Classic Financial II manual · Chapter 1 of 16

Getting started

The display, the 2ND key, a first calculation, clearing and editing, leaving a worksheet and using a laptop keyboard.

1.1What this calculator is for#

Classic Financial II answers money questions: what is the monthly payment on a loan, what will savings grow to, is an investment worth its price, how much interest is in a payment, how long between two dates. The keys in the top rows solve loans and savings directly. Everything else lives in worksheets, which are lists of labelled values that you step through with the up and down arrows.
