The original and #1 loan calculator in the App Store!

Save yourself time and money (potentially even thousands of dollars) using the What If Loan Calculator. In seconds you'll be able to calculate the monthly payment for any fixed rate loan, including mortgage, auto, credit card, etc. You'll also be able to calculate "what if" scenarios to determine how additional monthly or yearly payments will help you pay off your loan early and save money in interest. And you'll be able to view a handy amortization/payment schedule showing how much of your loan's principle and interest will be paid each month.

If you're shopping for a home or car, thinking of refinancing, or want to see how you can save money, this application is a must-have.

Ratings and Reviews

Excellent app


This is perhaps the best app in this category. It is very easy to use and the fact that it also provides a table, detailing the monthly interest and capital payments sets it apart from others. I also like the fact that you have the option of adding extra monthly and/or yearly payments. Well done to the producers.

Good app


Breaks the interest down into a table showing exactly what interest your paying each month & also has an extra option if you paid £££ extra each month the total savings you would make.

I love this app


It has all the normal loan calculator features and it shows how you will benefit by making extra payments. I use this app frequently to motivate myself to pay extra on my debt to save time and money. I highly recommend this app.
