Nominal Rate Converted to Effective Rate
Given a nominal interest rate and the number of compounding periods per year,
this keystroke procedure computes the effective annual interest rate.
1. Press g and fCLEARG.
2. Key in the annual nominal rate as a percentage, then press \.
3. Key in the number of compounding periods per year, then press nz¼.
4. Key in 100 then press Þ\$.
5. Press M+ to obtain the effective annual interest rate.
Example 1: What is the effective annual interest rate if the annual nominal rate
of 5¼% is compounded quarterly?
