IGraphing in the TVM Mode

After performing a financial calculation, you can use (GRPH) to graph the results as shown below.

•Pressing (TRCE) while a graph is on the display activates Trace, which can be used to look up other financial values. In the case of simple interest, for example, pressing C displays PV, SI, and SFV. Pressing B displays the same values in reverse sequence.

•Zoom, Scroll, and Sketch cannot be used in the TVM mode.

•Whether you should use a positive or a negative value for the present value (PV) or the purchase price (PRC) depends on the type of calculation you are trying to perform.

•Note that graphs should be used only for reference purposes when viewing TVM mode calculation results.

•Note that calculation results produced in this mode should be regarded as reference values only.

•Whenever performing an actual financial transaction, be sure to check any calculation results obtained using this calculator with against the figures calculated by your financial institution.

2.Simple Interest

This calculator uses the following formulas to calculate simple interest.

SFormula

365-day Mode	SI' =		n	⋅ PV ⋅ i	i =		I%	SI	: interest
			365				100
			n	⋅ PV ⋅ i			I%	n	: number of interest periods
360-day Mode	SI' =				i =			PV	: principal
		360				100
								I% : annual interest
	SI = –SI'							SFV : principal plus interest
	SFV = –(PV + SI' )

Press (SMPL) from the Financial 1 screen to display the following input screen for simple interest.

(SMPL)

n........... number of interest periods (days)

I% ........ annual interest rate

PV ........ principal
