touchTVM

This easy-to-use application allows you enter any three of the four loan values and compute the fourth. You can calculate payment for a given rate, loan amount and number of payments; enter the three values you know and hit the Payment button to compute your payment.

Or, if you need to know how much you can borrow for a given rate, payment and number of payments, you can compute that as well; enter the three values you know, then hit the Loan Amt button to compute how large a loan you can afford.

Use the +/– buttons on either side of any of the values to increment and decrement the values without using the keyboard.

Or, simply tilt your phone right or left to do the same for the currently active field (shown in light blue text.)

Default +/– increment values for each field can be set through Settings application or by using the info icon located in the lower-right corner of the main screen.

To use the calculator for data entry just touch the text of the value you want to edit.
