Inputting Values
A period (
n ) is expressed as a positive value. Either the present value ( PV ) or future value
(
FV ) is positive, while the other ( PV or FV ) is negative.
Precision
This calculator performs interest calculations using Newton’s Method, which produces
approximate values whose precision can be affected by various calculation conditions.
Because of this, interest calculation results produced by this calculator should be used
keeping the above limitation in mind or the results should be verified.
After configuring the parameters, use one of the function menus noted below to perform the
corresponding calculation.
• { n } … {number of compound periods}
• { I% } … {annual interest rate}
• { PV } … {present value} (Loan: loan amount; Savings: principal)
• { PMT } … {payment} (Loan: payment; Savings: deposit)
• { FV } … {future value} (Loan: unpaid balance; Savings: principal plus interest)
• { AMORTZN } … {amortization screen}
• An error occurs if parameters are not configured correctly.
Use the following function menus to maneuver between calculation result screens.
• { REPEAT } … {parameter input screen}
• { AMORTZN } … {amortization screen}
• { GRAPH } … {draws graph}
After drawing a graph, you can press !1(TRACE) to turn on trace and read calculation
results along the graph.
Press J to return to the parameter input screen.
