Calculating Interest Conversion
Calculating an Interest Conversion
Use the interest conversion functions (menu items B and C) to convert interest rates from an annual
effective rate to a nominal rate (4
Nom( ) or from a nominal rate to an annual effective rate (4Eff( ).
4
Nom(
4Nom( computes the nominal interest rate. effective rate and compounding periods must be real numbers.
compounding periods
must be >0.
4
Nom(effective rate,compounding periods)
4Eff(
4Eff( computes the effective interest rate. nominal rate and compounding periods must be real numbers.
compounding periods must be >0.
4Eff(nominal rate,compounding periods)
Finding Days between Dates/Defining Payment Method
dbd(
Use the date function dbd( (menu item D) to calculate the number of days between two dates using
the actual-day-count method. date1 and date2 can be numbers or lists of numbers within the range of
the dates on the standard calendar.
Note: Dates must be between the years 1950 through 2049.
dbd(date1,date2)
You can enter date1 and date2 in either of two formats.
• MM.DDYY (United States)
• DDMM.YY (Europe)
The decimal placement differentiates the date formats.
Defining the Payment Method
Pmt_End and Pmt_Bgn (menu items E and F) specify a transaction as an ordinary annuity or an annuity
due. When you execute either command, the TVM Solver is updated.
