FC’s Retirement Savings Calculator



Retirement Savings Calculator easily answers this question, How much do I need to save or invest each month to reach my retirement goal?. The calculator answers the question and creates a detailed schedule with projected date based investments and charts. A sites 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. This plugin is based on and uses the code from my Retirement Calculator.

Rebranding with your sites brand name is supported and encouraged.

The plugin may be used (a) in a post or pages content area via a shortcode; or (b) used in a widget area; or (c) called from any template file. See usage under installation for details.


Either (a) upload the fc-retirement-savings-calculator folder with all its files to the /wp-content/plugins/ folder or (b) unzip the plugins zip file in the /wp-content/plugins/ folder.

Activate the plugin through the Plugins -> Installed Plugins menu in WordPress


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. If your theme supports widgets, add the plugin to a widget area through the Appearance -> Widgets menu in WordPress. WordPress v5.8 introduced the block editor to the Admins widget management screen. To install this plugin as a widget in WordPress v5.8 or later, install first the widget shortcode and then copy this plugins shortcode into it.
  2. Add the following code to your template where you want the calculator to appear. See below for options.
  3. Add the shortcode [fcretiresavingsplugin] in the content area of your page or post and configure shortcode parameters.

Shortcode parameters

* sc_size= tiny | small | medium | large * sc_custom_style= No | Yes * sc_add_link= No | Yes * sc_brand_name=  * sc_hide_resize= No | Yes * sc_save_amt= * sc_n_months= * sc_rate= * sc_current_age= * sc_retire_age= * sc_current_savings= * sc_rate= * sc_goal_amt= * sc_currency= * sc_date_mask=

Optional array parameter passed to show_fcretiresavings_plugin()

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

 "large",     'op_custom_style' => "No",     'op_add_link' => "No",     'op_brand_name' => "",     'op_hide_resize' => "No",     'op_current_age' => "28",     'op_retire_age' => "66",     'op_current_savings' => "18000",     'op_rate' => "5.5",     'op_goal_amt' => "1000000.0",     'op_currency' => "999",     'op_date_mask' => "999"     )); ?> 


  1. If you want to add your brand to the calculator, the *_add_link option must be set to Yes (i.e. create a subtle follow link to
  2. When branding, the 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 plugins 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. size (max-width): large: 440px, medium: 340px, small: 290px, tiny: 150px
  6. The modal dialog that allows users to select a default currency and date format is NOT compatible with some other dialogs. If you have a modeal on the webpage you want to install this calculator on, either your modal or the calculators modal may not work.
  7. Website developers can set a default currency sign and preferred date format by setting _currency and _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 plugins root folder. (example: India, Indian Rupee: ?1,23,45,678.99 = 83)

Enhanced Internationalization

Support for over 90 currency signs (using appropriate nummber formatting conventions) and 6 date formats (mm/dd/yyyy, dd/mm/yyyy, etc.). If neither the website developer or the user makes a selection, the calculator will read the browsers 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 visitors 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 websites selection.
  3. Otherwise, the calculator plugin will attempt to read the browsers 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 : Franais
de : German : Deutsch
hu : Hungarian : Magyar
it : Italian : Italiano
lt : Lithuanian : Lietuvi?
pl : Polish : Polski
pt : Portuguese : Portugus
ro : Romanian : Romnesc
ru : Russian : ???????
es : Spanish : Espaol
sv : Swedish : Svenska

Notes: (1) The plugin depends on the sites 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 sites language setting is Portuguese (Portugal) which is local pt_PT. But if your site is in Brazil, youll need to rename the plugins 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, Ill regenerate the .MO, and if needed the .JSON files for you.

I am making the other calculators at my website available free-of-charge to bloggers who are abe to help with translation. See the website for details.
