(Last updated 2005-03-21 Open sourced)

#### What is ICalc

ICalc is a compounded interest calculator that can calculate any component of the compounded interest calculation.

#### Screen Shot #### Why this calculator, when so many others exist?

I am learning WTL which is an extention to ATL. As a learning exercise I decided to make something usefull.

#### Features

• Can be used to calculate loan data aswell as investment data.
• Calculates: Initial Amount - this is the amount you want to loan or the lump sum you have to invest.
• Calculates: Final Amount - this is the amount you owe or receive after your investment matures
• Calculates: Monthly Installment - this is the amount you must pay per month or the monthly return on your investment
• Calculates: Number of Months (Negative months were not tested, but it should work, should you be that weird!)
• Calculates: Interest per Year - due to the polynomial nature of the Interest formula some weird (typically negative interest rates) combinations may fail!
