Variables used in ﬁnancial calculations

Financial calculations use multiple variables. By entering known values into variables, you can obtain unknown values. Variables used in ﬁnancial 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.

Listed ﬁnancial variables:

Variables that are organized into lists in different categories. These variables can be accessed using the z/ icursor keys in each calculation. P/Y and C/Y in the TVM solver are of this type of variable.

Variables shared among calculations

Financial variables are speciﬁc to the type of calculation they are used in. Values are stored in these variables and recalled as required. Some variables are shared (in the memory area) among calculations. If you change the value of a variable in one calculation, the value will change in all the other calculations as well. The following list shows the variables shared between calculations. While calculating, be aware of the values stored in these variables.
