A simple PHP CLI script to calculate interest on interest on a savings account

Interest On Interest

This is a simple function I've made with PHP to calculate interest on interest. It's nothing fancy at all, but maybe it will be useful to someone. I've made it while learning PHP.

Usage

The script can be run both from a browser and from the terminal.

CLI usage

First argument to the script is the amount of money on your savings account, the second argument is the interest (without the percent sign) and the third (optional) argument is the number of years. For example if you have 50.000 in your savings account, and the interest is 3% and you want to know how much money you will have after 8 years:

php interest.php 50000 3 8

If you leave out the number of years the script will calulate the savings after one year.

Browser usage

Just put the script on a webserver with PHP and run access it from your browser. Then fill in the form and hit 'Calculate' and the script will calculate your savings for you.

Please note that the script does NOT do any form of data validation!
