The Nominal function returns the nominal annual interest rate.

Lending institutions advertise the nominal rate of their loans. The nominal interest rate does not take into account the effect of compounding. The effective interest rate takes the compounding period into account, and it is a more accurate measure of interest charges.

Syntax

Nominal(effective_rate, num_per_year)

Function arguments:

effective_rateThe effective interest rate as a decimal (for example, for 7%, input 0.07).
num_per_yearThe number of compounding periods per year.

Notes

The general formula for the Nominal function is:

Examples

Nominal(.07, 12)

The nominal annual interest rate for an effective rate of 7%, paid 12 times a year (monthly). This example returns 6.78%.

Nominal(0.7, 26)

The nominal annual interest rate for an effective rate of 7%, paid 26 times a year (bi-weekly). This example returns 6.77%.

Nominal([Effective Rate], [Number of Periods])

You can use the nominal function to explore the change in the nominal interest rate based on the number of times it compounds.
