This plugin is also available for download at WordPress.org Plugin Directory

This plugin answers a question most people ask at one time or another, "Assuming regular investment amounts, how much will I have when I retire?". The calculator quickly answers the question based on the variables your users enter and creates a detailed schedule with projected date based investments and charts. A site's users can select their own currency and date convention used in the investment schedule. This is ideal if your site attracts visitors from around the globe. Select from four predefined sizes or modify CSS file to customize size and change colors. Supports touch devices and a responsive designed website. The FC Retirement Nest Egg Plugin Calculator is based on and uses code from the very popular Retirement Calculator.

Rebranding with your site's brand name is supported and encouraged.

The plugin may be

  1. used in a post or page's content area via a shortcode; or
  2. used in a sidebar widget area; or
  3. called from any template file.

Installation

  1. Either
    1. upload the fc-retirement-nest-egg-calculator folder with all its files to the /wp-content/plugins/; or
    2. unzip the plugin's zip file in the /wp-content/plugins/  folder.
  2. Activate the plugin through the Plugins Installed Plugins menu in WordPress

Upgrading: If you've translated the plugin from English to another language, please backup your work prior to upgrading the plugin.

Usage

There are 3 mutually exclusive ways you can deploy the calculator to an individual page (though you can use all three methods on different pages within a site):

  1. Add the shortcode [fcretirenesteggplugin] in the content area of your page or post and configure shortcode parameters.
  2. Add the following code to your template where you want the calculator to appear.
    • <?php show_fcretirenestegg_plugin(); ?>
  3. If you are using widgets, just add the plugin to the sidebar through the Appearance Widgets menu in WordPress. Be sure to click Save.

Shortcode parameters

  • sc_size= "tiny" | "small" | "medium" | "large"
  • sc_custom_style= "No" | "Yes"
  • sc_add_link= "Yes" | "No"
  • sc_brand_name="Your Name"
  • sc_hide_resize= "No" | "Yes"
  • sc_current_age=
  • sc_retire_age=
  • sc_current_savings=
  • sc_invest_amt=
  • sc_rate=
  • sc_currency=
  • sc_date_mask=

Shortcode Examples:

advertisement

Copy and paste to page's or post's content area.

First example includes all options.

[fcretirenesteggplugin sc_size="tiny" sc_custom_style="No" sc_add_link="Yes" sc_brand_name="Your Name Here" sc_hide_resize="No" sc_current_age="29" sc_retire_age="62" sc_current_savings="17000" sc_invest_amt="755.0" sc_rate="5.25" sc_currency="83" sc_date_mask="2"]
[fcretirenesteggplugin sc_size="small" sc_custom_style="Yes" sc_hide_resize="Yes" sc_currency="83" sc_date_mask="2"]
[fcretirenesteggplugin sc_custom_style="No" sc_add_link="Yes" sc_brand_name="Friendly Financial" sc_hide_resize="Yes"]

Optional array parameter passed to
show_fcretirenestegg_plugin()

This can be copied and pasted to a template part.

Valid values for options are the same as the shortcode above.

<?php show_fcretirenestegg_plugin(array( 'op_size' => "medium", 'op_custom_style' => "No", 'op_add_link' => "Yes", 'op_brand_name' => "", 'op_hide_resize' => "No", 'op_current_age' => "28", 'op_retire_age' => "62", 'op_current_savings' => "18000", 'op_invest_amt' => "750.0", 'op_rate' => "5.5", 'op_currency' => "999", 'op_date_mask' => "999")); ?>
Notes:
  1. If you want to add your brand to the calculator, the add link option must be set to "Yes".
  2. When branding, your brand name will be added before "Retirement Calculator".
  3. If custom style is set to "Yes", the plugin will load fin-calc-widgets-custom.css located in the plugin's CSS folder. If you set the option to "Yes" without making any changes, the calculator will change to a horrendous red which indicates the custom css is being used.
  4. The plugin is built and tested on HTML5/CSS3 pages.
  5. max-width: large: 440px, medium: 340px, small: 290px, tiny: 150px
  6. New: Website developers can set a default currency sign and preferred date format by setting <op /sc>_currency and <op /sc>_date_mask respectively. Set one or both to an integer value. For the list of integers to support 90 plus currency symbols and 6 date format options, see the file currency_and_date_conventions.txt in the plugin's root folder. (example: India, Indian Rupee: ₹1,23,45,678.99 = 83)
Enhanced Internationalization

New: Support for over 90 currency signs (using appropriate nummber formatting conventions) and 6 date formats (mm/dd/yyyy, dd/mm/yyyy, yyyy.mm.dd etc.). If neither the website developer or the user makes a selection, the calculator will read the browser's default currency and date options and automatically use them. Without doing anything, a website visitor from Japan visiting a website hosted in France will initially see a floating yen sign. The website developer can easily override this default behavior by setting either shortcodes or function options. The user (if the website designer keeps the feature enabled) can override both and select a currency and date format.

