12×

In-line multiplication when entering a value into the Number of Payments TVM register. Typically, the effect of this key is to convert a period specified in years into one specified in months, which is simultaneously entered to the n register.

12÷

In-line division when entering a value into the Interest TVM register. Typically, the effect of this key is to convert a yearly rate into a monthly one when working with U.S. annual percentage rates. European and Canadian users should generally use the [EMR] key instead.

AMORT

Performs loan amortization. For a detailed description of this function, refer to Amortizing Loan Payments.

CFPV(-)#

Returns the Present Value of negative only cashflows (outlays). CFPV(-)# is accessible by pressing the [NPV] key. For detailed information, refer to Discounted Cashflow Calculations.

CFPV(+)#

Returns the Present Value of positive only cashflows (inflows). CFPV(+)# is accessible by pressing the [NPV] key. For detailed information, refer to Discounted Cashflow Calculations.

CF0

The [CF0] button clears the data in the cashflow list and enters the current value as the first amount. For further information, refer to Discounted Cashflow Calculations.

CFj

The [CFj] appends the current display value to the cashflow list. For further information, refer to Discounted Cashflow Calculations.

DB

Calculates depreciation using the Declining Balance method. For detailed information, refer to the Depreciation section.

EAR

Returns the Effective Annual Rate given a monthly input value. For further information, refer to Effective Annual Rates in the US, Europe & Canada.

EMR

FV

Future Value Register. For a complete description, refer to Compound Interest Calculations.

i

Interest Rate Register. Value is expressed as a percentage. For a complete description, refer to Compound Interest Calculations.

INT

Calculates Simple Interest. The accrued interest is calculated both for a 360-day and 365-day basis simultaneously. It uses the values stored in the TVM registers as follows: the number of days n, annual interest rate i and principal amount PV. The 360-day result is returned directly, and places the result of the 365-day calculation is stored in the K memory register. If you are working in RPN mode, the 365-day result is also placed in the Y stack register.

Example: Your friend asks you for a loan of $450 to start her own company, and agrees to pay you back in 150 days at a 6% simple interest rate to be calculated on a 360-day basis. What is the amount of accrued interest she will owe you in 150 days, and what is the total amount owed? Assume you are using Reverse Polish Notation.

150 [n] (stores 150 days)
6 [i] (stores interest rate)
-450 [PV] (stores amount loaned out)
[INT]
Displays: 11.25 (accrued interest on a 360-day basis)

[RCL] [PV] (recalls principal loan amount)
[+/(-)] (make sign consistent)
[+]
Displays: 461.25 (total owed)

IRR

Calculates the Internal Rate of Return, given a series of cashflow values. For more information, refer to Discounted Cashflow Calculations.

MIRR

Modified Internal Rate of Return, calculate for a series of cashflow values and rates for finance and re-investment risk. For more information, refer to Discounted Cashflow Calculations.

n

Number of Payments Register. For a complete description, refer to Compound Interest Calculations.

Nj
