After configuring the parameters, use one of the function menus noted below to perform the corresponding calculation.

{SI} … {simple interest}

{SFV} … {simple future value}

An error (Ma ERROR) occurs if parameters are not configured correctly.

Use the following function menus to maneuver between calculation result screens.

{REPT} … {parameter input screen}

{GRPH} … {draws graph}

After drawing a graph, you can press (TRCE) to turn on trace and read calculation results along the graph.

Each press of C while trace is turned on cycles the displayed value in the sequence: present value (PV) μ simple interest (SI) μ simple future value (SFV). Pressing B cycles in the reverse direction.

3. Compound Interest

This calculator uses the following standard formulas to calculate compound interest.

SPV, PMT, FV, n

I % ξ 0

 

 

 

 

 

 

 

PV + FV

 

PV = – ( PMT +  FV)

PMT = –
