I just purchased your extension, NS Formula. I need some help with what code to use in the results for a mortgage calculator. I found this javascript online:

Formula: Monthly Payment = Loan amount * ((1 + Interest rate per annum/100) ^ Term of loan) / Term of loan / 12

How would this translate to the code examples your site shows.

Actually what I need to replace is a mortgage loan calculator on the website indicated below because it won't run in PHP 7.x. It only runs in PHP 5.6 and we're updating the site.

Thanks in advance for your help.

Warm regards,

Jeanne
