Solution 34792: Computing Nominal and Effective Interest Rates on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.
How do I compute the nominal and effective interest rates on the TI-83 Plus and TI-84 Plus family of graphing calculators?
The examples below will demonstrate how to calculate nominal and effective interest rates.
Use
the ►Nom() function to compute the nominal interest rate. The syntax
for this function is ►Nom(effective rate, compounding periods).
Use the ►Eff() function to compute the effective interest rate. The syntax is ►Eff(nominal rate, compounding periods).
To access these functions, press [APPS] [ENTER] and select [B: ►Nom(] or [C:►Eff(].
Examples:
Find the nominal rate of 25 effective rate with 2 compounding periods:
1) Press [APPS] [1].
2) Press [ALPHA] [B].
3) Press [(] [2] [5] [,] [2] [)].
4) Press [ENTER].
The result is 23.60679775
Find the effective rate of 8 with 12 compounding periods:
1) Press [APPS] [1].
2) Press [ALPHA] [C].
3) Press [(] [8] [,] [1] [2] [)].
4) Press [ENTER].
The result is 8.299950681
Please see the TI-83 Plus and TI-84 Plus Family guidebooks for additional information.
