BA II PLUS: dividing the nominal rate twice

Entering a quarterly rate into a nominal I/Y field while retaining quarterly settings changes the model again.

On this page

State the intended quotation

A nominal annual rate of 6% compounded quarterly implies 1.5% per quarter. The TVM state I/Y = 6, P/Y = 4 and C/Y = 4 represents that quotation. The rate is entered as a percentage number, not the decimal 0.06.

Inspect the altered input

Replacing I/Y = 6 with I/Y = 1.5 while retaining P/Y = C/Y = 4 implies 0.375% per quarter under this matched-frequency model. That is not the intended quarterly factor 1.015.

Choose one consistent representation

Use the nominal annual quotation with matching device frequencies, or deliberately build an explicit per-period representation with a corresponding state. Record which representation you chose. Do not divide automatically simply because the question mentions quarters.
