FC's Auto Loan Calculator

Description

The FC Auto Loan Calculator calculates the monthly payment as well as the affordable car price, down payment required or the loan amount. It will create a detailed amortization schedule with date based payments as well as a set of colorful charts. A site’s users can select their own currency and date convention used in loan schedule. Ideal if site attracts visitors from around the globe. Four predefined sizes or modify CSS file to customize size and colors. Supports touch and a responsive designed website. Auto Loan Calculator Plugin is based on and uses the code from my Auto Loan Calculator.

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

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

Installation

Either (a) upload the fc-auto-loan-calculator folder with all its files to the /wp-content/plugins/ folder or (b) unzip the plugin’s zip file in the /wp-content/plugins/ folder.

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

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. If you are using widgets, just add the plugin to the sidebar through the Appearance -> Widgets menu in WordPress. Be sure to click Save.
  2. Add the following code <?php show_fcautoloan_plugin(); ?> to your template where you want the calculator to appear. See below for options.
  3. Add the shortcode [fcautoloanplugin] 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_price=
* sc_dwn_pmt=
* sc_loan_amt=
* sc_n_months=
* sc_rate=

Examples (1st includes all options):

[fcautoloanplugin sc_size="medium" sc_custom_style="No" sc_add_link="No" sc_brand_name="" sc_hide_resize="No" sc_price="35500.0" sc_dwn_pmt="4000.0" sc_loan_amt="0.0" sc_n_months="60" sc_rate="5.5"]

[fcautoloanplugin sc_size="small" sc_custom_style="Yes" sc_hide_resize="Yes"]

[fcautoloanplugin sc_custom_style="No" sc_add_link="Yes" sc_brand_name="Friendly Auto Dealer" sc_hide_resize="Yes" sc_price="27500" sc_dwn_pmt="2000.0" sc_loan_amt="0.0" sc_n_months="48" sc_rate="5.5"]

Optional array parameter passed to show_fcautoloan_plugin()

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

<?php show_fcautoloan_plugin(array('op_size' => "medium",
        'op_custom_style' => "No",
        'op_add_link' => "Yes",
        'op_brand_name' => "Karl's",
        'op_hide_resize' => "No",
        'op_price' => "35000.00",
        'op_dwn_pmt' => "3500.0",
        'op_loan_amt' => "0.00",
        'op_n_months' => "60",
        'op_rate' => "5.5")); ?>

Notes:

  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 financial-calculators.com).
  2. When branding, the brand name will be added before “Auto Loan 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. 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 calculator’s modal may not work.

Roadmap:

  1. Redesign that allows multiple calculators to work on the same web page – completed v.1.2.0.
  2. Allow website owner to select a default currency and date format. (This can now be done by patching the code – contact me.)
  3. Give website owners the ability to not let their visitors change the default date format or currency.

Contact me if you would like to help test any of these new features.

FAQ

Can the Auto Loan Calculator plugin be used on a commercial website?

Yes. I would be honored. Thanks.

Also, if you happen to be a financial blogger, I would encourage you to add a “Calculators” or “Tools” section to your site and include all my calculators. More content equals more opportunity. I expect to have six free plugins by early 2017.

Does your plugin have any embedded advertising?

Absolutely not.

Is your plugin self contained?

Yes. 100% of the plugin is installed on your server. There are no external dependencies.

Does the plugin include any backlinks?

No, not by default. If you decide to brand the calculator with your brand and / or set the add_link option to Yes, one discreet link is added to my site. (User will not know there is a link unless their mouse passes over it.) The link is around the copyright in the lower left. 🙂

Is the calculator plugin responsive?

Yes. In fact, I use it on a Bootstrap responsive site.

Does the calculator support touch devices?

Yes. Users use the calculator with all types of devices.

Do you offer other calculator plugins?

Yes. I have a conventional Loan Calculator hosted in this directory. And here is my widgets and plugin page where you’ll find other free plugins as well as some “plus” versions which are free for a limited time only.

I like your plugin and I’d like to contribute something but I notice you don’t have a link for contributions, why not?

Thank you. That’s very kind of you. Actually, you can contribute, and it won’t cost you a cent. Please stop by my website and check it out. In addition to providing some very advanced calculators, I think that I’m the only one who hosts a public question and answer site to provide support for their calculators. Take a look, and if you like what you see, please spread the word. That’s better than any monetary compensation.
