Hand and to be able to choose the Deposit / Investment Frequency and Compounding as in this plugin.

    Thank you very much in advance

    • Hi, this calculator is not a plugin. If you are interested in licensing a version of this calculator for your website, that can be done. Please contact me via the contact link at the bottom of any page.

  • Ghanshyam Sharma says:

    Hi Karl,
    When we try to integrate the savings plugin we are not getting all fields as shown on this page. Can you please guide us on where are we going wrong. Please see the link https://ibb.co/hKtV673 for the plugin after integration on our site.


  • Hello, can I use the WordPress Plugin in German or is it possible to translate manually ?

    • The calculator does not come with a German translation. It does include all the source code, so a developer that knows Germain would be able to easily translate it.

    Greetings @support, may you kindly help me with the savings calculator on my website and the text on the side are not showing and I would like to know what is the ZAR (R) currency for South Africa. Kindly see https://prnt.sc/1xxt0lx

    • You sent me a link to an image of the calculator. I can’t tell anything from that. I need to see the page it’s on.

      About the currency, yes, the website owner can change the default currency as can the site’s visitor. See the readme file, and if you have questions, ask a specific question. Otherwise, if I were to give you guidance here, I would just repeat what is already in the readme.

        Hi Karl, thank you for responding me and sorry for the image, the web page is pigup.co.za. Thank you for your warm support in advance.

        • Hi, you’re welcome.

          The problem is with an incompatible setting in your style.css file.

          Do you (or your programmer) know how CSS works?

          You have a .label class and in that class you have this setting:

          height: 15px;

          Can you make it higher, say 30px? Or better yet remove it.

          A lot of these options will change the way the plugin looks. You may want to change several of these.

          .label {
          width: 15px;
          height: 15px;
          background: #4DB7FE;
          border-radius: 100%;
          -webkit-box-shadow: 0px 0px 0px 7px rgb(77 183 254 / 20%);
          box-shadow: 0px 0px 0px 7px rgb(77 183 254 / 20%);
          -webkit-animation: marker-animation2 2.5s infinite;
          animation: marker-animation2 2.5s infinite;
          position: relative;

          In the next version of the plugin, I will try to change the plugin’s label so as not to be impacted by other .label values.

        • I’ll add one more thing. Normally, programmers do not set the "height" attribute. Usually, to get the desired height, developers set the top and bottom padding. If you or your programmer uses this approach for your site’s labels, I don’t think you’ll have any issues with the calculator’s labels.

          • Dolphas Sithole says:

            Hi Karl thank you for responding me and my apologies for the delayed response. Unfortunately I am not a techy guy but I did try my best to add your settings as per your instructions, I was unsuccessful instead I ended breaking the site a bit https://prnt.sc/1yoswry. I guess I will wait for your next upcoming update which I believe will solve the issue at hand.

            Thank you once again for offering us such powerful plugin.
