Interest Calculator

By Ed Stivala

Open iTunes to buy and download apps.


Interest Calculator is super flexible and yet extremely quick and easy to use. Calculate complex compound interest on both loans and savings.

One application that calculates both LOAN (mortgage or any other) as well as the future value of SAVINGS.


* Two Apps in One. The only compound interest calculator you need.
* Currency independent. Useful in any country
* Simple Interface. Life does not have to be complex and graphical
* Instant Calculations. Lets you make choices about your money fast
* International. With support for Canadian Mortgage rules and 360 day years.


Enter the amount you need to borrow, the period of time that you will repay the loan over and the interest rate that you are being offered. You instantly are given the likely monthly repayment based on monthly compound interest.

Short term car loan? Long term mortgage? No problem! Press the settings button to specify if this loan is over months or years. Keeps life simple and flexible for you.

*Canadian users: The setting screen in the loan calculator has a special feature for setting Canadian Mortgage rules where interest is compounded twice a year rather than monthly.


Enter the amount of your saving, the interest rate you are being offered and the length of time you can invest this money for. Pressing one button instantly shows you the total gross value of your investment at the end of the period. Assuming monthly compound interest.

Want more control? Press the savings button and you can customize the calculators compounding function to be either daily, monthly or annual compounding. For users that want to go further still you can specify the number of days in a year (some parts of the world use a 360 day commercial year for the purposes of daily interest compounding).

We believe in making software that is easy to use with settings that offer power and flexibility to users that need it. We believe in clutter free interfaces that make getting things done; fast, easy and pleasurable. After all that’s why you bought an iPhone right?
