Here there in this article I would like to share with you a program that will help you compute the compounded interest in a loan you have made from a bank or financial institution. I called this program Compound Interest Calculator written entirely in PHP. What does our program will do is to ask the user the principle amount that is being loan by person, the number of years to be paid and the yearly interest rate for the said load. Every year it will be computed by our program for our user. This can be helpful for planning for the payment of the loan of the user in the future. I have a great time writing this program I hope this program will help you in your financial management.
If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.
People here in the Philippines who wish to contact me can reach me at my mobile number 09173084360.
