Variables used in fi nancial calculations
Financial calculations use multiple variables. By entering known 
values into variables, you can obtain unknown values. Variables 
used in fi nancial calculations are categorized into the following 
two types, depending on the entry method.
TVM variables:
Variables that are used in the TVM solver. These include N, 
I/Y, PV, PMT and FV. You can store, recall or calculate values 
directly using the corresponding keys.
