This plugin adds a mortgage and loan calculator to your WordPress site, as a Gutenberg block, a sidebar widget or the [mlcalc] shortcode. Visitors enter the purchase price or loan amount, down payment, rate and term, then press Calculate to see a summary, a chart and an amortization schedule in a popup. It is built for mortgage loan officers, real-estate agents and finance or home-buying sites.

The calculation and the results popup are provided by the MLCALC.com service, which means the calculator needs an internet connection and sends the entered values there when Calculate is pressed (see External services below).

External services

This plugin relies on the MLCALC.com calculator service to compute and display results. When a visitor presses “Calculate”, the values typed into the form (purchase price or loan amount, down payment, term, interest rate, property tax, insurance, PMI, start date, currency and language) are sent to https://www.mlcalc.com/ and the results page opens in a popup window served by mlcalc.com. Nothing is sent until the visitor submits the form, and no personal data is collected. The service is provided by ARSIDIAN LLC: Terms of use, Privacy policy.

1. Upload the mortgage-loan-calculator directory (including all files within) to the /wp-content/plugins/ directory.
2. Activate the mortgage calculator plugin through the ‘Plugins’ menu in WordPress.

Usage

• If you are using widgets, just add the Mortgage Calculator to the sidebar through the Appearance -> Widgets -> Mortgage Calculator menu in WordPress.
• Add the following code: <?php display_mlcalc(); ?> to your template where you would like the mortgage loan calculator form to appear.
• Add the shortcode [mlcalc] to your page or post and configure default mortgage parameters.

1. 

   The mortgage calculator form with property tax, insurance and PMI fields.

2. 

   The result: monthly payment breakdown, loan balance chart and payment totals.

3. 

   The Mortgage Calculator block in the block editor, with its settings in the sidebar.

How do I add the mortgage calculator to a page?

In the block editor add the “Mortgage Calculator” block and set its options in the sidebar. You can also paste [mlcalc] into the page or post (or into a Shortcode block). To start with specific values, add attributes, for example [mlcalc default="mortgage" price="400,000" rate="6.5" down="20"].

How do I show only the mortgage calculator, or only the loan calculator?

Use default="mortgage_only" or default="loan_only". With default="mortgage" or default="loan" both calculators are available and the chosen one is shown first.

Does it calculate PMI and property tax?

Yes. The mortgage form has fields for property tax, home insurance and PMI, which you can preset with the tax, insurance and pmi attributes.

Which languages and currencies are supported?

English, German, Spanish, French, Italian, Russian, Portuguese and Albanian, set with the language attribute (or the widget settings). Currencies: usd, eur, gbp, or any currency code of your own.

Does it send data to an external service?

Yes. When a visitor presses Calculate, the numbers typed into the form are sent to MLCALC.com, which returns the results popup. Nothing is sent before that and no personal data is collected. See the External services section for details and links.

Does it work offline?

No. The results are produced by MLCALC.com, so the visitor needs an internet connection.

May I use your widget on my commercial website

Yes. Absolutely.
