Mortgage Calculator

This plugin provides a very simple and easy to use mortgage calculator widget.

I tried to provide a bloat-free mortgage plugin that serves the purpose in a quality way.

This mortgage plugin is also translation ready and you can translate it to your language using pot file provided in languages directory.

External services

This plugin works entirely in the visitor’s browser: the monthly payment is calculated with JavaScript and nothing is sent to a server while the calculator is used.

The only external service is the optional “Amortization Schedule” link shown under the result. When a visitor clicks it, the calculator sends the entered loan amount, down payment percentage, interest rate and loan term to mlcalc.com (operated by ARSIDIAN LLC), which displays the amortization schedule and chart in a popup. No personal data is sent; the request is made only on that click, never on page load.

• Service: https://www.mlcalc.com/
