If you would like to install any of these calculators on your website you have one of two options:
Option #1: You can install these calculators for free (see terms and conditions listed on demo pages).
Option #2: You can pay a small, one-time, commercial-use fee (see benefits listed on demo pages).
Either option will help you to attract new visitors to your website, as well as give your repeat visitors yet another reason to return more often.
If you would like the convenience of adding calculators to a shopping cart as you browse through them, it takes less than a minute to create a shopping cart. You can then browse through the calculators in the store which has less clutter and is much easier to navigate.
