Why are popup calculators less costly than web calculators from so many other companies?

A.  After a popup calculator is installed it requires no additional effort on your part or on our part.  Popup calculators perform financial calculations based upon well-known mathematical formulas.  These mathematical formulas do not change.

Some software companies require annual license fees or require that their customers pay monthly hosting fees to connect to calculators on the companies' servers.  Not so with Popup-Calculators.com!  You get stable, proven financial calculators that you can install and forget while they continue to add value to your web site!

Will I pay for upgrades?

A.  No!  Upgrades are available at no additional charge.

Can I read the license agreement before I buy a calculator?

A.  Yes!  We encourage you to read the license agreement before you purchase.  It's available online at:  Popup-Calculators.com License Information.

How do I ask for help if I need assistance installing a popup calculator?

A.  Installation instructions are included with each Popup-Calculators.com web site calculator.  However, if you require support during the installation, please use our online contact form.

In addition to providing answers to your questions, we'll actually look at your web page and help you fix any problems with the installation code!

On what web servers will Popup-Calculators.com financial calculators work?

A.  Popup-Calculators.com™ financial calculators are designed to be server-independent.  These calculators are loaded from your web server with the web page and are displayed in your visitors' web browsers.  All of the calculations are performed on your visitors' computers and not on your web server.

Popup calculators can be installed on your web site hosted on any web server that will deliver content to web browsers.  They'll "run" on Unix, Linux, Apple or Windows®-based web server.

Does my web hosting account permit me to install a popup calculator?

A.  Professional-level hosting accounts do permit the installation of web pages.  In order to know for sure, the question to ask your web host is:  "Am I able to upload web pages to my web site?"  Your web host will have a ready answer.