To summarize, the plugin determines what currency symbol (and date format) to use by applying the following rules:
  1. If a website allows a user to select a symbol, and the user makes a selection, the plugin uses the visitor's choice first.
  2. Otherwise, if a user has not made a selection, and the website owner has set a default currency (i.e., currency does not equal 999), the calculator uses the website's selection.
  3. Otherwise, the calculator plugin will attempt to read the browser's currency default and pick a currency symbol.
  4. Otherwise, the plugin defaults to using the '$' symbol.
Language Translations

New in v1.5, support for 14 languages in addition to English. The plugin also includes a translation template file (.POT) in the "languages" folder. Using a POT/PO file editor, website owners can translate this plugin to any language supported by WordPress.

The supported languages are:

  • da : Danish : Dansk
  • nl : Dutch : Nederlandse
  • fi : Finnish : Suomalainen
  • fr : French : Français
  • de : German : Deutsch
  • hu : Hungarian : Magyar
  • it : Italian : Italiano
  • lt : Lithuanian : Lietuvių
  • pl : Polish : Polski
  • pt : Portuguese : Português
  • ro : Romanian : Românesc
  • ru : Russian : Русский
  • es : Spanish : Español
  • sv : Swedish : Svenska

Notes: (1) The plugin depends on the site's "Site Language" setting to display to your visitors the correct language. The files in the language folder can be renamed if needed. For example, if you want the plug to display in Portuguese the .MO and .JSON files include assume your site's language setting is Portuguese (Portugal) which is local pt_PT. But if your site is in Brazil, you'll need to rename the plugin's language files to use pt_BR. (2) At this time, these translations were computer generated. A fluent speaker can edit the included .PO file and regenerate the .MO file to update the tranlation. (3) If you are willing to allow me to include your edits with the plugin, I'll regenerate the .MO, and if needed the .JSON files for you.

I am making the other calculators available free-of-charge to bloggers who are able to help with translation. See this page for details.

10 Comments on “Retirement Nest Egg Plugin”

Join the conversation. Tell me what you think.
  • Sadly, I am no longer able to use this on my website. For whatever reason the calculator stopped working.
    It no longer shows any computations in the results section.

    It says this on the plugin details:
    Warning: This plugin has not been tested with your current version of WordPress.

    I can confirm that it does not seem to work for current version 5.9

    • I’ve tested the plugins on my development computer and they all run just fine with v5.9.

      Can you give me a link to the plugin on your site and I’ll take a look?

      Also, I assume you are running the latest version of the plugin?

      • I just took it off my site. I also uninstalled and reinstalled the plugin. It still did not work.

        https://www.mmwealth.com/retirement-calculator-how-much-will-i-have/

        • You have a problem on your site with

          "Uncaught SyntaxError: Unexpected end of input"

          with something called:

          "autoptimize_fb308b57…4810294d124f.js:329"

          Do you know what autooptimize FB is? Can you disable that and try again?

          You can see the error message by pressing F12 and in the window or panel that opens, click on "Console."

      • So I deactivated Autooptimize and it did allow the calculator to work. Autoptimize is a site optimizer. Not sure what in the calculator page component is causing an issue.

        Autoptimize

        Makes your site faster by optimizing CSS, JS, Images, Google fonts and more.

        Version 2.9.5.1 | By Frank Goossens | Autoptimize.com

        • I see. I can guess, one of two things (but it’s only a guess since I obviously didn’t write Autoptimize), either this version of Autoptimize has a bug, or it is trying to optimize the retirement plugin.

          If you have control over what Autoptimize optimizes, then don’t let it try to optimize the calculator plugin. The plugin is already optimized.

          Or if you have been using Autoptimize for a while with no issues, and just updated it, roll back the update. There might be a bug in it.

          What happening with that message is, the error is causing the JavaScript runtime interpreter to crash, and that prevents the calculator from working because it relies on JavaScript. But you can see, that the calculator plugin is compatible with WordPress v5.9.

      • Yes I was able to add a per page setting and disable the JS optimization for that page.

        Thank you!

  • Hi Karl,

    Do you build custom calculators? We love your nest egg calculator and would love to add a few more sections for compliance purposes. Thank you

    • Hi Tanesha, I had replied privately a day or so ago. I do, but at the moment I’m booked. What’s your timeline? You can reach me via the email address on the contact page. There’s a link to that page at the bottom of every page.
